Experimental Infection of Sheep at 45 and 60 Days of Gestation with Schmallenberg Virus Readily Led to Placental Colonization without Causing Congenital Malformations.
of SBV infection and none of them had RNA emia or anti- SBV antibodies prior to colostrum uptake. Positive SBV RNA detection in organs was rare in both G45 and G60 lambs (2/11 and 1/10, respectively). ...
Prediction of respiratory disease and diarrhea in veal calves based on immunoglobulin levels and the serostatus for respiratory pathogens measured at arrival.
a decrease in ADG. This study showed the importance of providing sufficient colostrum to veal calves and the potential benefit of the presence of BCV and BRSV antibodies at arrival to reduce the BRD hazard in ...
The impact of naturally-occurring, trans-placental bluetongue virus serotype-8 infection on reproductive performance in sheep.
(4) the presence of antibody at birth in viable lambs prior to the intake of colostrum (n=9). The evidence provided by this investigation strongly suggests that trans-placental BTV-8 infection occurs in ...
Anti-TNF-alpha therapy does not ameliorate disease in a model of acute virus-endotoxin mediated respiratory disease in pigs36852
elucidate the role of TNF-alpha in the development of virus-endotoxin-induced respiratory disease. Twenty-two caesarean derived colostrum deprived pigs were used. Initially, the availability in the lungs and ...
Transplacental infection and apparently immunotolerance induced by a wild-type bluetongue virus serotype 8 natural infection.
newborns. BTV RNA was present in 41% and 18.5% of aborted foetuses from dams with or without suspected BTV involvement during pregnancy, respectively. The results of dam/calf pairs sampled before colostrum ...
Putative roles of the CNF2 and CDTIII toxins in experimental infections with necrotoxigenic Escherichia coli type 2 (NTEC2) strains in calves.
colostrum-restricted calves were orally inoculated with an Escherichia coli strain, identified originally as non-pathogenic, and into which the plasmid pVir was conjugally transferred. This resulted in diarrhea, ...
Necrotoxigenic Escherichia coli type-2 invade and cause diarrhoea during experimental infection in colostrum-restricted newborn calves.
Cattle Diseases Colostrum Diarrhea Electrophoresis, Gel, Pulsed-Field Escherichia coli Escherichia coli Infections immunohistochemistry In Situ Hybridization Abstract: There exists experimental evidence ...
Specific serum and local antibody responses against Cryptosporidium parvum during medication of calves with halofuginone lactate.
A (IgA), IgM, and IgG were monitored by an enzyme immunoassay in C. parvum-infected calves after medication with halofuginone lactate. In a first experiment, four groups of five 1-day-old colostrum ...
