CURRENT IDEAS ON OBLIGATE AND FACULTATIVE RELATIONSHIPS BETWEEN MAN AND THE DIROFILARIASIS PATHOGEN DIROFILARIA (N.) REPENS

The ability of D. repens to complete its ontogenesis in man points to their obligate, rather than facultative rela- tionships. The fact that microfilariae are rarely found in human blood or are absent there may be associated with the removal of developing dirofilariae from humans in earlier than the...

Description
Summary:	The ability of D. repens to complete its ontogenesis in man points to their obligate, rather than facultative rela- tionships. The fact that microfilariae are rarely found in human blood or are absent there may be associated with the removal of developing dirofilariae from humans in earlier than they achieve sexual maturity. Facultative ecological relationships to mosquitoes may be one of the reasons for limitation of human invasion cases. However, in long-standing microfilaremia in man (an obligate host), D.repens may take part in the epidemiological chain of dirofilariasis as a source of invasion.
