As well, two of the isolates (no. The MIC determinations were repeated in five independent experiments. Heat to boiling to dissolve the … Refer to the product container label for lot specific cation concentration. The direct colony suspension method was used for inoculum preparation. Due to the lack of specific breakpoints for H. parasuis, a classification of the 46 field isolates into the categories susceptible, intermediate, and resistant could not be obtained, and percentages of resistances could therefore not be calculated. Proc. It should be noted that the QC strain A. pleuropneumoniae is also a fastidious bacterium, and susceptibility testing in VFM medium according to CLSI document VET01-A4 is recommended (17). This medium is supplemented with calcium and magnesium salts to produce correct MICs with aminoglycosides and Pseudomo- nas aeruginosa.1 However, this medium is not satisfactory for fastidious organisms such as S. pneumoniae. 1752 N St. NW Thermo Scientific™ Remel Mueller Hinton Broth is for the cultivation of a wide variety of microorganisms. Bacterial isolates. American Society for Microbiology, Washington, D.C. 6. A panel of 21 antimicrobials and antimicrobial combinations was included in the repeated tests, and two different incubation times, 16 to 20 h and 24 h, were analyzed. Antimicrobial Susceptibility Tests; dilution and disk diffusion methods. As O-A complex consists of two different components (oleic acid and bovine serum albumin) and therefore is a complex supplement to prepare, sterile filtered inactivated chicken serum together with NADH was chosen to supplement CAMHB for broth microdilution susceptibility testing of H. parasuis isolates. Although in H. parasuis endemic herds, young piglets are usually protected by maternal immunity, several environmental stress factors may lead to disease as well as infections of naive populations. H. parasuis type strain DSM 21448 (Leibniz-Institute DSMZ, Braunschweig, Germany) and 46 H. parasuis field isolates were used for the present study. 1995. Isolates were cultured in a volume of 5 ml for 48 h at 35°C ± 2°C in ambient air without shaking, and the CFU count per milliliter was determined by culture enumeration every 4 h (up to h 24) and 8 h (up to h 48), respectively. Growth curves were performed in four different broth media (HTM, TMB, VFM, and CAMHB plus 2.5% LHB), as these media have been proven suitable for susceptibility testing of fastidious organisms (7, 10, 11, 21–23). The entire comparison of MICs of 47 isolates and 15 antimicrobial agents fulfilling the inclusion criteria for statistical analysis, independent of MIC50s and MIC90s, showed no significant difference (P = 0.2076) between the two media. Susceptibility testing.For broth microdilution susceptibility testing, customized 50-μl/well microtiter plates (Sensititre, East Grinstead, UK) coated with vacuum-dried antibiotics were used. The saline suspension was diluted 1:200 in broth medium (e.g., CAMHB with 0.0025% NADH and 1% sterile filtered heat-inactivated chicken serum) to yield an inoculum density of approximately 5 × 105 CFU/ml. For information on procedures and interpretation of results, consult listed references or refer to the prepared media Instructions for Use (IFU) for Cat. The CLSI recommend the following cation levels Ca++, 20-25mg/L; Mg++, 10-12.5mg/L. Mueller Hinton Broth contains beef infusion, casamino acids and starch. However, statistical analysis of individual antimicrobial agents showed significant differences of MICs between the two media for the following antimicrobial agents, which were significantly higher in TMB for the antimicrobials colistin (P = 0.0038), gentamicin (P = 0.0006), and neomycin (P < 0.0001) and significantly lower in TMB for doxycycline (P = 0.0010), florfenicol (P = 0.0003), streptomycin (P = 0.0127), and tiamulin (P = 0.0110). When analyzing the data, antimicrobial agents were omitted from statistical analysis when more than 50% of isolates had a MIC at the lowest concentration tested. Test ranges of antimicrobial agents included in this study. 5 HTM was subsequently developed for the testing of fastidious organisms. Barry and Fay. However, MIC endpoints could be determined in VFM only for the type strain. and J.A. Koneman, E.W., et al. The acute form of disease, Glässer's disease, is characterized by clinical signs of polyarthritis, polyserositis, meningitis, and pneumonia (among others) and can lead to sudden death of animals, especially in weaner pigs (2, 3). Soc. The media were compared separately for antibiotic agents using the two-sided one-sample t test for the differences between the two media. Tille, P., et al. INTENDED USE Remel Mueller Hinton Broth w/ Cations is a liquid medium recommended for use in the qualitative procedures for the cultivation of awide variety of microorganisms. Kirby, et al. Preparation of Mueller Hinton Agar (MHA) Suspend 38 gm of the medium in 1000ml of distilled water. The use of both media resulted in reproducible and comparable MICs, with MICs of quality control strains being in the acceptable range for nearly all antimicrobial agents tested. | Ref. Mueller Hinton Broth, not cation-adjusted, is a dehydrated culture medium that is not supplemented with calcium or magnesium ions. Cation-adjusted Mueller Hinton Broth is the medium usually used for dilution antimicrobial susceptibility tests. 413824 - 100 x 90 mm Five out of 21 MIC50s were up to two dilution steps higher when using TMB, while it was seen that one MIC50 was one dilution step lower. Contact us for support › Back to top. Growth curves.To compile growth curves, type strain DSM 21448 of H. parasuis and three field isolates of serovars 5 (2 isolates) and 14 (1 isolate) were used. 9. The reproducibility of MICs obtained in this medium was evaluated and statistically analyzed, considering a model with two different variables (precondition of five identical MICs and MIC mode accepting a deviation of ±1 dilution step, respectively). Autoclave at 121°C for 15 minutes. *Please select more than one item to compare Mueller Hinton Broth is used for the cultivation of a wide variety of fastidious and nonfastidious microorganisms. * Adjusted and/or supplemented as required to meet performance criteria. OADC enrichment is not considered hazardous by the supplier. Standard microbiological supplies and equipment such as autoclaves, incinerators, and incubators, etc., are not provided. Am. Currently, there is no agreed method available for broth microdilution susceptibility testing of Haemophilus parasuis, one of the most important bacterial pathogens in pig production. It may be used for broth dilution antimicrobial susceptibility testing as long as the calcium and magnesium ion concentrations are adjusted according to CLSI standard M7. R38. Conclusion.For broth microdilution susceptibility testing of H. parasuis, supplemented CAMBH and TMB have been shown to be most suitable. The outcome was set to 1 if preconditions were fulfilled according to the variable and 0 otherwise. Mueller-Hinton agar is a microbiological growth medium that is commonly used for antibiotic susceptibility testing. With VFM, visible growth could be detected only for seven isolates, although the H. parasuis type strain and all three field isolates showed a sufficient increase in CFU/ml during growth curve determination. Mueller Hinton Broth. The multifactorial logistic regression analysis with the 11 antibiotics fulfilling statistical requirements revealed that no significant influence of the different incubation times on MICs obtained in both media was observed, either for the evaluation of data by exact MIC agreement (P = 0.5165) or by essential MIC agreement accepting a deviation of ±1 dilution step (P = 0.1913). Industry. The only exceptions for TMB were the combinations A. pleuropneumoniae with gentamicin and A. pleuropneumoniae with the antibiotics gentamicin and penicillin in supplemented CAMHB in all three repetitions. Bauer, A.W., W.M.M. Applications. Subsequently, colony count determinations during culturing of type strain DSM 21448 and three H. parasuis field isolates in supplemented CAMHB were performed, and adequate growth of all isolates could be detected (see Fig. Supplemented CAMHB is recommended for routine diagnostics since it is based on an agreed-upon and validated base medium, which is commercially available. Clinical Microbiology Procedures Handbook, Vol. A list of all formulations tested is given in Table 1. NOTE: We request your email address only to inform the recipient that it was you who recommended this article, and that it is not junk mail. Evaluation was done by taking one model with two variables (precondition of five identical MICs, here referred to as exact MIC agreement, and MIC mode accepting a deviation of ±1 dilution step, referred to as essential MIC agreement, respectively) into consideration. 1 However, this medium is not satisfactory for fastidious organisms such as S. pneumoniae. Heat with frequent agitation and boil for one minute to completely dissolve the medium. As the third H. parasuis field isolate (no. BD BBL™ Mueller Hinton II Broth (Cation-Adjusted) is used for antimicrobial susceptibility testing of microorganisms by broth dilution methods.Dehydrated microbiology culture media cultivate and isolate microorganisms for researching purposes. Store the sealed bottle(s) containing dehydrated culture medium at 2-30ºC. The oleic acid bovine albumin complex is composed of saline with 0.06% (vol/vol) oleic acid and 5% (vol/vol) 0.05 N NaOH, which is finally enriched with 4.75% (vol/vol) bovine serum albumin (7). TMB is a complex medium consisting of 1% (wt/vol) Biosate peptone, 1% (wt/vol) sodium chloride, 0.1% (wt/vol) starch, 0.1% (wt/vol) glucose, and 0.05% (wt/vol) yeast extract, which is supplemented with 0.0025% (vol/vol) NADH, 0.0005% (vol/vol) thiamine HCl, 1% (vol/vol) sterile filtered heat-inactivated chicken serum, and 5% (vol/vol) oleic acid bovine albumin complex. To investigate whether the stability of the MICs differed between the two incubation times, for each combination of isolate, medium, antibiotic agent and incubation time, MIC data received from five measurements were summarized to a dichotomous outcome. Each lot of CRITERION™ Mueller Hinton Broth powder has been tested to determine calcium ion and magnesium ion concentration. Catalogue number: 1214. As a consequence, no validated and standardized method is available (7, 8), and many diagnostic laboratories are currently unable to offer susceptibility testing of this very important pathogen in pig production. Nitrate Broth: some bacteria (e.g., Pseudomonas aeruginosa) have respiratory enzyme systems that can use nitrate as a terminal electron acceptor. CAMHB was used since it is a validated and agreed medium for susceptibility testing with an optimal rate of cations, showing high reproducibility of MIC data and being recommended in CLSI document VET01-A4 for MIC determination of rapidly replicating bacteria. Agar is the solidifying agent. As there are no CLSI-recommended breakpoints for H. parasuis isolates available, a classification of isolates as susceptible or resistant was not possible. Due to the distribution of MICs being skewed to the right and a 2-fold dilution series being used, data were log transformed to the base 2. As antimicrobial agents are used for the treatment of disease, a reliable method for susceptibility testing of the pathogen is essential. However, a few studies investigated the susceptibility status of H. parasuis isolates quantitatively by using media such as veterinary fastidious medium (VFM) or Haemophilus test medium (HTM) for broth microdilution susceptibility testing (7, 9–16). ; 48:330-333. Subsequently, 47 H. parasuis isolates representing 13 serovars were tested with the newly developed medium and TMB. No significant influence on the homogeneity of MICs was seen for the exact (P = 0.5584) and the essential MIC agreement (P = 0.9954) for the antimicrobial agents. Furthermore, due to high losses on pig farms worldwide caused by H. parasuis (20), finding an appropriate and agreed-upon method of susceptibility testing for this important veterinary pathogen is urgently required.

CRITERION™ Mueller Hinton Broth contains the same ingredients as Mueller Hinton Agar, with the exception of the solidifying agent. ISO 16782. The CLSI recommend the following cation levels Ca++, 20-25mg/litre; Mg++, 10-12.5mg/litre. CRITERION™ Mueller Hinton Broth contains the same ingredients as Mueller Hinton Agar, with the exception of the solidifying agent. Because of a simplified implementation in routine diagnostic and a lower chance of interference between medium components and antimicrobial agents, supplemented CAMHB is recommended with an incubation time of 24 h. Haemophilus parasuis is an abundant colonizer of the upper respiratory tract in swine (1). Exp. Mueller-Hinton Broth: culture medium for broth tube antibiotic MIC assay Return to Top of Media List. As pH measurements showed values between pH 7.2 and 7.4, a pH adjustment of the supplemented CAMHB was not necessary. The proposed method enables broth microdilution susceptibility testing of H. parasuis isolates in routine diagnostics and might contribute to establishment of a standardized method for this important veterinary pathogen. At least 15 different H. parasuis serovars have been identified so far, with the most common serovars being 4 and 5 (4, 5). Homogeneity of H. parasuis MICs.To assess the homogeneity of MICs obtained with supplemented CAMHB and TMB with two different incubation times, the H. parasuis type strain and the two field isolates included in the growth curve determinations were used. In brief, isolates were grown on chocolate agar for 24 to 48 h at 35°C ± 2°C in ambient air, colonies were suspended in 0.9% saline, and the suspension was adjusted to an initial concentration of approximately 103 to 104 CFU/ml. Hardy Diagnostics Mueller Hinton Media is recommended for use in the cultivation of a wide variety of microorganisms. Pack size * 500 g. FORMULA. For H. parasuis susceptibility testing, an incubation time of 24 h is recommended. Key Terms: Agar, Colonies, Liquid Media, Nutrient Agar, Nutrient Broth, Petri Dishes, Solid Media . Stability of measurements was analyzed based on this outcome with a multifactorial logistic regression model depending on isolate, medium, antibiotic agent, and incubation time. Ingredients : Gms/Litre: Beef extract: 2.0: Acid hydrolysate of casein: 17.5: Starch: 1.5: Agar: 17.0: Final pH 7.3 +/- 0.1 at 25ºC. The prepared media should appear clear, and very light amber in color; may have slight precipitate. For full text of abbreviations: see SECTION 16. (5), Thymidine in excessive amounts can reverse the inhibitory effects of sulfonamides and trimethoprim.(7). Results from MIC determinations of H. parasuis field isolates.Using both media, supplemented CAMHB and TMB, there was no difficulty in determining visible growth of all 47 H. parasuis isolates in the wells of microtiter plates and reading of MIC endpoints was feasible. Pathol. The product of the reaction is nitrite. Mueller Hinton E agar is a medium for antimicrobial susceptibility testing by diffusion. Homogeneity of MICs obtained with supplemented CAMHB by using two different incubation times, Homogeneity of MICs obtained with TMB by using two different incubation timesa. Data evaluation and statistical analysis. 6. Therefore, a new medium, cation-adjusted Mueller-Hinton broth (CAMHB) plus NADH and sterile filtered heat-inactivated chicken serum, was developed. Beef Extract and Acid Hydrolysate of Casein provide nitrogen, vitamins, carbon, amino acids, sulphur and other essential nutrients. S1 to S5 in the supplemental material). Mueller, J.H. ATCC is a registered trademark of the American Type Culture Collection. SUMMARY AND EXPLANATION This medium was originally formulated by Mueller and Hinton as a proteinfree medium for the purpose of isolating pathogenic - Neisseria. One important factor is the applicability of QC strains and their MICs within a specified range. CAMHB was taken as a basis since it is the CLSI-approved medium of choice for susceptibility testing of commonly isolated pathogens. Statistical analyses were carried out using SAS software, version 9.3 (SAS Institute, Cary, NC) (25). Testing included 21 antimicrobial agents and antibiotic combinations (Table 5), four of which are currently not licensed for food-producing animals and were included for comparison reasons (cefotaxime, ciprofloxacin, imipenem, and nalidixic acid). Mueller Hinton Agar is recommended for disk diffusion sensitivity testing of non-fastidious organisms. Am. Thank you for sharing this Journal of Clinical Microbiology article. Analysenzertifikat suchen. Additionally, there are issues about batch-to-batch reproducibility and a low content of inhibitors that affect antimicrobial agents that still have to be addressed.

Antimicrobial susceptibility testing Clinical. As the medium had no significant influence on the homogeneity of the MICs and although TMB seems to support the growth of H. parasuis isolates slightly better, CAMHB provides the advantage of a validated basic broth medium (17). In Murray, P.R., et al. Surprisingly, visible growth in microtiter plate wells was detected in only 25% of the tested H. parasuis field isolates cultured in VFM. BD Mueller Hinton II Agar wird mit einem niedrigen Gehalt an Thymin und Thymidin ... z. The growth curves from two independent experiments revealed that all isolates showed almost consistent growth in VFM and TMB. Supplements were added to CAMHB aseptically after autoclaving, and concentrations of supplements were equal to concentrations used in TMB. Comparative analysis of MICs.For simplified interpretability of MICs, an incubation time of 24 h was chosen for comparative analysis. - Hier erfahren Sie mehr - Mehr aus: Bio-, Organische Chemikalien *Packung * Pflichtfelder. 4. In this study, colony count determinations during culturing in four different media detected growth of H. parasuis field isolates in VFM and TMB, whereas only growth of type strain DSM 21448 could be detected in HTM and CAMHB plus 2.5% LHB. … Wood, G.L. These ingredients are selected for low thymine and thymidine content as determined by MIC values with Enterococcus faecalisand sulfamethoxazole-trimethoprim (SXT). However, the broadest distribution of MICs was found for the antibiotic combination trimethoprim-sulfamethoxazole. Differences in MICs depending on incubation time were investigated with an analysis of variance (ANOVA) model, modeling the log-transformed MICs depending on the four factors. Preparation of this medium is less challenging and sensitive and could be used in routine diagnostic laboratories. Results of these experiments showed that supplementation of sterile filtered inactivated chicken serum or O-A complex is necessary to obtain visible growth of H. parasuis isolates in CAMHB (Table 1). Supplementation of CAMHB and determination of visible growth of 15 H. parasuis isolates. to 29 CFR 1910.1200 App D Muller Hinton II Cation-Adjusted Broth Version number: GHS 2.0 Replaces version of: 2016-02-18 (M5860 1) Revision: 2018-07-03 United States: en Page: 1 / 9. Manual of Clinical Microbiology, 7th ed. In a recent study, VFM was reported to be unsuitable for broth microdilution susceptibility testing of Australian H. parasuis isolates, and TMB was proposed (7). Results from the repeated tests are shown in Tables 2 and 3. Mueller Hinton Broth is recommended for preparing suspensions of microorganisms for disk diffusion sensitivity testing. VFM is recommended in CLSI standard VET01-A4 for susceptibility testing of Actinobacillus pleuropneumoniae and Histophilus somni , while HTM and cation-adjusted Mueller-Hinton broth (CAMHB) supplemented with 2.5% to 5% lysed horse blood (LHB) are CLSI-approved broth media for the testing of fastidious organisms, with HTM being recommended for Haemophilus influenzae and … This medium is recommended for antimicrobial susceptibility testing of aerobic organisms by the broth dilution method as well as for preparing dilutions of organisms to be used in the Kirby-Bauer disk diffusion procedure. B. BD TrypticaseTM Soy Broth (Casein­Soja-Pepton-Bouillon) oder Mueller-Hinton-II-Bouillon (Kationen-adjustiert) für die Zubereitung eines Standardinokulums und sterile Bouillon oder Salzlösung für die Verdünnung des Inokulums.7 Gemäß EUCAST: 0,9%ige Kochsalzlösung (Mengen von 5 mL) zur … Due to the explorative nature of the experiments, no multiple adjustments were performed and comparison-wise P values were reported. 1. The main component, Mueller Hinton Agar, was originally prepared as a solid media used to test the antimicrobial susceptibility testing of common, non-fastidious, rapidly growing organisms. ASM journals are the most prominent publications in the field, delivering up-to-date and authoritative coverage of both basic and clinical microbiology. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. For supplementation of CAMHB, the medium was first tested with all TMB supplements, and then one supplement at a time was removed. However, the majority of isolates proved to have very low MIC50s and MIC90s (equal to or below 0.5 μg/ml) for all β-lactam antimicrobials, and only a couple of isolates showed elevated MICs in comparison to the majority of isolates (Table 4). The amount of growth in the wells was comparable to the amount of growth in microtiter panels with TMB medium (Table 1). CM0405 Date of issue - 09/10/2008. Some strains may be encountered that fail to grow or grow poorly in this broth. Broth dilution antimicrobial susceptibility testing can be performed using Mueller Hinton Broth. It typically contains: 2.0 g beef extract; 17.5 g casein hydrolysate; 1.5 g starch; 17.0 g agar; 1 liter of distilled water. Isolates were cultured on chocolate agar with 10% defibrinated horse blood in ambient air at an incubation temperature of 35°C ± 2°C for 24 to 48 h. To confirm that the field isolates were H. parasuis, a PCR assay amplifying an 821-bp internal fragment of the 16S small subunit rRNA gene was used as described earlier (20). To further reduce the number of supplements, it was evaluated if growth of the H. parasuis isolates varied when only two supplements were added to CAMHB. The isolates originated from diseased pigs and were collected at pig farms from different geographic regions in Germany between 2011 and 2013. (1), Mueller Hinton Broth should be inoculated within 15 minutes after preparing the inoculum suspension.(1). This initial media, however, was not suitable for fastidious organisms such as streptococci, gonococci, and Haemophilus species. For this purpose, which of the supplements of TMB were essential to provide sufficient growth of preferably all H. parasuis isolates and serovars was evaluated. Mueller Hinton Broth is recommended for the cultivation of microorganisms, and for making dilutions of organisms to be used in the Kirby-Bauer disk diffusion procedure. Clinical Laboratory Standards Institute (CLSI - formerly NCCLS), Villanova, PA. 8. We have no conflicts of interest to declare. pH, cation concentration, and thymidine contents) are well maintained.. Mueller Hinton agar (MHA) can be purchased from commercial suppliers or can also be prepared from the dehydrated medium. Fast-dissolving powders come premixed for quick preparation using neutral liquids. Lysed horse blood or thymidine phosphorylase may be added to the broth to improve the MIC endpoints of sulphonamides and trimethoprim 3. Considering the results from supplemented CAMHB, a bimodal distribution of MICs was detected for the antimicrobial agents ampicillin, ciprofloxacin, colistin, doxycycline, enrofloxacin, nalidixic acid, neomycin, penicillin, streptomycin, tetracycline, and tilmicosin, whereas a unimodal distribution was determined for the remaining antibiotics tested. Growth of H. parasuis in broth media.To determine the adequacy of the broth media for susceptibility testing, type strain DSM 21448 and three H. parasuis field isolates of serovars 5 (two isolates) and 14 (one isolate) were chosen. It is recommended that procedures are accurately followed to ensure reliable results. Enter multiple addresses on separate lines or separate them with commas. Color Atlas and Textbook of Diagnostic Microbiology, J.B. Lippincott Company, Philadelphia, PA. 7. The necessity of the supplements was tested against a set of 15 H. parasuis isolates in 96-well microtiter plates, and visible growth in the wells was determined (Table 1).
