Molecular Detection and Genotyping of Intestinal Microsporidia from Stray Dogs in Iran.

Background: Microsporidia as one of the most important pathogens in veterinary and agricultural settings, have emerged in immunocompromised patients in Iran. To date, different genotypes have been identified in humans and animals, supporting the possibility of zoonotic zoonosis transmission potential. The aim of this study was to evaluate the distribution of genotypes among overpopulated stray dogs in vicinity of Tehran, the capital city of Iran.

Investigation of the antimicrobial activity of a short cationic peptide against promastigote and amastigote forms of Leishmania major (MHRO/IR/75/ER): An in vitro study.

Cutaneous leishmaniasis is one of the most endemic global health problems in many countries all around the world. Pentavalent antimonial drugs constitute the first line of leishmaniasis treatment; however, resistance to these drugs is a serious problem. Therefore, new therapies with new modes of action are urgently needed.

Detection of small number of Giardia in biological materials prepared from stray dogs.

Giardia lamblia is an intestinal protozoa with intermittent and low shedding especially in dogs, and the detection of Giardia is accompanied with problems such as sampling and diagnostic method. The objective of this study was to detection of Giardia in biological materials with low number of parasite using parasitological and molecular methods, and also to determine whether the examined stray dogs harbor known zoonotic genotype of Giardia. For this aim 85 fecal and duodenal samples were studied from which 1 was positive by Trichrome staining of stool, 4 were positive by staining of duodenal samples.

Temporal and spatial distribution and species diversity of hard ticks (Acari: Ixodidae) in the eastern region of caspian sea.

Ticks are important parasites because of their voracious blood-feeding activity, and being as vectors for various agents of diseases in both human and livestock. This study was conducted in a monthly schedule from October 2014 to December 2015, at 45 study sites in three regions bordering the Caspian Sea, according to the topography including hillside, plain and coastal areas in collecting ticks from the body of sheep. Alfa and Beta biodiversity indices were calculated and compared between the three areas under study.

Ectoparasites of Stray Dogs in Mazandaran, Gilan and Qazvin Provinces, North and Center of Iran.

Background: The aim of the present study was to determine the prevalence of ectoparasite infestations in stray dogs in Mazandaran, Gilan and Qazvin Provinces in fall and winter in 2013(December to March).

Methods: Seventy dogs in 2013, from these Provinces were examined for ectoparasite infestation and diagnosis of them based on parasitological methods and identification keys was done.

Results: The rate of infestation in these areas was 100%, 68.

Identification and characterization of a cathepsin L-like cysteine protease from Rhipicephalus (Boophilus) annulatus.

The tick Rhipicephalus (Boophilus) annulatus is one of the most important ectoparasites of bovines and is responsible for the transmission of different pathogens such as Babesia and Anaplasma. Cysteine proteases are involved in several host-tick interactions including invasion of host tissues, immune evasion, pathogen transmission, embryogenesis and blood digestion. In this study, the gene encoding R.

Isolation of Small Number of Cryptosporidium parvum Oocyst Using Immunochromatography.

Background: Cryptosporidium parvum causes severe gastroenteritis in immunocompromised human and new borne animals. The organism can be transmitted through water. Since small number of C.
