Salmonellainfection: Diagnosis and control

Salmonella Brandenburg - emergence of a new strain affecting stock and humans in the South Island of New Zealand

“…Control measures for salmonellosis in calves have been reported previously by Robinson (1970). To reduce the risk to people on farms contracting the disease, they should use disposable gloves when handling infected material; avoid putting fi ngers, dog whistles and cigarettes into the mouth until hands have been washed in disinfectant; avoid taking contaminated clothing or footwear into the house; clean and disinfect footwear and farm machinery; and exercise care with young children in respect to exposure to contaminated material and infected animals.…”

“…comm.). In the 1960s, a common practice in New Zealand of confi ning cattle to one or two paddocks during the last few weeks of pregnancy was reported to increase the risk of exposing newborn calves to Salmonella if infection was present in the herd (Robinson 1970). …”

Isolation of salmonellae and other potential pathogens from the freshwater aquarium snail Ampullaria

“…Organisms of the genus Salmonella are among the most widely distributed pathogens in nature, and Salmonella infection is widespread in humans and other animals throughout the world (4,18). Because of its universal incidence, its diverse manifestations, and its complex epidemiology, salmonellosis now constitutes a serious threat to the health of humans and other animals (18,25).…”

Veterinary epidemiology in New Zealand: a 50-year perspective

“…Selenium defi ciency (Andrews et al 1968) received much attention as it became more evident and widespread as pastures became more intensively managed. The Salmonella Investigation Unit at Ruakura provided new and valuable insights into the diagnosis and control of salmonellosis in dairy cattle and calves (Robinson 1966(Robinson , 1970. Large-scale perinatal lamb mortality studies began as veterinary practice-based surveys in Gisborne and Ashburton with the support of the then New Zealand Meat and Wool Board, while Quinlivan's studies were fi nanced by the New Zealand Romney Breeder's Association, heralding a sharing of responsibility for research between govern-Veterinary epidemiology in New Zealand: a 50-year perspective R Jackson * ment and farmer organisations.…”
