title: First isolation of Salmonella blockley in Thailand.
abstract: The first isolation of Salmonella blockley in Thailand was found in 2 strains of animal feed samples and 3 strains of chicken feather samples from a private poultry company in 1989. From 1987 to 1992, the number of S. blockley isolates increased and found in various sources. The major sources were the stools of diarrheal patients, mainly children. Another source of S. blockley was frozen chicken meat which increased every year studied. S. blockley isolated from human and other sources showed a high percentage resistance to streptomycin, tetracycline, kanamycin and chloramphenicol and a low percentage resistance to ampicillin and cotrimoxazole. Thus, S. blockley must now be listed as a possible cause of Salmonella food poisoning in Thailand.
