The present study was arranged to investigate the existence of different species of Nematodes which infect the cattle thorough an examination of 484 faecal samples which were collected randomly from Mosul city and around regions of it, during the period from October 2011 to June 2012 and determination infection severity of them. The total percentage of infection with Nematodes was 23.34%. The significant variations in percentages of infection were recorded according to months of study. The highest percentage was in December 42.10% and the lowest in February at 2.63%. In this study were diagnosed 13 genera of Nematodes, most of them Haemonchus spp. and Ostertagia spp. In the estimation of infection severity with Nematodes, significant variations were showed among the light infection with both of moderate and severe infection and the highest percentage of light has accomplished to 67.25% and the lowest in moderate infection was 11.50%.
This study included diagnosis of some parasitic worms and intestinal protozoa which infected the cattle, through the examination of (325) fecal samples which where collected randomly from the different regions in Mosul city, from the animals in different ages, from October (2011) to March (2012). The total percentage of infection with different species of parasites was (53.53%). The percentages have been influenced through the months of the study. The high percentage of infection appeared in January was (76.66%) and low percentage appeared in February was (23.68%). The high percentage of infection in intestinal protozoa was (60.91%), while the percentage of infection in Nematoda was (49.42%) then the percentage in Trematoda and Cestoda were (17.24%), (1.72%) respectively. In this study has been diagnosed (12) Genera in Nematoda. The infection of Capillaria bovis was the first record in Mosul city, also in this study has been described the adult worm of Toxocara vitulorum which found in the feces of infected calves, that is not mentioned previously in Mosul city. Also has been diagnosed (5) species in Trematoda, the high percentage of infection is Dicrocoelium dendriticum was (8.04%), while by Cestoda the percentage was (1.72%) in one species Moniezia expansa. The results indicated the (5) species by intestinal protozoa which are infected the cattle, the high percentage of infection in Cryptosporidium spp. was (35.05%). The severity of infection with Nematoda was high percentage of inflection in low grade, then severe and moderate grade.
This study was designed to investigate the prevalence of gastrointestinal parasites in domestic turkeys and infection rates of gastrointestinal parasites infesting turkeys and the relationship with their ages. Seventy-one dropping samples were randomly collected from turkeys reared in Erbil city from April 2019 to the end of June 2019. To diagnose the parasites using wet cotton swabs, fifty swab samples were collected from the oral cavity, esophagus, and crop. Coprological examinations of the samples were carried out in the Laboratory of the Parasites/ Veterinary Medicine College / University of Mosul. The results also showed that the total percentage of infection with gastrointestinal parasites was 35.21%. Five nematode species were recorded in Erbil city turkeys, Heterakis gallinarum 28%, Capillaria spp. 24%, Trichostrongylus spp. 16%, Strongyloides avium 12% and Ascaridia galli 4%. Furthermore, Eimeria spp. of intestinal protozoan was diagnosed, with a 48% infection rate. Strongyloides avium larvae were detected in the turkeys' oral cavity swabs, with an infection rate of 4.0%. Results showed higher infection in > 8 weeks ago) (40%), 4 weeks age (30.76%), and 8 weeks age (27.77%). While the result of this indicates significant variations in the infection rates between the age of > 8 weeks and each of the ages of 4 weeks and 8 weeks. The study revealed that the majority of infection was single infection (76%), followed by double infection (16%), and mixed infection (8%).
The current study was conducted to find out the different species of blood parasites that infect pet birds (Melopsittacus undulatus, Carduelis chloris and Carduelis carduelis) and to know the infection rates with these parasites and their relationship with the sex of the bird, by examining (62) blood samples collected from three species of different pet birds in the Erbil city, of both sexes, during October 2019 to July 2021. The current study showed that pet birds were infected with Haemosporidian parasites with a total percentage of 35.48%, and the highest percentage was in the Eurasian goldfinch (Carduelis carduelis) with 41.17%, followed by the greenfinch (Carduelis chloris) with 31.25%, and the lowest rate was in the budgerigar (Melopsittacus undulatus) by 25%. Also, the study showed that the infection rate of Plasmodium spp. and Haemoproteus spp. was 77.27%, and 45.45% respectively. It was noted that there were no significant differences in the infection rates with blood parasites between males and females. While significant differences were recorded in the infection rates with species of blood parasites according to different types of infection, as the single infection recorded the highest infection rate of 77.27%, while the double infection was lower with a rate of 22.72%.
