new rabies virus variant found during an epizootic in white-nosed coatis from the yucatan february 2008, three white-nosed coatis (nasua narica) were found dead in a recreational park in cancun, mexico. the diagnosis of rabies virus (rabv) infection was confirmed by direct immunofluorescence test. the phylogenetic analysis performed with the complete rabv nucleoprotein gene positioned this isolate close to a sequence of a human rabies case reported during 2008 from oaxaca, mexico, sharing 93% similarity. in turn, these two variants are related to another variant found in rabid tad ...201020392303
ticks and rickettsiae from wildlife in belize, central america.the agents of spotted fevers in latin america are rickettsia rickettsii, r. parkeri, rickettsia sp. strain atlantic rainforest, and r. massiliae. in continental central america, r. rickettsii remains the only known pathogenic tick-borne rickettsia. in the present study, ticks were collected from wild mammals in natural areas of belize. besides providing new data of ticks from belize, we investigated rickettsial infection in some of these ticks. our results provide ticks harboring rickettsial age ...201626831147
the white-nosed coati (nasua narica) is a naturally susceptible definitive host for the zoonotic nematode angiostrongylus costaricensis in costa rica.angiostrongylus costaricensis (strongylida, angiostrongylidae) is a roundworm of rodents, which may cause a severe or fatal zoonosis in several countries of the americas. a single report indicated that the white-nosed coati (nasua narica), acts as a potential free-ranging wildlife reservoir. here we investigated the prevalence and features of a. costaricensis infection in two procyonid species, the white-nosed coati and the raccoon (procyon lotor) from costa rica to better understand their possi ...201627692339
endemic orthopoxvirus circulating in procyonids in serosurveillance studies suggested that orthopoxviruses (opxv) are widespread in the us (e.g., raccoonpox virus, skunkpox virus, volepox virus) and brazil (vaccinia virus); however, their animal reservoir(s) remain unconfirmed. mexican mammal diversity includes several species related to those in which evidence for opxv infections has been found (oryzomys, peromyscus, microtus, and procyonidae). the presence of these groups of mammals in mexico and the evidence of their possible involvem ...201627224209
possible differences in the effects of trypanosoma cruzi on blood cells and serum protein of two wildlife reservoirs.a key step in the dynamics of vector-borne diseases is the role of seasonality. trypanosoma cruzi is a protozoan that causes chagas disease. some wild mammals are considered natural hosts, yet not all mammals show the same response to infection. we explored the effect of t. cruzi on blood parameters in two mammal carnivores, coati (nasua narica) and raccoon (procyon lotor), that were naturally infected in summer and winter seasons. the study was carried out in the zoological park "parque museo d ...201627656956
follow up of natural infection with trypanosoma cruzi in two mammals species, nasua narica and procyon lotor (carnivora: procyonidae): evidence of infection control?a large variety of mammals act as natural reservoirs of trypanosoma cruzi (the causal agent of chagas disease) across the american continent. related issues are infection and parasite burden in these reservoirs, and whether they are able to control t. cruzi infections. these parameters can indicate the real role of mammals as t. cruzi reservoirs and transmitters. here, two species of mammals, white-nosed coati (nasua narica) and raccoon (procyon lotor), were examined for to determine: a) t. cruz ...201425174672
white-nosed coatis (nasua narica) are a potential reservoir of trypanosoma cruzi and other potentially zoonotic pathogens in monteverde, costa rica.we studied white-nosed coatis (nasua narica) in monteverde, costa rica to evaluate their potential as a reservoir for the vector-borne zoonotic parasite trypanosoma cruzi and other selected microorganisms. we live-trapped 20 coatis in july and august 2011 and tested them for t. cruzi by blood smear, molecular analysis of blood, culture of blood and anal gland secretions, and serology. seven coatis (35%) were polymerase-chain-reaction-positive for t. cruzi and one coati was also culture positive. ...201324502732
ticks collected from humans, domestic animals, and wildlife in yucatan, mexico.domestic animals and wildlife play important roles as reservoirs of zoonotic pathogens that are transmitted to humans by ticks. besides their role as vectors of several classes of microorganisms of veterinary and public health relevance, ticks also burden human and animal populations through their obligate blood-feeding habit. it is estimated that in mexico there are around 100 tick species belonging to the ixodidae and argasidae families. information is lacking on tick species that affect human ...201626790745
coral snake mimicry: live snakes not avoided by a mammalian predator.the occurrence of coral snake coloration among unrelated venomous and non-venomous new world snake species has often been explained in terms of warning coloration and mimicry. the idea that snake predators would avoid coral snakes in nature seems widely established and is postulated in many discussions on coral snake mimicry. however, the few workers that have tested a potential aposematic function of the conspicuous colour pattern focused exclusively on behaviour of snake predators towards colo ...199628307444

mange epizootic in white-nosed coatis in western mexico.from november of 1994 to june of 1996 an epizootic of mange, probably caused by the mite notoedres cati, occurred in white-nosed coatis (nasua narica) in the tropical dry forests of the chamela-cuixmala biosphere reserve in western mexico. a monitoring scheme to determine the extent and severity of the epizootic within coatis was implemented. trapping periods and transects were conducted for 2 yr. to control the spread of the disease, all captured infected coatis were either euthanized or treate ...200010682744
prevalence and epitope recognition of anti-trypanosoma cruzi antibodies in two procyonid species: implications for host resistance.more than 180 mammalian species have been found naturally infected with trypanosoma cruzi. many of them play an important role in the maintenance of this parasite. in particular, new studies have appeared which indicate that some species of procyonidae family may play a role as t. cruzi hosts, however, more data are needed to evaluate their long-term physiological response to parasite infection, especially for specific antibodies. in this study, antibodies to t. cruzi were detected and prevalenc ...202032545481
comparative leucocyte populations between two sympatric carnivores (nasua narica and procyon lotor).coatis (nasua narica) and raccoons (procyon lotor) potentially play an important role in zoonotic diseases because they may carry pathogens and can transmit them to humans. to date, our understanding of the immune function of these two carnivores is deficient. the aim of this study was to compare the number of leucocyte subtypes and the phagocytic capacity between the coati and the raccoon. blood samples were collected, and leucocyte subtypes were characterized and counted by flow cytometry and ...201931620288
anatomy of raccoon (procyon lotor) and coati (nasua narica and n. nasua) forearm and leg muscles: relations between fiber length, moment-arm length, and joint-angle excursion.muscle architecture, moment arms, and locomotor movements in the distal limb segments of the procyonids nasua (coati) and procyon (raccoon) are analyzed with reference to patterns of muscle fiber length. this study addresses the hypothesis that relative fiber lengths among muscles in a muscle group can be predicted on the basis of correlates of muscle tension. the results include the following: consistent patterns of fiber length of muscles in a muscle group exist within and between the two gene ...20143973925
pneumocystis and histoplasma infections in wild animals from the amazon region of brazil.routine examination of tissues from wild forest rodents from amapá, north brazil, revealed pneumocystis carinii in lung smears from a newly captured oryzomys capito (cricetidae). acute, fatal infections with this parasite are also recorded in a number of captive "coatimundis", nasua narica (carnivora: procyonidae) and a sloth, bradypus tridactylus (edentata). pneumocystis was also encountered in lung smears from a newly captured and apparently healthy sloth, choloepus didactylus. the presence of ...19751084602
phylogeographic and diversification patterns of the white-nosed coati (nasua narica): evidence for south-to-north colonization of north america.white-nosed coatis (nasua narica) are widely distributed throughout north, central, and south america, but the patterns of temporal and spatial diversification that have contributed to this distribution are unknown. in addition, the biogeographic history of procyonid species in the americas remains contentious. using sequences from three mitochondrial loci (cytochrome b, nahd5 and 16s rrna; 2201 bp) and genotypes from 11 microsatellite loci, we analyzed genetic diversity to determine phylogeogra ...201930468940
