The potential of motile Aeromonas species to cause human gastrointestinal infections has been recognised recently. Considerable worldwide epidemiological, microbiological and clinical investigations have shown that some strains of the different motile aeromonads are of increasing enteropathogenic significance, especially in children, the elderly and in(More)
Cytotoxic and haemagglutinating properties were determined in 114 Aeromonas strains isolated from various sites in slaughtered lambs and from processed lamb meat. Cytotoxic activity on Vero cells was observed in 48 (42%) of the strains. It was more common in A. sobria and A. hydrophila isolates than with A. caviae isolates. Haemagglutination (HA) activity(More)
The ability of 60 strains of Aeromonas to produce enterotoxin and haemolysin after cultivation at 5 degrees C for 7-10 d was investigated. The strains were isolated from lamb meat, offal, carcasses and faeces, and had previously been tested for their ability to produce these exotoxins at 37 degrees C. The results showed that some strains of Aeromonas(More)
The state of household waste recycling in Lahore city, Pakistan with a population of 7.2 million was analyzed. Data on solid waste recycling were gathered from residents of low-, middle- and high-income groups, as well as from scavengers and junkshops. The recycling activities in Lahore exert a significant impact on resource conservation, creation of jobs,(More)
Enrichment in alkaline peptone water was compared with the direct plating method for the isolation of Aeromonas spp. from lamb meat and offal samples. The enrichment method significantly increased the isolation rate of aeromonads. Motile Aeromonas species (A. hydrophila, A. sobria and A. caviae) were present in all kinds of samples investigated.(More)
The ability of enterotoxigenic strains of Aeromonas hydrophila and Aeromonas sobria to produce exotoxins (enterotoxin and haemolysin) in a meat extract at low temperatures (5 and 12 degrees C) was investigated. All three strains incubated at 12 degrees C were enterotoxigenic and haemolytic in the meat extract after 5 days. At 5 degrees C, five of the six(More)
Two hundred and thirty three samples of lamb carcasses, livers, kidneys and faeces, collected at a local abattoir, were examined to determine the incidence of motile Aeromonas spp. Wash water from the abattoir was also tested. Direct plating on starch ampicillin agar and enrichment in alkaline peptone water were used. The incidence of aeromonads was low.(More)
The ability of enterotoxigenic strains of Aeromonas hydrophila and Aeromonas sobria to produce exotoxins (haemolysin and enterotoxin) and exoenzymes (protease and lipase), as well as their growth in meat slurries stored at low temperatures (5 and 12 degrees C) was investigated. The results showed that Aeromonas grew well in meat slurries stored at low(More)
