Summary: Approximately 5% of cats in US animal shelters are positive for FeLV or FIV, with over 100,000 positive cats in shelters each year. This study focuses on the retroviral management practices in Florida shelters, which are characterized by chronic pet overpopulation and high shelter admissions.

Summary: Papillomaviruses can cause warts in humans and animals, and are also linked to cancer. In cats, the number of virus-related lesions has increased in recent years. Research covers the virus life cycle, associated lesions, and vaccination for prevention in domestic cats.

Summary: This study found a high prevalence of feline haemoplasmas in domestic cats in the Moscow region of Russia, with some cats being coinfected with different species of haemoplasmas. The study also showed that there was no significant correlation between haemoplasma infection and FIV or FeLV infection.

Summary: This article reports a case of basal cell carcinoma (BCC) in a cat. The BCC in this case appeared on the flank and thorax with different histological features. The flank BCC showed papillomavirus (PV)-induced cell changes, while no viral infection was found in the thoracic BCC. In addition, a novel PV DNA sequence was amplified from the flank BCC. The observations from this case contribute to the diversity of PV types and PV-induced lesions in cats.

Summary: This study describes the epidemiology and molecular characterization of Feline panleukopenia virus in Bangladesh. The overall prevalence of Feline panleukopenia in suspected cats was found to be high. Risk factors for infection include lack of vaccination, winter season, and sharing litter boxes and food utensils in multicat households. Furthermore, genetic diversity was observed among the circulating Feline panleukopenia viruses in Bangladesh.

Summary: Six types of Felis catus papillomavirus (FcaPV) have been fully sequenced from domestic cats, some of which are associated with neoplasia. A novel type of FcaPV was identified in a basal cell carcinoma with histological evidence of PV infection and intense p16 protein immunostaining. The complete genome of FcaPV7 was amplified and it is proposed to be classified within the feline Tau-PV genus. Although FcaPV7 rarely infects cats, it may be associated with skin cancer in this species.

Summary: This study investigated the impact of natural FIV infection on pet cats in Australia and found differences in clinical manifestations and survival time between FIV-infected and FIV-uninfected cats. Additionally, analysis of hematological and blood biochemical parameters in FIV-infected cats identified certain indicators that could be used as diagnostic triggers for FIV testing.

Summary: The study collected fecal samples from feral cats on St. Kitts and found a significantly higher prevalence of FIV-positive cats, which was associated with male and adult cats. However, no T. gondii DNA was detected in the feces of either FIV-positive or FIV-negative cats. Further research with a larger sample size is needed to confirm or refute the hypothesis that FIV-positive cats have a higher prevalence of shedding T. gondii oocysts than FIV-negative cats.

Summary: This study finds that FIV seropositive cats are more likely to be infected with L. infantum in canine leishmaniosis endemic areas, and their risk of L. infantum antibody positivity is higher than that of FIV seronegative cats. Pale mucous membranes, low body condition score, and oral lesions are significantly associated with the coinfection.

Summary: A cross-sectional study conducted in Lebanon between April 2020 and August 2021 found that the seroprevalence of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) among household cats was 18.84% and 13.84%, respectively. Factors associated with FIV seropositivity included younger age, health and neuter status, lymphoma, lethargy, and vomiting. FeLV seropositivity was significantly associated with male sex, neuter status, lymphoma, anaemia, lethargy, and vomiting. These findings highlight the importance of preventive measures to address FIV and FeLV-related morbidity and mortality among cats.

Summary: Longitudinal studies of cats naturally infected with feline leukemia virus (FeLV) have shown that p27 antigen concentration and proviral DNA load are highly correlated with survival outcomes. High positive cats had a significantly shorter median survival time compared to low positive cats, indicating the potential use of these biomarkers for predicting disease outcomes in FeLV-infected cats.

Summary: This study found that age and FIV infection have significant impacts on cognitive abilities in cats. Younger cats have better visuospatial working memory and problem-solving abilities, with FIV infection having minimal effects. However, older FIV-positive cats exhibit worse visuospatial working memory but no differences in problem-solving abilities.

Summary: This study found that HPV DNA was detected in 56% of lung cancer samples from HIV-infected patients, with high-risk HPV types detected in 39% of samples, and HPV-16 being the most prevalent. However, viral oncogene expression was limited to patients with previous HPV-related cancers.

Summary: This study aimed to detect and genotype feline retroviruses in Mexican domestic cats. The results showed the presence of endogenous FeLV, exogenous FeLV, and FIV in the cats, with high variability in the enFeLV sequences and subtype B FIV gag gene in the infected cats.

Summary: The study demonstrates that Feline Merkel cell carcinoma (MCC) cases are infected with FcaPV2 and the subsequent inhibition of pRb and p53 induced by integrated viral oncogenes is associated with feline MCC tumorigenesis, similar to other PV-induced proliferative cutaneous lesions. Additionally, a case of FcaPV2-negative MCC with strong p53 immunoreactivity suggests mutations in p53 caused by other cancer inducers.
