“…cant mitogene differences (PHA with A and PWM) in lymphocyte cultures of Aotus from Panama (A. zonalis), Colombia (A. griseimembra), and Peru (A. azarae), and these differences Plasmodium falciparum. This differential sensitivity to falciparum infection was also studied by Espinal et al (1984). Blood serum differences between populations were also pointed out by Brumback and Willenborg (1973).…”

“…In the specimens from Meta, the ventral color also extends as far as the elbows and knees to the inside of the arms and legs, and the hair color is pale orange. The gray-neck specimens from Boyacá show a rather dull yellow hair color in the limbs' underside reaching the elbows and knees; the hair coat is long and soft [Espinal et al, 1984].…”

Description of six Colombian karyomorphs is completed through an extensive cytogenetic characterization of 35 Aotus (owl monkeys) specimens. The description of a new karyomorph for Colombian Aotus by chromosome on Q, G, R, and C, sequential banding is included. Pairs of karyomorphs 2 and 3 and 6 and 9 with 2n of 54, and 50, respectively, as well as karyomorphs 7 and 8 with 46 and 58 chromosomes were strongly suspected to represent different species on the grounds of large karyotypic differences. A proposal for a chromosome nomenclature of Aotus karyomorphs that aims to clarify Aotus taxonomy is presented which achieves a precise correspondence of different banding patterns, based on Q, G, R, and C sequential banding and chromosome measurements. Although our contribution is not a universal nomenclature system, unique criteria for chromosome denomination within Aotus karyomorphs are established. Previous systems of chromosome nomenclature have not successfully addressed the nomenclature of chromosomes of the same karyotype. Am. J. Primatol. 44:255–275, 1998. © 1998 Wiley‐Liss, Inc.

“…It is possible that P. canicollis, which is naturally infected with L. chagasi in Northern Colombia, may be a more capable reservoir host than P. semispinosus. This hypothesis is based on the fact that the genetic background at the inter-and intra-species level can influence susceptibility to particular parasites, as has been well established in murine models of Leishmania (Blackwell 1996), and primate models of malaria (Espinal et al 1984, Cooper 1995.…”

The role of Proechimys semispinosus as reservoir of Leishmania (Viannia) Key words: spiny rats -Leishmania -reservoir -experimental infection Spiny rats (Proechimys spp.) are parasitized by a variety of Leishmania species, including L. aristidesi and recognized pathogenic species such as L. guyanensis, L. amazonensis, and L. mexicana s.l. Although these rodents have been incriminated as natural hosts for pathogenic species in several endemic foci in South America, encompassing Brazil, French Guiana, Venezuela and Trinidad (Lainson et al. 1979, WHO 1990, their reservoir role still needs to be established.In Colombia, information on spiny rats and their relationships with both cutaneous and visceral leishmaniasis is fragmentary. P. semispinosus is the most abundant small mammal inhabiting tropical wet forests of the Colombian Pacific coast where cutaneous leishmaniasis is endemic (Weigle et al. 1986, Gonzalez & Alberico 1993. In the Northern region of the country, another species of spiny rat, P. canicollis, is infected with L. chagasi in tropical dry forests and areas of subsistence agriculture where the original forest has been extensively degraded .Incriminating wild animals as Leishmania reservoirs is based on several biological parameters, among which natural infection, population dynamics, and interactions with and infectivity to vectors are of capital importance. In the present study, using an experimental approach, we evaluated the potential role of P. semispinosus as a reservoir of cutaneous leishmaniasis caused by L. (V.) panamensis. Also, we determined the susceptibility of this species to L. (L.) chagasi to evaluate the utility of this rodent as a model of reservoir host that could be utilized in the laboratory. MATERIALS AND METHODSCollection of spiny rats and quarantine -Spiny rats from the Pacific lowlands of Colombia (Tumaco, Nariño; 1°48'N,78°46'W) were captured with National-type traps, after the appropriate permission from the departmental agency for the protection of wild fauna (Corponariño) was obtained. Approximately 100 trapping stations were established in areas of secondary forest, where banana, plantain and cocoa are grown. The traps were baited with plantain, set before dusk, and inspected at dawn. To avoid excessive stress and self-inflicted wounds, the animals were transferred immediately to transport cages of aluminum walls, where access to food and water was provided. Specimens were transported by air to the central laboratory in Cali and quarantined for 8 weeks in the vivarium. An individual coprological analysis was conducted, and an anti-parasitic treatment [ivermectin (Virbamec®), and propoxur (Bolfo®)] was implemented. A blood sample (0.5 ml), drawn by intracardial puncture, was cultured in NNN and Senekjie's media to detect natural infections with Leishmania or Trypanosoma. Serum was collected for detecting antibodies against the same parasites by means of ELISA. Total IgG antibodies were determined in serum (diluted 1:100) using a soluble T. cruzi or L. panamensis
