Muspicea borreli Sambon, 1925

Muspicea borreli was discovered in 1911 by Professor A. Borrel, Director of the Bacteriological Institute of Strasbourg, while investigating the role of parasites in the genesis of cancer. The nematode was described by Sambon (1925) on the basis of seven female specimens from the subcutaneous connective tissue and inguinal glands of the common mouse, Mus musculus (Spratt et al., 2002).

Morphology and Anatomy:

Hermaphrodite:

Muspicea borreli is a protandrous hermaphrodite, spermatogenesis occurs in the wall of the genital pouch and terminates when ovogenesis commences by cell division commences in the distal region of the genital cord.
The vulva is atrophied and eggs hatch inside a uterine pouch, develop simultaneously to third-stage larvae and burst from the head region killing the adult (semelparity and endotokia matricida (Seurat, 1914)) providing an efficient mechanism for auto-reinfection of the host.

Life Cycle:

Muspicea borreli is a protandrous hermaphrodite, spermatogenesis occurs in the wall of the genital pouch and terminates when ovogenesis commences by cell division commences in the distal region of the genital cord.
The vulva is atrophied and eggs hatch inside a uterine pouch.
Eggs develop simultaneously to third-stage larvae.
Simulateous eruption of third stage juveniles from the hermaphrodite body through endotokia matricida provides an efficient mechanism for auto-reinfection of the host.
Cannibalism among hosts, (i.e. necrophagy), cutaneous penetration, lactation and grooming have been suggested as routes of infection.
Larvae are believed to penetrate the skin, develop in the subcutaneous tissues and transmission stages are thought to leave through a skin lesion and seek a new host.. A tissue migration would become necessary when percutaneous transmission was replaced by oral transmission as may occur in Muspicea (Spratt et al., 2002).
