عزل و تشخيص جرثومة Plesiomonas shigelloides و دراسة خواصها الفسلجية و حساسيتها للمضادات الحيوية مع مخطط انسيابي للتشخيص

الملخص EN

In an attempt to isolate Plesiomonas shigelliodes a total of 257 various specimens were collected.

These includes 127 diarrhoeal stools, 50 sewage water, 50 tap water and 30 appendices.

A total of 28 isolates of this bacteria were identified.

The numbers of isolates and their percentages were 21 (16.5 %) in diarrhoeal specimens, 5 (5.1 %) from sewage water and 2 (6.7 %) from appendices.

Other specimens were negative for this bacteria.

The isolates were characterized by using standard identification tests and were found to be all cytochrome-oxidase positive, motile, inositol fermenters and glucose oxidizing-fermenting and able of decarboxylation of amino acids.

However, the isolates were negative to esculin, sheep blood haemolysis and production of Gelatinase, Lipase, DNase and Urease.

They were ß-Lactamase positive.

But sensitive to Gentamycin, Nalidixic acid and Ciprofloxacin.

Through the project a most suitable transport and isolation media and flow sheet for the identification were suggested.
