Neisseria Gonorrhoeae On Blood Agar

Neisseria Gonorrhoeae On Blood Agar. Cultural and biochemical characteristics for identification of Neisseria gonorrhoeae Gonorrhoeae is a fragile organism with strict environmental and nutritional requirements At pH 7074 and at a temperature of 3536 °C growth occurs best It is an aerobe meaning it needs oxygen to grow however it can grow in anaerobic conditions as well.

Colony characteristics of Neisseria gonorrhoeae on 5% sheep blood agar (BAP) are as follows Small Round grey white opaque as shown above picture They are easily emulsifiable It produces four types of colonies and they are T1 T2 T3 and T4 T1 and T2 Small brown colonies and possess pili They are autoagglutinable and virulent strains.

Does Neisseria gonorrhoeae grow on nutrient agar? Neisseria are fastidious organisms that require nutrient supplementation to grow in laboratory cultures Specifically they grow on chocolate agar which is an enriched growth medium containing red blood cells that have been lysed providing growth factors like NAD and hemin.

The laboratory diagnosis of Neisseria gonorrhoeae

Traditional approaches to the diagnosis of gonorrhea have used direct smear or culture Culture for Neisseria gonorrhoeae is typically performed on media such as chocolate (cooked sheep’s blood) agar ThayerMartin or GC medium incubated in a 5% CO 2 atmosphere.
