Abstract


This study aimed to document the significance of parasites in transmitting zoonotic pathogens from bats to domestic animals and humans. To achieve this, we performed an examination of ten large caves in Fars Province (Iran), which served as bat roosts. Bats were captured using a mist net and identified based on morphological characteristics. The ectoparasites were collected using brushes and preserved in separate vials containing 70% ethyl alcohol. Bats were released after collecting all ectoparasites from their bodies, except 3 bats. The collected ectoparasites were then prepared as slides and identified using a taxonomic key. The results revealed that out of 66 bats examined, 56 individuals were infested by a total of 113 ectoparasites. These included bat flies [Nycteribia kolenatii (22.1%), Paratrichobius sp. (10.6%) and Penicillidia sp. (11.5%)], mites [Macronyssus flavus (55.0%)], and ticks [Ixodes sp. (0.8%)]. Among the bat species, Myotis blythii and Rousettus aegyptiacus exhibited the highest levels of ectoparasite infestation. Three bats from different species were transferred to the lab, dissected, and their feces were centrifuged using the Formalin Detergent method. Several worms, including nematodes [Seuratum sp.] and Cestoda [Hymenolepis rhinopomae], were isolated from their intestines and feces. The identified specimens were properly deposited in the Iranian National Parasitology Museum (University of Tehran). Some of these findings represent new records in Iran. The results indicate a high infestation rate with bat flies showing a wide distribution and high density in the research region. Therefore, further research is recommended to expand our knowledge of bat parasites.

Abstract

The study investigated the roosting patterns of Rose-ringed parakeets (Psittacula krameri) across six locations in the state of Gujarat, India. Roost sites included 383 trees, of which 228 were used for final roosting and 155 served as pre-roosting sites. The study was conducted over a period of four months from 2019 to 2020. A total of 20 different tree species were identified as roost sites, with Ficus benghalensis being the most utilized. Overall, 228 roosting trees, spread across 12 locations, hosted 50,161 parakeets, with the highest concentration occurring in gardens. Tree height and canopy cover significantly correlated with parakeet numbers, with taller trees (>15 m) and those with canopy cover >100 m² supporting the most parakeets. Pearson correlation analysis confirmed these relationships (R²= 0.1661 for height, R²= 0.3610 for canopy cover, both P< 0.01). No significant monthly variation in parakeet numbers was observed. Normalized difference vegetation index (NDVI) values ranged from 0.007 to 0.51, with a mean of 0.16 for roosting sites, suggesting suitable roosting areas are scattered in dense vegetation, predominantly on the city periphery. The study underscores the significance of tree height and canopy cover to parakeet roosting site selection.
