EPIDEMIOLOGICAL STUDY ON SALMONELLA SPPISOLATED FROM GOAT IN SOME PROVINCES INMIDDLE OF IRAQ

Abstract

This study aimed to isolate salmonella bacteria from the goats in the four
goverenent in central Iraq (Babylon, Karbala, Najaf, Baghdad), where the number of
animals examined 710 head goats in the fields and slaughter houses, 350 samples of
feces from 350 animals from the
fields while the number of animals at slaughter houses 360 collected from them
360 fecal samples and 1440 samples from different organs (the gall bladder , the
intestine, mesenteric lymph nodes and spleen) for the purpose of bacterial isolation
serological diagnosis.
fifty one (51) Salmonella isolates were isolated from the feces and organs at a
percentage (2.37%), and was returning to the four serotypes (S.hato, S.typhimurium,
S.hadar, S.enteritidis), serotype S.typhimurium constitute the highest percentage of
infection (70.83%).
Percentage of infection in field animals 2.29% and highest in Baghdad (4%) and in
slaughter house animals the percentage was 4.44% and highest in Babylon (4.9%),
The results showed that during six months of study on the goats examined at
slaughter houses, and seven months on goats examined in the fields clear difference,
and the higest percentage 8.3% in slaughter house and 4% in fields appeared in
march.
One handerd and ninety three (193) examined animals showed different symptoms
(diarrhea , respiratory signs , increased body temperature dullness or more than one
symptom) ,but only 11 animals were found infected with Salmonella, the diarrhea
constitute high percentage (5.08%), while 517 animals appeared normal (without
signs). However, 13 animal gave positive results for Salmonella which constitute
2.52% .
In animals from slaughter houses the percentage of infection were varied in
examined organs and faeces, in bile duct the percentage was 3.06%, 2.57% for each
of the spleen and mesenteric lymph nodes and 1.944% from intestine and feces
,while the percentage in feces of field animals showed 2.285%.
There was no significant difference between males and females, the percentage of
infection recorded in females 3.82%, whereas, in males 2.90%. According to the age
the infection percentage was more in animals below six months of age 5.59%.
The sensitivity test of the species against antibiotics was studied, the results
showed that they are sensitive to (cefotaxime, chloramphenical, trimethoprime
sulfamethaxazole, and must species were resistant to ampicillin.
