Abstract This study was conducted with the aim to evaluate efficacy of applying 4 different formulations of Beauveria Bassiana (BB) fungus spore to combat Hyalomma ticks. Formulations used included: 1) Distilled water with 2% Tween and BB; 2) Distilled water with 10% cottonseed oil, 0.01% sucrose, 0.2% tween and BB; 3) Distilled water with 10% liquid paraffin, 0.01% sucrose, 0.2% tween and BB, anddistilled water as the control group. Concentration of 1.76×108 was used in preparing formulations. The four prepared formulations were equally sprayed on 128 engorged mature ticks, in 4 groups. Number of dead tick due to spray of formulations were counted in the following days. Treatment effect on mortality of ticks, was assessed using time-survival analysis. 9 days after spraying different formulations, it was found that formulation containing BB fungus had eliminated 50 to 55% of the ticks. Due to the fatality of 55 percent Hyalomma ticks in this research, it can be hoped that in the future with further research, oil suspension containing BB fungus can be used to combat Hyalomma ticks.

Abstract
Balantidium coli is a ciliate intestinal protozoan with a wide host range in vertebrates, e.g. pigs, cattle, chimpanzees, and more rarely, dogs, cats, sheep, horses, and camels. This parasite causes clinical manifestation from asymptomatic to serious dysenteric forms. A total of 200 cattle were randomly selected from traditional farms of Darab city for a period of six month from January 2012 to July 2013. Feacal samples were prepared directly from rectum of these cattle. These samples were transferred to laboratory and were examined for the detection of Balantidium coli after concentration with formal-ether method and trichorme staining. The prevalence of Balantidium coli in the studied samples was 41.5%. The infection rate of Balantidim coli among female and male cattle was 57 (43.2%) and 26 (38.2%) respectively. The highest and lowest prevalence of Balantidium coli was in more than 3 years old cattle (47.6%) and 1 to 3 years old cattle (25.6%) respectively. There was and statistical significant difference between prevalence and age groups (P<0.05). Out of examined samples 12 (6%) were positive for trophozoite, 48 (24%) for cyst and 23 (11.5%) for (cyst & trophozoite). Finally present study revealed that the cattle of Darab city were infected by Balantidium coli. Because of zoonotic important of this protozoan parasite, the measures should be taken to control and prevent this parasite.

The present study was performed to determine the prevalence rate and diversity of Eimeria species among sheep population in Garmsar city, Iran. Faecal samples (approximately 3-5 g) were obtained from the rectums of 400 sheep during four seasons in 2013-2014. The sheep were divided in to three groups (less than 6 months old, 6-12 months old, over 12 months old). Number of oocysts per gram (OPG) of faeces was determined by the standard Mc Master technique and identification of genus and species of oocysts was done on sporulation. The result showed an overall prevalence of (19.7%) for coccidiosis. Seven Species of Eimeria included E. parva, E. ovina, E. crandalis, E. ovinoidalis, E. ahsata, E. intricate and E. weybridgensis were recognized. There was significant difference in the prevalence rate of infection between seasons (P

In this survey, the infection rate of Linguatulaserrata nymphs in mesenteric lymph nodes (MLNs), livers and lungs of 400 cattle was studied in different seasons considering their sex and age in Tabriz abattoir. The lymph nodes, livers and lungs were examined macroscopically. A digestion method was also applied for investigation of liver and lung samples. The infection rate of L. serrata nymphs in MLNs and livers was 17.2% and0.25% respectively. But none of the lung samples were infected. The infection rate in slaughtered cattle significantly increased with age (P0.05).Moreover, there was not any significant difference in infection rate through the different seasons of the year(P>0.05).
