“…This information is crucial for control of FeLV infection in domestic cats as there is currently no data on its prevalence in Zimbabwe. The FeLV p27 antigen in blood samples in this study (41%) is higher than those from both developing (Bande et al 2012;De Almeida et al 2012) and developed (Bandecchi et al 2006;Gabor et al 2001;Lee et al 2002;Little et al 2009) countries in other regions where moderate (10% -20%) to low (< 10%) prevalences have been reported. The observed data may be influenced to an extent by test parameters, a small sample size and sampling bias -as cats presented to veterinary clinics only may not be representative of other apparently healthy cats that did not visit the clinics.…”

A cross-sectional study was conducted to detect the feline leukaemia virus (FeLV) p27 antigen and to determine risk factors and the haematological changes associated with infection in domestic cats in Zimbabwe. Sera were collected for detection of the p27 antigen, urea, creatinine, alanine aminotransferase and gamma-glutamyl transferase levels, whilst whole blood was collected for haematology. FeLV p27 antigen was detected using a rapid enzyme-linked immunosorbent assay (ELISA) test kit. Data on risk factors were analysed using a logistic regression model. Of the 100 cats tested, 41% (95% CI: 31.19% - 50.81%) (41/100) were positive for the FeLV p27 antigen. Sex and health status of cats were not significantly (p > 0.05) associated with infection. Intact cats (OR = 9.73), those living in multicat housing (OR = 5.23) and cats that had access to outdoor life (OR = 35.5) were found to have higher odds of infection compared with neutered cats, those living in single-cat housing, and without access to outdoor life, respectively. Biochemistry and haematology revealed no specific changes. The results showed that FeLV infection was high in sampled cats, providing evidence of active infection. Thus, it would be prudent to introduce specific control measures for FeLV infection in Zimbabwe.

“…FIV is associated to HIV, which can induce immunosuppression in some cats, according to the phase of infection. FeLV is associated to human T lymphocytic virus and can also cause immunosuppression in cats (Little 2011;Tiao et al 2013). FeLV and FIV are two common and important retroviral pathogens of cats all over the world (Dunham and Graham 2008).…”

“…FeLV and FIV are two common and important retroviral pathogens of cats all over the world (Dunham and Graham 2008). Diseases associated with FeLV and FIV may affect any organ, including lymphoma, blood dyscrasias, central nervous system and eye diseases, gingivostomatitis, and secondary and opportunistic infections (Little 2011). Previous studies of cat serum have demonstrated an association between seropositivity for T. gondii and these two viral pathogens in some countries (Dorny et al 2002;Maruyama et al 2003;Dubey et al 2009).…”

Toxoplasma gondii, Dirofilaria immitis, feline immunodeficiency virus (FIV), and feline leukemia virus (FeLV) infections in stray and pet cats (Felis catus) in northwest China: co-infections and risk factors

This study was conducted to estimate the prevalence of Toxoplasma gondii, Dirofilaria immitis, feline immunodeficiency virus (FIV), and feline leukemia virus (FeLV) infections among stray and pet cats in Lanzhou, northwest China, and to identify the influence of age, gender, and regions on seropositivity. T. gondii antibodies were examined in cat sera by the modified agglutination test (MAT). The circulating antigens of D. immitis and FeLV and specific antibodies to FIV were examined using kits commercially available. The overall prevalence of T. gondii, FIV, FeLV, and D. immitis was 19.34, 9.12, 11.33, and 3.04 %, respectively. For the genetic characterization of T. gondii genotypes in cats, genomic DNA was extracted from the seropositive cats and the T. gondii B1 gene was amplified using a semi-nested PCR. DNA samples giving positive B1 amplification were then genotyped using multilocus PCR-RFLP. Two T. gondii genotypes (ToxoDB#9 and ToxoDB#1) were identified. Results of the multivariate logistic regression analysis showed that older cats are more likely to be seropositive than juveniles for T. gondii, FIV, FeLV, and D. immitis. This is the first report of T. gondii genotypes in cats in northwest China. Moreover, the present study is the first study of retrovirus and D. immitis seroprevalence in cats in China. The results revealed that T. gondii, FIV, and FeLV infections are common in stray and pet cats in northwest China.

“…For FeLV infection, the currently overall prevalence in the mixed cat population ranges from 1-6% GLEICH et al, 2009;LITTLE et al, 2009;HELLARD et al, 2011). A prevalence study for FeLV infection in Slovenia found 23.8% positive cats (TOZON et al, 2008), and a previous paper in Croatia showed 11.5% healthy and up to 14.9% clinically ill, positive cats (KUČER et al, 2000).…”

Feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are among the most common infectious diseases of cats and have a global impact on the health of domestic cats. Both viruses belong to the Retroviridae family and like other members of this family they are associated with lifelong infection after integration of the proviral DNA into the host cell genome. Prevalence data are necessary to define the risk factors, and prophylactic, management, diagnostic and therapeutic measures for stray and owned sick cats. In this study 324 domestic cats were tested with commercially available assays. The tested cats were divided into two groups, stray and owned sick cats. The overall percentage of seropositives for FIV infection was 18.51% and the prevalence for FeLV infection was 14.50%. FIV prevalence ranged from 13.13% in stray cats up to 20.88% within the sick owned cat group. The prevalence for FeLV infection was 6.06% in stray cats and 18.22% among sick owned cats. Regarding FIV infection, our study confirmed a significantly higher percentage of seropositives for male cats, as well as for sexually intact ones within the sick owned group. Males were significantly more likely to have positive results for both retroviral infections. The study confirmed the high rate of retroviral infections in cats from the Zagreb urban area. Males, sexually intact ones, and territorial aggression are predisposing factors for FIV infection, but not for FeLV. Preventive measures should include identification and segregation of infected cats, castration of outdoor male cats, and vaccination.
