Characterization of bacterial pathogens from egg shell, egg yolk, feed and air samples of poultry houses

Abstract

This study was selected to find out the bacterial pathogens in egg yolk, egg shell, feed and air samples of poultry houses at Dinajpur district in Bangladesh with isolation, identification and characterization of bacterial pathogens present in those samples. For this study, a total of 147 samples comprising egg shell (36), egg yolk (36), feed (45) and air (30) were collected during the period from January to May, 2012 and the collected samples were then examined for the bacteriological study by using cultural, morphological and biochemical techniques. On the basis of their cultural, morphological and biochemical properties the isolated organisms were identified as Escherichia coli, Staphylococcus spp., Salmonella serovars and Bacillus spp. In this study it was observed that out of 147 samples a total of 51 were identified as bacterial pathogens in which egg shell containing 10 (27.78%), egg yolk 11 (30.56%), feed 20 (44.44%) and air 10 (33.33%) respectively. In this study it was also observed that the highest prevalence of bacterial pathogens in feed samples (44.44%) in comparison with egg shell (27.78%), egg yolk (30.56%) and air samples (33.33%). In this study it was demonstrated that out of four (04) pathogens Escherichia coli was more abundant (39.21%) in the layer house and its environment in comparison with Staphylococcus spp. (25.49%), Salmonella (23.52%) and Bacillus spp. (11.76%) respectively.

“…Almost similar prevalence of Salmonella spp. (23.52%) was also reported previously [30]. Contamination of egg by Salmonella spp.…”

Characterization of Staphylococcus aureus isolated from chicken and quail eggshell

“…Out of 300 eggs, 58 (19.33%) eggshells yielded growth of Staphylococcus spp., which was supported by Syed et al [17] in Pakistan, who reported 21.3% prevalence of Staphylococcus spp. However, the prevalence found in our study was comparatively higher than the findings of Parveen et al [18], Eid et al [19], Chaemsanit et al [20], Pyzik et al [21], and Pyzik and Marek [22] who observed the prevalence was 5.5%, 14.5%, 18%, 7.61%, and 15.6% in Dinajpur (Bangladesh), Sharkia (Egypt), Thailand, and Lubin city, respectively. The prevalence of Staphylococcus spp .…”

“…Penelitian Parveen et al (2017) menunjukkan bakteri yang ditemukan dalam kerabang telur diantaranya adalah Staphylococcus spp. (5.55%), Escherichia coli (11.11%), Salmonella serovars (2.77%) and Bacillus spp.…”

“…(8.33%). Parveen et al (2017) juga menambahkan kontaminasi bakteri dipengaruhi oleh beberapa faktor yaitu lingkungan pembibitan, praktik pemuliaan, sistem perkandangan, letak geografis, dan musim. Selain itu, kontaminasi juga dapat terjadi selama transportasi telur dan atau pengemasan di peternakan atau di tempat penyimpanan, baik melalui lingkungan atau dari satu telur ke telur lainnya.…”
