ABSTRACT
This study was conducted to investigate the status of brucellosis in dairy cattle from five selected dairy farms in the Mohammadpur Beribadh area of Bangladesh. A cross-sectional study was carried out from October 2010 to March 2011 in which a total of 334 serum samples from cattle in five herds were screened by the Rose-Bengal plate-agglutination test (RBPT) and the positives were confirmed using an indirect enzyme-linked immunosorbent assay (I-ELISA). A structured questionnaire was used to collect epidemiological information describing the animals. Overall, 4.20% of the animals were RBPT positive, while subsequent confirmatory tests with I-ELISA revealed that the overall animal-level prevalence derived from the samples was 1.20%. Additionally, the prevalence was relatively higher in females than in males. A significant association was found between abortion, age of the animals, and the occurrence of brucellosis (p < 0.05). Considering the overall low prevalence of brucellosis in the selected farms in the present study, a brucellosis eradication program for dairy farms using a test-and-slaughter policy would be possible.

Clinical presentations of kala-azar [visceral leishmaniasis] are varied in children and adults. This may at Least initially mimic many tropical and hepatobilliary diseases. This paper is an attempt to see the clinical presentations of kala-azar in children. Eleven cases are analyzed, retrospectively admitted in a pediatric unit of a tertiary care hospital in the southern part of Bangladesh. Fever 91%, Jaundice 55%, splenomegaly 100%, hepatomegaly 91% are common findings. Presence of jaundice and ascites may mimic chronic liver disease which is suspected in 36% in this series. Awareness regarding these uncommon features will help in diagnosis
