Enterobacteriaceae Family (CRE), Is of Utmost Importance for the Enterobacteriaceae Management of Infected Or Colonized Patients

Methods: Three carbapenems; meropenem, imipenem and ertapenem, with two different concentrations (0.5 mg/ml and 1.0 mg/ml), were impregnated in Mac- Conkey agar. The carbapenem impregnated MacConkey agar plates; ([Mac-Mem], [Mac-Imp] and [Mac-Ert]), were then evaluated for the detection of carbapenem resistant Gram-negative bacteria in particular the blaKPC producing Enterobacteria- ceae. The Limit of Detection (LOD) of the plates was determined in triplicate after serial logarithmic dilution of the bacterial strains in saline. This was followed by inoculating the plates and counting the colonies that grew after 24 hours of incu- bation. The specificity and the shelf-life of the plates were determined by testing the plates with six Extended Spectrum β-lactamases (ESBL) producing members of the Enterobacteriaceae family and one genus with the blaAmpC phenotype. -
Chocolate Agar Plate MP103 Intended Use for Isolation of Neisseria Gonorrhoeae from Chronic and Acute Gonococcal Infections
Chocolate Agar Plate MP103 Intended use For isolation of Neisseria gonorrhoeae from chronic and acute gonococcal infections. Composition** Ingredients Gms / Litre Proteose peptone 20.000 Dextrose 0.500 Sodium chloride 5.000 Disodium phosphate 5.000 Agar 15.000 After sterilization Sterile Lysed blood (at 80°C) 50.000 Vitamino Growth Supplement (FD025) 2 vials Final pH ( at 25°C) 7.3±0.2 **Formula adjusted, standardized to suit performance parameters Directions Either streak, inoculate or surface spread the test inoculum (50-100 CFU) aseptically on the plate. Principle And Interpretation Neisseria gonorrhoeae is a gram-negative bacteria and the causative agent of gonorrhea, however it is also occasionally found in the throat. The cultivation medium for gonococci should ideally be a rich nutrients base with blood, either partially lysed or completely lysed. The diagnosis and control of gonorrhea have been greatly facilitated by improved laboratory methods for detecting, isolating and studying N. gonorrhoeae. Chocolate Agar Base, with the addition of supplements, gives excellent growth of the gonococcus without overgrowth by contaminating organisms. G.C. Agar (M434) can also be used in place of Chocolate Agar Base, which gives slightly better results than Chocolate Agar (4). The diagnosis and control of gonorrhea have been greatly facilitated by improved laboratory methods for detecting, isolating and studying N. gonorrhoea. Interest in the cultural procedure for the diagnosis of gonococcal infection was stimulated by Ruys and Jens (9), Mcleod and co-workers (8), Thompson (7), Leahy and Carpenter (1), Carpenter, Leahy and Wilson (2) and Carpenter (10), who clearly demonstrated the superiority of this method over the microscopic technique. -

However, this species may have a disruptive role on native communities in areas where it has recently arrived due to predation and the potential introduction of novel pathogens. We report reference information on the cultivable gut microbial landscape of widely distributed Egyptian mongoose populations (Herpestes ichneumon, n = 53) and related antimicrobial tolerance across environmental gradients. -

Macconkey Agar, CS, Product Information
MacCONKEY AGAR, CS (7391) Intended Use MacConkey Agar, CS is used for the isolation and differentiation of Gram-negative enteric bacilli from specimens containing swarming strains of Proteus spp. in a laboratory setting. MacConkey Agar, CS is not intended for use in the diagnosis of disease or other conditions in humans Product Summary and Explanation MacConkey Agar is based on the bile salt-neutral red-lactose agar of MacConkey.1 The original MacConkey medium was used to differentiate strains of Salmonella typhosa from members of the coliform group. Formula modifications improved growth of Shigella and Salmonella strains. These modifications include the addition of 0.5% sodium chloride, decreased agar content, altered bile salts, and neutral red concentrations. The formula modifications improved differential reactions between enteric pathogens and coliforms. MacConkey Agar, CS (“Controlled Swarming”) contains carefully selected raw materials to reduce swarming of Proteus spp., which could cause difficulty in isolating and enumerating other Gram-negative bacilli. Principles of the Procedure Enzymatic Digest of Gelatin, Enzymatic Digest of Casein, and Enzymatic Digest of Animal Tissue are the nitrogen and vitamin sources in MacConkey Agar, CS. Lactose is the fermentable carbohydrate. During Lactose fermentation a local pH drop around the colony causes a color change in the pH indicator, Neutral Red, and bile precipitation. Bile Salts and Crystal Violet are the selective agents, inhibiting Gram-positive cocci and allowing Gram-negative organisms to grow. Sodium Chloride maintains the osmotic environment. Agar is the solidifying agent.

CO 2 favors primary isolation. The medium is best for organisms which require X and V Factor. HISTORY/SUMMARY: Interest in the cultural procedure for the diagnosis of gonococcal infections was stimulated by Ruys and Hens McLeod et al 2, Leahy and Carpenter, Leahy and Wilson 5 and Carpenter 6 who clearly demonstrated the superiority of this method over the microscopic technique. Further studies in cooperation with Carpenter, and McLeod 7 and Herrold resulted in the development of Chocolate Agar prepared with Proteose No. 3 Agar and Hemoglobin, which proved to be satisfactory for isolating the organism from all types of gonococcal infections. Chapin and Doern found that in only 6 of 17 cases was Haemophilus influenzae recovered from sputum specimens cultured by using conventional techniques including enriched chocolate agar (CHOC) media, despite the fact that gram stained smears of sputum specimens often revealed a predominance of pleomorphic gram- negative bacilli. Observations such as these have lead to the development of selective media which inhibit upper respiratory tract microbial flora while permitting growth of Haemophilus influenzae . Approaches utilized most frequently incorporate bacitracin into various enriched basal media ( 11, 12, 13, 14 ). -
Cetrimide Agar Base M024
Cetrimide Agar Base M024 Intended use Cetrimide Agar Base is used for the selective isolation of Pseudomonas aeruginosa from clinical specimens. Composition** Ingredients Gms / Litre Gelatin peptone 20.000 Magnesium chloride 1.400 Potassium sulphate 10.000 Cetrimide 0.300 Agar 15.000 Final pH ( at 25°C) 7.2±0.2 **Formula adjusted, standardized to suit performance parameters Directions Suspend 46.7 grams in 1000 ml distilled water containing 10 ml glycerol. Heat, to boiling, to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. Cool to 45-50°C. If desired, rehydrated contents of 1 vial of Nalidixic Selective Supplement (FD130) may be added aseptically to 1000 ml medium. Mix well and pour into sterile Petri plates. Principle And Interpretation Pseudomonas aeruginosa grows well on all normal laboratory media but specific isolation of the organism, from environmental sites or from human, animal or plant sources, is best carried out on a medium, which contains a selective agent and also constituents to enhance pigment production. Most selective media depend upon the intrinsic resistance of the species to various antibacterial agents. Cetrimide inhibits the growth of many microorganisms whilst allowing Pseudomonas aeruginosa to develop typical colonies. Cetrimide is a quaternary ammonium salt, which acts as a cationic detergent that reduces surface tension in the point of contact and has precipitant, complexing and denaturing effects on bacterial membrane proteins. It exhibits inhibitory actions on a wide variety of microorganisms including Pseudomonas species other than Pseudomonas aeruginosa. King et al developed Medium A for the enhancement of pyocyanin production by Pseudomonas (1). -

Wastewater treatment plants (WWTPs) are thought to be “hotspots” for antibiotic resistance dissemination. The conditions of WWTPs, in conjunction with the persistence of commonly used antibiotics, may favor the selection and transfer of resistance genes among bacterial populations. WWTPs provide an important ecological niche to examine the spread of antibiotic resistance. We used heterotrophic plate count methods to identify Citation: Sorgen, A.; Johnson, J.; phenotypically resistant cultivable portions of these bacterial communities and characterized the Lambirth, K.; Clinton, -
