pandemic (h1n1) 2009 in captive cheetah.we describe virus isolation, full genome sequence analysis, and clinical pathology in ferrets experimentally inoculated with pandemic (h1n1) 2009 virus recovered from a clinically ill captive cheetah that had minimal human contact. evidence of reverse zoonotic transmission by fomites underscores the substantial animal and human health implications of this virus.201222305505
a cluster epidemic of influenza a(h1n1)pdm09 virus infection in four captive cheetahs (acinonyx jubatus).in january 2019, four cheetahs (acinonyx jubatus) kept at a japanese zoo intermittently showed respiratory signs following the incidence of seasonal influenza in animal caregivers. respiratory materials (saliva, sputum and food tray swabs) were non-invasively collected from the four cheetahs. although we were unable to isolate the virus, the np gene of influenza a virus was detected in three of the cheetahs but not in the fourth cheetah that had nearly recovered. from a food tray swab which test ...202133576190
phylogenetic analysis of ha and na genes of influenza h1n1 viruses from 1918 to 2017.the 1918 "spanish" pandemic is the earliest known influenza h1n1 virus. since then h1n1 viruses circulated between humans and animals continuously. with the increased amount of samples of h1n1 viruses and technology development, researchers have been studying how the viruses evolved. here, we analyzed ha and na genes of h1n1 viruses from three aspects: host distribution, geographical distribution and phylogenetic analysis. the data showed hosts were predominantly human, swine and poultry, and ot ...201931230448
