| exposure of feral swine (sus scrofa) in the united states to selected pathogens. | feral swine (sus scrofa) are widely distributed in the united states. in 2011 and 2012, serum samples and tonsils were recovered from 162 and 37 feral swine, respectively, in the us to evaluate exposure to important swine endemic pathogens. antibodies against porcine reproductive and respiratory syndrome virus (prrsv) and porcine circovirus type 2 (pcv2) were found in 2.5% and 25.3% of tested sera, respectively. positive serological reactions against mycoplasma hyopneumoniae and actinobacillus p ... | 0 | 25673913 |
| molecular typing of streptococcus suis isolates from iberian pigs: a comparison with isolates from common intensively-reared commercial pig breeds. | the iberian pig (ip) is a traditional spanish breed variety of the domestic pig (sus scrofa domesticus) with high economic importance because of the value of the dry-cured products in national and international markets. the genetic characteristics of tonsillar and clinical streptococcus suis isolates from the ip maintained under extensive or intensive management conditions were investigated. s. suis isolates from ip pigs were compared with s. suis isolates from intensively-farmed pigs of common ... | 2014 | 25458888 |
| prevalence of streptococcus suis genotypes in wild boars of northwestern germany. | invasive serotype 2 (cps2+) strains of streptococcus suis cause meningitis in pigs and humans. four case reports of s. suis meningitis in hunters suggest transmission of s. suis through the butchering of wild boars. therefore, the objective of this study was to investigate the prevalence of potentially human-pathogenic s. suis strains in wild boars. s. suis was isolated from 92% of all tested tonsils (n=200) from wild boars. a total of 244 s. suis isolates were genotyped using pcr assays for the ... | 2007 | 17085699 |
| streptococcus suis meningitis, a poacher's risk. | streptococcus suis infection is a zoonosis that has been mainly reported in pig-rearing and pork-consuming countries. the most common disease manifestation is meningitis, often associated with cochleovestibular signs. the causative agent is streptococcus suis serotype 2, found as a commensal in the tonsils of its natural host, the pig. persons at risk are mostly those with an occupational exposure to domestic pigs or their meat products. a case of meningitis caused by streptococcus suis in a poa ... | 2000 | 11205632 |
| prevalence of streptococcus suis types 1 and 2 in domestic pigs in australia and new zealand. | using an indirect fluorescent antibody test, 54 per cent of 734 palatine tonsils of conventional pigs slaughtered in australia and new zealand were found to be infected with streptococcus suis type 1 and 73 per cent of 959 were infected with s suis type 2. variations in the prevalence of infection in pigs from different herds were thought to be due to differences in the sample sizes rather than to real differences in the prevalence between herds. the prevalence of infection with s suis was simil ... | 1989 | 2658296 |
