isolation of salmonella enterica and serologic reactivity to leptospira interrogans in opossums (didelphis virginiana) from yucatán, méxico. | the presence of salmonella enterica and serologic evidence of infection by leptospira interrogans, were detected in the opossum didelphis virginiana in a semi-urban locality of the yucatán state, méxico. ninety-one opossums were captured during the period april 1996 and may 1998. from a total of 17 feces samples, four salmonella enterica subsp. enterica serotypes (sandiego, newport, anatum, and minnesota), and one salmonella enterica subsp. arizonae serovar o44:z4,z23:- were isolated. some oposs ... | 2002 | 12219118 |
seroprevalence of and risk factors for leptospiral antibodies among cattle in the state of yucatan, mexico. | sera obtained from cattle in the state of yucatan, mexico, were screened using the microscopic agglutination test against 13 serovars of leptospira interrogans. a total of 62.8% (461/734) cows were positive for one or more serovars. this seroprevalence probably reflects infection because vaccination against leptospirosis has not been practised in yucatan. the most common antibodies detected were those against antigens of serovars hardjo (54.1%) and tarassovi (53.3%). region was the only risk fac ... | 2003 | 14509536 |
serological survey of canine leptospirosis in the tropics of yucatan mexico using two different tests. | blood samples were taken from 400 stray dogs. the microscopic agglutination test (mat) and enzyme-linked immunosorbent assay (elisa) test were implemented using leptospira interrogans serogroups canicola, hardjo, pyrogenes, panama, pomona, tarassovi, icterohaemorrhagiae, gryppotyphosa, wolffi and brastislava. for the elisa test, sonicated antigen from above mentioned cultures was used. a conjugate ap-labeled anti-dog igg antibody was used, the optimal cut-off point of elisa was set at 1.34. conc ... | 2008 | 18299115 |
a cross sectional study of leptospirosis and fetal death in yucatan, mexico. | leptospirosis is a zoonotic disease affecting mainly to low income human population. acute leptospiral infection during pregnancy has been associated with spontaneous abortion and fetal death during the first trimester and the abortion may occur as consequence of systemic failure. | 2016 | 27226658 |
a survey of zoonotic pathogens carried by house mouse and black rat populations in yucatan, mexico. | the house mouse (mus musculus) and the black rat (rattus rattus) are reservoir hosts for zoonotic pathogens, several of which cause neglected tropical diseases (ntds). studies of the prevalence of these ntd-causing zoonotic pathogens, in house mice and black rats from tropical residential areas are scarce. three hundred and two house mice and 161 black rats were trapped in 2013 from two urban neighbourhoods and a rural village in yucatan, mexico, and subsequently tested for trypanosoma cruzi, hy ... | 2017 | 28689507 |
