In feline () infection and in clinical cases of feline leishmaniosis, co-infection with feline immunodeficiency virus (FIV) has been reported. However, the role of the retroviral co-infection in the impairment of feline clinical health is still controversial. The aim of this study was to evaluate hemogram changes in cats from regions endemic for both and FIV infection. Four hundred and ninety-six cats tested for (EDTA blood polymerase chain reaction and immunofluorescence antibody test) and for FIV infection (enzyme-linked immune assay) were retrospectively evaluated. Hemogram results including blood smear morphological evaluation were statistically compared considering four infection patterns: +FIV+, +FIV-, -FIV+, and -FIV-. Significantly lower values of erythrocytes (+FIV-: = 0.0248; -FIV+: = 0.0392) and hemoglobin (+FIV: = 0.0086; -FIV+: = 0.0249) were found in both infections when compared to -FIV- cats, and severity of anemia was more frequently moderate in -positive cats ( = 0.0206) and severe in FIV infection ( = 0.024). infection was associated with monocytosis ( = 0.0013) and morphologically activated monocytes ( = 0.0209). Moreover, FIV infection was associated with the presence of inflammatory leukogram ( = 0.023), and an association between thrombocytosis and the co-infection was found ( = 0.0347). infection in cats induces hematological changes compatible with chronic inflammation, some of which are due to co-infection with FIV.

With the increasingly close coexistence between pets and humans, coupled with reports of Cryptosporidium cross-infection between felines and their guardians, research aimed at understanding the epidemiology of these parasites in specific regions has become necessary. The principal objective of this study was to undertake a molecular characterization of Cryptosporidium in fecal samples from felines in the state of Goiás, Brazil (which is unprecedented for the region), and to assess the risk factors involved in the infection of these animals in the aforementioned locale. A total of 95 fecal samples were collected from domestic felines in the municipality of Goiânia, Goiás, Brazil.

The primary aim of this study was to determine the accuracy of saliva as a proxy for blood in cats using Anigen Rapid FIV point-of-care (PoC) kits and as an easy collection technique applicable for all veterinary clinics and shelters. A secondary aim was to report FIV prevalence in various Australian states/territories and key cat risk factors associated with FIV infection. In total, 382 cats were recruited from patients presenting to private, shelter and teaching hospital veterinary clinics in Australia.

Feline leishmaniasis is increasingly recognized as a disease affecting cats worldwide, with notable prevalence in regions surrounding the Mediterranean Basin and in Brazil. An approximately one-year-old domestic shorthair cat was presented with small papules and nodules (2 mm) on the nasal planum. Physical examination and routine blood analyses were normal.

Feline immunodeficiency virus (FIV) is a retrovirus affecting domestic cats worldwide and causing immunosuppression and reduced quality of life. The prevalence of FIV infection varies according to geographic regions / countries and it is associated with domestic cat health managements (vaccination, neutering, basic health care, etc.).

This study is aimed at documenting the indigenous knowledge and quantitative analysis of medicinal plants (MPs) used by traditional health practitioners (THPs) of Urambo District in mid-western Tanzania to manage respiratory tract disorders (RTDs). The ethnomedicinal data were collected using semistructured interviews with 55 THPs using a snowballing technique in the district. The data were analysed for indigenous knowledge among gender, age groups, education status, and experience.
