Salmonella and Erysipelothrix infection in swine: a laboratory summary.

The occurrence of salmonellas and Erysipelothrix rhusiopathiae in tissues of swine was determined by bacteriologic and fluorscent antibody examination of 5,297 specimens from herds investigated for hog cholera. Of the specimens examined, 35.5% were positive for salmonellas, 21.1% were positive for E rhusiopathiae, and 8.3% were positive for both salmonellas and E rhusiopathiae.

Lactose-fermenting Salmonella from dried milk and milk-drying plants.

A study of 552 salmonella cultures revealed that 86 (15.6%) of the cultures fermented lactose. These had been isolated from dried milk products and milk-drying plants. Acid and gas were produced in lactose broth. Solid media containing lactose as the key ingredient for the differential reaction were not satisfactory for recognizing salmonella colonies. No problem was encountered in selecting salmonella colonies when bismuth sulfite agar was used.

The isolation of influenza viruses.

Of 129 strains of the Hong Kong variant of influenza A2 virus isolated from 176 respiratory infections, 105 (81.4%) were isolated in tissue culture, the remainder being detected only by the inoculation of fertile hen's eggs. Organ cultures of chick embryo trachea were at least as sensitive as monkey kidney tissue culture for the isolation of this virus but organ cultures of human embryonic ciliated epithelium were much less efficient. The reverse was true for strains of influenza B virus studied in 1970 and 1971 when eggs and chick embryo tracheal organ culture were of little value and organ cultures of human embryonic ciliated epithelium and monkey kidney tissue cultures were the systems of choice.

Viruses associated with acute respiratory infections in Royal Air Force personnel.

All respiratory illnesses which were reported to the medical officers between September 1966 and December 1967 on a Royal Air Force station of 350 men were studied virologically.THREE PERIODS OF INCREASED RESPIRATORY INFECTIONS WERE OBSERVED: two occurred in the autumn, one in each year, and the third in the winter during January and February. The autumnal outbreaks were associated mainly with rhinovirus infections, and high isolation rates (82.1, 65.9%) were achieved at these times. Few of the illnesses during the winter outbreak could be diagnosed in the laboratory, and no evidence was found of infection with ;coronaviruses'.Despite the entrance of 30 fresh recruits direct from civilian life every 5 weeks, the respiratory infections encountered on the station were very similar to those in the local population and were not predominantly infections with adenoviruses, Coevirus, and Mycoplasma pneumoniae, as previously reported from larger military recruit centres.
