| biochemical serogrouping of clinical isolates of cryptococcus neoformans. | three hundred twenty-three clinical isolates of cryptococcus neoformans of diverse geographic origins were biochemically serogrouped using glycine-cycloheximide-phenol red agar (gcp), the same medium less cycloheximide (gop), and glycine-l-canavanine bromothymol blue agar (cgb). twenty isolates gave positive reactions on all three media typical of the b and c serotypes. three were from the peoples' republic of china; three each were from michigan (two patients) and louisiana; two each were from ... | 1987 | 3545655 |
| a one year study on the viability of cryptococcus neoformans in nature. | using four different assat procedures we found a 50 to 86% decrease in viability of cryptococcus neoformans over a one year period after two towers in the oklahoma city area were modified to exclude pigeons and weather elements, especially rain. in homogeneous pigeon dropping samples a sharp decrease in viability occurred after 7 to 9 months of storage. the decrease occurred in pigeon dropping samples maintained at the natural sites and at ambient temperature in the laboratory in the laboratory ... | 1982 | 7070480 |
| cryptococcus neoformans serotype groups encountered in oklahoma. | eighty clinical and 28 soil isolates of c. neoformans obtained in oklahoma were separated into a-d and b-c serotype groups utilizing creatinine-dextrose agar with bromthymol blue. previously, serotype b-c clinical isolates have been frequent only in patients from southern california where as many as 50% of the isolates are of this type. in contrast, in patients from the rest of the united states the b-c frequency has been only 6%. of the 80 c. neoformans isolates from oklahoma patients, 12 (15%) ... | 1980 | 6994491 |
| serologic grouping and sexual compatibility of airborne cryptococcus neoformans. | through the use of anderson air samples, 214 isolates of cryptococcus neoformans were cultured from the air in a vacant tower in a large complex of buildings in oklahoma city. the tower contained hundreds of pigeons, a massive amount of droppings, nests with eggs and young, dying and dead pigeons. all isolates were serotype a-d and self-sterile for the production of basidiospores. among these 193 were of the "alpha" mating type, producing basidiospores when paired with "alpha" mating type. no is ... | 1982 | 6755259 |
