243. PCR amplification and high resolution melt curve analysis as a rapid diagnostic method to genotype members of the Mycobacterium avium-intracellulare complex. Full Text available with Trip Pro

PCR amplification and high resolution melt curve analysis as a rapid diagnostic method to genotype members of the Mycobacterium avium-intracellulare complex. Some of the members of the Mycobacterium avium–intracellulare (MAI) complex are recognized as human pathogens in both immunocompromised and immunocompetent patients. The current molecular methods that are available for genotyping the MAI complex members can be both expensive and technically demanding. In this report, we describe (...) for the first time the application of a real-time PCR and high-resolution melt approach to differentiate between the complex members by targeting a member of the Pro- Pro-Glu gene family, MACPPE24. To this end, reference strains of the M. avium subspecies and Mycobacterium intracellulare were used to optimize the technique. Then, this real-time PCR–high-resolution melt approach was used to distinguish ten M. avium ssp. hominissuis field isolates from the M. intracellulare reference strain.

244. Multiplex PCR for detection of clarithromycin resistance and simultaneous species identification of Mycobacterium avium complex. (Abstract)

Multiplex PCR for detection of clarithromycin resistance and simultaneous species identification of Mycobacterium avium complex. Multiplex PCR (mPCR) was established for the simultaneous detection of clarithromycin (CLR) resistance and species identification of Mycobacterium avium complex (MAC). mPCR was tested on 218 MAC clinical isolates. CLR-resistance was detected by mPCR in 31 of 35 isolates identified by a microdilution method. Of the remaining 187 susceptible isolates identified by mPCR (...) , 183 isolates had MIC < or = 8 microg/ml (susceptible), 3 with MIC of 16 (intermediate resistant) and 1 with MIC of > or = 32 microg/ml (resistant). Comparing with the PCR-restriction enzyme analysis, mPCR concordantly identified 185 isolates either as being M. avium or M. intracellulare, whereas one isolate was misidentified and 32 isolates could not be identified. Comparing with reference methods, the mPCR showed the sensitivity, specificity, positive predictive and negative predictive value

245. Hospital Water Filters as a Source of Mycobacterium avium Complex. Full Text available with Trip Pro

Hospital Water Filters as a Source of Mycobacterium avium Complex. Bronchoscopes and the filters used for washing them were found to yield high numbers of Mycobacterium avium isolates sharing the same repetitive sequence-based PCR (rep-PCR) fingerprint pattern as M. avium isolates recovered from patient samples collected by bronchoscopy. Water and biofilm samples collected from the bronchoscopy preparation laboratory yielded M. avium, Mycobacterium intracellulare, Mycobacterium malmoense (...) and Mycobacterium gordonae. Several M. avium and M. intracellulare isolates from water samples in the bronchoscopy laboratory had rep-PCR patterns matching those of patient bronchoscopy isolates. Five of the 22 (23 %) M. avium patient bronchoscopy isolates and 42 of the 56 (75 %) M. intracellulare patient bronchoscopy isolates could have been due to contamination from the water supply.

Mimicry of the Pathogenic Mycobacterium Vacuole In Vitro Elicits the Bacterial Intracellular Phenotype, Including Early-Onset Macrophage Death Mycobacterium avium complex (MAC) within macrophages undergoes a phenotype change that allows for more efficient entry into surrounding host cells. We hypothesized that, by developing an in vitro system resembling the intravacuolar environment, one could generate insights into the mycobacterial intracellular phenotype. MAC was incubated in "elemental (...) of the intracellular phenotype. It was demonstrated that bacteria harboring the intracellular phenotype induced early-onset macrophage death more efficiently than bacteria grown in broth. This new trace elemental mixture mimicking the condition of the vacuole at different time points has the potential to become an effective laboratory tool for the study of the MAC and Mycobacterium tuberculosis disease process, increasing the understanding of the interaction with macrophages.

ascites were identified and compared according to causative pathogens (Mycobacterium tuberculosis or NTM). Those with NTM peritonitis were further classified into the 'probable' and 'possible' groups based on diagnostic evidence. Twenty-five patients with NTM peritonitis and 65 with tuberculous peritonitis were reviewed. Mycobacterium avium complex was the most common NTM pathogen (52%). There was no obvious difference between the 'probable' and 'possible' NTM peritonitis groups regarding age (...) Mycobacterial peritonitis: difference between non-tuberculous mycobacteria and Mycobacterium tuberculosis.

250. Mycobacterium avium subsp. paratuberculosis as a trigger of type-1 diabetes: destination Sardinia, or beyond? Full Text available with Trip Pro

Mycobacterium avium subsp. paratuberculosis as a trigger of type-1 diabetes: destination Sardinia, or beyond? Type 1 diabetes mellitus (T1DM) is a multifactorial autoimmune disease in which the insulin producing beta cell population is destroyed by the infiltrated T lymphocytes. Even though the exact cause of T1DM is yet to be ascertained, varying degree of genetic susceptibility and environmental factors have been linked to the disease progress and outcome. Mycobacterium avium subsp (...) mycobacterial proteins (Hsp 65) and pancreatic glutamic acid decarboxylase (GAD 65) and infant nutrition studies implicate MAP as one of the triggers for T1DM. PCR and ELISA analyses in diabetic patients from Sardinia suggest that MAP acts as a possible trigger for T1DM. Systematic mechanistic insights are needed to prove this link. Unfortunately, no easy animal model(s) or in-vitro systems are available to decipher the complex immunological network that is triggered in MAP infection leading to T1DM.
