Phylogenetic analysis of Salmonella species isolated from cows, buffaloes, and humans based on gyrB gene sequences.

This study aimed to investigate the role of dairy cows and buffaloes as reservoirs of nontyphoidal salmonelloses (NTS), to reveal the occurrence of NTS among dairy workers and children with acute diarrhea and to study the gyrB gene phylogenetic relations of the obtained Salmonella strains, 300 samples were chosen randomly from clinically infected animals, including 100 feces and 50 raw milk from buffaloes and cows. Five hundred samples were chosen randomly from healthy animals, including 150 feces and 100 raw milk from buffaloes and cows. A total of 160 stool samples were randomly chosen from healthy workers (60) and children with acute diarrhea (100).

Toxoplasma gondii infection and toxoplasmosis in North Africa: a review.

Toxoplasmosis is an important zoonosis caused by an obligate intracellular parasitic protozoan, Toxoplasma gondii. The disease is distributed worldwide and can affect all warm-blooded vertebrates, including humans. The present review aimed to collect, compile and summarize the data on the prevalence of T.
