Brucellosis is considered to be the most widespread zoonosis throughout the world. It has a serious implication on human health as well as on the economic development in a developing country like Bangladesh. The objective of the present study was to determine the seroprevalence and to delineate the risk factors for Brucella seropositivity in small ruminants in Mymensingh district of Bangladesh. In the present study, serum samples were collected from a total of 2456 small ruminants (1710 goat and 746 sheep) from 13 upazilla of Mymensingh district. The data related to age, sex and location were also collected using a questionnaire. Serum samples were screened using Rose Bengal Test (RBT) and Enzyme Linked Immunosorbent Assay (ELISA). Seroprevalence of brucellosis was 9.53% in goats and 9.92% in sheep on RBT test. In goat, the highest Brucella antibody was observed in Mymensingh sadar upazilla (13%) followed by Dhobaura upazilla (12.9%). On the other hand, highest ovine Brucella antibody observed in Haluaghat upazilla (13.04%) followed by Mymensingh sadar (12.5%). The prevalence was more in adults (55.2% in goats and 57% in sheep) than young (8.6% in goat and 8.1% in sheep) and more in female goats (41.1%) and sheep (39.2%) than male goats (14.1%) and sheep (18%). ELISA test showed 33.70% (31 out of 92 RBT positive samples) positive reaction of total RBT positive reactors. The result of this study can be useful to initiate and establish a program for controlling and prevention through test and slaughter, culling of infected animal from flock and vaccination.

The importance of brucellosis is primarily due to its public health significance and economic loss for the animal industry. The present study was performed to determine the seroprevalence of brucellosis in man and animals. A total of 1,452 samples (cattle 913, buffaloes 99, sheep 40, goats 50 and persons 350) were collected from Central Cattle Breeding and Dairy Farms, Savar, Dhaka and 5 districts (Mymensingh, Jamalpur, Gaibandha, Rangpur and Bagerhat) of Bangladesh. All samples were screened by RBT and the RBT positive sera were re-tested with SAT CFT, ELISA and qRT-PCR. Out of 913 cattle and 99 buffalo sera, 48 cattle and 7 buffalo sera showed positive reaction to RBT i.e. prevalence of brucellosis is 5.3% in cattle and 7.1% in buffaloes. The 350 human sera and all sheep and goats samples were negative to RBT. Among the RBT positive sera, 12 sera were found to contain Brucella DNA by genus specific IS711 quantitative real time PCR (qRT-PCR); and all PCR positive samples were found to contain Brucella abortus DNA. This report confirms that B. abortus is endemic in cattle and buffaloes in Bangladesh. [ABSTRACT FROM AUTHOR]

Dermoid cyst is an uncommon developmental anomaly usually congenital or hereditary in nature which can result from either defective genetics or from a genetic insult/agent that's associated with the fetal environment or from their interaction. Dermoid cysts and congenital diseases are not most common in Bangladesh and the economic effect of congenital defects is not as high as compare with that of other diseases that have high economic effects. The main objective of this study is to report severe bilateral corneal dermoid with nasal hyperplastic tissue in a calf and its therapeutic measurements attended in veterinary teaching hospital, BAU.
