Feline leukemia virus in owned cats in Southeast Asia and Taiwan.

Feline leukaemia virus (FeLV) is a retrovirus associated with fatal disease in cats with infection in its progressive form. Although there are numerous reports on the occurrence of FeLV in the feline population worldwide, there is a paucity of data in Asia. In this study, we assessed the circulation of FeLV by ELISA and nested PCR in cats from different countries in Southeast Asia (i.e., Thailand, Malaysia, Singapore, Philippines, Indonesia and Vietnam) and Taiwan during 2017-2018. Forty-seven cats were positive to FeLV by antigen or provirus detection, but 32 samples were considered truly positive on the basis of positive molecular testing. Frequency of occurrence of FeLV proviral DNA ranged from 0% (0/43 positive samples) in Indonesia to 18.5% (22/119 positive samples) in Thailand. A statistically significant association (p < 0.05) was found between country of cats origin, age, lifestyle, abnormal oral mucosa, and FeLV molecular positive results. In-depth studies are needed in other countries in Southeast Asia to elucidate the mosaic of knowledge about FeLV epidemiology.

[Toxoplasmosis: a survey on meat products in Côte d'Ivoire]. / Toxoplasmose: à propos d'une enquête sur la viande en Côte d'Ivoire.

Toxoplasmosis is a worldwide parasitic zoonosis that can cause severe problems under certain circumstances. Before the advent of the last-generation anti-retroviral drugs, estimation predicted that 50% of HIV-infected patients would develop toxoplasmosis (mainly central nervous system forms). It is the first clinical manifestation of AIDS in 20% of patients. This report describes an epidemiological survey on the seroprevalence of Toxoplasma antibodies in bushmeat and pork in the Côte d'Ivoire. The purpose was to determine how the parasite circulates among wild and domestic animals and to evaluate the risk of transmission to humans after ingestion of these meats. Fifteen samples of bushmeat were purchased on markets in 6 different cities. A total of 91 single samples of fresh pork raised at three different modern breeding facilities were collected from a slaughterhouse in Abidjan. Serological testing was performed on muscle fluid using an ELISA test (Pourquier Toxoplasma kit). No bushmeat sample was positive. Global seroprevalence in pork samples was 8.8% [range, 8.2-9.37]. The seroprevalence of toxoplasmosis measured in pork samples produced at modern livestock breeding facilities was lower than values reported in samples produced by traditional breeding in Africa. This finding suggests that the use of modern techniques excluding rodents (good hygiene) can reduce animal contamination. Curing (heat and smoking) may account for the absence of Toxoplasma antibodies in bushmeat. Public information campaigns concerning the risk of consuming meat containing cysts as well as raw vegetables contaminated with oocysts are needed to prevent transmission of toxoplasmosis.
