“…All tick-host associations recorded here had previously been reported elsewhere in Brazil (BARROS-BATTESTI et al, 2006;SARAIVA et al, 2012;SZABÓ et al, 2013;GUGLIELMONE et al, 2014;OLIVEIRA et al, 2014;KRAWCZAK et al, 2016b;MARTINS et al, 2016;, except for records of A. longirostre on Trinomys dimidiatus and B. torquatus. This tick species has wide distribution throughout the Neotropical region, and its adults have commonly been reported parasitizing rodent species, especially of the genus Coendou (BARROS-BATTESTI et al, 2006;NAVA et al, 2010;.…”

Mammals captured in the Serra dos Órgãos National Park (PARNASO) and the Pedra Branca State Park (PBSP) between 2012 and 2015 were examined for the presence of ticks. In total, 140 mammals were examined, and 34 specimens were found to be parasitized by ticks. Didelphis aurita, Akodon montensis and Oligoryzomys nigripes were the species most parasitized. From these specimens, 146 ticks were collected, including 10 larvae. The ticks belonged to eight species: one in the genus Ixodes and seven in the genus Amblyomma. This study reports new associations of ticks and wild mammals in Brazil.

“…The species richness was similar to our study; however, the species composition showed a few differences. Oliveira et al (2012) reported Marmosops incanus (Lund, 1840), Philander frenatus (Olfers, 1818), and Guerlinguetus brasiliensis (Gmelin, 1788), which were not captured in the present study, although the last one was visually recorded in 2001. Moreover, G. microtarsus was captured in the present study, but not in Oliveira et al (2012).…”

“…The lack of correlation between species abundance and richness for the most recent period may also indicate that disturbances in the environment are continuously occurring in spite of both areas are under conservation measures, affecting the small mammal community structure, as discussed hereafter. Another small mammal survey, also carried out in several altitudes of PBSP by Oliveira et al (2012), registered the occurrence of 10 species of wild small mammals from 2005 to 2007, with a similar dominance of D. aurita. The species richness was similar to our study; however, the species composition showed a few differences.…”

ABSTRACT. The Atlantic Forest is one of the most disturbed Brazilian biomes, with 183 out of 298 species of mammals occurring in the state of Rio de Janeiro. In this study, we aimed to characterize the diversity, community structure, and habitat use of small mammals in the FIOCRUZ Atlantic Forest Campus (CFMA), including areas of Pedra Branca State Park (PBSP, subunit Pau da Fome), state of Rio de Janeiro. We also compared species diversity and composition between two moments 15 years apart (2001 and 2012-2015) and analyzed the population dynamics of the marsupial Didelphis aurita (Wied-Neuwied, 1826). Small mammal captures were made in different habitats: sylvatic-urban interface areas near human dwellings, disturbed forest, and preserved forest areas. Five marsupial species and four rodent species were captured in both periods. There was a reduction in species richness and β diversity between the two periods, indicating that disturbances in the environment over the years may have affected the small mammal community structure. The most altered environment showed the greatest species richness and abundance, while the forest areas showed the smallest values, which may be explained by the loss of mammal species, mainly specialist species in forested areas. We identified three groups of species according to habitat preferences: one related to environments with a higher density of vegetation in upper strata -Marmosa paraguayana (Tate, 1931) and Monodelphis americana (Müller, 1776), another related to a higher density in lower forest strata -Akodon cursor (Winge, 1887), and another with no association with the investigated habitat variables -D. aurita and Oligoryzomys nigripes (Olfers, 1818). The small mammal community structure showed a low level of nestedness in both sampling periods. This study is the first report to evaluate the community structure of small mammals in the sylvatic-urban interface area of Pedra Branca State Park, the largest forest reserve within an urban area in Brazil. The surveys indicate that the small mammal diversity was low in both sampling periods and in both areas, and a species loss in the Pau da Fome locality was observed, despite it is a conservation unit. The greater species abundance and richness in the most disturbed areas suggest an increase of factors favoring the occurrence of synanthropic and opportunistic species.

Em 2005 o primeiro caso de Febre Maculosa Brasileira (FMB) foi reconhecido no estado do Rio Grande do Sul (RS), Brasil. Desde então até abril de 2016 doze casos foram confirmados, sendo que quatro destes são autóctones do município de Cerro Largo, área considerada endêmica para a enfermidade riquetsial. Neste mesmo período o RS também notificou 58 casos suspeitos ao Ministério da Saúde. No RS são encontrados dois biomas, Mata Atlântica e Pampa, este último não ocorrendo em outras unidades federativa do país. Até o momento, inexistem estudos relatando a infecção por riquétsias na ixodofauna gaúcha. Desta forma, o presente estudo teve como objetivo pesquisar a infecção de riquétsias do Grupo da Febre Maculosa (GFM) em cães, pequenos mamíferos e carrapatos; através da Reação de Imunofluorescência Indireta (RIFI), qPCR e tentativa de isolamento de riquétsias em cultivo celular dos ixodídeos coletados em área endêmica (Cerro Largo) e áreas não endêmicas nos biomas Pampa e Mata Atlântica no RS. Na sorologia (RIFI), 33,5 % (55/164), 2,9% (1/33), 40% (16/40) dos pequenos mamíferos e 8,3% (3/36), 13,9% (5/36) e 20,4 (28/137) dos cães coletados na Mata Atlântica, Pampa e área endêmica para FMB, respectivamente, foram sororreagentes para pelo menos um dos seis antígenos de riquétsias testados. Oito espécies de carrapatos foram coletadas no local de Mata Atlântica, sendo: Amblyomma aureolatum, Amblyomma brasiliense, Amblyomma incisum, Amblyomma ovale, Haemaphysalis juxtakochi, Ixodes loricatus, Rhipicephalus microplus e Amblyomma yucumense com destaque para esta última que foi descrita como uma espécie nova. Já para o fragmento de Pampa quatro espécies foram encontradas (A. aureolatum, A. ovale, Amblyomma tigrinum e Rhipicephalus sanguineus) e na área endêmica para FMB no RS, coletamos cinco espécies de carrapatos, Amblyomma dubitatum, Amblyomma longirostre, A. ovale, I. loricatus e R. microplus. Detectamos molecularmente pela primeira vez no RS, Candidatus Rickettsia amblyommii em A. longirostre e A. brasiliense, Candidatus Rickettsia andeanae em A. aureolatum e A. tigrinum, Rickettsia bellii em I. loricatus, Rickettsia rhipicephali em A. yucumense e H. juxtakochi, Candidatus Rickettsia asemboensis em pulgas no Brasil e de extrema importância para o conhecimento da epidemiologia da FMB no RS, detectamos Rickettsia sp. cepa Mata Atlântica em A. ovale oriundos de Cerro Largo (área endêmica para FMB no RS). Como primeiros isolamentos de riquétsia para o estado do RS, isolamos R. bellii de I. loricatus coletados na Mata Atlântica e área endêmica para FMB no RS. O presente estudo é pioneiro em relação a investigação comparativa sobre FMB nos biomas Pampa e Mata Atlântica e também o primeiro estudo molecular e isolamento de riquétsias em cultivo celular de amostras coletadas no RS, Brasil.
