Infant salmonellosis and vacuum cleaners.

Microbiological examination of the contents of vacuum cleaner bags collected from case and control homes demonstrated a statistically significant association (OR = 3.13, CL = 1.32-7.

Trabulsiella guamensis, a new genus and species of the family Enterobacteriaceae that resembles Salmonella subgroups 4 and 5.

In 1985 the vernacular name Enteric Group 90 was coined for a small group of strains that had been referred to our laboratory as probable strains of Salmonella but did not agglutinate in Salmonella typing antisera. By DNA-DNA hybridization (hydroxyapatite method, 32P), seven strains of Enteric Group 90 were found to be closely related (98 to 100% at 60 degrees C and 94 to 100% at 75 degrees C) to the first strain received (0370-85). The relatedness of Enteric Group 90 to 62 strains of other species of the family Enterobacteriaceae was only 6 to 41%, with the highest values obtained with strains of Salmonella, Kluyvera, Shigella, Klebsiella, Enterobacter, and Citrobacter.

Observations on the ecology of Salmonella waycross and Salmonella typhimurium on Guam.

A period of high incidence of human Salmonella infections on the island of Guam saw the emergence of S. waycross as the most commonly isolated serotype as well as a concurrent decreasing proportion of isolates due to S. typhimurium.

NAG Vibrio cholerae isolated from imported shellfish in Guam.

A survey of imported shellfish available in public markets on the Island of Guam revealed the presence of NAG Vibrio cholerae contamination (10 of 38 sample lots positive) and high coliform counts (21 of 33 sample lots in excess of 2400 per 100 grams). NAG V. cholerae contamination was associated with high coliform counts and origin in fresh or brackish waters rather than saltwater.
