The aim of this study is to determine the effects of boron supplementation in ration of rams on their productive activity and semen quality. For that purpose, twelve rams were divided into two groups (6 rams/ each). Rams of the first control group were fed the basal ration. Concerning the second group (boron group), the rams were fed the basal ration plus 400 mg boric acid (BA) / kg diet as a source of boron. The rams in both groups fed their corresponding ration for 4 months ad libitum. Blood samples were collected monthly throughout the experimental period. Semen samples were collected at the 12th and 16th weeks of the experiment. The results clarified that the serum levels of tetraiodotyrosine (T4) were observed to be elevated significantly (P<0.05) with growing of age in the rams fed B, but they didn't change in the control group. In addition, the semen quality was maintained normal with boronsupplementation as the individual sperm motilities and live/dead sperm cells percentages were similar to control. Also, boronsupplementation didn't induce any adverse effects on the serum levels of Mg when compared to control group. Thus, boronis considered a potential and useful supplement in ration of rams to improve the thyroid activities and didn't induce any adverse effects on either semen quality or serum magnesium level in rams.

Bovine tuberculosis; caused by Mycobacterium bovis,is a zoonotic diseasecausing approximately 6% of total human deaths. Its economic losses are not only a reduction of 10-20% in milk production and weight, but also infertility and condemnation of meat.Many serological tests are applied for detection of tuberculosis. ELISA test has the highest sensitivity and specificity than the other serological tests for the diagnosis of tuberculosis. Several forms of new technology were brought into the diagnostic approach to mycobacterial infection. The aim of this work was to detect bovine tuberculosis by application of different serological tests. Tuberculin skin test was applied on 2650 cattle, only 63(2.4%) were positive. Forty eight (76.2%) of the slaughtered positive animals showed visible lesions (VL) while the other 15 (23.8%) had non-visible lesions (NVL). The bacteriological examination of the 63 samples revealed isolation ofM. bovis from 47 processed samples (74.6%). The results of the immunoassay test have detected 27 out of the tuberculin positive cattle, while the ELISA has detected 34 out of the positive reactor cattle. It was concluded that immunoassay and ELISA tests act as complementary tests for tuberculin skin test especially in anergic cattle.

This work was planned to investigate the bacteria isolated from broiler chickens head suffered from naked eye pathological lesions. Out of 200 examined head lesions, the result revealed that the major pathogens associated with swollen head syndrome (SHS) were Escherichia coli, Streptococcus dysgalactiae and Pseudomonas aeruginosa. Antimicrobial sensitivity pattern against 11 different antimicrobials proved that isolates were resistant to most of the tested antimicrobial agents. PCR was applied on 4 MDR E. coli, 4 S. dysgalactiae and 2 P. aeruginosa for detection of some resistance and virulence genes. The results of E. coli isolates revealed that blaTEM gene was the most prevalent in all isolates (100%) followed by tetA (A), aada1, aada2 and aacC genes. Meanwhile tetA (B) gene was found in 3 (75%), while aadB gene was not detected in any isolates. All S. dysgalactiae proved to harbour 16srRNAgene also all S. dysgalactiae were 100% positive for tuf gene followed by speF gene which found in 2 isolate (50%). The results of PCR of P. aeruginosa isolates revealed that toxA gene was the most prevalent gene found in all isolates (100%) followed by lasI. Then, phzM gene was found in one isolate (50%).

The present study aimed to investigate the efficacy of three natural food supplements (water hyacinth [Eichhorniacrassipes, ''EC''], Yeast [Saccharomyces cerevisiae, ''S. cerevisiae''] and date seeds) on the reproductive and productive activities in male rats. Thus, 40 male albino rats were used and divided equally into 4 groups; Control group (fed normal basal diet), EC supplemented group (400 mg EC / kg body weight), S. cerevisiae supplemented group (120 mg / kg body weight) and date seed supplemented group (0.2 mg / kg body weight). Two months later, all rats were sacrificed and all samples were collected. Results revealed that date seeds supplementation increased significantly the body weight gain. Moreover, date seeds and S. cerevisiae supplementation increased significantly gonadosomatic index, serum levels of total antioxidant capacity decreased serum level of malondialdehyde ''MDA''. On the other side, EC supplementation reduced significantly the studied reproductive parameters as well as it decreased the serum level of TAC and increased the level of MDA. Histopathologicaly, seminiferous tubules appeared with huge amount of spermatids in date seeds group and with moderate number of spermatids in S. cerevisiae group and with few number of spermatids in EC group. Therefore, the present study highly recommends the usage of Saccharomyces cerevisiae as well as date seeds to minimize the ration costs, get the optimal benefit from the natural components of both supplements as well as to induce a higher productive and reproductive performance among animals.

Medicinal herbal feed that used as feed additives are widely applied in livestock production and may be applicable to aquaculture production systems. The present study explores the modulatory effects of incorporation of herbal combination of black cumin seeds (Nigella sativa), peppermint (Mentha piperita) and fennel (Foeniculum vulgare), on African Sharptooth Catfish, Clarias gariepinus. For this purpose, a total of 72 catfish were randomly distributed into 6 groups of 12 fish each and fed on the experimental diets for 45 successive days. Fish of first group were fed on basic diet only while, those of the second one were fed on basic diet supplemented with 0.5% from each medicinal plant while, other 4 groups were subjected to challenge experiment byinjection with Vibrio vulnificus. The third group was kept non-injected, fourth group was injected by saline, fifth and sixth groups were injected by Vibrio vulnificus after feeding with basic diet and basic diet with herbs, respectively. Results proved that, total antioxidant capacity, serum total proteins, albumins and globulins were observed to be significantly higher in the treated group as compared to the control. Lymphocytes percent increased significantly in herbal fed group comparing to the control group while, neutrophils percent decreased significantly. Although serum urea level was not affected by herbal supplement, serum creatinine level was decreased significantly. Body weight gain of C. gariepinus increased significantly after herbal administration. Catfish challenged with a Vibrio vulnificus isolate and received the herbal diet showed less mortality than the control group. Fish fed on the herbal diet exhibited normal histological structure of liver, kidney and spleen. In conclusion, based on the current results together with the low cost and the potential antioxidant and immune effects of mixed herbal medicinal plants used in the study, it is recommended to be used in fish feed to diminish the mortalities caused by some aquatic pathogens.

This study aimed at investigating the physicochemical and bacteriological status of retail-marketed crustaceans in Beni-Suef Governorate, Egypt. Therefore, 120 samples of crustaceans, 60 samples of imported unpeeled shrimp, and 60 samples of locally harvested chilled crab were collected from different fish markets in Beni-Suef Governorate. Collected samples were examined through assessing the physicochemical deterioration criteria in terms of pH and total volatile basic nitrogen (TVB-N), and the bacterial load including mesophilic count, psychrophilic count, Staphylococcus (Staph.) aureus count and most probable number (MPN) of coliforms, faecal coliforms and E. coli. As well as isolation and biochemical identification of pathogenic E. coli and Staph. aureus. The obtained results revealed that high percentages of examined crustaceans had pathogenic E. coli and Staph. aureus, however, total mesophilic, psychrophilic and Staph. aureus counts in most examined crustacean samples lie within the recommended permissible limits by national and international organizations. Similarly, pH and TVB-N mean valwere within acceptable limits. We conclude that crustaceans marketed in Beni-Suef are subjected to inadequate hygienic measures during processing, time/temperature abuse, inappropriate handling and unsatisfactory personnel hygiene.

The present study is an endeavor to explore the relationship between induced hormonal alterations and ovarian activity in female rats. Fifty mature cycling female Albino rats were left for one week for acclimatization and offered balanced diet and water ad libitum. Animals were daily examined by vaginal smears to determine regularity of the estrous cycle. Rats were equally divided into 5 groups; control, hyperglycemic, hypoglycemic, hypercorticosteroid and hypocorticosteroid. At the end of 3 cycles, individual sera were obtained to determine glucose, malondialdehyde (MDA), estradiol and progesterone levels. Moreover, tissue specimens of the ovaries and the Fallopian tube were taken for histopathological examination. Results showed that all hormonal treatments induced alterations in the cellular characteristics of the cycle. Gonadosomaic index (GSI) did not show any remarkable variation. Alloxan or insulin treatments affected significantly serum glucose level in rats as. On the other side, hypercorticism led to marked elevation of glucose while hypocorticism showed no significant effect. Serum MDA showed significant elevation only in hyperglycemic and hypocorticoid groups. Hypoglycemia led to a significant decrease in serum estradiol while other treatments had no effect. Upon progesterone, hypoglycemia resulted in an increased level of the hormone while other treatments led to reduced levels of the hormone. It was evident that abnormalities of the adrenal corticosteroids and / or pancreatic insulin levels are concomitant with irregular estrous cycle as well as ovarian and Fallopian tube alterations which led to deviated gonadal folliculogenesis and steroidogenesis.

The paired submandibular gland plays a critical role in maintaining normal oral biology through the lubricating and antimicrobial actions of produced saliva. In this study, the developmental stages of the submandibular salivary gland of the New Zealand rabbits were investigated. Twenty New-Zealand rabbit fetuses of 11-30 days old were used. Samples of the head region and submandibular salivary glands were histologically stained and examined under a light microscope. Results revealed that the submandibular primordia appeared as bilateral invaginated epithelial buds from the linguo-gingival groove on the 12th day of prenatal life. By the 15th day, the buds deeply grow to form a cord-like structure that ends with compact bulges forming the future primitive acini. The formed cords are then branching to develop the primary glandular ducts by the 17th day, which are canalized on the 18th day. The primitive gland capsule was observed by the 22nd day. The lobulation was recognized and became well developed by the 25th day. Similetanouly, the glandular duct system is completely developed, and serous adenomeres fully occupied the parenchyma and are surrounded by myoepithelial cells. The full-term fetuses have fully developed submandibular glands with a typically compound tubulo-acinar nature and parenchymal seromucoid adenomeres. The PAS staining revealed a strong positive reaction in the striated ducts; however, weak PAS reactions were noticed in the cytoplasm of the acinar cells

This study contains evidence-based recommendations for the prevention of hospital acquired infections. Hospital acquired infections are a major cause of mortality and morbidity and provide challenge to clinicians. Measures of infection control included identifying patients at risk of nosocomial infections. Antiseptics and disinfectants are used extensively in hospitals and other health care settings for a variety of topical and hard-surface applications. In particular, they are an essential part of infection control practices and aid in the prevention of nosocomial infection. This study investigated the nosocomial infection via isolation and identification of bacterial pathogens, the effect of detergents against isolated bacteria, and describes the histopathological tissue changes induced by the isolated bacteria in vivo study. Some bacteria resistant to disinfectants were prevalent and these bacteria had different effects on the human, Different pathological changes were seen experimentally by inoculation of these bacteria in mice.

Milk and dairy products are an important exposure route for organochlorine pesticides (OCPs) to humans. For this reason milk, kareish cheese and yoghurt analyzed for the presence of fourteen organochlorine pesticides namely Alpha HCH, Gamma HCH, Delta HCH, Aldrin, Gamma Chlordane, Endosulfan, Dieldrin, Endrin, , p,p'-DDE, p,p'-DDD, p,p'-DDT and methoxychlor using gas chromatography with electron capture detector (GC-ECD. A total of 90 random samples of raw cow's milk samples and dairy products (30 of each) were collected from 4 districts in Fayoum Governorate (Fayoum, Etssa, senoris and Tamia) during a period from September 2017 to January 2018. The results indicated that 6.60%(6/90) , 5.50%(5/90), 25.55%(23/90), 13.33%(12/9), 11.11%(10/90), 1.11%(1/90), 18.88%(17/90), 8.88%(8/90), 15.55%(14/90), 17.77%(16/90) and 22.22%(20/90) of the examined samples were contaminated with Alpha HCH, Gamma HCH, Delta HCH, Aldrin, Gamma Chlordane, Endosulfan, Dieldrin, Endrin, p,p'-DDE, p,p'-DDD and methoxychlor,respectively. None of the examined samples revealed the presence of Dichlorodiphenyltrichloroethane (p,p'-DDT), Heptachlor and Heptachlor epoxide. Generally the concentrations in the examined samples followed the order of Delta HCH > methoxychlor > Gamma HCH > p,p'-DDD > Dieldrin > Aldrin > Gamma Chlordane > Endosulfan > p,p'-DDE > Endrin > Alpha HCH.
