“…Dominant serovars can be changed in a region from time to time. This is because old and well-established serovars may adapt themselves into new hosts, which subsequently create risk of infection [ 35 , 36 ].…”

Various prevalence studies on Leptospira in animals and humans, as well as environmental samples, had been conducted worldwide, including Malaysia. However, limited studies have been documented on the presence of pathogenic, intermediate, and saprophytic Leptospira in selected animals and environments. This study was therefore conducted to detect Leptospira spp. in rats, soil, and water from urban areas of Sarawak using the polymerase chain reaction (PCR) method. A total of 107 rats, 292 soil samples, and 324 water samples were collected from April 2014 to February 2015. Pathogenic Leptospira was present in 5.6% (6/107) of rats, 11.6% (34/292) of soil samples, and 1.9% (6/324) of water samples. Intermediate Leptospira was present in 2.7% (8/292) of soil samples and 1.9% (6/324) of water samples. Saprophytic Leptospira was present in 10.3% (11/107) of rats, 1.4% (4/292) of soil samples, and 0.3% (1/324) of water samples. From this study, 76 Leptospira spp. were isolated. Based on DNA sequencing, the dominant Leptospira spp. circulating in urban areas of Sarawak are pathogenic Leptospira noguchii, intermediate Leptospira wolffii serovar Khorat, and saprophytic Leptospira meyeri, respectively. Overall, this study provided important surveillance data on the prevalence of Leptospira spp. from rats and the environment, with dominant local serovars in urban areas of Sarawak.

“…Our results confirm wolf exposure to leptospires of different origins. Dogs are considered the natural host for serovar Canicola ( André-Fontaine 2006 ), though other species can be found infected by this serovar ( García et al 2013 ). Given the genetic proximity between wolves and dogs, it is not surprising that this was the most prevalent serovar detected in the present survey.…”

“…No information is available about leptospiral infections in rodents in the study areas. In a nearby region in western Spain, the most common serovar found was Ballum ( García et al 2013 ). The abovementioned serovars were almost absent in wild ungulates in Asturias, as recently published ( Espí et al 2010 ).…”

The Iberian wolf (Canis lupus) is the top predator in the Iberian environments in which it lives, feeding on a wide range of species, thus encountering a wide range of disease agents. Therefore, the wolf can serve as sentinel of environmental contamination with pathogens. We investigated the exposure of free-living wolves to 14 serovars of Leptospira interrogans sensu lato. Kidney samples from 49 wolves collected from 2010-2013 in northwestern Spain were analysed by culture, direct immunofluorescence and polymerase chain reaction. Tissue fluids were analysed for antibodies by a microscopic agglutination test. Ten wolves (observed prevalence: 20%, 95% confidence interval = 11-33%) showed evidence of contact with leptospires, eight through direct detection and nine through serology (7 wolves were positive according to both techniques). Titres below the cut-off level were also detected in seven cases. Serovars confirmed were Canicola (n = 4), Icterohaemorrhagiae (n = 3) and Sejroë, Ballum and Grippotyphosa (n = 1 each), indicating that wolves were infected with serovars for which dogs, rodents and ungulates, are the natural hosts and supporting the utility of the wolf and other large predators as environmental sentinels for pathogens.

“…Finally, the predatory habits of felines increase the possibility of transmission of pathogens carried by their prey. Leptospira interrogans, which causes one of the most frequent zoonoses in the world and has rodents and other small mammals as its most important maintenance reservoir in outdoor farms (García et al, 2013); indirectly, human presence in the landscape increases the probability of infection by fostering rodent populations.…”
