  • Cultures Producted by: Abbas Morovvati
  • Blood agar (BA)• Use : For the isolation, cultivation and detection of hemolytic activity of streptococci, pneumococci and other particular fastidious microorganisms.• Control organisms : Streptococcus pneumoniae : Good growth, Alpha - hemolysis Streptococcus pyogenes : Good growth, Beta-hemolysis• Incubate: aerobic 35 C, 24 hrs.• Shelf life : 4 weeks• Price (Baht) : 12 (return plate) , 15 (disposable plate)
  • Chocolate agar (CA)• Use : For the isolation and cultivation of a variety of fastidious microorganism.• Control organisms : Hemophilus influenzae and Neisseria gonorrhoeae : Good growth• Incubate : CO2 ,35 C ,24 hrs.• Shelf life : 4 weeks• Price (Baht) : 12 (return plate) , 15 (disposable plate)
  • MacConkey agar (MC)• Use : For the selective isolation, cultivation and differentiation of coliformsand enteric pathogens based on the ability to ferment lactose. Lactose–fermening organisms appear as red to pink colonies. Lactose- nonfermenting organisms appear as colorless or transparent colonies• Control organisms : Escherichia coli : Pink colonies (lactose fermentation) Proteus mirabilis : Colorless colonies ,no spreading Enterococcus sp. : No growth• Incubate : Aerobic, 35 C, 24 hrs.• Shelf life : 4 weeks• Price (Baht) : 12 (return plate) , 15 (disposable plate)
  • Mueller-Hinton agar (MHA)• Use : For antimicrobial susceptibility testing of a variety of nonfastidious, rapidly-growing microorganisms.• Control organisms : Escherichia coli ATCC25922 , Staphylococcus aureus ATCC 25923, and Pseudomonas aeruginosa ATCC 27853 : Growth ,Inhibition Zone followed Standard interpretative• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 4 weeks• Price (Baht) : 12 (return plate) , 15 (disposable plate)
  • Salmonella-Shigella agar (SS)• Use : For the selective isolation and differentiation of pathogenic enteric bacilli, especially those belonging to the genus Salmonella. This media is not recommended for the primary isolation of Shigella species. Lactose- fermenting bacteria such as Escherichia coli or Klebsiella pneumoniae appear as small pink or red colonies. Lactose-nonfermenting bacteria such as Salmonella species, Proteus species and Shigella species appear as colorless colonies. Production of H2S by Salmonella species turns the center the colonies black.• Control organisms : Salmonella typhi : Colorless colonies, black centers.• Escherichia coli : Pink colonies• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 4 weeks• Price (Baht) : 12 (return plate) , 15 (disposable plate)
  • Eosin Methylene Blue Agar (EMB)• Use : For the isolation, cultivation and differentiation of Gram- negative enteric bacteria based on lactose fermentation. Bacteria that ferment lactose, especially the coliform bacterium Escherichia coli, Appear as colonies with green metallic sheen or blue–black to brown color. Bacteria that do not ferment lactose appear as colorless or transparent light purple colonies• Control organisms : Escherichia coli : Good growth, green metallic sheen. Klebsiella pneumoniae : Good growth, purple colonies, no sheen. Shigella flexneri : Good growth, transparent colonies (lactose negative)• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 4 weeks• Price (Baht) : 12 (return plate) , 15 (disposable plate)
  • Thiosulfate Citrate Bile Salt Sucroseagar (TCBS)• Use : For the selective isolation of Vibrio cholerae and Vibrio parahaemolyticus from a variety of clinical specimens and in epidemiological investigations.• Control organisms : Vibrio cholerae : Growth (yellow colonies) Vibrio parahaemolyticus : Growth (green colonies) Staphylococcus aureus : No growth• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 4 weeks• Price (Baht) : 15 (return plate) , 18 (disposable plate)
  • Sabouraud Dextrose Agar (SDA)• Use : For the cultivation of pathogenic and nonpathogenic fungi, especially dermatophytes. The medium may be made more selective for fungi by the addition of specific antibiotics such as chloramphenicol. For the cultivation of yeast and filamentous fungi.• Control organisms : Aspergillus flavus, Candida albicans : Growth Streptococcus pneumoniae : No growth• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 4 weeks• Price (Baht) : 15 (return plate) , 18 (disposable plate)
  • Trypticase soy broth• Use : For the cultivation of a wide variety of fastidious and nonfastidious microorganisms from blood specimen and in epidemiological investigations. Also used for rapid estimation of the bacteriological quality of water.• Control organisms : Staphylococcus aureus : Good growth Uninoculated tube : No growth and clear• Incubate : 5% CO2, 35 C , 24 hrs• Shelf life : 8 weeks• Price (Baht) : 10 for 45 ml of TSB (return bottle) , 8 for 27 ml of TSB (return bottle)
  • Triple Sugar Iron agar (TSI slant)• Use : For the differentiation of members of the Enterobacteriaceae base on their fermentation of lactose, sucrose and glucose and the production of H2S.• Control organisms : Escherichia coli : A/A (G) Shigella flexneri : K/A Proteus vugaris : K/A, H2S Pseudomonas aeruginosa : K/N• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 8 weeks• Price (Baht) : 5 (return tube)
  • Motility Indole Lysine Medium (MIL)• Use : For the cultivation and differentiation of members of the Enterobacteriaceae on the basis of motility, lysine decarboxylase activity, lysine deaminase activity and indole production.• Control organisms : Proteus vulgaris : Motile / Indole/ LDC/ LDM ; +/+/-/+ Klebseilla pneumoniae : Motile / Indole/ LDC/ LDM ; -/-/+/-• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 8 weeks• Price (Baht) : 5 (return tube)
  • Christensen Urea Agar• Use : For the differentiation of a variety of microorganisms, especially members of the Enterobacteriaceae , aerobic actinomycetes, streptococci and nonfermenting Gram-negative bacteria, on the basis of urease production.• Control organisms : Proteus mirabilis : Pink throughout (positive) Klebsiella pneumoniae : Pink slant (partial positive) Escherichia coli : Yellow (negative)• Incubate : Aerobic 35 C, 24 hrs• Shelf life : 8 weeks• Price (Baht) : 5 (return tube)
