Background and Hard ticks are the most important vectors of some diseases including babesios, theileriosis, and Crimean–Congo hemorrhagic fever that affect both animals and humans. Among the members of this family, Rhipicephalus bursa is one of the most important vectors of babesios and theileriosis in Iran and around the world. Therefore, detection of abundance and seasonal dynamics of this species can play an important role in better understanding of the epidemiology of the diseases they transmit. A year round sampling of R. bursa was conducted from July 2007 to July 2008 in three topographical areas including: highland, woodland and lowland in Sari, Iran. The seasonal activity, species abundance and frequencies for presence or absence of the species were investigated in two hosts, sheep and cattle. Morisita index was applied to determine the similarity of species abundance in three regions. The results showed that in all study areas the highest activity of tick was observed in spring and summer which decreased to zero in autumn and winter. The highest abundance of R. bursa was found in highland in spring (n=376) and summer (n=352). The highest frequency of tick was recorded in sheep during spring in highland and lowland and during summer in woodland. Similarity index of R. bursa showed woodland and highland as the most similar areas based on species abundance. Compared to cattle, high frequency and infestation rate of R. bursa were observed in sheep flock. Therefore, control programs should be directed more in sheep and preventive measures should be taken in highland during spring and summer.

Pediculosis (Pediculuscapitis)، a parasitic disease، used as an important factor to determine health status of a community. This study was performed to survey the factors concerning with Pediculosis epidemiology among primary-school children of Sari، Mazandaran Province، in 2012-13. 4712 primary school children (boys and girls) were visited for head lice using cluster sampling method. Data was collected by five trained individuals using a questionnaire that included the information on the diagnostic result of head lice، eggs، and nits infections as well as the sex، age، grade، and residence place. Data were analyzed through chi-square test and the confidence level was set at 95%. Out of 4712 primary school children 78 individuals were infected with head lice. The prevalence of infection was calculated as 1. 65%. Significant correlations were observed between prevalence of pediculosis and factors such as bathing facilities، using personal instruments، parents educations، having health care consultant، complying with personal health، and fathers job (p<0. 05); while there was no significant relations between head lice infection and hair shape and student grade (p>0. 05). The results illustrate the role of education and guidance of teachers and parents towards improving personal hygiene and public health and subsequently on reducing the Pediculosiscapitis rate among school students in the regions studied.
