Our study investigated the prevalence of feline herpesvirus-1 (FHV-1), calicivirus (FCV), immunodeficiency virus (FIV), and leukemia (FeLV) in captive Siberian tigers Northeastern China. A total 324 blood samples 33 nasopharyngeal swab collected from 2019 to 2021 three cities were by nested PCR. The results showed that 28.1% (91/324) infected with at least one virus; positive rates FHV-1, FCV, FIV 17.3%, 13.6%, 0.9%, respectively; coinfection was 13.2%. No FeLV-positive sample detected. And we found is best for FIV, FeLV detection, but swabs FHV-1. By comparing gD genes, TK gene, gI gene homology FHV-1 strains this be 91.5%-99.9% shared domestic cats. Based on a comparison nucleic acid sequences 13 FCV strains, strain HB-1926 other only about 77.7%, 99.3% 98.6% Urnaba American cat TG1 Chinese tiger, respectively.

The contraction of the global tiger population over last 100 years into small, often isolated subpopulations has made them increasingly vulnerable to impact disease. Despite this, health wild tigers continues be insufficiently funded and explored. For example, canine distemper virus (CDV), been associated with localized declines increased risk extinction, yet received little research attention in most range countries. emergence new pathogenic threats posed fresh challenges, including African swine fever (ASFV), which potential devastate boar populations, severe acute respiratory syndrome coronavirus (SARS-CoV2) implications for conservation that remain unknown. objective this review is synthesize current on their prey impacts wild. Published sources are interpreted based three mechanisms through disease can affect viability populations: (1) by reducing survival adult tigers, (2) breeding productivity, (3) carrying capacity habitat decreased abundance. Examples CDV, SARS-CoV2, carnivore protoparvovirus 1 ASFV used illustrate these processes inform discussion mitigation priorities.

Feline immunodeficiency virus (FIV) and feline leukemia (FeLV) are well-known retroviruses causing important infections in domestic cats worldwide. The goal of this study was to determine the prevalence FeLV FIV cat living indoor outdoor southern Italy.The survey conducted on 1322 stray owned from regions Campania, Basilicata, Calabria. It carried out over a 10-year period obtain more realistic picture these retroviral diseases country. status determined by enzyme-linked immunosorbent assay (ELISA) using commercial kit (SNAP Combo Plus FeLV/FIV, IDEXX). Risk factors were analysed logistic regression.The results showed that 101/1322 (7.64%) positive for antigen 110/1322 (8.32%) antibody. Twenty-six (1.97%) both infection. Our similar those published recent studies Europe. A statistically significant association (p < 0.05) found between year, province, region, lifestyle risk positivity instead associated only with year lifestyle.

The fact that wild felines are carriers of pernicious infectious viruses should be a major concern due to the potential cross-species transmission between and human or domestic animals. However, studies on virus in captive felines, especially tigers, thin ground. In this study, we screened four viruses, namely, feline parvovirus (FPV), coronavirus (FCoV), canine distemper (CDV), influenza A (IAV), blood samples 285 Siberian tigers (Panthera tigris altaica) spleen two deceased lions leo), which were collected from 2019 2021 three Tiger Parks northeast China. Nucleic acids isolated positive for FPV by PCR, rate was 4.6% (13/285) tigers. Furthermore, VP2 gene amplified nested sequences these six strains shared 98.3-99.9% homology with reference. key amino acid sites protein consistent reference strains. Phylogenetic analysis based showed FPV-positive grouped within clade closely related Asian clade. results study circulated northeastern China provided valuable information epidemiology felines. Therefore, suggest regular antibody monitoring booster immunization performed.

ABSTRACT The Amur tiger, a flagship species in wildlife conservation China, was the focus of this study, which is aimed at detecting viral infections that could threaten survival population. A total 60 tigers were examined, including 21 blood samples and nasopharyngeal swab samples. Various PCR methods used to detect viruses: standard applied identify feline parvovirus (FPV), nested for herpesvirus‐1 (FHV‐1), calicivirus (FCV), coronavirus (FCoV), leukemia virus (FeLV), immunodeficiency (FIV), qPCR canine distemper (CDV) influenza (IAV). results showed 70.0% (42/60) tested positive least one infection. Specifically, prevalence FPV, FHV‐1, FCoV 14.3% (3/21), 26.7% (16/60), 56.7% (34/60), respectively. co‐infection rate 21.4% (9/42) observed among infected tigers. No found FCV, FIV, FeLV, CDV, or IAV. Overall, first study presence China confirms their exposure FCoV.
