Members of the genus Cryptosporidium are small coccidian protozoan parasites that infect the microvillous region of epithelial cells in the digestive and respiratory tracts of vertebrates. Several species of Cryptosporidium have been described and appear to be specific for a class of vertebrates: C. parvum, C. muris, C. felis, and C. wrairi infect mammals, C. baileyi and C. meleagridis infect birds, C. serpentis infects reptiles, and C. nasorum infects tropical fish.Fecal samples from 200 native  turky randomly selected from 30 regions in Dezful, Iran, were examined to investigate the prevalence of Cryptosporidium infection. Cryptosporidium oocysts were identified by using the Ziehl-Neelsen modified staining technique in 4 of 200 turky . Overall prevalence of infection was 2%, Both sexes of turky were infected with Cryptosporidium parasites, but prevalences were higher in male.  Manuscript profile

Due to the increasing use of pesticides in agriculture and the entry of pollutants into water sources, toxins cause serious problems in aquatics such as fish. The effects of Malathion on liver and kidney were studied in aquarium this toxin is also used in agriculture and easily through the water is flowing into the ponds. In this study, concentrations of pesticides were used in the four treatments; the treatments consisted of a concentration of 0.1, 0.01, 0.001 and control group. There were 20 fish and 30 liters of water per aquarium and all conditions were the same for four aquarium. After 2, 4 and 6 days of liver and kidney were taken pathology samples, Hepatic necrosis, hemorrhage and pathologic hypertrophy was seen in slides, the deterioration in renal proximal and distal tubes and bleeding, degeneration was seen in kidney tubes This study concluded that gold fish were exposed to different sub lethal doses of Malathion may cause necrosis and destruction of cells in vital organs.

Egyptian fruit bats (Rousettus aegyptiacus) is the only species belongs to megachiroptera in Iran, and and their reproduction has not been studied yet in Iran. Due to ecological and economic importance and for conservation and to more identify them, the tissue of prostate gland was studied in this research. For this purpose, six megabats were captured by mist net from Sangtrashan cave (Jahrom - Fars) in spring, summer and fall, and transferred to the laboratory. After anesthesia and dissection of them, prostate gland were removed and weighed. Then they were fixed in formalin10% and by automated tissue processor and sections were prepared (fixation, dehydration, clearing and embedding). The sections were stained with hematoxylin and eosin and mounted by light microscope and micrographs were taken with digital camera. Obtained the micrographs showed that pyramid-shape prostate gland was small and milky, with numerous tubules. There were irregular secretory glands with jelly secretion (clear) and solid exudates which were located in bladder neck. Internal epithelial layer of this gland consists of cuboidal to columnar cells which covered the internal surface of the alveoli. They were secretory in all of sampling times. According to above results, It is expected that this species will be sexually active throughout the year.  Manuscript profile

Department of Biology, Jahrom Branch, Islamic Azad University, Jahrom, Iran Recognition of reproductive system in animals is necessary for their protection. For this purpose, 3 bats (Rossetus aegyptiacus) captured by mist net from Sangtrashan cave (southern Iran) in July and were transferred to laboratory. They were anesthetized, dissected their uterus and weighed. Then they were immersed and fixed in formalin 10%. After 2 weeks, the section with 5 µm thickness, were prepared by tissue processing for histological study. The sections were stained by haematoxylin and eosin and mounted by light microscope. Results showed that uterus was forked andV shape. There was in hips, between bladder and rectum, and was weighing 0.46g. Oviduct (0.38g) with ciliated columnar epithelium, glandular endothelium and vascular myometrium with smooth muscle in two equal horns were seen. Based on these results, uterus in bats, according to the general pattern of mammals spatially primates, and this pattern is suitable for singleton in them. Manuscript profile

Abstract:       Lori’s breed of sheep has an economic importance for Lorestan province. In present study, anatomical and histological aspects of small intestine in this sheep were examined. Small intestine of 10 individual sheep (5 male and 5 female) were evaluated. Histological sections were prepared through H&E, PAS and Alcian blue methods. Mean length of various parts of small intestine, including duodenum, jejunum and ileum were 62/4 Cm, 14/10 m and 28/9 Cm, respectively. Histological observations showed that the shape of mucosal villi differs in various parts of small intestine. In duodenum villi are foliate in shape and toward the ileum they convert to finger-like structures. Number of goblet cells is different in three parts of small intestine but in ileum is more abundant. Deep parts of intestine are rich in mucosal goblet cells. Mucosal glands of small intestine (Brunner's gland) are not limited to duodenum but extended to first part of jejunum. Payer patches are also not confined to ileum and observed in terminal part of jejunum too. Manuscript profile

Abstract     To date, most genetic progress for quantitative traits in livestock has made by selection on phenotype or estimates for breeding values drived from phenotype, without any knowledge of the number of genes that affect the trait or the effects of each gene. In this quantitative genetic approach to genetic improvement, the genetic architecture of interested traits has essentially been treated as a black box. Genetics can measure genotypes with molecular techniques, and then examine directly how genetic variation maps on to phenotypic variation. There are two major types of measured genotype approaches in quantitative genetic: 1- linkage mapping approach that in which the genotypes being measured are used as markers of chromosomal segment. 2- Candidate gene approach which prior knowledge indicates that surveyed loci may be involved in the phenotype of interest. In other words, DNA markers within or near genes whose products are known to be involved in relevant physiological processes and/or development are evaluated for effects on this traits. The objective in this paper is to short review the some of candidate gene for using in new animal breeding programs.  Manuscript profile

Abstract: The genetic disorders of hemoglobin, the most common monogenic diseases, occur at some of their highest frequencies in the developing countries including Iran. Hemoglobinopathies include structural variants of hemoglobin (Hb S, Hb C, HbE…) and thalassemia's which inherited defects in the globin chains synthesis are. Hemoglobin disorders are fairly common in Iran estimated that 0.5 – 1 % of the Iranian population carries the genes for Hb abnormalities such as D, S, G and E. To date, many studies have been conducted in Iran and prevalence rates for hemoglobinopathies have been assessed. The present survey was undertaken to assess the current prevalence and types of hemoglobinopathies in a regional population of Iran with regard to molecular study. Different mutation in α, β globin's genes causes. There is variation in the prevalence of hemoglobinopathies in different regions and ethnic groups of the country. Based on the result of study, the β-chain variants of hemoglobin S are more prevalent in southwestern Iran. Also, α-chain variants of Hb Q-Iran and Hb Setif are prevalent in western Iran. The molecular basis and clinical severity of thalassemia's are extremely heterogeneous among Iranians due to the presence of multiethnic groups in the country. The prevalence rate of β-thalassemia gene in the southern and northern provinces of Iran was higher than the average national rate. The clinical diversity of Hb H disease (similar genotypes with different phenotypes) has been reported in Iran. In this article, we reviewed more than 20 published papers on hemoglobinopathies in Iran.   Manuscript profile
