    A new focus of cutaneous leishmaniasis due to Leishmania amazonensis in a Sub Andean region of Bolivia
    (Facultad de Medicina, Enfermería, Nutrición y Tecnología Médica, 1988) Martínez, E
    Abstract We detected a new outbreak focus with high incidence of cutaneous leishmaniasis in the Sub Andean region of La Paz. This area was never considered previously as an endemic zone of leishmaniasis. Leishmania stocks from human lesions were isolated: three stocks were explored by pulse field gradient electrophoresis, showing evidence for their affiliation to the L. mexicana complex. Eight stocks were submitted to isoenzyme electrophoresis and compared with five reference strains: L. amazonensis, L. braziliensis, L. chagasi, L. mexicana and L. pifanoi. Close genetic proximity was evidenced between newly isolated parasites and the reference stock of L. amazonensis, whereas high divergence was observed between them and either the L. pifanoi, L. mexicana, L. braziliensis and L. chagasi reference strains.

    Adult and nymphs of Microtriatoma trinidadensis (Lent, 1951) (Hemiptera: Reduviidae) caught from peridomestic environment in Bolivia.
    (2001) De la Riva, J; Matias, A; Torrez, M; Martínez, E; Dujardin, J P
    This is the first report of adult and nymphs (20 nymphs of all stages and 4 adults) of Microtriatoma trinidadensis (Lent 1951) (Hemiptera: Reduviidae: Triatominae) collected in peridomestic environment, in the department of La Paz, Bolivia. These specimens were associated to Rhodnius stali Lent, Jurberg & Galvão 1993. The exceptional finding of M. trinidadensis in peridomestic environment, illustrates the general tendency of triatominae to adapt to human dwellings and dependences.
