Therapeutic trial of doxycyclin plus ivermectin for the treatment of Brugia malayi naturally infected cats.

Lymphatic filariasis (LF) is one of the neglected tropical diseases which causes permanent and long term disability worldwide. LF is caused by filarial nematode parasites, i.e.

MIDGUT ULTRASTRUCTURE OF FOURTH INSTAR OCHLEROTATUS TOGOI (DIPTERA: CULICIDAE).

The ultrastructure of the midgut of fourth instar Ochlerotatus togoi was investigated by light, scanning and transmission electron microscopy. This study was performed to provide information to help devise future control efforts aimed at the larval stages of this vector of filariasis. The fourth instar midgut was approximately 2 mm in length and consisted of three morphologically distinct cell types: epithelial, regenerative, and endocrine cells.

Morphological and protein analyses of adult female salivary glands of Anopheles barbirostris species A1 (Diptera: Culicidae).

Morphology and protein profiles of female salivary glands of Anopheles barbirostris species A1 were analyzed. Female glands consisted of a distinctive tri-lobed structure connected to a main salivary canal, a single medial and two lateral lobes with proximal and distal portions. Cellular architecture was similar among the lobes, with secretory material appearing as large masses.

Cytogenetic, crossing and molecular evidence of two cytological forms of Anopheles argyropus and three cytological forms of Anopheles pursati (Diptera: Culicidae) in Thailand.

Nine and 11 isolines of Anopheles argyropus and Anopheles pursati, respectively, were established from individual females collected from cow-baited traps, and the characteristics of metaphase chromosomes were investigated in their F1-progenies. As determined by the different amounts of extra heterochromatin on sex chromosomes, 2 types of X (X1, X2) and Y (Y1,Y2), and 2 types of X (X1, X2) and 3 types of Y (Y1, Y2, Y3) chromosomes were obtained from An. argyropus and An.
