Isolation of Pathogenic Leptospires from Waters Used for Recreation

Small mammals – natural reservoir of pathogenic leptospires

A total of 429 specimens belonging to 9 species of small mammals, trapped in various areas of the Czech Republic during the year 2001, were examined for antibodies against leptospires. Antibodies were found in all localities under study in 50 specimens, i.e., 11.6%, belonging to 5 species. Antibodies were most often , i.e., in 42% of positives, found in Microtus arvalis. In Apodemus spp. and Cl...

First Isolation of Leptospires from Dairy Goats in Brazil

Leptospires have never been recovered from goats in Brazil. Serum samples were obtained from 248 goats from Rio de Janeiro and from the seroreactive animals, urine samples were collected and processed for Leptospira isolation. A total of 52 positive reactions were observed, corresponding to 20.9% of the samples. The most prevalent reactions were to serovars Hardjo (36.5%), Shermani (30.8%), Ict...

Isolation, Identification, and Enumeration of Pathogenic Salmonella Serovars from Environmental Waters

Pathogenic leptospiras isolated from Malaysian surface waters.

Pathogenic leptospiras (1,424) isolated from natural waters and wet soils in Malaysia comprised 29 different serovars (synonym serotypes). All except two of the serovars had been found previously in Malaysia. The exceptional serovars were werrasingha, an Autumnalis serogroup member originally isolated in Ceylon, and a new serovar designated evansi. Serovar evansi had serological affinities with...

Differentiation of Pathogenic and Saprophytic Leptospires with 8-azaguanine.

Johnson, Russell C. (University of Minnesota, Minneapolis), and Palmer Rogers. Differentiation of pathogenic and saprophytic leptospires with 8-azaguanine. J. Bacteriol. 88:1618-1623. 1964.-The use of the purine analogue, 8-azaguanine, as a differential agent for the separation of pathogenic and saprophytic leptospires was investigated. Growth of strains of the saprophyte Leptospira biflexa was...
