| health assessment and seroepidemiologic survey of potential pathogens in wild antillean manatees (trichechus manatus manatus). | the antillean manatee (trichechus manatus manatus), a subspecies of the west indian manatee, inhabits fresh, brackish, and warm coastal waters distributed along the eastern border of central america, the northern coast of south america, and throughout the wider caribbean region. threatened primarily by human encroachment, poaching, and habitat degradation, antillean manatees are listed as endangered by the international union for the conservation of nature. the impact of disease on population vi ... | 2012 | 22984521 |
| disseminated toxoplasmosis in antillean manatees trichechus manatus manatus from puerto rico. | necropsies were conducted on 4 antillean manatees trichechus manatus manatus that were stranded in single events on the coastal beaches of puerto rico from august 2010 to august 2011. three manatees were emaciated and the gastrointestinal tracts were devoid of digesta. microscopically, all manatees had severe widespread inflammatory lesions of the gastrointestinal tract and heart with intralesional tachyzoites consistent with toxoplasma gondii identified by histological, ultrastructural and immu ... | 2012 | 23135141 |
| toxoplasma gondii, neospora caninum, sarcocystis neurona, and sarcocystis canis-like infections in marine mammals. | toxoplasma gondii, neospora caninum, sarcocystis neurona, and s. canis are related protozoans that can cause mortality in many species of domestic and wild animals. recently, t. gondii and s. neurona were recognized to cause encephalitis in marine mammals. as yet, there is no report of natural exposure of n. caninum in marine mammals. in the present study, antibodies to t. gondii and n. caninum were assayed in sera of several species of marine mammals. for t. gondii, sera were diluted 1:25, 1:50 ... | 2003 | 14580799 |
| serological evidence of toxoplasma gondii infection in captive marine mammals in mexico. | toxoplasma gondii infection in marine mammals is important because they are considered as a sentinel for contamination of seas with t. gondii oocysts, and toxoplasmosis causes mortality in these animals, particularly sea otters. serological evidence of t. gondii infection was determined in 75 captive marine mammals from four facilities in southern and central geographical regions in mexico using the modified agglutination test (mat). antibodies (mat, 1:25 or higher) to t. gondii were found in 55 ... | 2011 | 21944844 |
| disseminated toxoplasmosis toxoplasma gondii in a wild florida manatee trichechus manatus latirostris and seroprevalence in two wild populations. | marine mammals are important indicators for ecosystem health and serve as sentinel species for infectious agents including zoonoses. histological examination of tissues from a stranded florida manatee trichechus manatus latirostris revealed protozoal cysts in the cerebrum and intrahistiocytic tachyzoites in the liver and caudal mesenteric lymph node. disseminated toxoplasma gondii infection was confirmed by immunohistochemistry and sequencing of the nuclear ribosomal internal transcribed spacer ... | 2016 | 27901507 |
| seroprevalence of toxoplasma gondii in captive antillean manatee (trichechus manatus manatus) in brazil. | antillean manatees ( trichechus manatus manatus) are aquatic mammals that inhabit marine waters from central america to the northeastern region of brazil, and they are an endangered species. infection with toxoplasma gondii through intake of water or food contaminated with oocysts has been reported among marine mammals. the present study aimed to evaluate the prevalence of antibodies to t. gondii in west indian manatees living in captivity in northeastern brazil. serum samples from 55 west india ... | 2016 | 27468012 |
