“…[2] Two species, A. armillatus and Linguatula serrata, account for more than 99% of all reported human cases. [1] Among the four species of Armillifer, armillatus is found most commonly in West Africa, where the infection rate may be as high as 23% and the radiological incidence about 1.4%. [3] Infestation by A. armillatus was diagnosed radiologically in this woman.…”

Background: Diagnosis of Armillifer armillatus infestation is usually incidental, commonly via autopsy or radiography. Affected individual are usually asymptomatic. The case presented here, however, had severe thoracic and abdominal involvement with clinical manifestations. Aim: To report a case of heavy A. armillatus infestation in an adult female Nigerian rural dweller complicated by hepatic parenchyma damage. Setting: Case report from semi-urban southern Nigeria, using clinical records and imaging findings. Materials and Methods: Clinical case records, including laboratory results and radiographic /computed tomography images. Conclusion: Parenchymal damage with organ dysfunction can be seen with severe A. armillatus infestation. Thus, there is a need for regular health education regarding the risk of A. armillatus infestation for individuals who consume snake meat.

Sudden death due to disseminated porocephalosis — a case history

1992

An 18-year-old Nigerian girl died suddenly and unexpectedly from disseminated porocephalosis. The patient was hospitalised complaining of fever, dizziness, weakness and jaundice. Clinical examination revealed a restless, confused and hypotensive patient. She died within two hours of admission. Autopsy revealed disseminated Porocephalus armilatus infestation involving the thoracic and abdominal linings and their internal organs. The relationship between the disseminated parasitic involvement and the death of this girl is discussed.

“…In the past, pentastomidosis was considered to be a rare disease; however, the number of reported cases has increased significantly in recent years, which has lead to heightened concern within the medical profession. The optimal diagnostic techniques and therapeutic approach for pentastomidosis are still lacking, despite the fact this disease was initially described nearly 165 years ago [19]. Therefore, further research on pentastomids, the pathogens responsible for pentastomidosis, is urgently required to improve the prevention, diagnosis and treatment of this disease.…”

BackgroundPentastomiasis is a rare zoonotic disease caused by pentastomids. Despite their worm-like appearance, they are commonly placed into a separate sub-class of the subphylum Crustacea, phylum Arthropoda. However, until now, the systematic classification of the pentastomids and the diagnosis of pentastomiasis are immature, and genetic information about pentastomid nylum is almost nonexistent. The objective of this study was to obtain information on pentastomid nymph genes and identify the gene homologues related to host-parasite interactions or stage-specific antigens.Methodology/Principal FindingsTotal pentastomid nymph RNA was used to construct a cDNA library and 500 colonies were sequenced. Analysis shows one hundred and ninety-seven unigenes were identified. In which, 147 genes were annotated, and 75 unigenes (53.19%) were mapped to 82 KEGG pathways, including 29 metabolism pathways, 29 genetic information processing pathways, 4 environmental information processing pathways, 7 cell motility pathways and 5 organismal systems pathways. Additionally, two host-parasite interaction-related gene homologues, a putative Kunitz inhibitor and a putative cysteine protease.Conclusion/SignificanceWe first successfully constructed a cDNA library and gained a number of expressed sequence tags (EST) from pentastomid nymphs, which will lay the foundation for the further study on pentastomids and pentastomiasis.
