ISOLATION AND CHARACTERIZATION OF <i>ESCHERICHIA COLI</i> FROM BUFFALO CALVES IN SOME SELECTED AREAS OF BANGLADESH

Abstract

The research works was conducted with a view to isolate and identify the Escherichia coli (E. coli) organism from diarrhoeic cases of buffalo reared in selected areas of Bangladesh as well the prevalence and antibiotic sensitivity pattern of the isolated E. coli in the Department of Microbiology and Hygiene, Bangladesh Agricultural University (BAU), Mymensingh-2202 during the period from April 2008 to May 2009. A total of 50 rectal swab samples were collected from 4 different places namely Haluaghat and Boira of Mymensingh, Madupur of Tangail and Kazipur of Sirajgonj districts. The samples were aseptically carried to the laboratory of the Department of Microbiology and Hygiene and subjected to different cultural, morphological and biochemical examinations. Upon cultural, morphological and biochemical examinations 23 (45%) samples were found to be positive for E. coli. The highest prevalence was found in Haluaghat, Mymensingh (53.33%) and the lowest (40.00%) in Boira, Mymensingh and Kazipur, Sirajganj. Antibiogram study revealed that the isolated E. coli was highly sensitive to Enrofloxacin and Ciprofloxacin, moderately sensitive to Cefalexin and Amoxicillin, and resistant to Nalidixic acid and Erythromycin.

A Study on the Prevalence and Etiology of Joint Ill in Calves of Cross-Breed Dairy Cattle in Six Dairy Farms of Bangladesh

“…The result coincides with the results found in a research conducted by Nuss (2012). E. coli were sensitive to Tetracycline and Doxycycline and fully resistant to Amphicillin, Nalidixic acid, Chloramphenicol and Cholistin Sulfate (Table 4) which support the research findings of Paul et al (2010). Staphylococcus sp., isolates showed distinctly sensitivity to Tetracycline and Doxycycline, moderately sensitive to Neomycin and resistance to Nalidixic acid, Chloramphenicol, Cholistin sulphate and Streptomycin (Table 4).…”

Prevalence of Multidrug Resistant Escherichia Coli in Pigeon in Mymensingh, Bangladesh

“…This study recorded 69.64% prevalence of E. coli in pigeons. Other studies recorded 78.86% prevalence of E. coli in poultry (Jakaria, 2011), 66.67% prevalence in duck (Avishek, 2010), 32% prevalence in pig (Arefin, 2009), 46% prevalence in diarrhoeic buffaloes (Paul, 2009), 41.67% prevalence in diarrhoeic sheep (Purkayastha, 2007 and 72.22% prevalence in diarrhoeic goats (Abdullah, 2007).…”

Prevalence and Characterization of Escherichia coli from Rectal Swab of Apparently Healthy Cattle in Mymensingh, Bangladesh

“…Remarkable works has been done throughout the world (Alexa et al, 2011;Kesava et al, 2011;Cookson et al, 2006;Fratamico et al, 2004;Chapman et al, 1994). In Bangladesh, several reports have been published on isolation and characterization of E. coli from different sources including rectum of different animals (Singh et al, 2012, Paul et al, 2010Zinnah et al, 2007;Ali et al, 1998;Amin et al, 1988). In these cases, prevalence of pathogenic E. coli was investigated mainly focusing on diseased or slaughtered animals, poultry and human being.…”
