Molecular characterization of pseudomonas aeruginosa isolated from milk [electronic resource].

Includes references.

A total of 200 samples of raw and pasteurized milk (100 of each) were collected from supermarkets in Qaluobia Governorate and examined for prevalence and characterization of P. aeruginosa . The incidence of P. aeruginosa isolated from raw and pasteurized milk was 40 %and 16%, respectively. Serogrouping of P. aeruginosa isolated from examined samples revealed that serogroupes K, H and, A isolated from raw milk at frequency percentage of 40, 35, and 25, respectively, while from pasteurized milk at frequency percentage of 25, 50 and 25, respectively. For the detection of the enzyme Hameolysine, Phospholipase, Caseinase and Gelatinase revaled that for serogroupe K it were 60,50, 100 and 90 % respectively while for serogroupe H it were 54.5,45.5,100 and 81.8 % respectively and it were 42.8,28.5,100and 85.7% for serogroupe A, respectively. Concerining the pathogenicity test of P.aeruginosa isolated from milk samples it was in percent 100, 100 and 57.14 for serogroupes K, Hand A, respectively.
