Molecular detection of Anaplasma marginale and Anaplasma ovis in sheep and goat in west highland pasture of Iran

Objective:To determine the prevalence of Anaplasma marginale (A.marginale) and Anaplasma ovis from sheep and goat in different highland pasture in west of lran.Methods:From July 2015 to October 2015,370 blood samples of sheep and goat were collected fiom different regions in Hamedan province,Iran.The DNA extracted fiom blood and subsequently,16S rRNA and MSP4 genes were analyzed by nested-PCR,semi nested-PCR and RFLP methods.Results:In the PCR assessment,overall 27.5％ (102/370) of sheep and goat were positive for Anaplasma ovis and A.margiule infection,which was lower than reports from tropical and subtropical regions of lran.Statistical analysis (the Chi-square test) did not show any significant relation between infection and variables such as location,tick infestation age and sex (P ＞ 0.05).No significant correlation between the altitude and the Anaplasma species infection was found (Mann-Whitney test:P ＞ 0.05).However,Anaplasma infection in goat significantly is more than the sheep (P =0.008).Conclusions:The ecological changes affect the frequency and distribution of Anaplasma species.Furthermore,our results indicate that sheep as potential reservoirs ofA.marginale.

[ relationship between contact with pets and domestic animals and their owners' mental health and personality trait]

Today, many families either have pets or work in animal husbandry units. It is very important to investigate the mental outcomes of animal care and also to study their keepers' personality traits. This study aims to perform a comparative examination of owners' mental health and character specifications or those of animal husbandry units' personnel. In this descriptive study, about 500 people were selected through available sampling technique. They had contact with animals or worked in a husbandry unit in the suburbs of Tehran. After referring to the veterinary clinic of Tehran University, they were studied using a general health questionnaire and an international personality question bank. The collected data were analyzed using SPSS software as well as multivariate and follow-up tests. The results of the present study show that all general mental health sub-scales except for anxiety are different in these groups. However, no difference was observed regarding responsibility and extroversion. Meanwhile, the adaptability of dog owners was lower than that of sheep owners; moreover, cattlemen were more irritable than sheep owners. In sum, the mental health of pet owners of the present study is at a lower level compared to that of those in other countries. It seems that the difference is due to religious and cultural differences existing between the two
