q fever and leptospirosis in the dairy farming community and allied workers of worcestershire.sera collected from dairy farmers, their families and farm workers, slaughtermen, artificial inseminators, veterinarians, and a group of doctors and civil servants with no direct connexion with farming were examined for evidence of q fever or leptospirosis. one thousand and fifty-two sera examined for q fever yielded 26% of positive results with titres of complement-fixing antibody through 1 in 4 to 1 in 128 and over. on the other hand, 876 sera examined for agglutinating antibody to various lep ...19695364436

a new serovar mogdeni of serogroup tarassovi of leptospira interrogans isolated from a sewage plant in england.among 30 strains of leptospires isolated from samples of sewage taken before and during treatment at two sewage plants in england, only one appeared to belong to leptospira interrogans, the species that comprises the leptospires that are pathogenic to man and animals. that strain, compton 746, was isolated from settled sewage, before treatment at a treatment plant that deals mainly with human sewage. it was shown serologically to belong to serogroup tarassovi and appears to represent a new serov ...19873678398
identification by cross-agglutination absorption and restriction endonuclease analysis of leptospires of the pomona serogroup isolated in the united kingdom.five strains of leptospira interrogans isolated in the united kingdom and belonging to the pomona serogroup were subjected to cross-agglutination absorption and bacterial restriction endonuclease dna analysis (brenda) for their identification. british isolates were compared with reference strains representing the known serovars in the pomona serogroup and also with isolates of the pomona serogroup obtained from other countries. three strains isolated from wildlife in england produced equivocal r ...19852999928
leptospiral and hepatitis a antibodies amongst windsurfers and waterskiers in bristol city docks.previous epidemiological studies have detected a substantial risk of gastroenteritis associated with snorkel swimming events in the bristol city docks. the event has since been discontinued. similar risks were not identified at that time for surface-based events. a subsequent fatality from weil's disease (leptospirosis) and a case of hepatitis a associated with surface water immersion in the bristol city docks water prompted this study of leptospiral and hepatitis a immunity amongst regular wind ...19892786228
leptospira interrogans serogroup pomona infections in the uk: is there a real threat for farm animals?current typing of leptospira strains requires a combination of both serological and molecular methods. study of the epidemiology of strains within the pomona serogroup has proved problematic due to the limitations of serological typing methods. this is particularly true of the two main complexes within this group, namely the pomona, monjakov, kennewicki cluster in leptospira interrogans species and the mozdok, tsaratsovo, kunming, altodouro cluster in leptospira kirschneri strains from the south ...201728213528
assessing the impact of tailored biosecurity advice on farmer behaviour and pathogen presence in beef herds in england and wales.the term 'biosecurity' encompasses many measures farmers can take to reduce the risk of pathogen incursion or spread. as the best strategy will vary between settings, veterinarians play an important role in assessing risk and providing advice, but effectiveness requires farmer acceptance and implementation. the aim of this study was to assess the effectiveness of specifically-tailored biosecurity advice packages in reducing endemic pathogen presence on uk beef suckler farms. one hundred and sixt ...201627931934

serological and bacteriological survey of leptospiral infection in pigs in southern england.a total of 597 pigs were examined for serological and bacteriological evidence of leptospiral infection. the sample comprised 189 porkers, 205 baconers and 203 sows. sera were tested against 17 antigens from 16 serogroups and the overall prevalence of titres was 15.7 per cent. the lowest prevalence of titres was found in porkers (10.0 per cent). the highest prevalence of titres to an individual antigen was recorded with bratislava, a member of the australis serogroup, with 12.2 per cent of pigs ...19817323462

infection by leptospires of the pomona serogroup in cattle and pigs in south west england.leptospires belonging to the pomona serogroup were isolated from calves involved in two outbreaks of acute haemolytic disease which were characterised by jaundice, haemoglobinuria and high death rates. retrospective case studies in which serological evidence of pomona serogroup infection was found are also presented. serovar pomona is the leptospire of the pomona serogroup most commonly incriminated in clinical disease in domestic species, but the organisms isolated in this study were antigenica ...19846495570
identification of a reservoir of leptospira interrogans serovar muenchen in voles (microtus agrestis and clethrionomys glareolus) in england.infection with leptospires of the australis serogroup is widespread in voles in southern england and the serovar identification of five randomly-selected isolates was determined by cross agglutination absorption. two isolates from short-tailed voles (microtus agrestis) and three isolates from bank voles (clethrionomys glareolus) were all identified as serovar muenchen. the only previous isolation of this serovar is that from a human in germany.19836372316
benign leptospirosis: first reported outbreak in british isles due to strains belonging to the hebdomadis serogroup of leptospira interrogans.the clinical and epidemiological features associated with the first reported outbreak in the british isles of benign anicteric leptospirosis, due to strains belonging to the hebdomadis subgroup, are described. four cowherdsmen working in two dairy farms in surrey developed a febrile illness which was not associated with jaundice, but aseptic meningitis was a feature. microscopic agglutination tests with formolized antigen suspensions revealed a significant rise in the agglutinin titres against v ...19695812536

the coypu as a rodent reservoir of leptospira infection in great britain.the coypu (myocastor coypus molina) is an aquatic rodent that has become a widespread pest in the south-east of england. since the natural habitat of this animal is aquatic, the possibility of infection with leptospires was investigated. twenty-nine coypu were trapped and examined by serological, histological and cultural methods. of these, there was serological evidence of infection in seven coypus and leptospira interrogans var. wolffii was isolated from a further animal. this appears to be th ...19854067296
