Infection pattern of the spirurid nematode Protospirura numidica criceticola in the cricetid rodent Akodon azarae on poultry farms of central Argentina
The nematode Protospirura numidica criceticola infects the stomach of Neotropical cricetid rodents when they ingest infected arthropods. In North America, prevalence values fluctuated, showing marked peaks in desert habitats, while remaining low in humid environments. The infection pattern has not b...

It was not related to the abundance of A. azarae (r s = 0.37) or to rainfall. In this humid region of Argentina, where food resources are diverse throughout the year, the omnivorous A. azarae may have a variable diet so that infection can occur in the four seasons.

Only 3.8% of the rodents were parasitized with three or more specimens of the parasite, and that was only in autumn. It is suggested that rodents can not overwinter successfully with a heavy biomass of stomach parasites. © 2008 Cambridge University Press. Fil:Miño, M.H. Universidad de Buenos Aires.

The nematode Protospirura numidica criceticola infects the stomach of Neotropical cricetid rodents when they ingest infected arthropods.
