BACKGROUND Gastro-oesophageal candidiasis is a rare infection and appears mainly in debilitated or immunocompromised patients. Colonization by Candida spp. may occur in this region and the organism can remain for several months or years in the abse...

Escherichia coli is the most abundant facultative anaerobic bacteria in the gastro-intestinal tract of mammals but can be responsible for intestinal infection due to acquisition of virulence factors. Genomes of pathogenic E. coli strains are widely described whereas those of bovine commensal E. coli strains are very scarce. Here, we report the genome sequence, annotation, and features of the co...

Five strains of virus were recovered from nasal washings and feces. Four strains were of human origin, the fifth strain came from a monkey sacrificed at the height of the disease. Of the four human strains the first was isolated from the feces of a 14 year old child 7 days after the onset of illness. The second strain was from the nasal washings of a 6(1/2) year old child, 5 days after the onse...

3 We demonstrated recently that Cryptosporidium parvum IOWA strain induces in situ ileo-caecal 4 adenocarcinoma in an animal model. Herein, the ability of another C. parvum strain and other 5 Cryptosporidium species to induce digestive neoplasia in dexamethasone-treated SCID mice was 6 explored. SCID mice infected with C. parvum TUM1 developed a fulminant cryptosporidiosis 7 associated with int...
