#Cat Death Losses Due to Highly Pathogenic Avian Influenza in #SouthDakota

Updated January 13, 2025

"#Veterinarians and laboratory diagnosticians are fielding reports of death losses in cat populations linked to avian influenza infections.

"Beginning in 2022, an #H5N1 subtype of highly pathogenic avian influenza (abbreviated as HPAI) virus caused death losses in domestic turkeys and chickens in South Dakota and elsewhere in the United States, an outbreak that continues. The HPAI virus causes respiratory and multiple organ failure in affected birds, typically appearing as increased numbers of dead birds in large commercial operations, as well as smaller backyard flocks. Deaths in wild birds, typically migrating waterfowl but also other bird species, have been observed at the same time, as well as spillover of the virus into mammals, such as raccoons, foxes, skunks, and other species.

"In Spring 2024, the HPAI virus began infecting #DairyCows, causing drops in milk production and other signs of illness. Unlike infections in other species, widespread death losses have not been associated with HPAI infections in dairy cows.

"About the same time as its emergence in dairy cows, the HPAI virus was implicated in deaths of domestic cats in the vicinity of affected farms. Most affected cats showed #neurologic signs, such as #tremors or #seizures, for a short period of time before dying.

"Since that time, three cases of substantial death losses in groups of outdoor domestic cats in South Dakota have been described. In each of these cases, there has been no apparent link to dairy cows, other livestock, or domestic poultry."

Recent #Bovine #HPAI #H5N1 Isolate is Highly Virulent for #Mice, Rapidly Causing Acute Pulmonary and #Neurologic Disease, BioRxIV: https://www.biorxiv.org/content/10.1101/2024.08.19.608652v1?rss=1

Our findings suggest the recent bovine isolate possesses enhanced respiratory and #neuroinvasive / #neurovirulent properties causing fatal respiratory and neurologic disease in C57BL/6J mice.

Over the last decade, #scientists have explored the association between #GutMicrobiota & the #brain & affected #neurologic manifestations. These #studies have indicated that #gut #microbiota #influences #neurogenesis , #behavior , #emotions , #CognitiveDevelopment & progression of #neuropsychiatric diseases. A #NewStudy published in the journal #FrontiersInMedicine reviewed recent literature on the link between gut microbiota, the brain & #NeurologicalDisorders.

"Due to widespread #endothelial dysfunction and thrombosis, #COVID19 has the ability to affect nearly any organ. Pulmonary disease, specifically ARDS, may be driven in large part by vascular dysfunction & #microvascular thrombosis. Increased thrombotic events, most notably venous #thromboembolism but also myocardial infarction and stroke, have been reported. Vascular dysfunction may contribute #neurologic, renal & dermatologic manifestations
