Group C streptococci commonly cause infection in animals but only occasionally give rise to severe infection in man. We report here three cases of serious human infection due to this organism and discuss its pathogenicity in relation to the clinical manifestations of the disease.

Rickettsia africae, a recently identified pathogen, was detected for the first time in Amblyomma ticks from Niger, Mali, Burundi, and Sudan, and "R. mongolotimonae" was identified for the first time in Africa. Rickettsiae of unknown pathogenicity and two new ehrlichiae of the Ehrlichia canis group were identified in ticks from Mali and Niger.

The study of phylogenetic groups and pathogenicity island (PAI) markers in commensal Escherichia coli strains from asymptomatic Chinese people showed that group A strains are the most common and that nearly half of all fecal strains which were randomly selected harbor PAIs.

A case of overwhelming post-splenectomy infection is described. This occurred 10 years after splenectomy in an otherwise normal male adult. The infecting organism, ,3-haemolytic Streptococcus Group B, is usually of low pathogenicity, but in this case caused profound hypotension, jaundice and the shock lung syndrome. Overwhelming post-splenectomy infection with this organism has not previously b...

We report a fatal case of necrotizing soft tissues infection caused by an Escherichia coli strain belonging to phylogenetic group C and harbouring numerous virulence factors reported to be part of a pathogenicity island (PAI) such as PAI IIJ96 and conserved virulence plasmidic region.

Edwardsiella piscicida is a new species discovered within the group of organisms traditionally classified as Edwardsiella tarda. We present draft genome sequences of two variant strains of E. piscicida, JF1305 and RSB1309. Differences in protein-coding sequence between these isolates are associated with virulence, disease, and defense, suggesting differences in pathogenicity.

UNLABELLED Batrachochytrium dendrobatidis is the causative agent of chytridiomycosis, which is considered one of the driving forces behind the worldwide decline in populations of amphibians. As a member of the phylum Chytridiomycota, B. dendrobatidis has diverged significantly to emerge as the only pathogen of adult vertebrates. Such shifts in lifestyle are generally accompanied by various degr...

Abstract Small GTPases of the Rab family play important roles in membrane trafficking and autophagy. Previous studies have shown that small GTPase Sec4 is involved vegetative growth, protein secretion, pathogenicity fungal phytopathogens. In this study, BcSec4, an ortholog yeast Sec4p protein, was characterized Botrytis cinerea . The ΔBcSEC4 mutant produces many abnormal conidiophores; it thus ...

In the AbstractIn sentence beginning with “Pathogenicity test was conducted by inoculating healthy 6 weeks old tomato plants conidial suspension of Cladosporium tenuissimum ...”, term “conidial suspension” should have read “fungal suspension”.The correct is:“Pathogenicity fungal and Koch’s postulates were fulfilled phytopathogen re-isolation identification.”

The spotted fever group of Rickettsia consists of multiple species anging from microorganisms with unknown pathogenicity such s “Candidatus Rickettsia amblyommii” (hereafter R. amblyommii) o potentially lethal pathogens such as R. rickettsii, the causative gent of Rocky Mountain spotted fever (RMSF) in humans. Rickttsia amblyommii is found mainly in ticks belonging to Amblyomma enus, and report...
