Abstract

SEGOVIA H, Karen et al. Prevalence of paramyxoviruses in bats in six areas of Madre de Dios and Puno, Peru with two levels of anthropogenic disturbance. Rev. investig. vet. Perú [online]. 2016, vol.27, n.2, pp.241-251. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v27i2.11640.

The tropical Andes, comprising the Madre de Dios region, are a hotspot for biodiversity conservation. Recent development of the area through paving of the interoceanic highway (IOH) resulted in anthropogenic impacts in the region. This study aimed to identify the prevalence of emerging pathogens of public and animal health importance such as Paramyxoviruses among bats trapped along areas of IOH with different ecological impacts. Samples from six study sites along the IOH were collected from October 2009 to October 2010: three highly disturbed areas and three areas with low disturbance. A site located at the Tambopata National Reserve was selected as an undisturbed environment for control. Bat spleens were tested for Paramyxoviruses by nested PCR targeting the conserved motifs of the polymerase gene. A total of 436 bats from 24 different genera were captured, of which 45 (10.32%; CI 95%: 7.6-13.6%) were positive for Paramyxoviruses. The prevalence was higher in areas with more disturbance than in mildlydisturbed areas(15.7 vs.5.6%,p=0.009).Theprevalencein thecontrolarea was 8.3%. The species Artibeus planirostris showed the highest infection frequency (37%, 17/45). Three positive bats were adults of the Sturnira lilium species collected from one location in Iberia District. Sequence analysis placed these viruses in the Rubulavirus genera (Mapuera virus). The remaining viruses were related to an unclassified Morbillivirus found in bat samples in Brazil during 2013
