Feline leukemia and feline immunodeficiency virus infections are two widespread diseases that affect the health of domestic cats all over the world. In Algeria, despite the existence of a large population of cats, there are no published data regarding the epidemiological status of feline retroviruses. Therefore, the objective of the present study was to estimate the seroprevalence of FIV and FeLV infections in cats in Algiers and to assess the main factors associated with the infection. A cross-sectional study was conducted in which 71 cats were sampled from several private veterinary clinics, and their obtained sera were tested using an immunochromatography analysis (SNAP Duo FIV/FeLV Test; Virbac Laboratories, France). The seroprevalence was about 32.39% and 22.53% for FIV and FeLV, respectively. Overall, 11.26% were positive for both infections. The present study showed that FIV seropositivity was associated with a younger age and health status ( < 0.05), while FeLV seropositivity was associated with the sex, reproductive status, housing, age, and health status of the cats. This preliminary study, which utilized rapid tests, provides important initial data revealing a relatively high prevalence of retroviruses in cats in Algeria. The results underscore the urgent need for implementing both preventive and management measures to control the spread of these retrovirus diseases. However, to enhance the reliability of future findings, it is essential to expand the sample size and incorporate reference diagnostic methods.

Given the limited data on the real-life therapeutic use of feline McDonough sarcoma (FMS)-like tyrosine kinase 3 (FLT3) inhibitors in Italy, we surveyed investigators at 59 Italian hematology centers to gain insight into the proportion of acute myeloid leukemia (AML) patients receiving FLT3 inhibitors and we collected data on the efficacy and safety of these agents. The survey results showed that in the real-life setting the response rate of the 3/7 + midostaurin regimen in newly diagnosed FLT3-mutated AML and of gilteritinib in the relapsed/refractory AML were comparable to that reported in the registrative clinical trials. The 3/7 + midostaurin treatment resulted in a 63% of complete remission (CR) rates and gilteritinib in a 44% of CR rates.

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.).

Infectious diseases can have detrimental effects on wildlife populations, particularly those that persist at small sizes, have low genetic diversity, and are affected by fragmented habitat. One such example is the endangered Florida panther (Puma concolor coryi), which has been intensively managed since the early 1980s, with the current population ranging between 120 and 230 individuals. For more than three decades, panthers have been captured, demographics recorded, and blood samples collected to monitor for multiple infectious diseases; however, an updated comprehensive study of many of these pathogens has not occurred since 1991.
