Rapid detection of Mycobacterium tuberculosis in sputum by Patho-TB kit in comparison with direct microscopy and culture.

The usefulness of a new rapid diagnostic test (Patho-TB) using antibodies specific to mycobacterial antigens was evaluated for the rapid discrimination between pulmonary tuberculosis (TB) and non-TB pulmonary diseases on sputa. One hundred sputa collected from 79 active TB patients and from 21 patients with non-TB pulmonary diseases (asthma and chronic obstructive pulmonary disease) were enrolled into the study and tested for the presence of Mycobacterium tuberculosis by Ziehl-Neelsen smear, Patho-TB kit, and Löwenstein-Jensen culture. The sensitivity, specificity, positive predictive value, and negative predictive value of the Patho-TB test were 95%, 100%, 100%, and 84%, respectively.

Occurrence of Leishmania infantum cutaneous leishmaniasis in central Tunisia.

Cutaneous leishmaniasis (CL) due to Leishmania infantum occurs sporadically in Tunisia where its distribution is confined to the northern parts of the country. However, during the past decade there have been occasional repeated reports of cases from areas in central Tunisia, known to be free of CL. Epidemiological, clinical and parasitological data regarding these patients were collected and analysed.
