Abstract
and animals . The only form of Campylobacteriosis of major public health importance is Campylobacter enteritis due to Campylobacter jejuni and Campylobacter coli. Studies in many localities of the world have shown that Campylobacter species can be more frequently isolated from the faeces of persons with diarrhoea as being in Salmonella or Shigella . Milk has been suspected as being important vehicles for transmission of Campylobacter species to humans .
A total of 300 samples (100 stool specimens from children, 100 faecal samples from dairy animals and 100 milk samples ) were obtained and investigated for the presence of Campylobacter species .
1 – Our study evaluated the incidence of Campylobacter species in milk samples from different sources (45 milk samples from Agricultural dairy farm , 30 samples from dairy shops and 25 samples from street vendors ) . The percentage of Campylobacter spp. In 45 milk samples obtained from Agricultural farm in Assuit University was 7(15.5 %) [ 5 (71.4 % ) C. jejuni and 2( 28.57 % C. coli] and in 25 milk samples from street vendors was 3( 12 %) [2 (66.66 %) C. jejuni and 1(33.33 % C. coli] but milk samples of dairy shops showed the lowest isolation rate and it was only one C. jejuni .
2 – The incidence of campylobacter organism in faecal samples of dairy cows from different farms (45 samples from Agriculutral farm in Assiut University, 20samples from Veterinary hospital in Assuit University and 35 samples from Bain Mure station were studied . Out of 100 faecal samples of dairy cows at three farms in Assiut provines the percentage was 6 (6%) and classified as 4(66.6%) C. jejuni and 2(33.3 %) C. coli .The percentage of Campylobacter organism was high In Bani-Mure station 4 (13.3%) [2(50%) C. jejuni and 2(50 C. coli) ] .While the percentage the organism was low in Veterinary hospital and Agricultural farm in Assiut University which have only one C. jejuni at each farm .
3 – Campylobacter were also isolated from 15(15%) of stool specimens taken from children from birth to 4 years old , of them 12(80%) were C. jejuni and 3(20%) C. coli. Stool samples taken from children ageing from 13-18 months showed the highest isolation rate [24% all of them were C. jejuni ] . The isolation rate at the age from birth to 6 months were two C. jejuni (8.69%) , at the age (7-12 monthes)were 6(17.6%), [ 3(50%) C. jejuni and 3(50%) C. coli ] , at the age (19 - 24 months) was one (7.69%) C. jejuni , and at age of (25 -42 months) Campylobacter species failed to be detected.
4 – The incidence of infection was lower in breast fed children 8(13.5%) of them , [6 (75%) C. jejuni and 2(25%) C.coli ] than in non breast fed children 7 (17.07%) [6 (85.7%) C. jejuni and one (14.28 %) C. coli ] .
5 –The rate of infection was higher in children who live in rural area 13(16.4%) [10( 76.9%) C. jejuni and 3(23.07%) C. coli ]than who live in Urban area 2(9.5%) [2(100%) C. jejuni ] and this due to lack of personal hygiene and environmental contamination from domestic animals , poultry and flies . The incidence of infection was high in children who live in contact with animals 10(17.5%) than who live without animal contact 5(11.6%) .
