The humoral immune response of chicken vaccinated with fowl and pigeon pox virus vaccines was determined with the protective potentiality of the two vaccines in field condition of Bangladesh. Different aged Fayoumi chicks were subjected for the study. To assess the relationship with better immune response among experimental groups, the average percentage of ``take reaction`` was examined and recorded to 97.77% in group A, 93.33% in group B and 100.0% in group C. The level of immune status induced by different vaccinated group was measured by passive hemaggluti?nation(PHA) microplate test method. The mean PHA titer levels after primary vaccination were 33.06±14.13 in group A, 32.0±14.81 in group B, and 33.0±13.66 in group C. Following booster vaccination, the mean PHA titer levels in prior of challenge were increased to 55.46±14.64 in groups A and C, and 46.93±16.52 in group B. The recorded PHA titer levels of each group at two weeks after challenge were significantly increased to 106.66±31.22, 93.86±33.04 and 110.93±29.29, respectively. The PHA titer levels after vaccination and challenge were significantly increased compared to pre?vaccination titer levels(P<0.01). Although the PHA titer levels among three groups administrated different vaccine combinations in prior of challenge were significantly varied(P<0.01), it was observed that all of the vaccinated chicks were highly protected against challenge infection.

Brucella spp. are small, non-motile Gram-negative coccobacilli known to cause disease in a number of vertebrate species including humans and brucellosis is one of the world's major zoonoses, alongside bovine tuberculosis and rabies. There are about 33.55 million goats and 1.16 million sheep in Bangladesh. The sheep and goats can significantly play an important role in the economic well being of the resource-poor farmer in Bangladesh. Sexually matured 362 female small ruminants(300 goats and 62 sheep) were examined. Approximately 3-5 ml of blood was collected from the jugular vein of each animal and sera samples were prepared. Samples were then tested for brucellosis by using Rose Bengal test(RBT), plate agglutination test(PAT) and tube agglutination test(TAT). Among 362 small ruminants, irrespective of species(sheep or goat), diagnosed highest in TAT, 2.21%(n=8) and lowest both by RBT & PAT, 1.93%(n=7) and it is concluded that TAT is superior than RBT and PAT.
