| dc.description | Bangladesh is an agro-based country and about eighty percent of its people live in
villages and most of the villagers are poor. Poultry may play a very important role
for income generation and poverty reduction particularly for the distressed women
and youths in the country as a means of self-employment.
Poultry rearing is considered superior to the other sector in agriculture because of
an almost assured and quick return in a relatively short period of time. There has
been a tremendous development of this sector in recent years.
Almost each and every village home of Bangladesh holds 6 to 7 chickens and
accordingly there is approximately a 140 millions of chickens scattered in the
country (Rahman, 2003). The advancement of poultry industry is being hampered
by various fatal infectious and non-infectious disease problems, which cause 30%
mortality of chickens that has been estimated to cost about Tk. 8,000 crores
annually in Bangladesh (Ahmed and Hamid, 1991). | en_US |
| dc.description.abstract | The present study was conducted to determine the seroprevalence of Salmonella
infections in selected layer farm. This study covered cultural prevalence with
isolation and identification of the causal agent of Salmonellosis in layer farms of
Rangpur district during January-June 2011. The overall seroprevalence of
Salmonella by Serum Plate Agglutination test was 40.41% .In flock no. 1, the
prevalence of Salmonella infection was 40.32% at first sampling but it increased
to 44.23% at second sampling (2 months later first sampling). The prevalence of
Salmonella infection also increased from first sampling to second sampling from
37.40% to 45.45% in flock no. 2, 36.53% to 46.66% in flock no. 3, 38.18% to
43.33% in flock no. 4 and 32.72% to 39.34% in flock no. 5. A total 498 isolates
originating from various tissues and environmental samples were characterized,
among them 60% were Salmonella pullorum, 20% were Salmonella gallinarum
and 20% were Paratyphoid group of Salmonellae. Seasonal prevalence of
Salmonellosis was higher in summer (26.89% ) than the winter season( 20.25%).
From the antibiogram study it was revealed that all of the isolates were sensitive
to gentamicin (100%), ciprofloxacin (100%), followed by norfloxacin (90%),
tetracycline (60%), streptomycin (30%) and amoxycillin (30%) penicillin G and
apicillin are resistance. | en_US |
