[Study of primary resistance to antitubercular drugs in Galicia].
The primary resistance of 100 specimens of Mycobacterium tuberculosis isolated in patients with active tuberculosis confirmed bacteriologically was studied prospectively over a period of 15 months. Strains resistant to 1 or more drugs were found in 5 patients. Three patients presented resistance to 2 drugs (isoniazide and streptomycin in 2 and rifampicin and isoniazid, streptomycin and ethambutol); and the fifth was resistant only to pyrazinamide. Owing to the few instances of primary resistance found, it was impossible to establish whether any of the factors analyzed in each patient was related to a higher index of resistance, although 4 of the 5 resistant strains came from respiratory specimens. We conclude that the index of primary resistance in our area is low and this allows us to do without prescribing a fourth drug in the first two months of anti-tuberculosis therapy, and makes routine sensitivity tests unnecessary for patients with no history of prior treatment for tuberculosis.

RFLP analysis of mtDNA from six platyrrhine genera: phylogenetic inferences.
This study investigates the phylogenetic relationships of 10 species of platyrrhine primates using RFLP analysis of mtDNA. Three restriction enzymes were used to determine the restriction site haplotypes for a total of 276 individuals. Phylogenetic analysis using maximum parsimony was employed to construct phylogenetic trees. We found close phylogenetic relationships between Alouatta, Lagothrix and Ateles. We also found a close relationship between Cebus and Aotus, with Saimiri clustering with the atelines. Haplotype diversity was found in four of the species studied, in Cebus albifrons, Saimiri sciureus, Lagothrix lagotricha and Ateles fusciceps. These data provide additional information concerning the phylogenetic relationships between these platyrrhine genera and species.
