Virus Particles in Gastroenteritis

Detection of Enteric Viruses in Fecal Specimens from Nonbacterial Foodborne Gastroenteritis Outbreaks in Tokyo, Japan between 1966 and 1983

“…These enteric viruses were first detected by electron microscopy in stool specimens from patients with acute gastroenteritis in the 1970s (4)(5)(6)(7)(8). Subsequently, highly sensitive molecular biology techniques were developed to detect these viruses.…”

Isolation and characterization of rotavirus from feral pigeon in mammalian cell cultures

“…similar morphology (Flewett, Bryden & Davies, 1973;McNulty, 1978) and clinical signs (Flewett & Woode, 1978), share a common group specific antigen (Woode et al 1976; Thouless et al 1977), cross protection (Gaul et al 1982) and inter-species transmissions (Tzipore & Makin, 1978;Dagenais et al 1981). However, despite these findings which indicate that not all rotaviruses are species-specific, there is no direct evidence of rotavirus infection between animal species and man as a zoonosis.…”

Pathogenesis of gastrointestinal infection

“…1 Stool EM found rotavirus excreted in huge numbers so that rapid diagnosis (within minutes) on minimally prepared faecal samples was possible (Fig 1). 2,3 It also demonstrated other morphologically distinct viral particles, and in a short time non-bacterial gastroenteritis became divided up into rotavirus, adenovirus, Norwalk-like, or other viral diarrhoeas. 4 These clear diagnoses opened up viral gastroenteritis, allowed 'virus-directed' clinical and epidemiological studies and gave rational explanations for diarrhoeal episodes.…”
