The authors report a survey carried out in a cattle farm between January and April 2009 in Mateur region (Northern Tunisia). Seroprevalence by Microscopic Agglutination Test (MAT) was estimated to 81.4 ± 6% and 35 ± 2% in cows and calves, respectively. Seropositivity to more than one serovar was noticed in 91% (81/89) of infected animals. The examination of the distribution pattern of Leptospir...

The main objective of this study was to investigate the role of wild rodents as Leptospira spp. reservoirs in a suburban area of Tandil city, Buenos Aires province (Argentina), where a person had died due to pulmonary leptospirosis. The specific objectives were: to estimate the rodent density near the patient's home, to determine the serological prevalence and isolation of leptospirosis from wi...

Honduras was one of the Central American countries most severely hit by Hurricane Mitch. Torrential rains and heavy flooding created conditions conducive to a leptospirosis outbreak in the country. A group of Cuban scientists studied 68 patients from the Department of Cort�s - one of the country's hardest hit areas - presenting clinical and epidemiological profiles indicative of leptospirosis. ...

BACKGROUND Leptospirosis, a zoonosis, is a re-emerging disease, affecting populations across the globe. However, the current methods of diagnosis are time- consuming, cumbersome, imprecise or expensive. AIM To develop an assay for differential and early diagnosis of Leptospirosis. METHODS AND MATERIAL IgG based ELISA for evaluation of three antigens, namely, a gel-purified recombinant prote...

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...

Nine hundred and forty two serum samples from clinically suspected cases of leptospirosis admitted in Lokmanya Tilak Municipal General Hospital, Mumbai during July-September 2005 were tested by LeptoTek Dri-dot/Leptocheck. One hundred and sixty five positive sera by these tests were sent to I.R.R., Mumbai, for detection of leptospira IgM antibodies by ELISA (PanBio). Eighty seven positive sera ...

Leptospirosis is a zoonosis of worldwide distribution. The aim of this study was to examine the presence of antibodies against 21 Leptospira reactive serovars in Chaetophractus villosus in La Pampa province, Argentina, using the microscopic agglutination test (MAT). Pathologic changes compatible with leptospirosis and in situ detection of the agent by immunohistochemistry were studied in 24 and...

A cross-sectional seroprevalence study on leptospirosis, using microscopic agglutination test (MAT), was conducted in rural villages in Khammouane Province, Lao People's Democratic Republic, in December 2006. The overall prevalence of leptospiral infection among 406 subjects was 23.9% (95% confidence interval [CI] 19.7-28.0%). Independent risk factors for the infection, identified by multivaria...

Leptospirosis is a widely distributed zoonosis, and rats are its most common source of infection. Our goal was to determine the frequency for Leptospira infection in rodents in a farmers market in the city of Medellin. We performed a descriptive transversal study sampling 254 rodents. Rodents were bled and killed, and kidneys samples were taken. Supernatants of macerated kidneys were cultured o...

Nowadays, leptospirosis is a re‑emerging widespread infectious disease often underestimate worldwide. The National Reference Centre for Leptospirosis (NRCL), at the Istituto Zooprofilattico Sperimentale della Lombardia e dell'Emilia Romagna, Brescia (Italy), with the cooperation of all the other Istituti Zooprofilattici Sperimentali (IIZZSS), evaluated the distribution of such important zoonosi...
