| epidemiologic observations on porcine cysticercosis in a rural community of michoacan state, mexico. | the prevalence of and risk factors for taenia solium infection (cysticercosis) in pigs were studied in a rural community in michoacan state, mexico. visual inspection of the tongues of 216 pigs revealed cysticerci in 14 (6.5%). the prevalence was slightly higher in male (10/105) than female pigs (4/110) (p = 0.06) and increased with age (p less than 0.05). the most important risk factors for infection in pigs were access to human feces at a public washing area (p = 0.004), the presence of an ind ... | 1992 | 1502782 |
| identification of antigenic variants of the porcine rubulavirus in sera of field swine and their seroprevalence. | we sampled sera from 1013 non-vaccinated swine from four states in mexico, guanajuato, jalisco, michoacán and the estado de mexico, to analyse anti-porcine rubulavirus antibody titres against three different porcine rubulavirus isolates (pac-4/1993, pac-6/2001, and pac-9/2003) using a hemagglutination inhibition assay. the results revealed that there were antigenic differences among the isolates assessed. in particular, the estimated correlation between the pac-4/1993 and pac-6/2001 (0.50) isola ... | 2011 | 22171991 |
| [biological characterization of three natural isolates of the porcine rubulavirus (mexico)]. | biological characterization of three natural isolates of the porcine rubulavirus (mexico). porcine rubulavirus (porv) produces a neurological and reproductive syndrome in pigs called the blue-eye disease, known only from mexico. several isolates were grouped by the main symptoms presented during outbreaks: a) neurotropic in piglets, (b) broadly neurotropic in piglets and gonadotropic in adults, and (c) gonadotropic in adults. we studied some biological properties of three strains, which fall in ... | 2008 | 19256422 |
| molecular characterization of the hemagglutinin-neuraminidase gene of porcine rubulavirus isolates associated with neurological disorders in fattening and adult pigs. | "blue eye disease" is a viral infection of swine endemic in mexico, which produces fatal encephalitis accompanied by respiratory signs and corneal opacity in suckling piglets. an atypical blue eye disease outbreak presented high rates of neurological signs in fattening and adult pigs from 2000 to 2003. in order to identify the basis of increased neurovirulence, the hemagglutinin-neuraminidase (hn) gene of several porcine rubulavirus isolates were sequenced and compared with that of la piedad mic ... | 2008 | 18031776 |
| epidemiological investigation of taenia solium taeniasis and cysticercosis in a rural village of michoacan state, mexico. | we performed a survey for taeniasis and cysticercosis among persons living in a mexican village where taenia solium infection in pigs was known to be enzootic. a standardized questionnaire was administered in all 577 households to obtain medical histories and information on demographic and environmental factors and on risk factors associated with transmission of infection. serum and/or stool specimens were obtained from 1005 volunteers and examined for cysticercosis antibodies and intestinal par ... | 1994 | 8154000 |
| uptake of porcine rubulavirus (lpmv) by pk-15 cells. | the porcine virus denominated la piedad michoacan virus (lpmv) is a member of the family paramyxoviridae and is the cause of a disease in pigs present only in mexico. the disease is characterized by meningoencephalitis and respiratory distress in young pigs, epididymitis and orchitis in boars, and reproductive failure and abortion in sows. | 2001 | 11578755 |
