1.4 Histopathology<br />

Although traditionally regarded as lymphatic <strong>filarial</strong> <strong>parasite</strong>s in <strong>the</strong>ir natural hosts,<br />

such as man, cats and monkeys, B, <strong>malayi</strong> and related species show a characteristic<br />

tendency to localize within <strong>the</strong> major organs like lungs, heart and testes <strong>of</strong> M. natalensis<br />

(section 4.1.2). in Meriones unguiculatuc (Ash, 1973b, Ash and Riley, 1974b; ElBihari<br />

and Ewert, 1971). Such development has been interpreted as an aborrant mode <strong>of</strong><br />

development (Ash, 1973a; Vincent et al.. 1976). Vincent el a/. (1976) studied <strong>the</strong><br />

chronological development <strong>of</strong> pulmonary pathology associated with B.<strong>malayi</strong>, B.pahangi<br />

and B. patei. Histological studies by Hawking et a1.(1950) had concluded that DEC in<br />

some way promotes phagocytosis <strong>of</strong> <strong>the</strong> mf. The enzyme studies in B.<strong>malayi</strong> infected<br />

animals in <strong>the</strong> present study has shown cellular injury and membrane damage, hence<br />

histopathological studies on various organs after <strong>infection</strong> and after DEC treatment was<br />

carried out
