Abstract
This small compendium on the pathogenic and non-pathogenic filariae of man will be useful primarily to the physician who may see patients harboring filarial infections outside endemic areas. An introductory chapter on orientation includes a brief description of each of the pathogenic species, viz., Wuchereria bancrofti, Brugia malayi, Onchocerca volvulus, Loa loa and Dracunculus medinensis, the last of which is a filariate but not a filarioid nematode; likewise the species not usually regarded as pathogenic, viz., Dipetalonema perstans, D. streptocerca and Mansonella ozzardi. Each is considered from the anatomical relationship of the adult stage of the parasite to the human host, whether or not it produces microfilarial embryos, the life cycle of the species (with helpful diagrams), and its geographical distribution (presented with maps under the topic “Diagnostic”).Diagnosis for each of the pathogens includes typical and atypical signs and symptoms, with illustrations of the principal pathologic patterns, method of examination of the patient (including pyelography and lymphography in suspected cases of Bancroftian and Malayan infection), and microscopic examination of blood and tissue juices.
