This study was designed to determine the prevalence of enterotoxigenic S. aureus in table eggs in El-Fayoum city, Egypt. A total of 250 table egg samples (75 Baladi hens’, 75 white farm hens’, 75 brown farm hens’ and 25 duck egg samples) were collected randomly from poultry farms, groceries, supermarkets, and street vendors in El-Fayoum city, Egypt. Each Baladi hen ҆s egg sample was represented by five eggs, while each farm hen ҆s and duck egg sample was represented by three eggs. The shells and contents of eggs were examined for the presence of Staphylococcus spp < /em>., coagulase (coa), and staphylococcal enterotoxins (Ses) genes. The obtained results revealed that the examined samples of shells and contents of Baladi hens ҆, poultry farms ҆ (white and brown), and ducks ҆ eggs were contaminated with Staphylococcus spp. with incidences of 24.0, 9.3, 5.3, 44.0, 8.0, 2.7, 1.3 and 12.0 %, respectively and coagulase-positive S. aureus with the incidences of 16.7, 14.3, 0.0, 18.2, 0.0, 0.0, 0.0 and 33.3 %, respectively. Enterotoxin profiling by PCR proved that two classical enterotoxin genes (Seb and Sed) were produced from three (42.86%) coagulase-positive S. aureus strains, as two Baladi hens’ ҆ eggshells produced Seb and one of the ducks ҆ egg contents produced Sed. The public health hazards of the isolated strains and enterotoxins had been discussed.

Brucellosis is a major constraint to livestock production that still enzootic in livestock in many developing countries including Egypt. This study was conducted with the general objective of establishing the bacteriological status of bovine brucellosis in 15 governorates in Egypt during 2020-2021 to determine the circulating Brucella species on bacteriological and molecular basis. Clinical samples collected included milk or udder secretions, vaginal discharges, fetal membranes and stomach contents of aborted fetuses from dairy cows with history of brucellosis. In addition, lymph nodes (retropharyngeal, prescapular, prefemoral, internal iliac and supramammary) from carcasses of serologically positive animals were obtained from different localities for isolation and identification of Brucella organisms. A total of 136 Brucella isolates were recovered from cattle in different governorates, Egypt. These include, 107 isolates of Brucella melitensis biovar 3 identified on bacteriological and molecular basis from Aswan, Beheira, Beni Suef, Dakahlia, Damietta, Fayoum, Gharbia, Giza, Ismailia, Kafr El-Sheikh, Luxor, Monufia, Port Said, Qalyubia and Sharqia governorates. On the other hand, 29 Brucella abortus biovar 1 isolates were recovered from cattle from Beni Suef, Dakahlia, Damietta, Kafr El-Sheikh, Monufia, Port Said and Sharqia governorates. Molecular identification using primer sequences targeting IS711 gene confirmed Brucella on genus level. Multiplex PCR has amplified four fragments of 450bp, 587 bp, 1071 bp, and1682 bp characteristic for B. melitensis biovar 3, and three fragments of 450bp, 587 bp, and 1682 bp for B. abortus biovar 1. The identification of Brucella spp. in different farm animals of 15 Egyptian governorates highlights the dynamics and role of cattle in dissemination of Brucella infection all over the country. The obtained results indicate that the actual Brucellosis status during the years 2020 and 2021 refers to that B. melitensis biovar 3 and B. abortus biovar 1 are the prevalent types circulating in different Egyptian governorates.

The appearance of the udder varies greatly depending on maturity and functionstatus as well as on individual and breed characteristic sometimes weighing as much as60 Kg in many dairy cows it is extremely large in particular the size, shape and positionof the teats do have a practical importance in determining the suitability of the udder tohand or machine milking , five udder of cattle were taken , aged between (2-5) yearsfrom a local slaughterhouse , the skin was removed , we examined and described theouter anatomy ,these sample were fixed in 10% formalin solution , and processed by theroutine histological technique then studies under light microscope .The udder consists of four separated glands suspended of medial and lateralcollagens lamina, the medial lamina is more elastic than lateral lamina, the medial laminaare more collagenous and originate from the sub pelvic tendon. The lateral lamina ismultiple, the teat is long and cylindrical in shape and the wall is thick.The anatomical study showed that the udder was divided into four identicalquarters with the four main nipples and the additional nipples sometimes associated withthe glandular tissue, the glandular tissue covered by connective tissue that extends insideand covers the whole gland and is described as the hanging system. It consists from themedial and the lateral ligaments, The aim of histological study of the udder in cattle tounderstand the comparative nomenclature and to know the surgical anatomy of thebovine teat , the layers of the wall ,the vascular patron , the distribution of smooth muscles , the annular fold , the vascular patron and the venous circle surrounding thebase of the teat to appreciate the protective function of the teat canal as well as thepattern of intra udder duct system were studies to obtain more details information aboutthe udder value in production of milk and healthy udder are essential to the secretion ofmilk that wholesome to drink and sufficient in quantity to be profitable to dairymen , Thesubstance of the udder consist of gland parenchyma and connective tissue intermingled inproportion that can sometimes be estimated by palpation through the skin, annular fold aconstriction between glandular and teat parts of the milk sinus, it consist of muscularfibers, connective tissue and circular venous channels (Furstenberg&rsquo;s rosette) fold of teatcanal mucosa that extends into the teat sinus .

Diabetes mellitus (DM) is a metabolic disease involving improperly high blood glucose level, hyperlipidemia and hypoinsulinemia. The aim of current study is to assess and compare the influence of&nbsp;Quercus infectoria&nbsp;galls (QIg)&nbsp;extract&nbsp;and glimepiride on pancreatic &beta;-cells secretory function and serum lipid profile in diabetic rats. In the present study, thirty six male rats were used and divided into six groups (n=6), including negative control, STZ induced diabetic control, treated diabetic rats with glimepiride (200mg/Kg Bw), and treated diabetic rats with different concentrations QIg extract, 200 mg, 400 mg and 800 mg/Kg Bw for 42 days, respectively. At the end of the experiment, all rats were fasted overnight, blood samples were collected for measuring fasting blood glucose, insulin hormone and lipid profile. All rats were then scarified by using chloroform in order to take part of the pancreatic tissue. The results show a significant decrease in blood glucose, total cholesterol, triglycerides, low density lipoprotein, very low-density lipoprotein, HbA1c% with obvious elevation in serum insulin hormone and high-density lipoprotein in diabetic rats treated with QIg extract and glimepiride compared with diabetic untreated group. In addition, high atherogenic index in diabetic rats was significantly reduced by different concentrations of QIg extract and glimepiride. Histopathogical results revealed that there was a significant and dose-dependent morphological restoration in the pancreatic structure damages especially at high dose of the extract. These findings provide a new insight into the role of QIg methanolic extract in maintaining normal blood glucose and adequate pancreatic insulin hormone secretion in diabetic rats, amelioration of dyslipidemia and associated cardiovascular alterations with subsequent improvement in pancreatic structural damages in diabetic rats.

Grape seed extraction has many beneficial effects on the cardiovascular system and blood pressure and has also been proven to have anti-obesity effects and/or improve fatty acid oxidation and insulin responses. The objective of this study is to evaluate the effectiveness of grape seed extract on some physiological parameters in multiple systems. To this end, male mice were injected intraperitoneally with (100 mg/kg B.W) for 7 days. Serum was collected to detect the concentration of ALT and TSB (liver functions). Urea and creatinine (a kidney function) concentration was measured. Testosterone, LH, and FSH (male reproductive function) concentration were evaluated. Our results revealed a significant reduction in ALT concentration in the grape seed extraction group compared with the control group. Total serum bilirubin was non-detectable in both the grape seed extraction group as well as the control group. Urea and creatinine concentrations appeared to have no significant change between both grape seed extraction and the control group. Testosterone, LH, and FSH hormone levels were significantly raised in the grape seed extraction group compared with the control group. Prolactin hormone results revealed no change in both the grape seed extraction group and the control group. Our study showed up that grape seed extract can improve male reproductive hormones without any toxic effect on the liver or kidney.

A common characteristic of Mycoplasma diseases is their chronicity, Mycoplasma spp. infection have been frequently associated with upper respiratory infections, chronic lung disease , asthma, meningeal encephalitis, mastitis, arthritis, heart problems, sterility, bone problems , oviduct dysfunctions and death in human and different animal species. In former years, changeable expression of membrane antigens has been detected in a number of Mycoplasma spp., resulting in the assumption that immune prevarication may be an important part of the their infection and pathogenesis. It has been determined how the attachment organelle, which mediates the complicated interactions between various adhesins and auxiliary adhesion proteins to mediate the critical first stage of cytoadherence to respiratory tract epithelium. Additionally, it has been demonstrated that inflammatory cytokines cause tissue damage by intracellular localization, direct cytotoxicity, and activation of the inflammatory cascade via Toll-like receptors (TLRs), and inflammosome activation, which causes air passage inflammation. All of these play crucial roles in the infectious process. This paper seeks to provide a thorough assessment of recent developments in our understanding of Mycoplasma pathogenesis with the understanding of its virulence mechanisms.

Orf which is commonly referred to as contagious ecthyma is a viral infectious disease that infects small ruminants. Little is known about the disease status in our geographical region. This study aimed to determine the seroprevalence of Orf virus in sheep in Basrah province, southern Iraq. Serum samples were randomly collected from 380 sheep of different age and sex groups from 4 different regions in Basrah province, which were Zubair, Abulkhasib, Shatt Al-Arab, and Qurnah. The samples were tested by ELISA for the presence of IgG antibodies to the Orf virus. Out of 380 animals screened, 98 animals were found positive for ELISA, which reveals an overall prevalence of 25.7%. There was no significant difference in the seropositivity between male and female animals. On the other hand, the seropositivity was significantly higher in lambs of the age group 1-6 months in comparison with the other age groups (6-12 months and more than 12 months). This finding indicates that the virus is highly prevalent in Basrah province as confirmed by the ELISA test.
