Culture Media For Gonococcus

Transportation of material for the culture of the gonococcus.

Until the beginning of World War lI the culture method was not extensively used in the diagnosis of gonorrhoea; diagnosis by culture was made only where laboratory facilities were available close to the clinics. The rapidly increasing incidence of gonorrhoea-especially among soldiers-made it desirable to obtain better diagnosis and control of the disease, and it became necessary to provide clin...

Culture Media for Brucella.

Trypsin digesting medium added with horse plasma for the culture of the gonococcus.

To identify Neisseria-like colonies suspected to be gonococci, it is necessary to use the " oxydase" reaction of Gordon and McLeod (1928); colonies sprayed with a 1 per cent. solution of dimethyl paraphenylene hydrochloride turn pink immediately on contact with the oxidizing fluid, and then black in 2 to 3 minutes. If blood media are used, the " oxydase" reaction is not readily visible owing to...

Optimization of culture media for lipid production by Nannochloropsis oculata for Biodiesel production

Background: This study quantified the effect of four popular culture media in a biodiesel production study on the qualitative and quantitative lipid content, dry biomass, and lipid productivity of Nannochloropsis oculata. Methods: Culture of microalgae was done separately in Walne, F/2, Sato, and TMRL media. In the logarithmic and stationary growth phases, biomass production and lipid accumulat...

Studies on Gonococcus Infection

The four colony types of several different strains of gonococci were isolated by selective transfers on agar. These colony variants differed in the degree of autoagglutination which occurred when they were grown in fluid medium. It was found that this clumping behavior was related to the colonial type, with type 2 isolates exhibiting the greatest autoagglutination followed by types 3, 1, and 4....
