Diarrhoea disease in livestock associated with Aeromonas hydrophila biotype 1.

Abstract

The genus Aeromonas has been incriminated as the causative agent of a wide range of human infection (7-9). Several studies have shown that aquatic animals harbour the hydrophila-punctata aeromonads (12,18). Homoiothermic large animals such as cattle were reported by Wohlgemuth et al. (20) and Adams et al. (1) in separate studies to be susceptible to infection with the organisms. Other workers (2,15) have isolated Aeromonas hydrophila from domestic animals. The first large-scale study of its incidence in domestic animals was by Gray (11); his work, however, did not involve diseased animals. Although human Aeromonas infection has been related to water exposure since aeromonads normally inhabit water sources (3,17), the real source of infection has not been clearly defined. The role of animal reservoirs as a potential source of human infection is much more obscure. Faeces and droppings of diarrhoeic animals have not been extensively cultured for Aeromonas nor has there been any attempt to correlate this with human diarrhoeic syndrome. An outbreak of diarrhoea was recorded in a farm in Ogun State, Nigeria. This study presents a report concerning the incidence of Aeromonas species in enteritis involving livestock in the farm. There does not appear to be any record of the recovery of A, hydrophila in livestock in Nigeria, so the following may be of interest. Faecal samples which were watery with mucous but without the presence of blood in most cases were collected in separate sterile containers from diarrhoeic animals including 75 chickens, 28 goats, 42 rabbits, 56 pigs, and 21 sheep, and were processed in the laboratory within a few hours of collection. Sampling was done on three occasions covering a period of 12 days while the disease lasted. Fresh faeces

Phylogenetic characterization of bacteria in the gut of house flies (Musca domestica L.)

“…and M. morganii could carry over in the gut from larval metamorphosis to adult eclosion (Su et al, 2010). In our clone library, the most dominant genus represented was Aeromonas, and Aeromonas hydrophila, an enteric pathogen (Efuntoye, 1996), was the dominant species. and Proteus spp.…”

“…were dominantly represented in our survey, house flies can possibly serve as putative reservoirs or vectors for these microorganisms. In our clone library, the most dominant genus represented was Aeromonas, and Aeromonas hydrophila, an enteric pathogen (Efuntoye, 1996), was the dominant species. The genus Aeromonas has been linked with wide variety of human infections, acting as primary agent as well as opportunistic pathogen to immunocompromised patients.…”

The occurrence and antibiotic resistance of motile Aeromonas in livestock

“…Motile aeromonad species have been implicated as the causative agents of diarrhea, wound infections, and septicemia in humans (Trower et al 2000), diarrhea in piglets (Dobrescu 1978) and pigs (Efuntoye 1995), abortion and reproductive problems in mares and ovine (Fontaine et al 1996;Ilhan et al 2006), diarrhea in foals (Browning et al 1991), septic arthritis in a foal (Traub-Dargatz et al 1994), diarrhea in horses (Hathcock et al 1999), septicemia in dogs (Andre- Fontaine et al 1995), mastitis in cattle (Bergman et al 1981), polyarthritis in a calf (Love and Love 1984), seminal vesiculitis in bulls (Moro et al 1999), diarrhea in sheep and goats (Efuntoye 1995), gastroenteritis in a deer (Pal et al 1989), diarrhea in rabbits (Efuntoye 1995), acute deaths in aviary birds (Shane and Gifford 1985), diarrhea in fowls (Efuntoye 1995), conjunctivitis in a pet parrot (Garcia et al 1992), hemorrhagic septicemia in a ground hornbill (Bucovus abyssinicus) (Ocholi and Kalejaiye 1990), and hemorrhagic septicemia in fish (Poffe and Beeck 1991). Focal hepatic necrosis in ferrets has been associated with infection by Aeromonas species (Hiruma et al 1986), and A. sobria was associated with abortion in dairy buffaloes (Das and Paranjape 1987) and bubalines (water buffalo) (Das and Paranjape 1990).…”

Prevalence and Antibiotic Resistance of Motile Aeromonas in Dogs

“…Motile aeromonad species have been implicated as the causative agents of diarrhoea, wound infections, and septicemia in humans (Trower et al 2000); diarrhoea (Pal et al 1989;Efuntoye 1995;Hathcock et al 1999), abortion and reproductive problems (Fontaine et al 1996;Das and Paranjape 1990), septic arthritis (Traub-Dargatz et al 1994), septicaemia (Andre- Fontaine et al 1995), mastitis (Bergman et al 1981), polyarthritis (Love and Love 1984), seminal vesiculitis (Moro et al 1999), acute deaths (Shane and Gifford 1985), conjunctivitis (Garcia et al 1992) and focal hepatic necrosis (Hiruma et al 1986) have been associated with infection by Aeromonas species in animals.…”
