Unlike the other methods, control of animal disease through genetic means would be cost effective and does not require continuous investment. This is due to the fact that once a desirable genetic resource is identified and/or achieved, it can be exploited for several generations without any additional input. In the present review, two general approaches or principles to be considered in the control of livestock disease through genetic means are reviewed. The first one is exploitation of the hosts genetic resource, which could be achieved through selection and propagation of those animals having no genetic defects and naturally resistant to a particular disease. Such animals can be prepared through use of transgenic animal technology in which genes for disease resistance have been incorporated. The second approach is genetic control of pathogens by employing several techniques. This includes control of vectors using conventional sterile insect release method, Y-autosome translocation or use of compound chromosomes, and identification and cloning of genes in pathogens responsible for the production of potent antigens which can be used in vaccine development via the application of recombinant DNA technology. Selecting cattle most resistant to the development of infectious diseases will decrease costs of production and should therefore be included in the overall breeding objective.","PeriodicalId":17430,"journal":{"name":"Journal of Veterinary Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76511567","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 disease is caused by pathogenic Leptospira species and considered to be an emerging or re-emerging disease in many countries of the world. Infection in domestic animals and wildlife can lead to economic loss and pose a potential spread to the communities. In the present study recombinant LigB protein is employed in latex agglutination test, which is a cross reacting lipoprotein able to detect acute infection caused by any pathogenic leptospiral serovars. It was employed for serodiagnosis of leptospirosis. The 46KDa 6X His tagged LigB protein, obtained by IPTG induction of recombinant E. coli M15 cells containing the N-terminal region of LigB gee in P QE30 expression vector, was purified by Ni-NTA affinity chromatography and adsorbed on latex bead surface for performing latex agglutination test against Leptospirosis suspected wildlife field sera. A total of 80 wildlife sera samples were collected, including 27 wild feline sera samples (18 tigers, 8 lions, and 1 jaguar) obtained from Chhatbir zoo, Chandigarh, 42 serasamples ( 8 tigers, 4 lions and 6 leopards, 2 cheethals, 1 black buck, 12 buffaloes and 9 zoo staff) sera and 3 live rodents ) were received from Jodhpur zoo Rajasthan, 8 sera samples (4 tigers, 3 leopards, 1 lion) sera from Van Vihar National park, Bohpal, Madhya Pradesh and 3 sera samples (2 lions,and 1 tiger) received from Biwani Mini zoo, Haryana, India. The result showed that sera were tested positive by rLigB based LAT, which were reconfirmed using microscopic agglutination test (MAT). The results from LAT were in concordance with MAT. In conclusion, rLigB based LAT is a rapid, pen site, reliable diagnostic tool of high sensitivity and specificity, under laboratory and field conditions, for the detection of Leptospirosis .","PeriodicalId":17430,"journal":{"name":"Journal of Veterinary Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89379112","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}

Hides and skins are the basic raw materials for the leather industry. The major sources for these raw materials are cattle, sheep and goats. The leather industry sub sector is still in its lower level of development. This sub sector is suffering from so many problems including diseases (like parasitic diseases such as mites basically demodex, psoroptes; bacterial diseases as dermatophillosis; fungal diseases like ringworms; and viral diseases like lumpy skin disease). The leather industry sub-sector also faces mechanical problems like flaying and branding, market availability and accessibility, transportation and the quality of raw materials supplied. Poor animal husbandry, bad practices in curing and collection, general handling and the potential of supply are the other factors that affect the leather sub sector. A lower attention is given to the Ethiopian livestock sector from which the raw materials come in relation to disease aspect, management of the mechanical problems, market conditions and others give a negative feedback to the leather industry sector. Due to these factors hindering the development of the leather sub-sector which are in need of greater care and management, the contribution of the sector to the national income is disproportionately small. Higher level of attention is needed to be given from government; stakeholders and professional sectors to improve the current status of skin and hides to that serve as the input for the leather industry that enables us to have a good quality output for foreign currency.","PeriodicalId":17430,"journal":{"name":"Journal of Veterinary Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87634996","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 prevalence of hydatidosis in this study was significantly higher (P<0.05) in cattle with age group of more than 10 years (56.8%) and in animals having poor body condition (62.02%). Of the total 199 infected cattle, 109(54.77%) of them had hydatid cysts only in their lung, 42(21.1%) in liver, 5(2.51%) in spleen, 3(1.5%) in heart and 2(1%) in their kidney while the rest 28(18.08%) had multiple organs infection.

Of the 415 livers and fecal sample examined, 127 (30.6%) and 103 (24.8%) were positive, respectively. Both Fasciola hepatica and F. gigantica were identified during the study. However F. gigantica was more prevalent (27.0%) than F. hepatica (3.6%) (P<0.05). There was strong association (P<0.001) between animal origin and Fasciola prevalence. Fasciola prevalence was higher in cattle from low-land (46.0%) areas compared to cattle from mid altitude areas (18.0%). Comparison of coprological examination with postmortem examination by taking the latter as gold standard, demonstrated almost perfect agreement between the two ( Kappa statistics= 0.86).
