To the Editor: Herrmann-Storck et al. (1) investigated prognostic factors of leptospirosis and concluded that infection with Leptospira interrogans serovar Icterohemorrhagiae was linked to severe outcomes. We have concerns about this conclusion. These researchers were comparing clinical severity of disease among patients for whom serovars of infecting isolates had been identifi ed. However, in ...

Leptospirosis is endemic in Malaysia with Leptospira species extensively isolated from domestic and wild animals. Rats were found to be the principal maintenance hosts followed by cattle, pigs, and dogs. The objectives of this study were to isolate and identify Leptospira serovars circulating among swine from three different farms and also from stray dogs and cats from Klang valley, Selangor, M...

In the year 2000, three hundred and eighty-one animals werw caught in 11 locations in the pedunculate oak forests extending across the wider region of the Sava River valley, an area known as an old natural focus of leptospires. Two hundred and twenty-seven animals were investigated for leptospiral carriership, 381 were tested for the existence of specific antibodies to leptospira. Through culti...

BACKGROUND Although there is serologic evidence of exposure of cats to Leptospira spp., clinical disease is rarely reported in cats. OBJECTIVE To compare the seropositivity and urinary polymerase chain reaction (PCR) status for Leptospira spp. between healthy (H) cats and cats with kidney disease (KD), to investigate the serovars potentially involved, and to evaluate potential risk factors. ...

The MICs of 24 antimicrobials for 26 Leptospira spp. serovars were determined using a broth microdilution technique. The MICs at which 90% of isolates tested were inhibited (MIC(90)s) of cefepime, imipenem-cilastatin, erythromycin, clarithromycin, and telithromycin were all /=3.13 microg...

The prevalence of antibody to six serovars of Leptospira interrogans in cattle in Asturias (Northern Spain) was determined by the microscopic agglutination test (MAT). Using 50% agglutination or lysis at a dilution of 1:10 or more as the criteria for seropositivity, 371 of 3578 (10.36%) animals were found to react with one serovar. The most commonly detected serovars were pomona (5.59%) and gri...

The objectives of the present study were to verify the seroprevalence of anti-Leptospira spp. antibodies, identify the most frequent serovars and the risk factors associated with the infection in Uberlândia, Minas Gerais, Brazil. A total of 334 ovines blood samples were collected in 12 farms from Uberlândia municipality to be evaluated by means the Microscopic Agglutination Test (MAT) against 2...

Leptospirosis is a zoonosis of worldwide distribution, caused by Leptospira interrogans. It is a well known cause of bovine reproductive losses such as abortion, infertility, stillbirth and birth of weak calves. Inthis research, the relationship between the seroprevalence rate of Leptospira spp. infection and abortion inindustrial dairy farms of Hamedan province, Iran was studied. A total of 80...

The genus Leptospira, isolated for the first time in 1915, is one of most diverse genera bacteria which includes species worldwide. taxonomic classification was based on serological similarities strains. basic taxon serovar. More than 300 serovars are currently known. Furthermore, many years divided into two species, saprophytic Leptospira biflexa and pathogenic interrogans. introduction geneti...
