Title : Sero-prevalence of contagious bovine pleuro-pneumonia disease of dairy cows at Barishal region, Bangladesh

Abstract:

Respiratory diseases of cattle are very costly and deadly disease and among them contagious bovine pleura-pneumonia (CBPP) is a silent killer, that was listed an OIE, caused by Mycoplasma mycoides subsp. mycoides, a member of the Mycoplasma mycoides. The aim of the present study was to evaluate the seroprevalence of CBPP antibody and analysis the risk factors associated with the CBPP in dairy cattle. Total eleven dairy farms in 4 upazilas of Barisal division were selected. From this dairy farm total 91 blood samples were collected and serums were preserved at -20C for further use. The ELISA kit for CBPP antibody was used to detect CBPP in the collected sample according to manufacture instructions and 450 nm filter was used to read the ELISA microplate. The results were interpreted according to the supplied literature. DNA was extracted by Favorgen blood genomic DNA extraction mini kit for polymerase chain reaction (PCR).  Among the samples about 39.56% samples were positive for CBPP antibody in this area. However, among the 4 upazilas, 52.38% samples were positive for CBPP antibody at Mehendiganj upazila and lowest CBPP antibody was detected at Barishal sadar upazila. According to cow level data analysis, it was found that numerically Holstein cattle were more susceptible to CBPP than Sahiwal cattle and female animals were more susceptible than male animals but there was no any significant difference. On the other hand, good farm hygiene practice can reduce CBPP antibody detection at dairy farm level. However, 21.98% sample were positive for CBPP in PCR result. In this study it was also found that CBPP antibody was more detected in small scale dairy farms in regards to either herd size or farm area. From this study it was concluded that CBPP antibody was more detected in Holstein cattle and good farm hygiene practice and large farm area can reduced the chance of CBPP infection.

Biography:

I graduated from Bangladesh Agricultural University, Bangladesh in 1999. And also Phd from Chungbuk National University, South Korea since 2011. I also did Post doc study from the same University in 2017-2018. Now I am working as a professor of the Department of Medicine, Surgery and Obstetrics at Patuakhali Science and Technology University since 2012 to date. I published 51 research papers nationally and internationally reputed journals. I have been involved in teaching of farm animal reproduction, treatment, including management, diagnosis, and prevention of different diseases. Also my expertization is on disease model animal production through Somatic Cell Nuclear Transfer (SCNT), in-vitro and ex-vivo model embryo production, semen analysis and processing. Apart from this I have a little experience on large and small animal surgery. I am also engaged in the pedagogy skills pool of FAO, Bangladesh.
