Liver and lung samples (25 for each) were collected from slaughtered cows and examend bacteriologicaly for the presence of Escherichia coli Eosin-Methylene Blue ( EMB ) and MacConkey agar positive culture (15 from liver and 12 from lung) were produced by cultivation of liver and lung samples Escherichia coli presence was confirmed biochemically in 53.3% of liver isolates and in 33.3% of lung isolates. Enterohemolytic activity was detected in 75%of both liver and lung isolates

ABSTRACT The aim of this study was to determine the minimum active dilution of two standardized type, representative honeys from two bees farm for 7 clinical isolates of coagulates-negative staphylococci. An agar incorporation technique was used to determine the minimum active dilution, with dilution steps for 1% (v/v) honey and 5% (v/v) for sugar syrup .The plates were inoculated with 10 µL spots of cultures of the isolates. the pasture honey inhibited at mean SD3.2± 0.7% (v/v),3.3 ± 0.5% (v/v) for the Manuk honey and 30.9 ± 1.9% (v/v) for the sugar syrup. Typical honeys are about eight times more potent against coagulase-negative staphylococci than bacterial inhibition were due to their osmolarity alone, but also the activity of honey by having its content

Open wounds have lost the barrier that protects tissues from bacterial invasion and allowfor the escape of vital fluids. The purpose of this study is to evaluate the enhancing oftherapeutic effect of Low Level Laser (LLL) and chitosan on the acceleration of openwound healing. Forty two adult rabbits were used. They divided into three equal groups (I,II and III). Wound was produced at the dorsal region by remove all thickness of skin atwidth of 3.5cm and of length 4 cm. Group I was left without treatment, while chitosanpowder and laser therapy were used in group II and III respectively. Results of two groupswere compared with control group. Histpathologicl results at the period of 3, 7, 14, 21 and28 days post operation reflected the presence of large number of fibroblast with formationof new blood vessels, also the collagen fiber become dense and regular in 14 days postoperation in irradiated groups. In 21days there was formation of new and normal epidermalclosed the rupture area of III group.

The main objective of this study is to demonstrate the histopathological changes and the efficacy of ethambutol of treatment mice infected with mycobacterium tuberculosis. Thirty of white Swisrland mice is 6-8 weeks age, weighted 20-25gm were used they were randomly divided into 3 groups contain of 10 animals for each group. - The 1st group (infected animal group) were inoculate.ed with 0.1 ml of bacterial suspension contain 1x108 cfu/ml intraperitonialy. - The 2nd group (group of infected-treated animal) were also infected as the fist group but after 30 day of infection were treated with 0.1 ml of ethambutol was given orally for 1 30 days. - The 3rd group maintained as a control and were inoculated with 1 ml of sterial normal saline intraperitonealy. At 60 day post infection all animals were sacrified and samples from different organs (liver, lungs, kidncys, spleen, intestine) were isolated for that histopathological examination. The result showed sever pathological lesion such as granulomatous lesions in lungs and livers of infected animals, with depletion of white pulp of spleen and conjestion with degenerative changes seen in kidneys and intestine with infiltration of inflammatory cells. While the infected-treated animals show mild or no pathological lesion in their internal organs.

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.
