1. Florivores vertebrados de epífitas vasculares: o caso de uma bromélia
Resumo Acredita-se que a prevenção da herbivoria dos vertebrados é um dos possíveis impulsores da evolução da epífita. A literatura escassa sugere que a herbivora em epífitas está relacionada principalmente ao ataque de insetos as estruturas reprodutivas. Em uma floresta de pinheiros observamos que quase da todas as inflorescências de uma broméli

2. Genetic evidence of enzootic leishmaniasis in a stray canine and Texas mouse from sites in west and central Texas
We detected Leishmania mexicana in skin biopsies taken from a stray canine (Canis familiaris) and Texas mouse (Peromyscus attwateri) at two ecologically disparate sites in west and central Texas using polymerase chain reaction (PCR). A single PCR-positive dog was identified from a sample of 96 stray canines and was collected in a peri-urban area in El Paso C

3. Rickettsia typhi y R. felis en roedores y sus pulgas en Yucatán como posible agente causal de casos febriles indefinidos
Rickettsia typhi is the causal agent of murine typhus; a worldwide zoonotic and vector-borne infectious disease, commonly associated with the presence of domestic and wild rodents. Human cases of murine typhus in the state of Yucatán are frequent. However, there is no evidence of the presence of Rickettsia typhi in mammals or vectors in Yucatán. The presen

4. Nitric oxide production by Peromyscus yucatanicus (Rodentia) infected with Leishmania (Leishmania) mexicana
Peromyscus yucatanicus (Rodentia: Cricetidae) is a primary reservoir of Leishmania (Leishmania) mexicana (Kinetoplastida: Trypanosomatidae). Nitric oxide (NO) generally plays a crucial role in the containment and elimination of Leishmania. The aim of this study was to determine the amount of NO produced by P. yucatanicus infected with L. (L.) mexicana. Subcl

5. Preliminary study towards a novel experimental model to study localized cutaneous leishmaniasis caused bY Leishmania (Leishmania) mexicana
There is not an experimental model of localized cutaneous leishmaniasis (LCL) caused by Leishmania (Leishmania) mexicana. The aim of the present study was to characterize the clinical and histological features of Peromyscus yucatanicus experimentally infected with L. (L.) mexicana. A total of 54 P. yucatanicus (groups of 18) were inoculated with 1x10(6) prom

6. Comparison of small mammal prevalence of Leishmania (Leishmania) mexicana in five foci of cutaneous leishmaniasis in the State of Campeche, Mexico
In the Yucatan Peninsula of Mexico, 95% of the human cases of Cutaneous Leishmaniasis are caused by Leishmania (Leishmania) mexicana with an incidence rate of 5.08 per 100,000 inhabitants. Transmission is limited to the winter months (November to March). One study on wild rodents has incriminated Ototylomys phyllotis and Peromyscus yucatanicus as primary res

7. Hidden heterochromatin: characterization in the Rodentia species Cricetus cricetus, Peromyscus eremicus (Cricetidae) and Praomys tullbergi (Muridae)
The use of in situ restriction endonuclease (RE) (which cleaves DNA at specific sequences) digestion has proven to be a useful technique in improving the dissection of constitutive heterochromatin (CH), and in the understanding of the CH evolution in different genomes. In the present work we describe in detail the CH of the three Rodentia species, Cricetus c

8. Trypanosoma cruzi strains isolated from human, vector, and animal reservoir in the same endemic region in Mexico and typed as T. cruzi I, discrete typing unit 1 exhibit considerable biological diversity
In this study, three strains of Trypanosoma cruzi were isolated at the same time and in the same endemic region in Mexico from a human patient with chronic chagasic cardiomyopathy (RyC-H); vector (Triatoma barberi) (RyC-V); and rodent reservoir (Peromyscus peromyscus) (RyC-R). The three strains were characterized by multilocus enzyme electrophoresis, random

9. Retention of Leishmania (Leishmania) Mexicana in naturally infected rodents from the State of Campeche, Mexico
In the State of Campeche, Mexico, zoonotic cutaneous leishmaniasis is mainly due to Leishmania (L.) mexicana. The parasite population is maintained in a mammalian species, a reservoir in which the ideal course of infection should be long and relatively nonpathogenic. The objective of the present study was to document the retention of L. (L.) mexicana in 29 n

10. Two Persistent Line-1 Lineages in Peromyscus Have Unequal Rates of Evolution
LINE-1, the major family of long, interspersed repeats in the mammalian genome, moves via an RNA intermediate and encodes its own reverse transcriptase. Comparative sequence analysis was used to reconstruct the phylogenetic history of LINE-1 dynamics in the deer mouse, Peromyscus. As is the case in Mus and Rattus, a very small number of active templates prod

11. Efficacy of the urinary bladder for isolation of Borrelia burgdorferi from naturally infected, wild Peromyscus leucopus.
The efficacy of culturing urinary bladder tissue for Borrelia burgdorferi from naturally infected, wild Peromyscus leucopus mice was determined. The urinary bladder cultures were as efficient as spleen, kidney, and blood tissue cultures. The rapid B. burgdorferi isolation (mean, 6 days) from mouse urinary bladders should aid in defining new Lyme disease foci

12. Mys retrotransposons in Peromyscus leucopus and transgenic Mus musculus.
The mys family of retrotransposons exhibits an interesting phylogenetic distribution with 500-1000 copies per haploid genome in the white-footed mouse Peromyscus leucopus and no copies detectable in the house mouse Mus musculus, even though most other repeated sequences are shared by these two species. Comparison of the DNA sequences from the 3' ends of five
