Leptospirosis distribution related to freshwater habitats in the Vojvodina region (Republic of Serbia).
ABSTRACT The retrospective study (2002-2007) for human leptospirosis in Vojvodina was undertaken in order to describe the distribution of the disease in relation with some environmental factors. Regarding the presented results, the major detected number of leptospirosis cases concurs with stagnant waters, wetlands, fish pond areas and protected regions, which comprised the basis for mapping of the region in three risk zones: very high risk (incidence rate higher than 5.0), high risk (2.5-5.0) and medium risk of leptospirosis infection (1.0-2.5). During the investigated period, 97 cases were registered with an average of 13.85 cases per year: 2002, 32 cases; 2003, 7; 2004, 22; 2005, 16; 2006, 4 and 2007, 16. Out of these 97 cases only 5 were women. Serovars from 11 presumptive serogroups caused infection, with a predominance of Icterohaemorrhagiae and Bratislava, accounting for 72.72% of cases together. Icterohaemorrhagiae was the commonest infecting serogroup mostly connected with fish ponds. Case fatality ratio was 9.4%.

ABSTRACT: A worker on a trout farm died from serologically confirmed leptospirosis. Four other workers at the trout farm had recently had an influenza-like illness; one had had jaundice. The man with jaundice had high leptospiral antibody titres, and two others had titres of 1/30. The remaining serum sample was negative. Family members and neighbours not associated with the farm had no detectable leptospiral antibodies. There was evidence of rat infestation around the ponds and in a shed used for storing trout food. Pond water or trout food contaminated with rat urine is believed to have been responsible for the outbreak. Another case occurred in a fish farmer elsewhere and it is thought he was infected through wading in rat polluted water with defective rubber boots. A survey to determine the incidence of leptospirosis in fish farm workers is under way.The Lancet 10/1981; 2(8247):626-7. · 39.06 Impact Factor

ABSTRACT: We found antibodies to leptospires in 25 (18%) of 141 wild boars from Berlin (95% confidence interval 12-25). Seropositivity was associated with chronic interstitial nephritis (odds ratio 10.5; p=0.01), and leptospires were detected in kidney tissues. Wild boars represent a potential source for human leptospirosis in urban environments.Emerging infectious diseases 06/2007; 13(5):739-42. · 5.99 Impact Factor
