“…Feline astrovirus was first described in cats in 1981 (Hoshino et al, 1981). To date, picornavirus-like particles as well as astroviruses from feces of domestic cats have been described in Australia, England, Germany, New Zealand and the USA (Harbour et al, 1987;Herbst and Krauss, 1989;Hoshino et al, 1981;Marshall et al, 1987;Rice et al, 1993). The impact of AstV infection in cats seems to be low as infection of specific-pathogen free kittens caused two episodes of pyrexia and mild diarrhea (Harbour et al, 1987).…”

Astroviruses are small, non-enveloped, positive sense, single-stranded RNA viruses first identified in 1975 in children suffering from diarrhea and then described in a wide variety of animals. To date, the list of animal species susceptible to astrovirus infection has expanded to 22 animal species or families, including domestic, synantropic and wild animals, avian, and mammalian species in the terrestrial and aquatic environments. Astrovirus infections are considered among the most common cause of gastroenteritis in children, second only to rotavirus infections, but in animals their association with enteric diseases is not well documented, with the exception of turkey and mink astrovirus infection. Genetic variability has been described in almost all astrovirus species sufficiently examined infecting mammals and birds; however, antigenic variability has been demonstrated for human astroviruses but is far less investigated in animal viruses. Interestingly, there is an increasing evidence of recombination events occurring in astroviruses, which contributes to increase the genetic variability of this group of viruses. A wide variety of species infected, the evident virus genetic diversity and the occurrence of recombination events indicate or imply either cross-species transmission and subsequent virus adaptation to new hosts or the co-infection of the same host with different astroviruses. This can also favor the emergence of novel astroviruses infecting animals or with a zoonotic potential. After more than 30 years from their first description in humans, there are many exciting streams of research to be explored and intriguing questions that remain to be answered about the relatively under-studied Astroviridae family. In the present work, we will review the existing knowledge concerning astrovirus infections in humans and animals, with particular focus on the molecular biology, interspecies transmission and zoonotic potential of this group of viruses.

“…This is significant, because MAstV-2 has been directly linked to enteric disease in cheetahs and has been proposed to cause enteric disease in the domestic cat, as well. 3,19 Within the MAstV-2 clade, there appear to be 3 separate groupings of astroviruses present in Alachua County, FL (Fig 1). It is important to note that, even though ACAS samples represented <45% of the sampled population, 15 of the 16 most closely related MAstV-2 sequences were from samples collected at the ACAS site.…”

Determination of the diversity of astroviruses in feces from cats in Florida

Astroviruses are small, nonenveloped RNA viruses that have been linked to numerous diseases in a variety of species, including enteric disease in humans and cheetahs. Species Mamastrovirus 2, previously known as feline astrovirus, has been isolated from the feces of domestic cats and cheetahs. A total of 122 cat fecal samples from Alachua County, FL Animal Services and the Veterinary Community Outreach Program at the University of Florida were analyzed, and 35 contained astroviral RNA that was amplified and identified using consensus RT-PCR and sequence analysis. Using phylogenetic analysis, 19 of the astroviral sequences were identified as Mamastrovirus 2, making it the most prevalent astrovirus in this population. Three samples were identified as an astrovirus similar to viruses previously identified in foxes in The Netherlands and a cat in California, and one was similar to a bat astrovirus. One astroviral sequence was identified as an Avastrovirus. Although a causative relationship between mamastroviruses and enteric disease in cats has yet to be established, it is clear that mamastroviruses are prevalent, and an understanding of prevalence of astroviral types may help direct future test development.

“…8 Subsequent EM-based investigations demonstrated that FAstV may be common in the stool of cats with and without diarrhea. 14,21 Experimental infection with a FAstV strain in specific pathogen-free (SPF) kittens induced enteritis and viral excretion for several days. 7 However, FAstV is not included in the diagnostic algorithms of feline enteric diseases, and its role as a primary pathogen or synergistic agent remains unclear.…”

Mixed infection by Feline astrovirus and Feline panleukopenia virus in a domestic cat with gastroenteritis and panleukopenia

Abstract. Astroviruses are important pathogens of human beings and animals. Feline astroviruses have been identified by electron microscopy in the feces of either asymptomatic or symptomatic cats, and experimental infection with one isolate was shown to induce enteric clinical signs and virus excretion, thus suggesting a possible role as enteric pathogen. However, due to the lack of specific diagnostic assays, feline astroviruses are not included in the diagnostic algorithms of feline infectious diseases, and their role as feline pathogens remains unclear. The present report describes a dual infection by Feline astrovirus and Feline panleukopenia virus in a 4-month-old cat with severe gastroenteritis and panleukopenia. Upon sequence analysis, the Feline astrovirus strain was found to be genetically related to astroviruses identified in human beings and felids.
