Abstract

MEDEIROS, Jansen Fernandes; PY-DANIEL, Victor; BARBOSA, Ulysses Carvalho  and  OGAWA, Guilherme Maerschner. Current profile of Mansonella ozzardi (Nematoda: Onchocercidae) in communities along the Ituxi river, Lábrea municipality, Amazonas, Brazil. Mem. Inst. Oswaldo Cruz [online]. 2008, vol.103, n.4, pp. 409-411. ISSN 0074-0276.  http://dx.doi.org/10.1590/S0074-02762008000400017.

The objective of this paper was to describe the current status of Mansonella ozzardi prevalence among the inhabitants of 12 communities along the Ituxi river, in Lábrea municipality, state of Amazonas. The prevalence of M. ozzardi was determined using thick blood smears obtained by digital punctures. M. ozzardi was found in 30.23% of the samples collected (39/129), with similar prevalence between genders (males: 30.30%; females: 30.16%); the highest prevalence was found in homemakers (45.45%) followed by farmers (38.77%). Among age groups, males and females older than 48 exhibited the highest rates. These results show a significative increase in the prevalence when compared to a epidemiological study made 26 years ago in the same area as well as a different epidemiological profile (gender and occupation) in relation to other areas in Amazonas.
