词汇 | oocyst |
释义 | BETA Examples of oocystoocyst isn’t in the Cambridge Dictionary yet. You can help! A study of the osmotic relationships between the sporocyst, oocyst and intestinal fluids could be very relevant to the mechanisms of sporozoite liberation. Oocyst shedding by dogs under natural conditions has never been reported. All induced samples were collected within a 3-h badger processing period to limit circadian variations in oocyst output. However, if rates of cell division are unequal, even by a small degree, some meiotic products will be poorly represented in the oocyst. By contrast, the poorly infective immature oocyst sporozoite always triggered the respiratory burst. Only when the oocyst is ingested and passes through the mammalian gut does destabilization of the wall occur with the opening of the suture. Alternatively, the cyclospora oocyst extraction method available may not have worked as well for green leafy vegetables as compared to raspberries. This is unfortunate since the oocyst is basically a dormant stage, and the activities of many enzymes of interest would be expected to be low. The outer layer of the oocyst wall consisted of an osmiophilic layer, 0-08 thick, with a loose granular coat. Just how does the oocyst keep alive during a prolonged period of dormancy? A dose-dependent decrease in oocyst numbers was seen with oryzalin at up to 30 mg\\kg at which time the inhibition reached a plateau. Although so resistant to chemical attack, the oocyst wall does appear susceptible to mechanical forces. The transient diploid stage (the ookinete) attaches to the mosquito midgut wall where it develops into an oocyst. The structure of the oocyst wall was examined by crushing the oocysts with pressure on the cover-slip. Infections derived from 1 oocyst per rodent were performed to exclude a possible co-occurrence of more than 1 eimerian species. The oocyst morphology is considered to be the most important morphological criterion in the eimerian taxonomy. In this study parasite abundances were measured using fecal egg/oocyst counts and are reported as eggs/oocysts per gram feces (epg/opg). For the parasitologist it is clear that oocyst counts made at intervals of more than 3 days could miss valuable information. There was no consistent relationship between diarrhoea and oocyst output. |
