“…The MAT was performed at the Laboratory of Infectious Diseases of UFU and a cutoff dilution of 1:25 was established, which was previously used on crocodilians [3] . A panel of 22 serovars was used: Andamana, Autumnalis, Australis, Bataviae, Bratislava, Canicola, Cynopteri, Copenhageni, Djasiman, Grippotyphosa, Hardjo, Hebdomadis, Icterohaemorrhagiae, Javanica, Panama, Patoc, Pomona, Pyrogenes, Sentot, Tarassovi, Whitcombi and Wolfii.…”

Microscopic agglutination test on captive rattlesnakes : Data on serovars and titers

et al. 2016

The microscopic agglutination test (MAT) is considered the “golden standard” leptospirosis serodiagnostic test, but there is little information about it as it pertains to snakes. To fill this information gap, we provide data on serovars and titers of fifty-six Crotalus durissus collilineatus sera samples that tested positive by MAT (10.1016/j.actatropica.2016.02.006 (Rodrigues et al., 2016) [5]). These data are presented in a table, along with a description of the methodology used for sample collection and serologic testing.

“…Although, studies reporting the exposure of free-living reptiles to infectious pathogens are limited, knowledge concerning this population is important, given the attempts to reintroduce or translocate reptiles (CALLE et al, 2001). ROSSETTI et al (2003) identified 67 reactive crocodiles (22 free-living) in which the possible infectious path was the aquatic environment that they inhabited, demonstrating a means of Leptospira persistence.…”

Negative results for anti-Leptospira sp. agglutinins in free-living Iguanas (Iguana iguana) from the Amazon region of Brazil

et al. 2018

Although, serological studies for leptospirosis in iguanas have already been performed, there is no report in the Amazon region. Therefore, the present study aimed to investigate the presence of anti-Leptospira sp. in free living Iguanas-verdes (Iguana iguana) of Mangal das Garças Park, metropolitan region of Belém, Pará, Northern region of Brazil. Twenty-nine blood samples of Iguana-verde (I. iguana) were collected from Mangal das Garças Park. For the serological diagnosis of Leptospira sp. it was employed microscopic agglutination test (MAT) with 25 live antigens of Leptospira sp. as antigens. It was observed that all samples were non-reactive, suggesting no exposure to the agent.

“…Leptospirosis is a worldwide zoonotic disease caused by the infection of a pathogenic spiroquete of the genus Leptospira (Levett 2001, Bharti et al 2003, Vijayachari et al 2008 and is considered a reemergent disease given its increase in prevalence and the occurrence of new pathogenic strains (Bengis et al 2004, Mahajan & Daljeet 2008, Pappas et al 2008, Vijayachari et al 2008. A wide variety of animals such as mammals, reptiles and amphibians may serve as reservoir of the pathogenic Leptospira interrogans (Seijo et al 2002, Rossetti et al 2003, Brihuega & Tealdo 2011 and may be a source of infection to humans and other domestic and wild animals (Michel et al 2001, 2002, Bharti et al 2003, Masuzawa et al 2006. The existence of periodic epizootics may cause significant die-offs in mammals, as reported for example in marine mammals (Cameron et al 2008).…”

First isolation of Leptospira interrogans from the arboreal squirrel Callosciurus erythraeus introduced in Argentina

et al. 2013

We isolated Leptospira strains from renal tissue samples of Asiatic red-bellied squirrels Callosciurus erythraeus, captured in Argentina. In December 2008, we captured 34 squirrels in the province of Santa Fe during a short control campaign, which were screened for Leptospira spp. by direct immunofluorescence assays and isolation attempts in renal tissue samples. A prevalence of 38% of Leptospira spp. was obtained by direct immunofluorescence. The isolates, genotyped by the MLVA, were identified as L. interrogans Canicola (N¼ 2) and L. interrogans Icterohaemorraghiae (N¼ 1), showing an identical genetic profile to the reference strains Hond Utrech IV (serovar Canicola, serogroup Canicola) and M20 (serovar Copenhageni, serogroup Icterohaemorrhagiae), respectively. Our study shows for the first time that the red-bellied squirrel is a renal carrier of Leptospira interrogans and might act as a reservoir of leptospirosis both in native range and areas of introduction within several European countries, Japan and Argentina. The close association of this introduced squirrel species with humans and domestic animals may increase the probability of disease transmission, particularly in favourable environments.
