RESUMO
Species of Philophthalmus parasitize primarily the eyes of wild and domestic birds. A variety of mammals, including humans, occasionally serve as the intermediate as well as the definitive hosts for this parasite, although human cases are extremely rare. Here, we report a case of human conjunctivitis caused by an infection with Philophthalmus sp. in Mexico. The patient was a 31-yr-old male who visited an ophthalmologist in Los Mochis, Sinaloa, Mexico, because of a foreign-body sensation in his left eye for 2 mo. A small live parasite was found in the connective tissue of the bulbar conjunctiva and was removed surgically under local anesthesia under ophthalmoscopic observation. The parasite was identified morphologically as Philophthalmus lacrimosus Braun, 1902. This is the first case of human philophthalmosis in Mexico and, to our knowledge, the first human case of P. lacrimosus infection in the world.

Gnathostomiasis is an important food-borne parasitic zoonosis that is endemic mainly in Asian countries where some people prefer to eat raw freshwater fish. In North America, the first recorded case of gnathostomiasis was in Mexico in 1970, and the numbers of gnathostomiasis patients in Mexico seems to be increasing dramatically with time. However, the epidemiology of this disease in Mexico has never been described in detail. Here we review the current status of gnathostomiasis in Mexico.

Campechetrema herrerai n. gen, n. sp. is described from the cichlid fish Petenia splendida from EI Vapor lagoon, an oligohaline lagoon, Campeche, México. It is distinguished from other genera of Cryptogoniminae by the presence of a single gonotyl, a preequatorial acetabulum, few vitelline follicles, and lack of pars prostatica and prepharynx.

The lung fluke Paragonimus mexicanus infects opossums in the state of Colima, on the Pacific coast of Mexico. Some of the hydrobiid snails occurring in the same area, and identified as Aroapyrgus alleei Morrison, 1946, were found naturally infected with rediae and cercariae of P. mexicanus. The morphology of A. alleei is here described and compared to that of other species of Aroapyrgus, which are actual or potential hosts of lung flukes in other enzootic or endemic areas in Central and South America.
