Studies of Leptospira Hebdomadis

Leptospirosis in small mammals of Iran; 1. Serologic tests and isolation of Leptospira hebdomadis from Apodemus sylvaticus

Benign leptospirosis: first reported outbreak in British Isles due to strains belonging to the Hebdomadis serogroup of Leptospira interrogans.

The clinical and epidemiological features associated with the first reported outbreak in the British Isles of benign anicteric leptospirosis, due to strains belonging to the hebdomadis subgroup, are described. Four cowherdsmen working in two dairy farms in Surrey developed a febrile illness which was not associated with jaundice, but aseptic meningitis was a feature. Microscopic agglutination t...

Comparison of Bacterial Burden and Cytokine Gene Expression in Golden Hamsters in Early Phase of Infection with Two Different Strains of Leptospira interrogans

Leptospirosis, a zoonotic infection with worldwide prevalence, is caused by pathogenic spirochaetes of Leptospira spp., and exhibits an extremely broad clinical spectrum in human patients. Although previous studies indicated that specific serovars or genotypes of Leptospira spp. were associated with severe leptospirosis or its outbreak, the mechanism underlying the difference in virulence of th...

Restriction endonuclease DNA analysis of Leptospira interrogans serovars icterohaemorrhagiae and hebdomadis.

Antigenic variants of Leptospira interrogans serovars copenhageni and hebdomadis were examined by bacterial restriction endonuclease DNA analysis with EcoRI, XhoI, SalI, BstEII, and HindIII as the digesting enzymes. The antigenic variants were stable cloned strains which had been cultivated in media containing homologous immune serum. One of the strains examined has been reported elsewhere (R. ...

Seroprevalence of Leptospira infection in bats roosting in human settlements in Morogoro municipality in Tanzania.

Leptospirosis is a neglected emerging infectious disease with high burden in Africa. Major reservoirs of leptospirosis are rodents and other small mammals. Studies of leptospirosis in bats and the extent to which they contribute to its transmission to humans and domestic animals in Tanzania are lacking. The objective of this study was to determine the prevalence of leptospirosis and local Lepto...
