“…in cats (SHERRY et al, 2011;SOBRINHO et al, 2012), a positive statistical association between infections by T. gondii and L. infantum and N. caninum and L. infantum, which was indicative of coinfections, was detected in this study. Numerous studies have reported immunosuppression caused by Leishmania spp., which could enhance the susceptibility to the parasite when immunosuppressive events are not involved.…”

An investigation was made into the occurrence of antibodies to Toxoplasma gondii, Leishmania infantum and Neospora caninum in 151 domestic cats, based on the indirect fluorescent antibody test (IFAT). Serum samples were collected from 151 domestic cats (65 free-roaming and 86 domiciled cats; 55 males and 96 females) in Campo Grande, Mato Grosso do Sul, Brazil between January and April 2013. IgG antibodies to T. gondii, L. infantum and N. caninum were found, respectively, in 49 (32.5%), 34 (22.5%) and 10 (6.6%) sampled cats. A positive correlation was found between T. gondii and N. caninum, T. gondii and L. infantum, and N. caninum and L. infantum (p < 0.05) infections. Also, a significant interaction was identified between gender and area of activity on the probability of T. gondii (p = 0.0324) infection. However, no significant interaction was observed between gender and area of activity on infections by either N. caninum or L. infantum. This study showed that cats from an area endemic for visceral leishmaniasis in Brazil are exposed to three different protozoans, two of which are causal agents of important zoonosis.Keywords: Cats, Leishmania infantum, Neospora caninum, Toxoplasma gondii, serology, Brazil. ResumoO presente estudo teve como objetivo investigar a ocorrência de anticorpos anti-Toxoplasma gondii, Leishmania infantum e Neospora caninum, em 151 gatos, por meio da Reação de Imunofluorescência Indireta (RIFI). Entre os meses de janeiro e abril de 2013, amostras de soro foram coletadas de 151 gatos domésticos (65 gatos errantes e 86 gatos domiciliados; 55 machos e 96 fêmeas), de Campo Grande, Mato Grosso do Sul, Brasil. Anticorpos IgG anti-T. gondii, anti-L. infantum e anti-N. caninum foram encontrados em 49 (32,5%) , 34 (22,5%) e 10 (6,6%) gatos amostrados, respectivamente. Verificou-se uma associação estatisticamente significativa entre as infecções por T. gondii e N. caninum, T. gondii e L. infantum e N. caninum e Leishmania infantum (p < 0,05). Além disso, foi observada uma interação significativa entre sexo, área de atividade na probabilidade de infecção por T. gondii (p = 0,0324). No entanto, não foi observada interação significativa entre sexo e área de atividade nas infecções por N. caninum e L. infantum. Este estudo mostrou que os gatos de uma área endêmica brasileira para leishmaniose visceral são expostos a três diferentes protozoários, sendo dois deles importantes agentes zoonóticos.

“…In other studies, prevalence of Leishmania spp infection in cats by PCR-based tests was reported as 8.7% (Sherry et al, 2011) and 25.7% (Martín-Sánchez et al, 2007) in Spain, 10% in Iran (Hatam et al, 2010), and 20.3% in Portugal (Maia et al, 2010). Peripheral blood has been the most commonly used specimen in PCR-based feline surveys and positive results ranged from 0.3% to 60.7%, among cats living in regions endemic for canine and/or human leishmaniosis (Martín-Sánchez et al, 2007;Tabar et al, 2008;Maia et al, 2008;Ayllon et al, 2008;Maia et al, 2010;Sherry et al, 2011;Millán et al, 2011;Ayllón et al, 2012;Vilhena et al, 2013).…”

More recently in Greece PCR positivity in different tissues from cats ranged from 3.1% (conjunctival swab) to 16% (bone marrow), 18.2% (skin biopsy) and 13% (blood) in clinically normal cats and in cats with various clinical signs living in the region of Thessaly (central Greece) and Thessaloniki (north Greece), thus indicating the need for multiple tissue PCR testing in order to avoid underestimating of the true prevalence of the infection (Chatzis et al, 2014).…”

In this study we aimed to determine the prevalence of Leishmania spp infection and to report the geographical distribution of Leishmania spp infected cats from Thessaly, central Greece, an endemic region for canine and human leishmaniosis. Blood samples were collected from a total of 150 cats (34 stray and 116 owned) from the area of Thessaly, i.e. Larissa (n=6), Volos (n=94), Trikala (n=30) and Karditsa (n=20). Data on signalment and living conditions were registered for each cat. The samples were tested by Internal Transcribed Spacer 1 nested PCR (ITS1 nested PCR). Geographical Information System (GIS) was used to define the geographical distribution of the Leishmania spp infected cats in relation to the land uses and the altitude. In total, 13.3% (95% CI: 8.3-19.8) of the sampled cats were found positive for Leishmania spp DNA. More precisely, the results are 12.8% (95% CI 6.8-21.2) in Volos, 20% (95% CI 6.8-21.2) in Trikala and 10% (95% CI 12-31.7) in Karditsa while none of the six cats examined from the region of Larissa was found PCR positive. The Leishmania spp infected cats were found in artificial surfaces and associated areas and in cultivated and managed areas with a mean altitude of 81,7 m above sea level (range 14 - 225 ± 51.57 SD). No significant correlation was found between Leishmania spp infection and signalment or living conditions, thus suggest ing that the infection is uniformly distributed among the screened feline population. The findings of this study along with the occurrence of competent vectors of Leishmania infantum in Thessaly, support the hypothesis that cats may serve as a reservoir for Leishmania spp in this region and highlight the need for surveillance in feline population and implementation of control measures. However, the epidemiological role of cats in the maintenance and transmission of Leishmania spp has yet to be defined and deserves further investigation.

Ghosts of Christmas past?: absence of trypanosomes in feral cats and black rats from Christmas Island and Western Australia

S U M M A R YTrypanosomes and Leishmania are vector-borne parasites associated with high morbidity and mortality. Trypanosoma lewisi, putatively introduced with black rats and fleas, has been implicated in the extinction of two native rodents on Christmas Island (CI) and native trypanosomes are hypothesized to have caused decline in Australian marsupial populations on the mainland. This study investigated the distribution and prevalence of Trypanosoma spp. and Leishmania spp. in two introduced pests (cats and black rats) for three Australian locations. Molecular screening (PCR) on spleen tissue was performed on cats from CI (n = 35), Dirk Hartog Island (DHI; n = 23) and southwest Western Australia (swWA) (n = 58), and black rats from CI only (n = 46). Despite the continued presence of the intermediate and mechanical hosts of T. lewisi, there was no evidence of trypanosome or Leishmania infection in cats or rats from CI. Trypanosomes were not identified in cats from DHI or swWA. These findings suggest T. lewisi is no longer present on CI and endemic Trypanosoma spp. do not infect cats or rats in these locations.
