Human Metapneumovirus in Turkey Poults
This study was conducted to reexamine the hypothesis that human metapneumovirus (hMPV) will not infect turkeys. Six groups of 2-week-old turkeys (20 per group) were inoculated oculonasally with 1 of the following: noninfected cell suspension; hMPV genotype A1, A2, B1, or B2; or avian metapneumovirus (aMPV) subtype C. Poults inoculated with hMPV showed nasal discharge days 4-9 postexposure. Spec...
متن کاملAstrovirus infection in hatchling turkeys: alterations in intestinal maltase activity.
Two experiments were conducted to determine intestinal disaccharidase activity in 1-day-old commercial turkey poults inoculated with astrovirus. Small intestinal samples were collected on days 0.5, 1, 3, and 7 postinoculation (PI) in Expt. 1 and on days 7, 10, and 14 PI in Expt. 2 and evaluated for specific maltase activity (SMA). Astrovirus infection was verified on day 7 PI by immune electron...
متن کاملOral Administration of Astrovirus Capsid Protein Is Sufficient To Induce Acute Diarrhea In Vivo
The disease mechanisms associated with the onset of astrovirus diarrhea are unknown. Unlike other enteric virus infections, astrovirus infection is not associated with an inflammatory response or cellular damage. In vitro studies in differentiated Caco-2 cells demonstrated that human astrovirus serotype 1 (HAstV-1) capsid protein alone disrupts the actin cytoskeleton and tight junction complex,...
متن کاملCarbohydrate malabsorption in acute diarrhea.
A group of 245 well nourished infants with acute diarrhea were screened for carbohydrate malabsorption by evaluating stool pH and reducing substances in the stools. Carbohydrate malabsorption was diagnosed in 28 cases (11%). Clinical features of carbohydrate intolerance were present in only one case. The duration of diarrhea after admission ranged from 1 to 13 days (mean 3.9 days). An oral lact...
متن کاملHeat conditioning induces heat shock proteins in broiler chickens and turkey poults.
Peripheral leukocyte heat shock proteins (HSP: HSP90, HSP70, and HSP23) from broiler chickens and turkey poults were induced by in vitro and in vivo high temperature exposure. Heat conditioning, via a daily 1 h exposure to 41 C, enhanced in vitro HSP expression in leukocytes from chickens heat-conditioned for 1 to 2 wk, and a similar response was found in turkey poults with 3 wk of heat conditi...
