genetic characterization of highly pathogenic avian influenza (h5n8) virus from domestic ducks, england, november 2014.	genetic sequences of a highly pathogenic avian influenza (h5n8) virus in england have high homology to those detected in mainland europe and asia during 2014. genetic characterization suggests this virus is an avian-adapted virus without specific affinity for zoonoses. spatio-temporal detections of h5n8 imply a role for wild birds in virus spread.	2015	25898126
revival of an old problem: an increase in salmonella enterica serovar typhimurium definitive phage type 8 infections in 2010 in england and northern ireland linked to duck eggs.	summarysalmonella enterica serovar typhimurium definitive phage type (dt) 8 is uncommon in humans in the uk. in july 2010, the health protection agency reported an excess isolation rate of pan-susceptible s. typhimurium dt8 in england and northern ireland. by the end of october, this amounted to 81 laboratory-confirmed human cases for all regions of england and northern ireland in 2010, an increase of 26% and 41% on 2009 and 2008, respectively. descriptive epidemiological investigation found a s ...	2011	21470442
prevalence of campylobacter spp. in raw retail poultry on sale in northern ireland.	a year-long survey of fresh, retail poultry products on sale in northern ireland was undertaken to define the prevalence of campylobacter spp. by using protocols based on iso (standard) 10272-1:2006. incubation at 37 and 42 degrees c was undertaken to increase the diversity of isolates obtained. overall, 652 isolates were identified as campylobacter spp. by using pcr and amplified fragment length polymorphic typing. phenotyping wrongly identified 21% of isolates. prevalences of campylobacter fou ...	2009	19777882
general outbreaks of infectious intestinal disease linked with poultry, england and wales, 1992-1999.	between 1992 and 1999, 1426 foodborne general outbreaks of infectious intestinal disease (iid) were reported to the public health laboratory service communicable disease surveillance centre. a fifth were associated with the consumption of poultry. chicken was implicated in almost three quarters of these outbreaks, turkey in over a fifth and duck in 2% of outbreaks. the organisms most frequently reported were salmonella (30% of outbreaks), clostridium perfringens (21%) and campylobacter (6%). ove ...	2001	11732355

chlamydia infection in ducks: preliminary communication.	chlamydia psittaci was isolated from cloacal swab pools from ducks in processing plants, and from cloacal and conjunctival swab pools from ducks on farms, in a small proportion of the samples examined. these isolates were difficult to passage. this difficulty was partly overcome by the use of emetine as the cell growth inhibitor. the direct complement fixation (cf) test was modified for testing duck sera by using complement at the los dose of 1.5 units. by this method, positive titres were demon ...	1982	7069695
ornithosis in poultry workers.	an outbreak of ornithosis in duck workers in the winter of 1979 and spring of 1980 was discovered by the investigation of a cluster of cases in norfolk. a serological survey showed that 61% of duck workers but only 23% of control poultry workers had chlamydia group antibody titres of greater than or equal to 1:8. altogether 9% of duck workers in the survey had antibody titres greater than or equal to 1:32 and a clinical illness suggestive of ornithosis. the proportions of seropositive tests and ...	1981	6110862
