Fifty five milk samples were collected from dairy Friesian cows suffering from clinical mastitis in a farm at Quena Governorate. The samples were subjected to microbiological examination .The main isolated pathogenic bacteria were identified biochemically as Escherichia coli (36.3%), Staphylococcus aureus (23.6%) Streptococcus agalactiae (18.2%), Klebsiella pneumoniae (12.7%) and bacterial free samples (9.1%) . Sensitivity tests for the bacterial isolates revealed that the tested strains were sensitive to ciprofloxacin, nortril, gentamicin and lincospectin

lumpy skin disease virus (LSDV) was isolated, from naturally infected cattle that have a history of previous vaccination with live attenuated sheep pox virus (SPV) vaccine. The virus was isolated on chorio-allantoic membranes (CAM) of embryonated chicken eggs (ECE) and Madin Darby Bovine Kidney Cells (MDBK) and identified by agar gel precipitation test (AGPT) and immunofluorescent antibody technique (IFA). Characteristic pock lesions and intracyptoplasmic flourescene granules are identified respectively. Molecular characterization using polymerase chain reaction (PCR) using specific primer for G-Protein Coupled Chemokine Receptor Gene of LSDV isolates specific amplified product 554 bp. Sequence analysis revealed tow new isolates of LSDV.

The bronchopneumonia of calves represents a risk to national supply chain because it is an ecopathy and weakens the more intensive production systems. It is characterized by inflammatory changes in the bronchi, bronchioles, lung parenchyma, and pleura. It is a disease of multifactorial traits called Bovine Respiratory Disease (BRD). The association of infectious agents with host defense and management to which the animal is subjected leads to the emergence of major clinical manifestations of the disease. The clinical evolution of BRD can also have serious secondary changes such as pulmonary edema, sepsis, and pulmonary hypertension, or even be consequent to the involvement of other structures, such as in cases of myocarditis leading to congestive heart failure. Although this report refers to a non-experimental framework, the circumstances that caused the calf to be subjected to a protocol-specific respiratory assessment involving non-routine reviews has made it possible to associate circulatory and respiratory conditions, rarely considered in ruminant clinic. The focus of this report was pulmonary edema. Modern clinical vision requires of the veterinarian work with cost-benefit relation, so that the more accurate and the earlier the clinical diagnosis the less expensive the treatment.

Several factors can affect bovine mammary gland health and although bacterial mastitis is the most studied and reported cause, viral infections may also have negative effects on bovine udder health. Viral infections can indirectly damage the papillary duct of the teat, and induce or exacerbate signs of bovine mastitis due to viral-induced immunosuppressive effects that may lead to a greater susceptibility to bacterial mastitis and even intensify the severity of established bacterial infections. Some viruses (Bovine alphaherpesvirus 2, cowpox, pseudocowpox, foot-and-mouth disease, vesicular stomatitis and papillomavirus) affect the integrity of the udder skin, leading to teat lesions, favoring the entry of mastitis-causing pathogens. It is therefore possible that the association between mastitis and viruses is underestimated and may, for example, be associated with negative bacterial culture results. Few milk samples are tested for the presence of viruses, mainly because of the more laborious and expensive procedures required. Furthermore, samples for virus testing would require specific procedures in terms of collection, handling and storage. Thus, there is a knowledge gap in regard to the actual impact of viruses on bovine udder health. Despite the fact that serum anti-virus antibodies can be detected, there is not enough evidence to confirm or exclude the effect of viruses on udder health. However, any expectation of milk production from healthy animals should consider the possible impact of viral infections in mastitis development and not underestimate the importance of actions to diagnose and control the disease. Therefore, the purpose of this review is to describe the association of diagnosis and control of viral diseases and their effect on bovine udder health.

Prostaglandin F2α (PGF2α) determines luteolysis in cattle, and the ability to manipulate its endogenous synthesis is indispensible for large-scale animal breeding. Estradiol (E2) and progesterone (P4) modulate several molecular pathways in endometrial cells, including the synthesis of PGF2α; however, its specific mechanisms are still not totally known. This study investigated the production in vitro and possible modulation of endometrial PGF2α due to a local effect of endogenous E2 in the ipsilateral uterine horn (UH) containing the dominant follicle (DF) or from P4 in ipsilateral horn containing the corpus luteum (CL). The PGF2α stimulators oxytocin (OT) and phorbol 12,13-dibutyrate (PDBu) were incubated with endometrial explants, and PGF2α content was measured. For that, cycling cows were synchronized, the development of DF and CL was examined by ultrasonography and on the seventh day of the estrous cycle, endometrial explants were collected and cultured in medium supplemented with 10-6 M PDBu or 10-6 M OT or non-supplemented. Media samples were collected immediately after treatment and 60 min later. Radioimmunoassay showed that the PGF2α content of the UH ipsilateral to the DF was 49% less than that of the contralateral UH (8.22 ± 0.95 vs. 12.24 ± 0.95 pg/mL/mg tissue, respectively; P < 0.01). However, the PGF2α levels did not differ between the UHs as a function of the CL position (9.46 ± 0.95 vs. 11 ± 0.95 pg/mL/mg; P > 0.05). The cellular stimulators promoted an increase in PGF2α synthesis (P < 0.02), and the effects differed among the animals (P < 0.04). The PGF2a production was higher in the explants treated with PDBu rather than OT (13.68 ± 1.16 vs. 10.01 ± 1.16 pg/mL/mg tissue, respectively; P < 0.05). In conclusion, PGF2α synthesis is modulated by the presence of the DF (local E2) but not the CL (local P4), and both PDBu and OT stimulated PGF2a synthesis.

Objective: A significant number of animals enrolled at UVH regularly from surrounding villages for treating their sick animals, de-worming, vaccination purposes. Therefore, a study was done to define the occurrence of common diseases and disease conditions in cattle and goats at the Upazilla Veterinary Hospital, Debidwar under Comilla district. Materials and methods: Data on various diseases were collected from the record book of hospital during April 2016 to March 2017. The total number of animals were 889, among which cattle were 637 (71.65%) and goats were 252 (28.35%). The presumptive diagnosis was performed based on general examination, physical examination, and clinical examination of animals, and microscopic examination based on common laboratory techniques. Results: Based on clinical examinations, 14 different types of diseases and disease conditions were detected. In cattle (N=637; 71.65%), where FMD (14.44%, n=92), mastitis (6.59%, n=42), digestive disorders (19%, n=121), respiratory disorders (6.12%, n=39), parasitic infestations such as mixed infestation of both ecto- and endo-parasites (34.22%, n=218), acidosis (1.88%, n=12), myiasis (6.12%, n=39), corneal opacity (1.57%, n=10), protozoal diseases (1.26%, n=8), BQ (2.20%, n=14), milk fever (0.94%, n=6), reproductive disorders (4.87%, n=31) and others (0.75%, n=5) were detected. Age wise prevalence in young and adult were (38.62%, n=246) and (61.38%, n=391), respectively. Moreover, sex wise prevalence in male and female were (34.85%, n=222) and (65.15%, n=415) respectively. In goat, (N= 252; 28.35%) 11 different types of diseases and disease conditions such as PPR (12.30%, n=31), mastitis (2.38%, n=6), digestive disorders (19.84%, n=50), parasitic infestation (29.76%, n=75), respiratory disorders (15.08, n=38), myiasis (11.11%, n=28), corneal opacity (4.76%, n=12), acidosis (1.98%, n=5) protozoal diseases such as babesiosis, anaplasmosis (0.79%, n=2) and reproductive disorders (1.59%, n=4), correspondingly. Sex wise prevalence in male and female goat were (44.05%, n=111) and (55.95%, n=141), respectively. Conclusion: All the diseases and disease conditionswere recorded more or less frequently among all age group of cattle and goats though some of the specific diseases and disease conditionshad specific age and species susceptibility such as black quarter in young cattle and PPR in young goats, respectively. A comprehensive updated data with the total population record of that area and proper analysis is needed to identify the actual level of disease and disease conditions in UVH.

Objective: This study assessed personality traits in five cattle breeds (Bos taurus), two cosmopolitan (Holstein Friesian and Brown Swiss) and three endangered Italian autochthonous (Varzese, Rendena, and Modenese). Our aim was to provide an evaluation of the personality dimensions obtained by our questionnaire in order to compare some Italian autochthonous breeds with the cosmopolitan one. Our choice fell upon the comparison of the Varzese, the Modenese, the Rendena, the Brown Swiss, and the Holstein Friesian because the genetic selection at the base of the typical attitudes has induced different characteristics, and as a consequence, detectable differences in personality can be expected between the populations.Materials and methods: A personality questionnaire was completed by milkers/owners for each subject involved in this study. The milking staff involved in the study have been working with cows for over 20 years; they have experience with numerous breeds, and therefore, can be considered expert evaluators since they certainly have an appreciation of the full range of cow behavior. Results: The milkers assessments analysis found breed differences in dairy cattle, showing that certain personality traits are more marked in certain breeds in terms of curiosity, friendliness to milkers, and responses to unknown people.Conclusion: This pilot survey shows the usefulness of questionnaires in cattle personality studies, highlighting some peculiarity of the endangered breeds.

Objective: Sarcocystis spp. are common parasites and in terms of economics and pathogenicity in domestic animals is important. The purpose of this work was to define the rate of contamination of slaughtered carcasses of cattle to Sarcocystis using digestive and histopathological methods in southeast Iran.Material and Methods: In this descriptive laboratory study for 1 year, 500 carcasses were examined and isolated bradyzoites of Sarcocystis with the digest method. Also, tissue samples from the esophagus and diaphragm were considered for pathologic studies and stained with hematoxylin and eosin of sections of histopathological.Results: The results showed that the highest contaminations were in imported male animals aged 23 years old in the spring. There was a significant difference (p < 0.05) in the prevalence rate with the sex and race of cattle but no significant difference (p > 0.05) in the prevalence rate with age and season.Conclusion: Infection with Sarcocystis is common in oxen in this region. The imported cattle are more infected. It seems that racing and the environmental condition affect the prevalence of Sarcocystosis. [J Adv Vet Anim Res 2018; 5(4.000): 381-387]
