Gastrointestinal digeneans (Platyhelminthes: Trematoda) of horseshoe and vesper bats (Chiroptera: Rhinolophidae and Vespertilionidae) in Serbia

The qualitative and quantitative analyses of the digenean fauna of bats were conducted for the first time in Serbia. The sample comprised of 118 individuals of 12 bat species (Rhinolophus ferrumequinum, Myotis mystacinus, M. alcathoe, M. brandtii, M. oxygnathus, M. myotis, Hypsugo savii, Pipistrellus pipistrellus, P. nathusii, Plecotus auritus, P. austriacus and Nyctalus noctula) collected from 15 sites throughout Serbia. Six digenean species were identified: Lecithodendrium linstowi, Plagiorchis sp., Prosthodendrium longiforme, P. chilostomum, P. parvouterus and Mesotretes peregrinus. The helminths were recorded from 35 individual hosts (29.7 %). The species Lecithodendrium linstowi infected the highest percentage of hosts (19.5 %), with a mean abundance of 4.6. GLM analysis of exploratory factors showed that host species and host sex had a significant influence on parasite load, while locality and host age did not influence parasite abundance. No evidence of zoonotic species was found.Helminthologia (2017), 54(1): 17-2

Valuing Mortgage Insurance Contracts in Emerging Market Economies

We develop a new option-based method for the valuation of mortgage insurance contracts in closed form in an economy where agents are risk neutral. While the proposed valuation method is general and can be used in any market, it may be particularly useful in emerging market economies where other existing methods may be either inappropriate or are too difficult to implement because of the lack of relevant data. As an application, we price a typical Serbian government-backed mortgage insurance contract.
