Giardia lamblia is a significant intestinal protozoan in humans worldwide, with high incidence of infection in developing countries, particularly among children. Eight assemblages (A to H) have been identified by molecular analysis; A and B are more frequently associated with human infections. Regardless its importance, to the best of our knowledge, this is the first molecular study on assemblages in Giardia lamblia adopted in Zakho district, province of Duhok, Iraq. The present study aimed to determine the giardiasis infection rate and identify the assemblages of Giardia lamblia in children from four areas in Zakho district. Fecal samples were collected, and microscopic examination was done. Genomic DNA was extracted, and assemblage identification was done via amplification of the gdh gene using a semi-nested polymerase chain reaction and restriction fragment length polymorphism. Out of 31 Giardia-positive samples, 23 were successfully amplified through semi-nested PCR. Nineteen isolates (82.60%) were assigned to assemblage B, and four(17.40%) to assemblage A. Assemblage B was identified as belonging to sub-assemblages B11 and B1V, while Assemblage A was identified as sub-assemblages A1 and A11. This study provides insights about Giardia lamblia assemblages in Zakho district, Duhok province, Iraq, and may serve as a beginning step toward understanding the molecular characterization of Giardia in the studied area.

The study involved the estimation of the prevalence of Entamoeba spp. using microscopy and molecular techniques among symptomatic outpatients during April 2021 to March, 2022. Stool samples were collected from 2592 outpatients with amoebiasis symptoms of both sexes and different ages (≤ l to 60). Also, 107 stool samples were taken randomly from asymptomatic individuals and examined microscopically to detect infection with Entamoeba spp. the positive specimens were used for molecular analysis with positive symptomatic samples targeting the 18S rRNA gene by nested PCR. Microscopically 21.68% (562/2592) were positive, for Entamoeba spp. Males showed highest infection rate than females (67.43% vs 32.56%). Ages from 1-10 years showed the highest rate (54.09%), and urban inhabitant had somewhat a higher rate than rural one (58.54% vs 41.45%) which was statistically non-significant(P>0.05). Among asymptomatic individuals, 57% (61/107) were positive for Entamoeba spp. Nested PCR analysis yielded 73% positive samples for Entamoeba spp. with a fragment size of 897 bp. Three fragment sizes were produced, for E. histolytica, E. dispar and E. moshkovskii which were 439, 174 and 553 bps, respectively. Single infection occurred with, E. histolytica in 46%, of symptomatic and 6% of asymptomatic cases, E. dispar in 38% of asymptomatic and 10% of symptomatic cases, E. moshkovskii, reported at very low rate among both groups.

Sarcocystis is an intracellular parasite belonging to the phylum Apicomplexa. More than two hundred species of Sarcocystis are capable of infecting different species of wild and domesticated animals and humans. This study aimed to determine the prevalence of Sarcocystis species and their morphological characteristics in the esophagi muscles of ruminants slaughtered at Zakho abattoir, Zakho City, Kurdistan Region/Iraq. Esophagi muscle specimens’ of 1586 ruminants including, 764 sheep, 569 goats and 253 cattle were examined macroscopically and microscopically from April 2021to March 2022 to determine the prevalence of macroscopic and microscopic sarcocysts. Results revealed a total rate of infection with macrosarcocysts at 18.03 % (286 / 1586), with the highest rate 26.85% (254/946) in local breeds versus 5% (32/640) of imported ones. The highest rate among local breeds 90.91% (10/11) was in cattle, while the highest rate in imported breeds 9.13% (21/230) was among sheep. The overall rate in males was higher than in females. The detected macrosarcocysts relying on morphological characters were assigned as Sarcocystis gigantea, S. moulei, S. medusiformis, S. fusiformis, and S. hirsuta. Histological examination revealed the presence of microsarcocysts in the esophageal muscles of the three hosts which were assigned as S. tenella, S. arieticanis in sheep, S. capracanis in goats and S. bovifelis or S. hominis in cattle. The study results show the widespread of sarcocystosis among ruminants in this region that poses a threat to livestock and humans. This condition necessitates the development of preventive strategies to minimize or eradicate this parasitic infection.

Abstract: In Iraq, Awassi is the most widespread sheep breed of non-European origin. The breed is adapted to a wide range of environmental conditions. Sheep farming, mainly sheep of Awassi breed, represents an essential economic activity of Iraq; however, so far, only very few genetic data exist on this breed. The present study was performed in Biology Department, University of Zakho. A total of 32 blood samples were obtained from Awassi-Iq (Ovis aries) sheep breed in three farms located in Nineveh province, Iraq. Genomic DNA extraction was performed using spin column method. Specific marker (GenBank: NC001942) used for amplifying 550 bps fragments of mitochondrial DNA in PCR assay. The PCR products were separated by electrophoresis on 1.5% agarose gel, visualized by staining with RedSafe dye, and photographed by a digital camera. Ten PCR products were sequenced and compared to sequences from other countries available in NCB1.The main results indicate that Awassi- 1q (Ovis aries) sheep breed shares similarity to both Chines Tibetan sheep breed (Linzhou); Iranian sheep breed (91.37%), to both Iraqi sheep breeds Hamdani; Nima (91.62%) respectively and to Ovis aries AKK- 46 from Turkey (92.35%). However, Awassi-Iq was shown to be monophyletic, out group breed and diverged earlier than related breeds (Turkey, Iran, and China). This study highlights the importance of Mitochondrial DNA analysis in genetic study of sheep breeds.

In Iraq generally and Kurdistan region especially, goats are important resource of meat and milk production. Growth hormone (GH) plays an important role in several biological processes such as reproduction, lactation, metabolism and growth of livestock animals. The objective of this study was to reveal the polymorphism of growth hormone gene (GH) in five goat breeds (Native, Shami, Merzi , Afghani and Wild goat) via PCR-RFLP technique. Two loci on GH gene named GH1 and GH2 polymorphisms were analyzed. . GH1- HaeIII / RFLP showed only two genotypes (AA and AB) in all breeds, with the absence of genotype BB. The genotype frequency was 0.882 for AB and 0.118 for AA genotype respectively; the allelic frequency was 0.492 for A allele and 0.508 for allele B. However, digestion of GH2 by HaeIII was monomorphic. PCR-RFLP could be employed as useful markers, helping goat breeder in selection of goats for high growth performance.

The study was performed on 504 stool samples from infants and children with diarrhea who attended laboratories at Zakho General Hospital, Heevie Pediatric Hospital, Chamisku and Bersive 1 camps, and children who did not have diarrhea in various primary schools in Zakho between August 2021 and the end of July 2022. The study focused on 1 month of age to 15 years old. The collected stool specimens were examined macroscopically followed by microscopic examination using wet mount and concentration methods. The microscopic findings revealed an overall prevalence of Giardia lamblia at a rate of 6.15% (31/504), with slightly but non-significantly higher infection rate in males than in females (6.71% vs. 5.43%). The highest rate of infection was noted in the age group >3-6 years, while the lowest rate was in the age group >12-15 years, which were 11.76% and 1.45%, respectively. The infection rate was also twice as high among rural residents as compared to urban ones (10.34% and 3.32%), respectively. Infants and children who drink tap water had a high infection rate, whereas those drinking bottled water had a lower infection rate (8.05% and 1.92%), respectively. The infection rate was non-significantly higher in families with more than 6 members than in those with less than 6 members (7.06% and 5.22%) respectively. In terms of monthly infection distribution, the highest prevalence was reported in July 11.29%, and the lowest was recorded in February (2.27%). Finally, the statistical analysis revealed a significant relationship between infection and age group, residency, as well as the types of drinking water consumed, but non-significant relationship between infection and gender, number of family members and months of sample collection.

One of the most common mycobiotic in human which colonizing several functional site like skin, mouth, urinary tract, vagina is Candida without causing any infection (Seneviratne, Jin and Samaranayake, 2008) Modification in local environment of the host enhanced candida growth and hence led to candidiasis (Pope and Cole, 2002). Virulence factors of candida as well as immune system of the host switching Candida form harmless commensal to disease causing pathogen (Yang, 2003). Most common virulence factors of candida; Adherence, extracellular hydrolase enzymes while help the candida to adapt to specific anatomical sites. The pathogenesis of Candida species enhanced by phenotypic switching, filamentation and biofilm formation.(Calderone, Fonzi and Fonzi, 2001). Extracellular enzymes such as phospholipases, protease, lipase and haemolysin contributed in the pathogenicity of Candida species. (Silva et al., 2009) Furthermore, the capability of C. albicans to get iron by haemolysin production is essential in its persistence and capability to form infections in the human’s body. Hemolytic activity is one of the virulence factor that facilitate hyphal invasion and disseminate candidiasis. Odds FC. Candida and Candidosis. 2. London, UK: Bailliere Tindall; 1988. The activity of Hemolysin by Candida is enhanced by present of glucose in the blood agar.(Manns, Mosser and Buckley, 1994). Hemolysins production by Candida albicans destroy hemoglobin in erythrocytes and obtain elemental iron. Hence, hemolysins considered as essential virulence factors which make pathogens to survive and persist (Luo et al., 2004).

Fascioliasis is considered as a neglected zoonotic disease of ruminants. This disease is caused by two species of Fasciola (F.) namely Fasciola hepatica and F. gigantica. They are distributed in more than 70 countries except Antarctica, in areas where sheep and cattle are reared (WHO 2016; CDC 2019). This disease was first recorded as early as 2000 BC. Fasciola spp. cause serious pathological effects to livestock (Abbas et al. 2019). The number of infected sheep exceeds 250 million and about 300 million cattle are infected globally with fascioliasis. The disease cause losses exceeding 3.2 billion $ yearly, due to decrease in milk and meat production and an increase in mortality rate in addition to liver condemnation and expenditure of anthelminthic (Hillyer and Apt 1997; Jaja et al. 2017).

The current study was conducted during January to December 2019,in which five districts were selected in various parts of Duhok governorates which differ in their environmental and geographical conditions they included: Duhok city, Zakho, Shelidiza, Aqrah and Bardarash. Each slaughter house was visited once monthly to determine the rate of fascioliasis among domestic animals; cattle, sheep and goats. The infected livers were examined grossly and the bile duct and gall bladder were inspected for the presence of Fasciola species, the work was performed in Parasitology Laboratory, Biology Dept., Faculty of Science, Zakho University. Fascioliasis was diagnosed in 2.0% (195/9757) of total slaughtered livestock, with the highest rate of infection in cattle which was 3.27% (66/2021), followed by sheep 1.76% (122/6932) and the lowest in goats 0.87% (7/804). Slightly higher prevalence rate from positive cases was found in local livestock compared to imported one (2.10% versus 1.88%). According to gender, males showed higher prevalence than females (2.08% versus 1.08%). Regarding Fasciola species, among sheep and goats; the prevalence of F. hepatica was higher than Fasciola gigantica. While among cattle, F. gigantica was the most common species. With respect to parasite burden, the heaviest burden was recorded in 38.46% (20-100 flukes/liver) of slaughtered livestock with the heaviest being in sheep (55.74%), followed by goats (71.43%) while lightest burden was recorded in cattle in 62.12% (1-10 flukes/liver). Most of the liver flukes were recovered from the bile ducts (67.69 %), followed by gall bladder (21.54%) and the least (10.77%) from both the bile ducts and gall bladder.
