RESUMO
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.

Giardiosis is one of the most frequent parasites of dogs and cats. Since several years, the treatment is based on the use of metronidazole. A coproscopic study in four dog kennels was conducted to demonstrate, at a significant level, the efficacy of oxfendazole (Dolthène, Merial). At the posology of 11.3 mg/kg each day during three days (D1, D2 and D3), no dogs eliminated Giardia cysts and all dogs are clinically cured. The importance of hygienic measures is underlined. In kennels 1 and 2 where hygienic conditions were poor, dogs reexcreted cysts again after treatment. In kennels where the boxes were disinfected, no dogs, treated with 22.6 or 11.3 mg/kg, reexcreted Giardia cysts.

Autopsy of two Woodchuck Hepatitis Virus (WHV) infected Woodchucks, Marmota monax, revealed the presence of two parasites in an hepatic localization, Taenia mustelae (Larvae) and Calodium hepaticum. The authors present the identification of the two parasites, based on the observation of cysticerci of Taenia mustelae, or on the observation of the eggs of C. hepaticum. They discuss the probable interaction between hepatic parasites and WHV infection.
