It is a bacterial infection of the eye that causes inflammation and in severe cases temporary or permanent blindness. In cattle, the gram-negative bacterium Moraxella bovis is regarded as the main cause of the disease that affects cattle of all ages and occurs worldwide. Also, Moraxella bovoculi and a range of other bacteria, viruses, and environmental conditions seem to be involved. Moraxella bovis has several pathogenic mechanisms; however, only two, pili and the secretion of a β-hemolytic cytotoxin, have been determined to cause clinical disease. The pili allow the bacteria to attach to the dark cells of the corneal epithelium. The hemolysin is a pore-forming toxin that lyses corneal epithelial cells leading to ulceration and causes lysis of bovine leukocytes. The virulence of Moraxella bovis is influenced by both host and environmental factors. It is one of the examples of the diseases that may cause production losses in both dairy and beef farms in many countries. The economic impact of the disease is significant due to its high contagious nature. Most cattle producers are familiar with this disease but may not know how to best treat it and minimize its spread within the herd. The cost and time used in treating infected cattle adds to the economic losses. The best strategies to prevention and control of an outbreak are maximizing the herd’s immune status, minimizing the concentration of the Moraxella bacteria, and maintaining as irritant-free environment as possible. Treatment decisions are influenced by numerous factors such as effectiveness of the drug selected, cost, labor availability, withholding times, facilities, and availability of veterinary support. Vaccines are partially protective and cannot be completely relied upon to prevent the disease. Coming up with one solution is difficult because of all the contribution factors. Therefore, isolation and a swift reaction are keys in reducing the spread of the disease.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131438779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Face-to-face interviewing of the cow owners using a semi-structured questionnaire on the randomly selected dairy cows was employed to get the necessary information. A total of 310 dairy cows were studied, employing a questionnaire survey, out of which, 30.3% (n = 94) were affected by at least one or more clinical reproductive health problem. Dystocia, repeat breeder, retained fetal membrane, abortion; metritis, anestrous and uterine and vaginal prolapse were recorded with prevalence of 15.5%, 8.1%, 5.3%, 4.5%, 2.6%, 2.3% and 1.0%, respectively. The prevalence of clinical reproductive problems showed significant differences (P<0.05) with respect to parity, hygienic condition and age of an animal. The problems were more commonly reported in poor hygienic conditions, higher age groups and greater number of parities. This study indicated clinical reproductive problems, which included dystocia, repeat breeder, retained fetal membrane and abortion as the major factors responsible for the low reproductive performance of dairy cows in Asella town. Improvements in management systems, proper heat detection and proper selection of bulls for breeding could help in minimizing reproductive health problems and hence, improve the reproductive efficiency of dairy cows.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134424048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, viruses from free-living replicating elements evolved into parasites that embed their genetic material into the nucleotide sequence of the carrier. Naturally, any alien genetic material is perceived by the body of an infected creature as a threat, prompting, in turn, the response of the immune system [4]. The consequences of this response, such as fever, tumor and cell apoptosis, are quite painful processes that sometimes lead to the death of the host organism [5]. Since many viruses are characterized by a mode of transmission between individuals of the host species, or even interspecific transmission, viral diseases often become epidemics. Since the external symptoms of various viral diseases are quite like each other, animal husbandry in general and poultry farming constantly need to improve old ones and develop new methods for diagnosing viral diseases [6,7]. The purpose of this review is to briefly describe the current methods for diagnosing avian influenza virus and Newcastle disease, some of the most dangerous and common infections of birds [8,9].","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127180144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the work is to determine the phytochemical contents, diameter of inhibition and minimum inhibition concentration of the grasses studied. The four-plant species were found to contain alkaloid, saponin, tannins, flavonoid and phenols in varying proportions. The phytochemical contents of C. papaya (Pawpaw) were as follows: alkaloid (1.11 ± 0.02%), saponins (0.53 ± 0.04%), tannin (0.43 ± 0.4%), flavonoid (0.67 ± 0.01%) and phenols (0.91 ± 0.03%). For Citrus Paradisi (Grape) alkaloid content was (0.31 ± 0.05), saponins (0.19 ± 0.01), tannins (0.25 ± 0.01), flavonoid (0.36 ± 0.02), phenol (0.52 ± 0.04). In Citrus sinensis (Orange), alkaloid was (0.23 ± 0.01), saponin (0.23 ± 0.01), tannin (0.15 ± 0.01), flavonoid (0.33 ± 0.01) and phenol (0.59 ± 0.07). For Vernonia amygdalina Del. Cent (Bitter leaf), alkaloid (1.31 ± 0.03), saponin (1.15 ± 0.01), flavonoid (0.71 ± 0.02), tannin (0.43 ± 0.01), phenol (1.15 ± 0.01). The anti-microbial activity of the ethanolic and aqueous extracts of leaves of the plants were tested against four microorganisms; Salmonella pullorum, Klebsiella pneumonia, Enterobacter aerogenes and Proteus vulgaris. The susceptibility of the microorganisms was determined using the disk diffusion method. The leaf extract of these plants inhibited the growth of these pathogens. All the ethanolic leaf extracts of the plants inhibited the clinical isolates. The minimum inhibitory concentration was analyzed using agar well diffusion method with values ranging between 50 mg/ml and 200 mg/ml against all the clinical isolates. There were variations in the lowest concentrations of the different plant extracts that caused inhibitions against the various microorganisms.","PeriodicalId":403730,"journal":{"name":"Journal of Dairy & Veterinary Sciences","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125970043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
