in this work, we reported the synthesis and evaluation of antimycobacterial and antifungalactivity of a series of thiocarbohydrazone derivatives which are thiacetazone congeners. thetarget compounds were synthesized in superior yields by reacting thiocarbohydrazide withdifferent aromatic aldehydes and methyl ketones. compounds 8, 19 and 25 were found to bethe most potent derivatives, exhibiting...

conclusion the high discriminative power of hsp65 pattern particularly hpaii digestion, provide an exact and costeffective method for rapid identification of m. simiae strains among registered pulmonary cases. results of 962 culture positive specimens, 17(1.7%) were identified as m. simiae species; majority of them were multidrug-resistance (12; 70.5%). the overall detection rate by tb11, tb12 ...

introduction: fish mycobacteriosis is caused by the non-tuberculous mycobacteria. infected fish are normally the primary source of infection, although non-tuberculous mycobacteria can be found in the environment. the present study was designed to  investigate the few recently found suspected cases of mycobacteriosis in iranian ornamental fish tanks.   materials and methods: pathological specime...

anti-adhesion therapy represents a potentially promising avenue for the treatment and prevention of tuberculosis in a post-antibiotic era. adhesins are surface-exposed microbial structures or molecules that enable pathogenic organisms to adhere to host surfaces, a fundamental step towards host infection. although several mycobacterium tuberculosis adhesins have been identified, it is predicted ...

background and objectives: pigeons are extensively kept for homing and racing purposes in iran. the main objective of this study was to investigate dissemination of m. avium subsp. avium (maa) in pigeon aviaries in tabriz, north-western iran. materials and methods: postmortem pathologic specimens from thirty-nine out of 140 birds collected from private flocks (n = 3), were subjected to bacteria...

background: tuberculosis continues to be a serious public health problem causing nearly three million deaths per year all over the world. despite major improvement in diagnosis, it is not possible to control the disease in the absence of surveillance treatment, and follow-up programs. objectives: this research was designed to study the frequency of mycobacterium tuberculosis among specimens ref...

conclusions concurrent pulmonary nocardiosis and tuberculosis is frequent in hiv-infected patients. rapid and sensitive methods such as pcr are recommended for detection of such co-infections. results from 157 sputum specimens, positive samples by acid fast staining, culture and pcr for m. tuberculosis were reported for 7.6% (12/157), 10.1% (16/157) and 7% (11/157) of samples, respectively. no ...
