The present study revealed to the record digenetic parasites viz., Lecithocladium bulbolabrum in the small intestine of the black pomfret fishes Parastromateus niger for the first time in Iraq and the Arabian Gulf .

ABSTRACT The present study was performed on 80 samples of frozen fish . The samples were collected from different shops in Basrah city . Listeria spp. Was isolated (13%) of frozen fish , also they were counted in the examined samples. The mean counts were 8.75 x 102 CFU/g. of the fish . L. monocytogenes differentially identified from other Listeria species and could he isolated at (5%) in frozen fish . The drug susceptibility characterization of L. monocytogenes cleared that all isolates (100%) were resistant to Ampicilline and Gentanicine . while the other used antibiotics showed different degrees of antimicrobial sensitivity reactions for streptomycin , Tetracycline , Rifampicine and cefotexim

The present study included the collection of thyroid and parathyroid glands from the abattoirs of middle of Iraq in Summer and Winter seasons 2006-2007. The samples were fixed by 10% formalin and processed by the routine histological techniques, then stained by H and E, PAS and Van Gieson stain, then studied under light microscope. Dimensions were measured by ocular micrometer. Analysis of data was done by T-test. The most striking result declared that the thyroid gland showed no differences in histological characters between both seasons as the buffalo was poor thermoregulator animal. It is tempting to speculate that the thyroid gland provide an adaptive advantage for survival of the buffalo in the nature arid environment. The parafollicular cells (C-cells) were sparse and found singly in the thyroid glands. Flat dark nuclei of myoepithelial cells were recognized around the thyroid follicles. This study was referred to the presence of accessory thyroid gland which contains simple follicular epithelium, and little amount of the colloid. Our current study revealed the presence of internal and external parathyroids. The oxyphilic cells in the internal parathyroid gland were not observed. Note: this work in part of Master Science Thesis, submitted to the College of Veterinary Medicine, Baghdad University.

Proctodeal gland (foam gland) of adult male Asian quail (Coturnix coturnix) was studied microscopically. The study declared firstly the foamy appearance of the male quail proctodeal gland and assure its importance for the sexual activity and its absence from the female quail and its species specificity for only the male quail in comparison to the male turkey. The present work also try to compare functionally between male quail proctodeal gland and other accessory sex glands, such as Cowper's gland and seminal vesicle gland

ABSTRAT The aim of this study is an evaluation of mastectomy for removal of mammary glands tumors of bitches referring to histopathological aspect. During a period of three years extending from March 2007 till March 2010, seventeen bitches were presented to department of surgery-college of veterinary medicine-Baghdad, suffering from mammary glands tumors were treated surgically. Diagnosis of the cases was based on case history, clinical signs, in addition several photographs were taken to denote if there was metastases of the tumor to other organ or not. The definitive diagnosis was confirmed via histopathological examination of tumors biopsies. The surgical operations were done under the effect of general anesthesia represented by a combination of Ketamine–Xylazine preceding by atropine sulfate. All drugs injected I.M. Following surgery secondary health problems were happened in seven animals out of (17 treated cases). Histopathological examination of tumor biopsies obtained from affected glands revealed that the tumor was adenocarcinoma (malignant type). Finally we can concluded that surgery is an effective method to cure the mammary glands tumors in spite of secondary complications in some bitches, which all responds to treatment with the exception of the dead bitch.

In this study , it was aimed to isolate some Bacteria from some pulmonary lesions of various pathological conditions occurring in the lungs of cows. For this aims ,samples of the investigation were obtained through the examination of a total of (660)cows ranging from 3 to 10 years of age were examined for lungs affection during the period from November 2006 to July 2007 .Out of these samples ,(148) lung ,constituting (22.4%)suspected for abnormalities were selected . The encountered pulmonary lesions which found in our study were (148) cases (22.4%), included 11 various type of pulmonary lesions associated with bacterial isolation. Escherichia coli being the most frequently isolated organism and the number of it's isolates was (68), constituting (34.9%) of the overall number of isolates. The various bacterial isolates with different pulmonary lesions are mentioned and it's significance is discussed.

Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE) of Rocky Mountain elk in North America. Recent studies suggest that tissue and blood mineral levels may be valuable in assessing TSE infection in sheep and cattle. The objectives of this study were to examine baseline levels of copper, manganese, magnesium, zinc, selenium, and molybdenum in the brains of Rocky Mountain elk with differing prion genotypes and to assess the association of mineral levels with CWD infection. Elk with leucine at prion position 132 had significantly lower magnesium levels than elk with 2 copies of methionine. Chronic wasting disease-positive elk had significantly lower magnesium than control elk. The incorporation of manganese levels in addition to magnesium significantly refined explanatory ability, even though manganese alone was not significantly associated with CWD. This study demonstrated that mineral analysis may provide an additional disease correlate for assessing CWD risk, particularly in conjunction with genotype.

Toxocariasis is a disease of unspecific clinical manifestations in human beings and some animals forming a condition known as visceral larva migerans. Effective Toxocara canis (T. canis) control should destroy the dormant hypobiotic larvae in the tissues of the reservoir hosts. Embyonated egg antigen is intended to be evaluated in rabbits where15 New Zealand rabbits were divided into 3 groups; immunized group that injected with three doses of T. canis egg antigen (First dose with complete Freund's and two successive doses with incomplete Freund’s adjuvant); control infected group and adjuvant control group. At 30th day from the beginning of the experiment, all groups were infected with 10,000 T. canis embryonated egg. Blood samples were collected periodically for measuring antibodies titer by ELISA. Postmortem and histopathological investigations were done. The efficacy of egg antigen protective immunity was evaluated by; the positive antibody titer, retention of larvae in the liver, hepatic eosinophilic granuloma formation, number of the milky spots on the liver surface and lung resistance to the infection. These parameters were detected obviously in the immunized group than the non immunized ones. Consequently, production of this product is recommended where its preparation is simple, easy, fast and economic and may be used as role of vaccine program against the parasite infection in the susceptible hosts.

Polyvalent clostridial vaccine has been prepared according to L+ dose of C. perfringens type B and D, C. septicum, C. oedematiens, the optical density of C. chauvoei, and flocculation test of C. tetani. The vaccine has been evaluated in guinea pigs, rabbits and sheep. It gave high protective immunity in guinea pigs in challenge test (100% protection), the sera of vaccinated rabbits gave high titers more than the permissible limit. Sera of vaccinated sheep showed high antibody titer and good immune response which revealed that the vaccine able to protect sheep against clostridial diseases. The recent formulation of polyvalent clostridial vaccine is very useful tool for production of highly antigenic multicomponent clostridial vaccine used for control of different clostridial diseases.

The main goal of this study was to evaluate the protective efficacy of living attenuated Salmonella Typhimurium (S. Typhimurium) vaccine in poultry and to evaluate its use in control of salmonella infection in chickens. Oral vaccination of chickens within 36 hours after hatching and after 6 weeks from the first dose induced a strong humoral immune response as measured by ELISA. Challenge test was done with virulent strain of S. Typhimurium. Shedding of S. Typhimurium was detected during the first day, but after 14 days, salmonella could not be detected in the internal organs of vaccinated chickens compared with the non-vaccinated challenged chickens.
