Species identification, antibiotic sensitivity and slime production of coagulase negative staphylococci

Forty-five isolates, of CNS isolated from various clinical sources, were included in this study. Species identification for the strains was done using the API Staph. Staph. epidermidis and Staph. haemolyticus were the most common species identified. Slime production test was positive among 75.5% of the total isolates. All the Staph. haemolyticus [100%] and [76.7%] of Staph. epidermidis strains were slime producers. Among other species of CNS, one strain of Staph. scurii was a weak slime producer. Antibiogram for the isolates was done and an association of the slime production and multi-resistance was noticed. All, but one of the slime producers of Staph. haemolyticus, displayed multi-resistance, and all, but two of the slime producers of Staph. epidermidis strains, displayed multi-resistance

Food deprivation and intestinal mucosa of rat. A histological and surface-ultra structural study

Thirty adult male albino rats were categorized into 3 groups; namely, a control, a starved and a refer group after starvation. Specimens were taken from the proximal half of the small intestine for histological, photometric, histochemical and electron microscopic scanning studies. The intestinal mucosa of the starved rats revealed a significant decrease in the length of the villi as areas of mucosal ulceration. Re-feeding of the rats for 5 days after 5 days of starvation was associated with a reversal of the previous changes
