Nematode Parasites of Vertebrates of East Pakistan: Iv. Ascaroid Nematodes From Amphibia, Birds, and Mammals

Abstract

Three new species, Porrocaecum (P.) haliasturi sp. nov., Aplectana agubernaculum sp. nov., and A plectana asiatica sp. nov., are described from Dacca, East Pakistan, and four species, Contracaecum (C.) haliaëti (Baylis and Daubney, 1923), Heterakis spumosa (Schneider, 1866), Heterakis beramporia (Lane, 1914), and Meteterakis govindi (Karve, 1930) Inglis, 1957, redescribed. Toxocara mystax (Zeder, 1800) and Heterakis gallinae (Gmelin, 1790) Freeborn, 1923 are recorded from the domestic cat and fowl.

Reappraising the exteriorization of the mammalian testes through evolutionary physiology

“…Although it has been proposed that the abdominal cavity shifts and the testes is held in a generally rigid position by the gubernaculum, there is direct evidence that transabdominal testicular movement occurs as a combined push and pull interchange [24,104]. Crucially, the gubernaculum, which is more developed in the male fetus compared to the female provides a uniform trans-species pathway of testicular descent [105]. The female gubernaculum also assists ovarian descent and becomes the round ligament of the uterus as vestigial remnants.…”
