Prevalence of brucellosis in ruminants in Bangladesh

Abstract

ABSTRACT:The prevalence of brucellosis was determined in the ruminants (buffaloes, cattle, sheep and goats) of five different districts viz. Bagerhat, Bogra, Gaibangha, Mymensingh and Sirajgonj of Bangladesh. A total of 550 sera samples of 105 buffaloes, 188 cattle, 127 goats and 130 sheep were screened by RBT and were further confirmed with I-ELISA. A structured questionnaire was used to collect epidemiological information on the animals. The overall serological prevalence derived from the samples was 2.87% in buffaloes, 2.66% in cattle, 3.15% in goats, and 2.31% in sheep. The prevalence was relatively higher in females than that in males in cattle, goats and sheep but, an insignificantly higher prevalence was observed in males than that in females in the case of buffalo. A significant association was found between abortion or age and occurrence of brucellosis (P < 0.01). The results of the study provide (a) a comparison of the prevalence of brucellosis in different livestock species in Bangladesh, (b) constitute baseline data for further study of Brucella infections, and (c) are a starting point for the control of brucellosis.

Seroprevalence of brucellosis in cattle in selected area of Bangladesh and comparison between Rose Bengal test and i-ELISA used for the screening of brucellosis

“…The difference between the groups was not statistically significant. In contrast to the findings of the present study, Rahman et al (2011) reported the prevalence of brucellosis in the cow aged 2.5∼4 years as 1.45 % while in the cows over four years of age as 5.31%. Similarly, Amin et al (2004) reported 2.3% and 4% prevalence in the ＜4 and ＞4 years age group, respectively.…”

Comparative Sensitivity and Specificity of Various Serological Tests for Detection of Brucellosis in Small Ruminants

“…In contrast, Rahman et al, (2011) in goats and sheep who found highest seroprevalence of brucellosis by RBPT followed by STAT and I-ELISA. Shome et al, (2006) in sheep and goats who found lower seropositivity of 7.36% by I-ELISA as compared to 9.95% by RBPT from Rajasthan, Gujarat and Karnataka.…”

Brucellosis in human and domestic animals in Bangladesh: A review

“…No prevalence of brucellosis was recorded in buffalo both in Bogra and Gaibandha districts. Age and sex as potential risk factors for brucellosis in buffalo was analyzed by Rahman et al (2011a). Recently Rahman et al (2013a) recorded prevalence of brucellosis in 99 buffaloes sera of Bagerhat and Mymensingh using RBT, SAT, CFT, I-ELISA, genus specific and species specific real time PCR (see Figure 9 for amplification of real time PCR).…”
