(Washington State University) Despite the perception that wild birds in farm fields can cause food-borne illness, a WSU study has found little evidence linking birds to E. coli, Salmonella and Campylobacter outbreaks.

This study applied a causal inference approach to data from a multisite study that deployed broadly inclusive diagnostics for numerous high-burden common enteropathogens. Relative risks (RRs) of infection with each pathogen during a flooding disaster that occurred at one of the sites—Loreto, Peru—were calculated from generalized linear models using a comparative interrupted time series framework with the other sites as a comparison group and adjusting for background seasonality. During the early period of the flood, increased risk of heat-stable enterotoxigenic E. coli (ST-ETEC) was identified (RR = 1.7...

Conclusion: Molecular typing confirmed that most of the cases belonged to a clonal cluster supporting the hypothesis of a common source; however, the source was not identified. This was the first recognized Campylobacteriosis outbreak in China among 20 years.

In response to anoutbreak of multi-drug resistant Campylobacter infections associated with the purchase of puppies from pet stores, the Massachusetts Department of Public Health has issued a temporary, four-month ban on the sale of all animals by pet stores throughout the Commonwealth.The CDC concluded that the outbreak is being caused by puppies sold by pet stores based on the finding that 88% of the case patients reported contact with a puppy and 71% of these reported contact with a puppy from a pet store.The CDC conclusion is as follows: " Epidemiologic and laboratory evidence indicate that contact with puppies, es...

(CNN) — Puppies: cute balls of fur. But according to the Centers for Disease Control and Prevention, they’re also linked to a multi-state outbreak of an infection that’s resistant to multiple drugs. An outbreak strain of Campylobacter jejuni has been reported in 13 states and so far 30 people have been infected, the CDC said. Four have been hospitalized but no deaths have been reported, the center said. “Epidemiologic and laboratory evidence indicate that puppies purchased from pet stores are the likely source of this outbreak. Many of the cases had contact with puppies or were employees at pet stor...

ConclusionThe comparison of Illumina MiSeq, PacBio and MinION sequencing and analyses with different assembly tools enabled us to reconstruct a complete chromosome as well as a circular plasmid sequence of theC. jejuni strain BfR-CA-14430. Illumina short-read sequencing in combination with either PacBio or MinION can substantially improve the quality of the complete chromosome and epichromosomal elements on the level of mismatches and insertions/deletions, depending on the assembly program used.

eim R Abstract During June 2019, an outbreak of campylobacteriosis occurred in Askøy, an island northwest of Bergen, Norway. According to the publicly available records, over 2000 residents fell ill and 76 were hospitalised, and two deaths were suspected to be associated with Campylobacter infection. By investigating the epidemic pattern and scope, an old caved drinking water holding pool was identified that had been faecally contaminated as indicated by the presence of Escherichia coli (E. coli). Furthermore, Campylobacter bacteria were found at several points in the water distribution system. In the escal...
