Screening of 88 serum samples for the presence of MAP using ‘Indigenous ELISA’, 34 (38.6%) were positive for MAP infection.

Screening of 19 serum and 16 blood samples from 20 confirmed patients of ‘Type 1 diabetes’, 31.5 and 43.7% were positive by ‘Indigenous ELISA’ and IS<span class="CharOverride-8">900</span>&#160;PCR, respectively. Comparison of Indigenous ELISA and IS<span class="CharOverride-8">900</span>&#160;PCR revealed fair agreement between the two tests. Bio-typing of DNA of 8 positive blood samples by IS<span class="CharOverride-8">1311</span>&#160;PCR-RE revealed presence of ‘Indian Bison type’ biotype. Presence of MAP bacterimia in the patients suffering from Type 1 Diabetes added to the existing knowledge that MAP may provide foundation for establishing diabetes in human subjects. This is the first report of presence of MAP in human Type 1 Diabetes patients from India. ‘Indian Bison Type’ biotype in domestic livestock suggests a link and interspecies transmission through food chain.<span class="CharOverride-7"> </span></p>

MAP has also been associated with Inflammatory Bowel disease (Crohn’s disease) in human beings (Singh et al., 2008). Live cultivable MAP bacilli have been reported from milk based food items (ice creams, cheese, condensed milk, milk powder etc) world-wide (Grant et al., 2001; Ayele et al., 2005; Shankar<span class="CharOverride-7"> </span>et al., 2010). In India, raw milk serves as base of many Ayurvedic medicines. Recently role of MAP has been reported in different kinds of human diseases such as Type-1 Diabetes (Sechi et al., 2008), autoimmune thyroiditis (D’Amore et al., 2010), multiple sclerosis (Cossu et al., 2013), autism (Dow, 2011), sarcoidosis (EL-Zaatari et al., 1996) and autoimmune arthritis (Moudgil et al., 1997). Recent years witnessed a surge in cases of Type-1 Diabetes particularly the ‘Type 1 diabetes mellitus’, a chronic disease in which insulin producing beta cells of the pancreas are selectively destroyed by T lymphocyte infiltration, in human beings. Disease is the second most common chronic disease during childhood. Annual incidence of the Type 1 Diabetes (per 100,000) is consistently increasing and the highest being in European countries (32.5), followed by Non-Europeans (14.4), Maori (13.9), Pacific Islanders (15.4) and others (13.5) (Derraik et al., 2012). In Northern India, occurrence of Type 1 Diabetes was found to be 10.20 per 100,000 population with a higher prevalence in urban (26.6/100,000) as compared to rural areas (4.27/100,000)<span class="CharOverride-7">.</span> In the age group  of 5-16 years, prevalence is 22.22/100,000, while in 0-5 years age group prevalence is 3.82/100,000 (Kalra et al., 2010).</p>
			<p class="Body-Text ParaOverride-1">&nbsp;</p>
		  <p class="Body-Text ParaOverride-1">Susceptibility to Type 1 Diabetes is inherited, but mode of inheritance is not clearly understood. Several loci, primarily HLA and environmental factors might be responsible for manifestation of disease (Concannon et al., 2009; Van Belle et al., 2011). MAP has also been indicated as an environmental trigger that might contribute to Type-1 Diabetes pathogenesis (Sechi et al., 2008; Naser et al., 2013). Singh et al. (2014) reported high burden of MAP in different kinds of infectious and non-infectious disease conditions e.g., diabetes, liver disorders, anemia, thyroid disorder, tuberculosis, typhoid, abdominal disorders, inflammatory illness and ion imbalance in human population from North India<span class="CharOverride-7">. </span>The study aimed to screen human population for Type 1 Diabetes and <span class="CharOverride-8">Mycobacterium avium</span> subspecies <span class="CharOverride-8">paratuberculosis </span>in Chatarpur district of Madhya Pradesh state in India. </p>

A total of 111 human samples (88 serum and 71 blood) were collected from a ‘health camp’ organized by Gwalior Medical College at Chattarpur district of Madhya Pradesh to screen human population for diabetes and MAP infection.<span class="CharOverride-7"> </span>Of the 111 suspected human beings screened for diabetes, only 20 (18.0%) were positive using commercial kits (ACCU-CHEK blood glucose monitoring system, Roche).</p>

			<p class="Heading-2--History-in-MM-">Indigenous ELISA Kit</p>
			<p class="Body-Text ParaOverride-1">Human serum samples were screened by ‘Indigenous ELISA kit’ (Singh et al., 2007) for presence of MAP infection. Absorbance was read at 450 nm in iMark ELISA reader (BioRad). Defined positive and negative were simultaneously run. Optical density (OD) values were converted to sample to positive (S/P) ratios as per Collins (2002) to determine the status of MAP infection. Serum samples in positive and strong positive categories were considered positive for MAP infection. Ratio between mean OD of positive and negative control (≥ 4 times) was critical for calculating S/P ratio and categories were (0.00-0.09, negative; 0.10-0.24, suspected; 0.25-0.39, low positive; 0.40-0.99, positive; and 0.61-0.80, strong positive) as per Collins (2002).</p>

          <p class="Heading-1--Introduction----">&nbsp;</p>
            <p class="Body-Text">MAP is the etiological agent of <span class="CharOverride-8">paratuberculosis</span>, a chronic granulomatosis enteritis in domestic and wild ruminants including primates and human beings (Chiodini et al., 1984; Singh et al., 2010a, 2011, 2014). Recent Indian studies report sharp increase in bioload of MAP in domestic livestock species (Singh et al., 2013; Singh et al., 2014). A sub-clinically infected animal excrete huge quantities of bacilli in feces, milk, semen etc., and MAP is known to survive pasteurization temperature (Grant<span class="CharOverride-7"> </span>et al., 2001; Shankar et al., 2010). Therefore, high prevalence of MAP has been reported in raw milk, pasteurized milk and milk products (Ice cream, cheese, etc) in many countries including India and is a serious public health concern worldwide (Grant et al., 2001; Ikonomopoulos et al., 2005; Slana et al., 2008; Shankar et al., 2010). Singh et al. (2012) reported contamination of natural resources (soil and water) with MAP in North India. It is therefore important to restrict contamination of environment and natural resources by animal and human excreta laden with MAP in order to reduce transmission to animal and human population. To reduce contamination of human population with MAP, it is essential to reduce infection of MAP in animals, especially domestic livestock. Association between MAP and chronic inflammatory bowel disease (Crohn disease) has been reported and found to persist in cell wall-deficient form, escaping clearance by the host immune system (Sechi et al., 2008). Other reports suggested association of MAP with Type I diabetes (autoimmune disease) in patients from Sardinia (Italy), which is a MAP endemic and genetically isolated region (Rani et al., 2010; Cossu et al., 2011; Cossu et al., 2013, Bitti et al., 2012, Masala et al., 2014). Similarly country (India) possesses largest population of domestic livestock, which is endemic and has seen high surge in prevalence of MAP in animals and cases of Type 1 Diabetes in human beings. As per International Diabetes Federation about the number of diabetes patients may shoot up to 87 million in 2030 from current 50 million (Unwin et al., 2009). Rani et al. (2010) reported the role of gut microbiota, environmental micro-organisms and dietary factors as trigger the development of diabetes in genetically susceptible individuals. Present report tries to find a link between the two.</p>
          <p class="Body-Text">&nbsp;</p>
			<p class="Body-Text ParaOverride-1">Present study report 31.5% prevalence of MAP in 20 confirmed type 1 diabetes patients using ‘indigenous ELISA’. Singh et al. (2008) reported high sero-positivity in CD patients (100.0%), animal attendants (75.0%) and apparently normal human beings (38.0%) in North India. Other workers also reported presence of MAP in human population particularly in patients of CD and diabetes (Greenstein et al., 2003; Bitti et al., 2012). Singh et al. (2014), after screening of 23,196 sera samples, by indigenous ELISA kits, reported over all 34.0% sero-prevalence of MAP in human beings suspected for different kinds of ailments. However, after screening of 9816 patients suspected for diabetes, 28.3% were positive. Detection of MAP specific proteins (MAP3733c and MAP3738c) establishes association of MAP with Type 1 diabetes (Cossu et al., 2013). However, Rani et al. (2014) contrary to the above findings, reported no difference in serum immune-reactivity to MAP cell lysate or MAP3738c protein between diabetic cases and healthy control. A finding which is hard to prove in view of high population densities of animals and human beings in India and high to very high prevalence of MAP in native livestock population, otherwise call for sero-reactivity in apparently normal human beings. Since large number of reports in India exist, wherein MAP has been recovered from these apparently normal or healthy persons, therefore doubt, whether MAP can cause any real health problem in human beings leave alone IBD or CD. Contrarily Singh et al. (2014), after mass screening of human serum samples, exhibited sero-prevalence of MAP in number of suspected infectious and non-infectious conditions in human beings. </p>
		  <p class="Body-Text ParaOverride-1">&nbsp;</p>
			<p class="Body-Text ParaOverride-1">In the present study, 39.4% blood samples were positive for MAP bacterimia using IS<span class="CharOverride-8">900</span> blood PCR. Of the 16 blood samples collected from confirmed Type 1 Diabetes patients, 43.7% were positive by IS<span class="CharOverride-8">900</span> PCR. Our study correlates with the finding of some authors that have claimed the association of MAP infection with autoimmune disorder viz. Type 1 Diabetes and thyroid disorder etc. Recent advancements in MAP research indicated presence and role of MAP in patients with diseases such as Type-1 Diabetes (Sechi et al., 2008), autoimmune thyroiditis (D’Amore et al., 2010), multiple sclerosis (Cossu et al., 2013), autism (Dow, 2011), sarcoidosis (EL-Zaatari et al., 1996) and autoimmune arthritis (Moudgil et al., 1997). Singh et al. (2014) screened 3093 blood samples of human beings suspected for different kinds of ailments for presence of MAP by IS<span class="CharOverride-8">900</span> PCR, 8.4% were positive for MAP infection. However, after screening of 451 blood samples of suspected diabetes patients, 4.8% were positive. Contrary to these findings Rani et al. (2014), though reported amplification of 16S rDNA in 66.0% healthy, 76.0% Type 1 Diabetes patients and 86.0% in type 2 diabetes patients, but none of these samples was positive in IS<span class="CharOverride-8">900 </span>PCR. Similarly, Sasikala et al., 2009, reported MAP specific sequences in the biopsies of Crohn’s disease patients from Hyderabad.</p>
		  <p class="Body-Text ParaOverride-1">&nbsp;</p>
			<p class="Body-Text ParaOverride-1">Of 28 IS<span class="CharOverride-8">900</span> PCR positive DNA samples, eight were subjected to IS<span class="CharOverride-8">1311</span> PCR_REA and all had ‘Indian Bison type’ restriction pattern, which was major biotype of MAP infecting domestic and wild ruminants and also human population in North India (Singh et al.<span class="CharOverride-8">, </span>2008; 2010a). Comparative evaluation of ‘Indigenous ELISA kit’ with IS<span class="CharOverride-8">900 </span>PCR showed that 14.7% human subjects were positive by ‘Indigenous ELISA’ as compared to 20.5% by IS<span class="CharOverride-8">900 </span>PCR. Cumulatively, 16 (23.5%) samples were positive by two tests indicating definite infection of the diabetes patients. Proportional agreement between ‘Indigenous ELISA kit’ and IS<span class="CharOverride-8">900 </span>PCR was substantial (64.7%) (Table 3 and 4). Moreover, presence of same genotype (Indian Bison Type), in domestic livestock, wild ruminants, other animals, primates, milk and milk products and environment samples proves sharing of genotype and interspecies transmission. Rani et al. (2014), justified non-reporting of MAP in limited human sera samples due to fact that association of mycobacterial trigger with diabetes could be a population specific phenomenon, highly dependent on genetic repertoire and the environment of susceptible population. Singh et al. (2014) also reported difference in sero-prevalence MAP in human population between two adjacent districts; Agra (14.2%) and Mathura (35.4%), which may be due to chance, since population in two regions is very similar except Agra is growing metropolitan city and Mathura is still rural type. Contention of Rani et al. (2014) that high genetic susceptibility with respect to presence of SLC11A1 gene in type 1 diabetes affected population of Sardinia (Pugazhendhi et al., 2008), which also has high rate of MAP infection in their livestock (Rani et al., 2010) may not be true in India since large variability exists both in Indian population with respect to animals (species and breeds) and human beings. </p>
		  <p class="Body-Text ParaOverride-1">&nbsp;</p>
			<p class="Body-Text ParaOverride-1">Economic significance of MAP in dairy enterprise in general and domestic livestock in particular, combined with contamination of milk and milk products (Public Health significance), risk of human infection and increasing role of&#160;MAP&#160;in the development of Crohn’s disease, type 1 diabetes and other incurable diseases in human beings highlight the need to minimize chances of entry of bug in to food chain. Present findings are first report from India supporting the hypothesis of probable association of MAP and type 1 diabetes suggesting that there is sufficient ground to warrant focus on MAP and its possible involvement in triggering Type 1 Diabetes.</p>
