| 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 |
| the opossum didelphis virginiana as a synanthropic reservoir of trypanosoma cruzi in dzidzilché, yucatán, méxico. | in méxico, the role of mammals in the transmission cycle of trypanosoma cruzi is poorly known. in the state of yucatán, an endemic area of chagas disease, both didelphis virginiana and d. marsupialis occur sympatrically. however, until now, only the former species had been found infected with t. cruzi. to evaluate the role of d. virginiana in a peridomestic transmission, nine periods of capture-recapture were performed around the village of dzidzilché, yucatán. the sex, age, reproductive status, ... | 2002 | 12219121 |
| infection by rickettsia felis in opossums (didelphis sp.) from yucatan, mexico. | rickettsia felis is an emergent pathogen and the causative agent of a typhus-like rickettsiosis in the americas. its transmission cycle involves fleas as biological vectors (mainly ctenocephalides felis) and multiple domestic and synanthropic mammal hosts. nonetheless, the role of mammals in the cycle of r. felis is not well understood and many efforts are ongoing in different countries of america to clarify it. the present study describes for the first time in mexico the infection of two specie ... | 2016 | 27074326 |
