Investigation of Morphological Characteristics of Pubic lice (Pthirus pubis, Linnaeus, 1758)

Abstract

Pubic lice (Pthirus pubis) are obligate, permanent ectoparasites of humans, entirely dependent upon their vertebrate hosts for survival. Pubic lice have a very simplified body form as a result of their parasitic characteristics, being wingless and dorsoventrally flattened. In the study, the pubic lice taken from a male patient were examined morphologically in detail and their taxonomic characteristics were presented. The lice specimens were examined for morphological and taxonomic characteristics under a light microscope. The identification of the Pthirus pubis species was made by determining the height, anatomical body parts, dorsal and ventral morphological details of the adult male and female two pubic lice. Examined adult pubic lice were light cream-colored, 1-2 mm in length, and their anatomical structures included three pairs of legs, two prominent antennae, and parts of the thorax and abdomen in a combined structure. Pthirus pubis causes pediculosis pubis disease in humans. The disease can be sexually transmitted to humans. Pthirus pubis is spread primarily through person-to-person sexual contact. Pubic louse is a major public health problem that can be contagious among humans, and it has great importance to know their morphological characters to diagnose this ectoparasite and distinguish it from other insects.

Öz

Kasık bitleri (Pthirus pubis) hayatta kalmak için omurgalı konakçılara bağımlı, obligat ve daimi insan ektoparazitleridir. Kasık bitleri, kanatsız, dorsoventral olarak düz şekilli ve parazitik özelliklerinden dolayı çok basit yapıdırlar. Çalışmada, erkek bir hastadan alınan kasık bitlerinin ayrıntılı olarak morfolojik ve taksonomik özellikleri incelenerek sunulmuştur. Bit örnekleri morfolojik ve taksonomik özellikler açısından ışık mikroskobu ile incelendi. Pthirus pubis türünün tanımlanması, yetişkin erkek ve dişi iki kasık bitinin boyu, anatomik vücut bölümleri, dorsal ve ventral morfolojik detayları belirlenerek yapıldı. İncelenen erişkin kasık bitleri; açık krem renkli, boyları 1-2 mm aralığında, anatomik yapıları ise üç çift bacakları, iki belirgin anten taşıyan baş kısımları ile birleşik yapıdaki thorax ve abdomen bölümleri mevcut idi. Pthirus pubis, insanlarda pediculosis pubis hastalığına neden olur. Hastalık cinsel yolla insanlara bulaşmaktadır. Bu hastalık öncelikle kişiden kişiye cinsel ilişki yoluyla yayılmaktadır. Kasık bitleri insanlar arasında bulaşıcı olabilen önemli bir halk sağlığı sorunu olup, bu ektoparazitin tanısı ve diğer böceklerden ayırt edilmesi için morfolojik karakterlerinin bilinmesi büyük önem taşımaktadır
