- Principle And Interpretation Streptococcus agalactiae is a gram-positive Streptococcus characterized by the presence of group B Lancefield antigen.S. agalactiae exhibits beta haemolysic reaction. On Blood agar plate, it forms zones of haemolysis that are slightly bigger thanthe size of colonies formed.Group B streptococci hydrolyze sodium hippurate and give a positive response in the CAMP test.S. agalactiae is also sensitive to bile and will lyse in its presence.lease refer disclaimer Overleaf. Streptococcus Agalactiae Selective Agar Base M1257 Streptococcus Agalactiae Selective Agar is recommended for selective isolation of Streptococcus agalactiae from dairyproducts.

Sabouraud Dextrose Agar (SDA): Principle, composition, uses and colony morphology 4.28 / 5  ( 25 ) Sabouraud Dextrose Agar (SDA) is a selective medium primarily used for the isolation of dermatophytes, other fungi and yeasts but can also grow filamentous bacteria such as Nocardia. The acidic pH of this medium (pH about 5.0) inhibits the growth of bacteria but permits the growth of yeasts and most filamentous fungi.

Agar plate Chocolate agar is a type of blood agar plate in which the blood cells have been lysed by heating the cells to 56 °C. It is used for growing fastidious respiratory bacteria, such as Haemophilus influenzae. No chocolate is actually contained in the plate; it is named for the coloration only. Horse blood agar

- Cool to about 50°C. Mix and pour intosterile Petri plates. Principle And Interpretation SS Agar medium is recommended as differential and selective medium for the isolation of Salmonella and Shigella speciesfrom pathological specimens (1) and suspected foodstuffs (2, 3, 4, 5) and for microbial limit test (6).higella species also grow as colourless colonies which do not produce H2S.It is recommended to inoculate plates of less inhibitory media parallel to SS Agar, such as Hektoen Enteric Agar (M467) orDeoxycholate Citrate Agar (M065) for easier isolation of Shigella species (7).

TRYPTIC SOY AGAR (TSA) Method of Use: Plates should be warmed to room temperature and the agar surface should be dry prior to inoculating. Inoculate and streak the specimen as soon as possible after collection. If the specimen to be cultured is on a swab, roll the swab over a small area of the agar surface. Streak for isolation with a sterile loop. Incubate plates aerobically at 35-37°C for 18-24 hours (some organisms may take longer than 24 hours for visible growth to appear). Examine for colonial morphology.

- In general agar media supports the growth of bacteria (cells without a nucleus) and some species of yeasts and molds (things with a nucleus that can make fuzzy bread). You can't culture viruses or most parasites on Petrie plates. First you should find out the kinds of agar plate. If you used blood agar plates - nutrient agar with 5-10% sheep's blood or horse blood, you can determine if the colonies hemolyze the red cells in the media. Hemolysis is the process of breaking apart red blood cells, and only certain bacteria species do it.

Examples of Antibiotic Sensitivity Testing Methods On this agar plate, a bacterial isolate is tested for resistance to each of twelve different antibiotics. The clear zones around each disc are the zones of inhibition that indicate the extent of the test organism’s inability to survive in the presence of the test antibiotic. (A)The disk shows a large zone of inhibition; whereas (B) shows no zone of inhibition, indicating resistance of the isolate to the test antibiotic

- Refer to Aseptic techniques before starting this or any other microbiology practical work. You can make streak plates of bacteria or yeasts. A streak plate involves the progressive dilution of an inoculum of bacteria or yeast over the surface of solidified agar medium in a Petri dish. The result is that some of the colonies on the plate grow well separated from each other.

- Confidence votes 195. The purpose of the spread-plate technique is to grow and isolate colonies of bacteria. A sample of bacteria is transferred to the agar plate, an environment that provides nourishment for the bacteria to grow.

- Blood agar plates are routinely used in the clinic to test for pathenogenic bacteria in throat swabs. These throat pathogens are often Gram positive cocci that may be hemolytic, producing exotoxins called hemolysins that destroy blood cells.

Streptococcus agalactiae Group B streptococci. Colonies of Streptococcus agalactiae cultivated on Columbia agar with 5% sheep blood. Cultivation 24 hours in an aerobic atmosphere enriched with 5% carbon dioxide. Colonies are surroundend by a zone of beta-hemolysis.Streptococcus agalactiae is a member of the gastrointestinal normal flora in some humans and can spread to secondary sites-including the vagina in 10 30% of women.his is of clinical importance: S. agalactiae can be transferred to a neonate passing through the birth canal and can cause serious group B streptococcal infection. In the western world, S. agalactiae is the major cause of bacterial septicemia of the newborn, which can lead to death or long-term sequelae.

Principle: It is tedious to isolate a particular type of bacteria from a clinical sample. Streak plate technique is used to grow bacteria on a growth media surface so that individual bacterial colonies are isolated and sampled. Isolated colonies indicate a clone of cells, being derived from a single precursor cell.

Mycology Routine fungal cultures: Using special media, including chromogenic agars for yeast identification and our in-house developed potato agar, we can recover most pathogenic fungi from clinical specimens. Moulds are identified based on visual morphology, growth temperature, enzymatic capabilities, and other characteristics.

CAS agar diffusion assay for the measurement of siderophores in biological fluids â CAS plate assay has been used mainly for screening siderophore production by various wild type or mutant strains. However, it is difficult to grow fastidious microorganisms on the CAS agar plate and some ingredients of the CAS agar have innate antibacterial activity.

- when growing on agar plates. Two different types of agar plate isolation techniques will be used---streak and pour. Each method has advantages and disadvantages, and particular uses. The same mixed culture will be used for both methods. Another technique, called the spread plate, is used commonly for counts, as is the pour plate technique. It uses pre-made

- Salmonella-Shigella plates. Salmonella-Shigella (SS) plates are used to detect bacterial contamination on raw meat. Salmonella-Shigella agar plates contain lactose, bile salts, ferric citrate, and neutral red.The bile salts select for Gram-negative bacteria.oliform bacteria such as E. coli will ferment the lactose in the media, resulting in bacterial growth with a pink color. (They do not produce any hydrogen sulfide.) Members of the genus Salmonella will not ferment lactose, but do product hydrogen sulfide gas.
