Aims: To predict and validate survival of non-acid adapted Escherichia coli O157 in an environment mimicking the human stomach. Methods and Results: Survival was predicted mathematically from inactivation rates at various, but constant pH values. Pre

Aims: Cattle are a known main reservoir for acid-resistant Escherichia coli O157 and Salmonella enterica serovar Typhimurium DT104. We studied the response of S. Typhimurium DT104 to extreme low pH environments and compared their response to that of

The presence of genes for the production of the three components of the HBL enterotoxin complex and enterotoxin-T in Bacillus cereus was evaluated by PCR tests for strains isolated from milk. In addition enterotoxin production of B. cereus was evalua

In current models for predicting microbial growth, the lag phase duration is expressed as a function of the growth rate of the micro-organism. We observed that in addition to the growth rate (as influenced by incubation temperature and NaCl contents)

SummaryFrom September 1991 until August 1993 an epidemiological study involving 20 Dutch broiler farms was conducted to identify risk factors and risk reducing measures forCampylobacterinfections in broiler flocks.Campylobacterspp. were detected in 6

SUMMARYIn the summer of 1991 a human outbreak of Salmonella enteritidis infection occurred following a barbecue in which about 100 persons were involved. Eggs, supplied by one or more of 10 different layer farms, were the most probable source of the

Transmission routes of Campylobacter spp. in broilers and possibilities for prevention of infections were studied on two Dutch broiler farms. The occurrence of Campylobacter spp. was studied in successive broiler flocks, in the environment of the far

Broiler flocks are frequently infected with Campylobacter jejuni. The origin of the infection is still unclear. The question of whether colonization of flocks results from transmission of C. jejuni from breeder flocks to progeny (vertical transmissio
