The detection of Salmonella enterica serovar Enteritidis (SE) in eggs is hampered by a typically low prevalence of contaminated eggs, the low number of SE organisms in such eggs, and the presence of inhibitory substances in the egg albumin. For these reasons, the analysis of large pools of eggs is normally necessary, which presents logistic and microbiological challenges associated with a low n...

The effect of cholesterol enrichment and depletion of rabbit erythrocytes on the activities of membrane-bound enzymes, namely (Na+,K+)-stimulated ATPase, NAD+ase and acetylcholinesterase was examined. The cholesterol content of erythrocyte membranes has been modified by incubation of intact cells with sonicated egg lecithin/cholesterol vesicles (cholesterol/phospholipid molar ratio approx. 2) a...

Oviposition site selection by gravid females is an important determinant of the distribution, abundance, and dynamics of dipteran hematophagous insects. The presence of conspecific immature stages in a potential oviposition site could, on the one hand, indicate the suitability of that site but on the other hand could indicate the potential for intraspecific competition. In this paper, we presen...

A review of the literature has revealed a scarcity of attempts to compare directly various methods proposed for the detection of Salmonella organisms in food products. Unfortunately, often it has been assumed that methods useful in clinical or public health laboratories, engaged in identifying cases and carriers, are also suitable for the examination of food products. Furthermore, in many insta...

The study was conducted to evaluate the effects of different dietary oil sources supplementation on laying hens’ performance and fatty acids profile of egg yolks. Seventy-two 23-week-old laying hens (Tetra-SL) divided into six experimental diets (four replicates and three birds per replication) in a completely randomized design for nine weeks. Experimental diets were included: 1) control (no oi...

background: campylobacter spp. are the common pathogens that infect human beings via food. these bacteria are vibrio and have been implicated in abortion. serotyping is the best way for typing with penner scheme. c. jejuni and c. coli have 65 serotypes. c. coli is common in birds and dogs. due to high rate of prevalence of campylobacter in red-meat, chicken-meat and egg-shell, a suitable method...
