Sarcocystis is one of the most important and common protozoan parasites in the world. Various species of Sarcocystis reported in groups of mammals, birds and reptiles. In the life cycle of these parasite there are 2 hosts including hunted and hunter. Usually, omnivores and herbivores, as intermediate hosts (hunted) and carnivores, are considered as the definitive host (hunter) of this parasite. This research for the first time examines the contamination of Sarcocystis (microcyst) in native birds of Mazandaran province (Amol city). For this purpose, randomly, 57 native bird's breast muscles which include 18 pieces of native ducks and 39 native chickens were tested by digestion method. The results of the experiment showed that 55 cases (96.5%) were infected with Sarcocystis bradyzoite that contributed 100% to the local duck and 94.78% to the native species. Based on age groups, the percentage of infection in the group age under 6 months was 80%, in the age between 6 months and one year was 97.91% and in the age group over one year, was 100%. The Chi-square test did not show a significant difference in the percentage of infection between two types of birds (duck-chicken) and age groups (P <0.05).
This study evaluates external parasites in domestic dogs referred to veterinary clinics of Mazandaran Province (Northern Iran). The results of this study show that 110 Dogs (36.6%) infected with external parasites than among 52 Dogs (17.3%) infected with Rhipicephalus bursa. 41 dogs (13.6%) infected with Ctenocephalides canis and 17 dogs (5.6%) infected with both of Rhipicephalus bursa and Ctenocephalides canis. Considering the importance of external parasitic infection in domestic animals and the issue of public health, necessity of hygiene, prevention and control of these factors are very important.
