“…Some of the associated organisms are Toxoplasma gondii [25][26][27], Leishmania spp. [28,29], Trypanosoma cruzi [30,31], and Echinococcus oligarthrus [32]. However, clinical cases of bacterial diseases have been rarely reported.…”

The agouti (Dasyprocta leporina) is a neotropical rodent which has the potential to be domesticated. As such, some research studies have been done on the biology of this animal. Recently, these animals are being kept in captivity as a source of animal protein. Animals which are kept in captivity may present diseases that would not have been reported in the wild due to lack of observation or the lack of occurrence. The aim of this short communication is to report a case of systemic bacterial infection that affected the lungs and liver of a captive agouti. Bacterial analysis revealed that the infection was caused by Escherichia coli. Bacterial infections have been reported in the mammary tissue as well as the skin of the agouti, but to the authors’ knowledge, this is the first report of systemic infection in the agouti affecting several organs. This case was seen in a nine-month-old male agouti that was being housed at the University of the West Indies Field Station (UWI, UFS). The animal showed no apparent sign of disease except for lethargy and subsequently died before any treatment was administered. These findings showed that the agouti may have been under some stress (nutritional or environmental) which predisposed this animal to this infection. Future work has to address the nutritional requirements for the growing agouti as well as some treatment options for managements of similar cases in the future.

“…Species belonging to Trypanosoma have been recorded in the Nhecolandia subregion of Pantanal for the last two decades parasitizing several species of wild mammals and invertebrate hosts [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. These studies indicate that the maintenance of trypanosome species includes several species of wild mammals with different infective competencies in complex, unpredictable, and multivariate wild cycles linked to the various interactions between host species and land use [ 14 , 15 , 20 ]. Despite this effort, the diversity of Kinetoplastea may be higher in the region since Santos et al [ 20 ] observed that some uncharacterized flagellates, detected by hemoculture from three species of small mammals ( Clyomys laticeps , Cerradomys scotti and Monodelphis domestica ), were unable to spontaneously grow and be isolated.…”

Kinetoplastid Species Maintained by a Small Mammal Community in the Pantanal Biome

Kinetoplastids include species economically important in agriculture, livestock, and human health. We evaluated the richness of kinetoplastids that infect small mammals in patches of unflooded forests in the Pantanal biome, an area where we hypothesize that its diversity is higher than currently recognized. Hemocultures (HC) and Next Generation Sequencing (NGS) targeting the 18S rDNA gene were employed for the detection of kinetoplastids. We grouped the positive samples into pools for each small mammal species (Monodelphis domestica, Thylamys macrurus, Oecomys mamorae, Thrichomys fosteri, Clyomys laticeps, and Holochilus chacaris). Eight parasite species were identified: Leishmania amazonensis, L. infantum; Trypanosoma cascavelli (HC + NGS), T. cruzi, T. lainsoni, T. rangeli (HC + NGS), Trypanosoma sp. DID, and Neobodo sp. The use of a tool as sensitive as NGS has increased our awareness of the diversity of kinetoplastids, as well as their host range, with emphasis on the species O. mamorae (seven kinetoplastid species, excepting T. cascavelli in a pool of nine individuals) and T. macrurus (four kinetoplastid species in a single individual). Furthermore, L. infantum and L. amazonensis infections were described in small mammals from this region for the first time. These findings make it mandatory to revisit the kinetoplastids/host associations proposed so far.

Molecular detection and phylogenetic analysis of Trypanosoma spp. in Neotropical primates from Rio de Janeiro State, Brazil

et al. 2022

Trypanosoma spp. infection is a problem in many tropical countries, infecting several animal species, including humans. The aim of the present study was to identify the Trypanosoma species in Neotropical primates from Rio de Janeiro state and compare the results with other reports both phylogenetically and geographically. Molecular detection was based on the 18 SSU gene. The sequences obtained in the PCR were sequenced and compared with others previously deposited in GenBank. These sequences were used to perform phylogenetic analysis and make a distribution map of primate species infected by Trypanosoma species in Brazil. Among 34 monkeys, five capuchin monkeys (Sapajus spp.) and one marmoset (Callithrix spp.) showed Trypanosoma spp. sequences in the same clade of Trypanosoma minasense and three capuchin monkeys’ sequences were in the same clade of Trypanosoma cruzi. The Atlantic Forest and the Brazilian Amazon are the regions with the highest frequency of studies about Trypanosoma spp. and variety of Neotropical primate hosts. These are areas that deserve attention regarding the conservation of biodiversity, but it also makes evident the lack of studies with Neotropical primates in other regions of the country, as well as multidisciplinary studies to better understand the host pathogen relationships.
