BACKGROUND In order to verify the infectivity of rodents with endoparasites in Germi (Dashte-Mogan, Ardabil Province) the current study was undertaken. METHODS Using live traps, 177 rodents were trapped during 2005-2007. In field laboratory, all rodents were bled prior to autopsy, frozen at -20°C, and shipped to the School of Public Health, Tehran University of Medical Sciences, Iran. In para...
Background: Argas persicus has a great importance for health and veterinary, it can transmit many infectious agents such as Borrelia anserina (avian spirochetosis) and Aegyptianella pullorum. Distinguishing Argasidae due to close morphological relationship is difficult. OBJECTIVES: In the present study, we performed molecular analyses based on PCR and sequencing of Amplicon derived from 16S rRN...
Four bats and three rodents species were reported from Farasan Island. Triaenops persicus Dobson, 1871 is for the first time Saudi Arabia based on echolocation calls. The presence of Pipistrellus kuhlii (Kuhl, 1817), Asellia patrizii De Beaux, 1931, Rattus rattus (Linnaeus, 1758), Gerbillus nanus Blanford, 1875 are confirmed.
Species composition, relative abundance, absolute abundance and biomass of sturgeon species were studied during the years 2008-2009. Eighty five stations were covered in the stratified random sampling design in depths less than 1Om using 9m bottom trawl (head line) and in depths more than 10m using 24.7m bottom trawl (head line). More than 70 specimens of Acipenser persicus were caught during t...
Leishmaniosis is a neglected tropical disease which affects several millions of people worldwide. The current drug therapies are expensive and often lack efficacy, mainly due to the development of parasite resistance. Hence, there is an urgent need for new drugs effective against Leishmania infections. As a part of our ongoing study on the phytochemical characterization and biological investiga...
Background Rodents are considered as reservoirs of various zoonotic diseases including helminthic infections. The current study aimed to evaluate the prevalence of helminth infections in rodents, in Boyer-Ahmad district, Southwestern Iran. Methods Overall, 52 rodents were captured from various areas of the district by Sherman live traps. The animals were then euthanized and dissected. During ...
The new genus Pedoniphis gen. nov. (Acari: Mesostigmata: Eviphididae) is described from soil detritus in Sabalan Mountains, northwest Iran, with P. persicus sp. nov. as type species. Among known eviphidid genera, the new genus is the most similar to Scamaphis Karg and Scarabacariphis Mašán and it can be distinguished especially by the dorsal chaetotaxy (setae J2 absent, setae J5 rudimentary) an...
Motility of spermatozoa was studied on 12 and 7 specimens of Acipenser persicus and A. stellatus, respectively. The density measured to be 2.22±0.65x109ml-1 in A. persicus and 2.21±0.55x109ml-1 in A. stellatus. Semen samples were diluted with two extenders containing tris 118mM, sucrose 23.4mM, pH=8, egg yolk (20%), dimethyl sulfoxide (15%) and penicillin potassium (500IU/ml) and biociphus exte...
