Such antibodies with single isotype have higher specificity, and the serological tests employed in show higher reproducibility compared to those with use of polyclonal antisera. There are several procedures of mAb production which vary considerably but the principle remains the same which states that antigens introduced into animals generally result in the stimulation of lymphocytes, some of which produce antibody of only one type, although the isotype may change. The developments in the field of cell culture and transfection technology have lead to the production of improved qualities of mAbs. In general, monoclonal antibodies are important reagents used in biomedical research, such as, in the field of diagnostics and therapeutics as well as targeted drug delivery systems. They have got importance not only for infectious diseases caused by microbes and parasites, but also for cancer, metabolic and hormonal disorders, in the diagnosis of lymphoid and myeloid malignancies and tissue typing, enzyme linked immunosorbent assay (ELISA) (especially blocking ELISA), radio immunoassay (RIA), serotyping of pathogens and their immunological intervention with passive antibody, anti-idiotype inhibition or magic bullet therapy with cytotoxic agents coupled with antimouse specific antibody. The application of mAbs in diagnosis of various livestock diseases is an important area of concern as these diseases are a major and increasingly important factor reducing livestock productivity in various parts of the world. In this context, the application of mAbs for diagnosis of important bacterial diseases viz., Anthrax, Brucellosis, Paratuberculosis, Leptospirosis, Listeriosis, Clostridial infections and Mycoplasmosis (CBPP), fungal diseases viz., Zygomycosis, Cryptococcosis, Histoplasmosis and Paracoccidiodomycosis, viral diseases viz., Foot-and-mouth disease (FMD), Infectious bovine rhinotracheitis/Infectious pustular vulvovaginitis (IBR/IPV), Rota viral diarrhoea, Blue tongue, Rabies, Classical swine fever and re-emerging viral diseases like Hendra and Nipah viral infections and parasitic diseases viz., dirofilariosis, and Trichinellosis and haemportozoan diseases (including Trypanosomiasis, Leishmaniasis, Anaplasmosis, infections caused by Plasmodium spp. as well as tick borne diseases) have been discussed thoroughly along with the specifications of the diagnostic assays for each disease for the convenience of the diagnosticians, researchers, scientists and students to employ such assays, both in field and laboratories to strengthen the disease control programme.展开更多

MAP has also been associated with inflammatory bowel disease (IBD) so called Crohn’s disease (CD) of human beings, which is incurable even after surgery. By virtue of the pasteurization resistant power, high endemicity of the infection in animals continues to be the permanent source of infection to human population. High bio-burden of MAP in wide range of biotic (animal hosts including human beings) and abiotic environment in each and every country where it has been investigated, serves a reminder about the survival abilities of the MAP in diverse range of environmental conditions. Ability of the MAP to evade immune system of the host and the temporal events during infection of the macro-phages, is an area of major concern and research activities as the pattern of distribution are quiet different from those of other pathogenic intracellular organisms. Moreover, the organism can survive over a wide range of environmental conditions such as high and low environmental temperatures, pasteurization, low pH, and high salt concentration etc. This superior survival efficiency from environmental degradation and dormancy within host allows the pathogen to be available for causing disease and pathogenicity in animals and human beings, when conditions are favorable. Perusal of literature reveal that, despite the availability of whole genome sequence of MAP, a very little is known about the replication, persistence and survival mechanisms of this pathogen. Therefore, this review tries to address the survival mechanisms of Mycobacterium avium subspecies paratuberculosis in the different host species and adverse environmental conditions in order to allow designing of more rational diagnostic and control procedures.展开更多
