Studies of a glycoprotein in the oocysts of Eimeria tenella.
A glycoprotein unique to the cytoplasm of the unsporulated oocyst of Eimeria tenella has been purified and partially characterized. The protein has a molecular weight of 30,000, of which approximately 40% is carbohydrate. The carbohydrate portion of the molecule consists of glucose, galactose, mannose, xylose, glucosamine, and galactosamine, with no detectable sialic acid. The protein portion c...
متن کاملIncrease in size of Eimeria separata oocysts during patency.
Examinations of 18 consecutive fecal samples collected at 6-hr intervals from infected rats showed that oocysts increased in length and width by approximately 40% from the beginning to the end of the patent period. Unsporulated oocysts were first observed in the 3rd fecal collection, 84 to 90 hr postinoculation (PI) and 100 of these measured 9.9 to 14.3 by 8.8 to 12.1 u (mean 11.7 by 10.1). Pat...
متن کاملMetam sodium reduces viability and infectivity of Eimeria oocysts.
Metam sodium (MS, sodium N-methyldithiocarbamate) is a widely used soil pesticide. Fumigation or chemical sterilization of poultry litter containing infectious oocysts could be an effective strategy to block the transmission of avian coccidia. In the current study, the effect of MS on the viability and infectivity of ocysts was investigated. The development of isolated, unsporulated oocysts of ...
متن کاملIdentification of Cryptosporidium spp. oocysts in fecal smears stained with Heidenhain's iron hematoxylin.
There is no paucity of methods for diagnosing Cryptosporidium spp. infection. The merits of immunoassays notwithstanding, microscopic identification of Cryptosporidium spp. oocysts in fecal samples remains an important diagnostic procedure. It owes the persistence of its use to such characteristics as dispensing with expensive equipment and kits, requiring only basic laboratory facilities, and ...
متن کاملIntravenous iron supplementation effect on tissue iron and hemoproteins in chronically phlebotomized lambs.
Chronic phlebotomy is an important mechanism of iron loss in premature infants. We studied inter- and intraorgan iron allocation in 10 twin lamb pairs undergoing an acute 40-50% reduction in red cell volume followed by smaller intermittent phlebotomies over an 11-day period. One twin received no supplemental iron sucrose, while the other received an average daily intravenous dose of iron sucros...
