A new species of Gaeolaelaps (Acari, Mesostigmata, Laelapidae) is described based on morphological characters of adult females collected from nest of Formica sp. (Hymenoptera: Formicidae) in the Shahrekord Region, Chaharmahal va Bakhtiari province, Iran. A key for the identification of species of Gaeolaelaps with short peritremes is presented.

As I read the study by Bakhtiari et al. (1), I noticed that they miscalculated the positive predictive value. They indicated that the positive predictive value of the PCR assay was 100%. But when I placed the values on the table and calculated the positive predictive value of the PCR assay, I found it 83.3%.

Infections by protozoan parasite Toxoplasma gondii are prevalent worldwide in animals and human. T. gondii is the causative agent of toxoplasmosis, one of the most prevalent parasitic infections to humans and domestic animals. If first be during pregnancy, T. gondii may be transferred vertically by tachyzoites that are passed to the embryo via the placenta. T. gondii may be transmitted horizont...

Background Genetic factors are candidates for about 30% of male infertility with sperm production-related abnormalities. Y chromosome microdeletions are responsible for around 10% of male infertility. These microdeletions generally occur in azoospermia factor on the Yq. That is often associated with the quantitative reduction of sperm. Objective The aim of this cross-sectional study was to de...

BACKGROUND The present study was carried out to describe the epidemiological aspects of gastrointestinal helminthic infections of canids in Chaharmahal and Bakhtiari Province, the central western part of Iran. METHODS Forty nine canid species including, dogs, jackals, foxes and wolves were included in this study. The contents of their alimentary canal were inspected in order to isolate and id...

This note proposes various axiomatizations of contingency logic under neighborhood semantics. In particular, by defining a suitable canonical neighborhood function, we give sound and complete axiomatizations of monotone contingency logic and regular contingency logic, thereby answering two open questions raised by Bakhtiari, van Ditmarsch, and Hansen. The canonical function is inspired by a fun...

For this study, 24 Bakhtiari sheep were selected and divided into four age groups: 1-10 days, 5-8 months, 1-2 years and 3 years and more. In each age group, six animals (3 each sex) were used. The specimens of eight different skin regions were collected. They were fixed in 10% formaldehyde solution and processed through routine paraffin embedding, cut at 5-7 μ and stained with H&E, Masson trich...
