Abstract

Background: Bats are potential reservoir hosts for vector-borne
diseases that can transmit many bacterial and viral agents to
humans. Fruit bats are considered reservoirs of many viruses
and they are of major importance in the medical sciences for
controlling and preventing vector-borne diseases. This study
aimed to compare the morphological and genetic differences of
two fruit bat species,
Rousettus aegyptiacus and R. leschenaultii
in Iran, implying anessential need for taxonomic expertise in
applied medical sciences.
Methods: In this experimental study, we collected and identified
26 specimens of bats belonging to two fruit bat species from the
southeast of Iran. The morphological and genetic differences
were characterized between recently recorded migratory fruit
bat
R. leschenaultii and the morphologically similar and resident
R. aegyptiacus. The haplotype network was generated using
the program POPART. The nucleotide variation and population
differentiation were calculated in DNAsp. Furthermore, we
considered additional records of 15 specimens from three
widespread bat species in the north of Iran.
Results: Morphological characterization of two fruit bat
species showed
R. aegyptiacus is larger than R. leschenaultii
in morphometric variables except tail length (TL) for both
sexes. The demographic analyses revealed that all haplotypes
of
R. leschenaulti formed a single haplogroup in the species’
distributional range. In contrast, haplotypes of
R. aegyptiacus
were divided into five haplogroups respecting taxa/localities. The
results represent a strong signature of population expansion for
these two species of bats.
Conclusion: Population of the fruit bats throughout their ranges
in the Middle East may indicate an increased risk of the spread of
viral agents over time. Therefore, precise identification of hosts
and vectors in applied medical sciences is essential to conduct
standard procedures
