Cryptococcus neoformans is an encapsulated yeast responsible for severe meningoencephalitis. The importance of epidemiological studies on cryptococcosis has increased since the beginning of the AIDS epidemic. C. neoformans exists in two varieties containing four serotypes, C. neoformans var. neoformans (serotypes A and D) and C. neoformans var. gattii (serotypes B and C). Locally C. neoformans var. neoformans has been associated with pigeon feces during those months having an average temperature of 64.2°F j(17.8°C) and above. Clinical and environmental isolates of C. neoformans obtained from regional hospitals and environmental samplings, respectively, have been grouped into their variety status utilizing canavanine-glycine-bromthymol blue …

The LD50 of Vibrio parahaemolyticus ATCC 17803 for 13- to 18-g male mice, strain ICR, as determined by the 50% endpoint method, was found to be an estimated 7 x 107 CFU, when administered intraperitoneally in 0.5 ml of 24-h broth culture, O. D. 0.5 at 650 nm, diluted to 10-0.72.
The elicitation of protective antibody by this bacterium in male New Zealand White rabbits was demonstrated by testing control, baseline, and hyperimmune rabbit sera for their protective effect against 2 LD50 of the bacterium administered intraperitoneally in 13- to 18-g male mice, strain ICR. …
