| Abstract |
A total of 12 water samples were collected from wells at buffaloes farms ( 8 at lower Egypt and 4 at upper Egypt ).The results indicated that 100% of wells yielded different types of microorganisms-Staphylococcus aureus (22.22%) ,Staphylo coccus epidermidis (11.11 %),Streptococcus faecalis (11.11%) , Bacillus Cereus ( 55.56 % ),Clostridium perfringens (0.0 %) , Yersinia enterocolitica ( 37.5 % ), Klebsiella pneumoniae (18.75 %) , Pseudomonas aeruginosa ( 12.5 % ), E.coli faecal pollution ( 6.25 % ),E.coli saprophyte (12.5%), Enterobacter agglomerans (6.25%), Citrobacter freundii (6.25 %),Salmonella species (0.0 % ),Shigella species (0.0 % ),Proteus species (0.0 %).Total colony count of well water / ml. sample, in 2 samples count less than 100 c.f.u., in 3 samples count more than 100 to 200 c.f.u. and in 7 samples count more than 200 to 400 c.f.u. On the other hand, M.P.N. of coliform, 4 samples were negative while it was less than 10 c.f.u. in 5 samples, less than 100 c.f.u. in 2 samples and in 1 sample count more than 100 to 200 c.f.u. While Streptococcus faecalis M.P.N.,10 samples were negative and it was less than 10 c.f.u. in 2 samples. Cl.perfringens M.P.N. was (0.0 %) for all samples. A total of 500 nasopharyngeal swabs and 500 faecal samples were collected from 500 apparently healthy buffaloes stayed on the same 12 farms from which 12 well water samples were collected. 100 % of the tested nasopharyngeal swabs yielded different types of microorganisms, Staphylococccus aureus (11.21%), Staphylococcus epidermidis (32.26%),Streptococcus pneumoniae ( 9.68 % ),Bacillus cereus ( 46.85 % ), Pasteurella multocida (9.21 % ), E.coli faecal pollution ( 2.22 % ), E.coli non-true faecal ( 13.33 % ), Yersinia enterocolitica ( 62.54 % ), Pseudomonas aeruginosa ( 8.89 %) and Proteus vulgaris (3.81%). 100 % of faecal samples yielded different types of microorganisms which were Bacillus cereus ( 50.90 % ),Streptococcus faecalis ( 14.88 % ),Streptococcus bovis ( 34.19 % ),Salmonella typhimurium (2.05 % ),Klebsiella pneumoniae (2.39 % ), E.coli ( true faecal) ( 12.82 % ), E.coli ( non true faecal) ( 36.92 % ), Yersinia enterocolitica (34.70 % ),Citrobacter freundii ( 1.88 % ), Pseudomonas aeruginosa ( 3.25 % ) and Campylobacter jejuni ( 5.98 % ). Serotyping ,pathogenicity and antibiogram of most pathogenic isolates were discussed. So, this work was planned to evaluate well water quality by : 1-Total bacterial count. 2-Coliform count. 3- Clostridium perfringens count. 4- Faecal Streptococcus count. 5-lsolation and identification of microorganisms causing contamination of water. 6-Isolation and identification of microorganisms from nasopharyngeal swabs and faecal samples from buffaloes drank these well water to study its effect on buffaloes health and production. 7- Serological identification of most pathogenic bacteria. 8-Studing the sensitivity to different chemotherapeutic agent. 9- Pathogenicity of the predominant pathogenic serovars in mice.
