Escherichia coli in meat products

One hundred samples of eaw meat products, fresh minced meat, fresh sausages, frozen beefburger and basterma slices, 25 each, were collected from different markets in Cairo. The samples were examined for determination of the incidence and enumeration of E. coli by using direct plate count technique [DPC] and multiple tube fermentation technique [MPN] as well as biochemical and serological identification of the enteropathogenic E. coli. The incidences of E. coli were 26% and 30% of the examined meat products by using DPC and MPN respectively. The incidence of E. coli in minced meat sausage, frozen beef burger and basterma slices was 44%, 40%, 12% and 8% by using DPC, and 48%, 48%, 16%, and 8% by using MPN respectively. Of 30 E. coli isolates, 12 [40%] possessed the classic enteropathogenic E. soli serovars O[124]:K[72] 4 strains O[68]:K[61], O[44]:K[74] [2 strains each], O[25]:K[11], O[78]:K[80], O[111], K[58], O[127]:K[63] [one strain each]. Principles for production of meat products of good microbiological quality were discussed as well as public health significance of EPEC

Study of duodenal biopsy in chronic renal failure

Forty uremic patients and thirty normal controls were the subject of this study. They were subjected to upper gastrointestinal endoscopy and biopsy from the duodenum to study the mucosal changes and evidence of hyperplasia of Brunner's glands. It was found that the mucosal changes in chronic renal failure [CRF] patients was present in 57.5% compared to 20.3% in normal controls. Brunner's gland hyperplasia alone was present in 42.5% in CRF as compared to 3.33% in normal controls. Duodenal polyps were found in 12.5% of patients with CRF compared to 0% in normal controls. The possible causes of these changes were multifactorial and were discussed
