Caballerorhynchus is a monotypic genus of acanthocephalans (thorny-headed or spiny-headed parasitic worms) containing a single species, Caballerorhynchus lamothei, that infests animals.

Taxonomy

The species was described by Salgado-Maldonado in 1977. The National Center for Biotechnology Information does not indicate that any phylogenetic analysis has been published on Caballerorhynchus that would confirm its position as a unique order in the family Cavisomidae. [2] It has been suggested that the genus be moved to Rhadinorhynchidae due to their morophological similarities. [3]

Description

C. lamothei consists of a proboscis covered in hooks arranged in three circles with six hooks in each circle, a proboscis receptacle, and a trunk. [1] It is distinguished from other genera of Cavisomidae through several morphological traits including the location of the testes (away from posterior extremity). [4] [5] [6]

Distribution

The distribution of C. lamothei is determined by that of its hosts. It was found in the Sontecomapan Lagoon located in Veracruz, Mexico. [1] It is found in other locations. [7] [8] [9]

Life cycle of Acanthocephala.

The life cycle of an acanthocephalan consists of three stages beginning when an infective acanthor (development of an egg) is released from the intestines of the definitive host and then ingested by an arthropod, the intermediate host. An intermediate host of Caballerorhynchus is Discapseudes holthuisi . [12] When the acanthor molts, the second stage called the acanthella begins. This stage involves penetrating the wall of the mesenteron or the intestine of the intermediate host and growing. The final stage is the infective cystacanth which is the larval or juvenile state of an Acanthocephalan, differing from the adult only in size and stage of sexual development. The cystacanths within the intermediate hosts are consumed by the definitive host, usually attaching to the walls of the intestines, and as adults they reproduce sexually in the intestines. The acanthor are passed in the feces of the definitive host and the cycle repeats. There may be paratenic hosts (hosts where parasites infest but do not undergo larval development or sexual reproduction) for Caballerorhynchus. [13]

C. lamothei parasitizes the Irish mojarra (Diapterus auratus). [1] It was also found in Diapterus rhombeus , [14] Eugerres plumieri [15] and the southern catfish. [16] There are no reported cases of C. lamothei infesting humans in the English language medical literature. [11]

<i>Gigantorhynchus</i> Genus of parasitic worms

Gigantorhynchus is a genus of Acanthocephala that parasitize marsupials, anteaters, and possibly baboons by attaching themselves to the intestines using their hook-covered proboscis. Their life cycle includes an egg stage found in host feces, a cystacanth (larval) stage in an intermediate host such as termites, and an adult stage where cystacanths mature in the intestines of the host. This genus is characterized by a cylindrical proboscis with a crown of robust hooks at the apex followed by numerous small hooks on the rest of the proboscis, a long body with pseudosegmentation, filiform lemnisci, and ellipsoid testes. The largest known specimen is the female G. ortizi with a length of around 240 millimetres (9.4 in) and a width of 2 millimetres (0.08 in). Genetic analysis on one species of Gigantorhynchus places it with the related genus Mediorhynchus in the family Gigantorhynchidae. Six species in this genus are distributed across Central and South America and possibly Zimbabwe. Infestation by a Gigantorhynchus species may cause partial obstructions of the intestines, severe lesions of the intestinal wall, and may lead to death.

Intraproboscis is a monotypic genus of acanthocephalans that infest African black-bellied pangolin in the Central African Republic. Its body consists of a proboscis armed with hooks which it uses to pierce and hold the gut wall of its host, and a long trunk. It contains a single species, Intraproboscis sanghae. This genus resembles species in the genus Mediorhynchus but is characterized by infesting a mammal instead of birds, and having a simple proboscis receptacle that is completely suspended within the proboscis, the passage of the retractor muscles through the receptacle into the body cavity posteriorly, absence of neck, presence of a parareceptacle structure, and a uterine vesicle. The proboscis is armed with 34–36 rows of 6 to 7 hooks anteriorly and 15–17 spinelike hooks posteriorly which are used to attach themselves to the intestines of the host. The female worms are up to 180 millimetres long, virtually all of which is the trunk, and 2 millimetres wide.
