| plurality of leptospira strains on slaughtered animals suggest a broader concept of adaptability of leptospires to cattle. | leptospirosis in bovines is in majority determined by the host-adapted serovars, mainly hardjo (types hardjoprajitno and hardjobovis), that belong to the serogroup sejroe. members of other serogroups as pomona and tarassovi have been eventually reported, mainly when outbreaks occurs. nevertheless, the real role of other strains (non-hardjo) on determining disease or being transmitted by cattle free of apparent clinical signs of acute infection remains to be elucidated. in that context, the aim o ... | 2017 | 28472618 |
| molecular analysis of leptospires from serogroup sejroe obtained from asymptomatic cattle in rio de janeiro - brazil reveals genetic proximity to serovar guaricura. | bovine leptospirosis causes substantial reproductive failure in cattle, mainly due to infections with serovar (sv) hardjo infection. notwithstanding, other serovars from the serogroup (sg) sejroe could also have important roles in bovine leptospirosis. the objective was to investigate genetic diversity of serogroup sejroe isolates obtained from asymptomatic cattle in the state of rio de janeiro, brazil. urine and vaginal fluid (vf) were collected from clinically healthy cattle immediately after ... | 2016 | 27033941 |
