“…This association has led meat inspectors and slaughterhouse workers to assume that WSK could be indicators of past or current leptospiral infection, and kidneys were condemned as a consequence (Uzal et al 2002). Leptospires have been isolated from kidneys of clinically healthy slaughtered sheep in New Zealand (Blackmore et al 1982), Australia (Gordon 1980) and Brazil (de Azevedo et al 2004), and clinically healthy slaughtered cattle (Prescott et al 1987;Uzal et al 2002) and pigs (Peet et al 1983;Baker et al 1989;Campagnolo et al 2000). Thus, infected animals pose an occupational health risk of leptospirosis to meat workers.…”

“…Serovar hardjo has been isolated from naturally infected sheep in New Zealand (Bahaman ef all980). Victoria (Gordon 1980) and Northern Ireland (Ellis et a / 1983), and from experimentally infected sheep in New Zealand Hathaway and Marshall 1979 The organism, although isolated from renal tissue, has not previously been histologically demonstrated in the kidney. This brief report details the demonstration of leptospires in kidney sections of a sheep by silver staining.…”

“…Gordon (32) and Hathaway (33) concluded that, despite presenting certain resistance to the disease status, sheep were infected by Leptospira spp. through contaminated water and pasture, especially by the serovar Hardjo, and once the infection was established the animals acted as hosts, carriers and releasers of the bacterium in the urine for more than two months.…”

Leptospirosis is a zoonosis distributed worldwide, endemic mainly in humid subtropical and tropical countries, with epidemic potential. It affects a range of both wild and domestic animals, including sheep, which transport leptospires in their urine and, therefore, can infect other animals and humans who deal with them. Therefore, leptospirosis is characterized as an occupational zoonosis. In individual herds leptospirosis can cause severe economic loss due to miscarriages and outbreaks of mastitis with a significant reduction of milk production. The disease is caused by Leptospira interrogans, which was reclassified into 13 pathogenic species, and distributed into more than 260 serovars classified into 23 serogroups. The clinical signs of infection may vary depending on the serovar and host. In maintenance hosts, antibody production is generally low; there are relatively mild signs of the disease, and a prolonged carrier state with organisms in the kidneys. In incidental hosts, the disease may be more severe, with high titers of circulating antibodies and a very short or nonexistent renal carrier state. In general, young animals with renal and hepatic failure have more serious infections than adults. Several diseases may produce symptoms similar to those of leptospirosis, so that laboratory confirmation, through microscopic agglutination test, for example, is required. The effectiveness of treatment depends on early diagnosis and appropriate therapy, depending on clinical features, since leptospirosis can develop into chronic liver disease and nephropathy, progressing towards death. Improvements in habitation and sanitary conditions, rodent control, vaccination, isolation and treatment of affected animals are the main measures for the control of leptospirosis.
