infection by trypanosoma cruzi in mammals in yucatan, mexico: a serological and parasitological study.in order to determine trypanosoma cruzi infection among mammals in yucatan, mexico, 372 animals, both wild and synanthropic including carnivores, marsupials and rodents were studied. serological studies by indirect haemagglutination (iha) were carried out to detect antibodies to t. cruzi and a parasitological study was also performed (blood smear and histopathology). of all the animals tested 18.54% were serologically positive, with a significantly higher frequency among the wild ones (33.33%) c ...19969216111
infection levels of intestinal helminths in two commensal rodent species from rural households in yucatan, mexico.the aim of the present study was to calculate the prevalence and intensity of intestinal helminths in the house mouse (mus musculus) and the black rat (rattus rattus) trapped in rural households of yucatan, mexico. sampling was conducted during the rainy season from october to december 2011 and the dry season from january to march 2012. a total of 154 m. musculus and 46 r. rattus were examined, with 84.2% of m. musculus being infected with helminths compared with a significantly lower prevalence ...201524000977
identification of bartonella species isolated from rodents from yucatan, mexico, and isolation of bartonella vinsonii subsp. yucatanensis subsp. nov.bartonella species are highly endemic among wild rodents in many parts of the world. blood and/or blood clot cultures from 38 rodents, including 27 yucatan deer mouse (peromyscus yucatanicus), 7 gaumer's spiny pocket mouse (heteromys gaumeri), 2 black rats (rattus rattus) and 2 big-eared climbing rats (ototylomys phyllotis) captured near merida, yucatan, mexico, led to the isolation in 3-4 days of small gram-negative bacilli, which were identified as bartonella spp. based on colony morphology. d ...201627626126
the occurrence of the larval cestode cysticercus fasciolaris in rodent populations from the cuxtal ecological reserve, yucatan, mexico.cysticercus fasciolaris is the larval stage of the cestode taenia taeniaeformis, whose definitive hosts are mainly cats. this larval stage uses a wide variety of small rodents, and occasionally birds and humans, as intermediate hosts. in the yucatan, there are no reports of the presence of this cestode in animal populations. the aim of this study was to evaluate the occurrence of c. fasciolaris in rodent populations from the cuxtal ecological reserve, yucatan, mexico. trapping of rodents was con ...201121208511
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 ...201728689507
