The immunizing effect of inactivated sporulated oocyst and inactivated sonicated vaccines against bovine coccidiosis was observed in calves. Indirect haemagglutination (IHA) test was developed for detecting antibodies to coccidian. Serum antibody levels in calves were measured against soluble oocyst (sporulated) antigen. IHA antibody titer was significantly higher (P<0.05) in calves vaccinated ...

Vaccines derived from the lentogenic and mesogenic strains are used for the protection of clinical ND in chickens. No information is available on the protection offered by these vaccines against virus replication and shedding in Nigeria. This study compared the abilities of La Sota and Komarov vaccines to protect chickens against replication and shedding in chickens challenged with the velogeni...

The present study evaluated the effect of Lactobacillus plantarum as a probiotic on the growth performance and haematological parameters of juvenile rainbow trout (O. mykiss) weighing 29.6±1.8 g immunized with streptococcus/lactococcus vaccine. Fish were randomly allocated into 4 equal groups consisting of fish fed with the probiotic  supplemented in diet (group P), fish immunized with streptoc...

Four groups of Dekalb Delta commercial layer hens (8 hens per group) were reared individually in cages in an isolation unit. At the age of 8 weeks, groups 1 and 2 were vaccinated with 9R Salmonella gallinarum live (9R live) vaccine. At the age of 18 weeks, group 1 was re-vaccinated with 9R live S. enteritidis vaccine, while groups 2 and 3 were vaccinated with S. enteritidis bacterin. At the age...

bovine tropical theileriosis caused by theileria annulata is an economically important disease of cattle. an enzyme linked immunosorbent assay (elisa) was used to determine antibody levels in vaccinated and unvaccinated cattle, us¬ing cellular schizont as antigen and its results were compared with immunofluo-rescent assay (ifa). for this test 126 sera collected (105 vaccinated, 31 not vacci¬nat...

Rotaviruses (RV) are a major cause of gastroenteritis in children. Widespread vitamin A deficiency is associated with reduced efficacy of vaccines and higher incidence of diarrheal infections in children in developing countries. We established a vitamin A deficient (VAD) gnotobiotic piglet model that mimics subclinical vitamin A deficiency in children to study its effects on an oral human rotav...

Many mouse models of breast cancer have been developed that closely replicate human breast cancer subtypes at the genomic level. In order to develop vaccines that could prevent a broad spectrum of breast cancer subtypes, a combination of different spontaneous tumor models are needed. Transgenic models are available that mimic HER2+/luminal breast cancer (TgMMTV-Neu) and triple negative/basal-li...
