First described by Chinese parasitologist Hsin-Tao Chen (1904–1977) in 1935, after examining Cantonese rat specimens, [1] the nematode Angiostrongylus cantonensis was identified in the cerebrospinal fluid of a patient with eosinophilic meningitis by Nomura and Lim in Taiwan in 1944.
Preventing rodents from entering one's house, removing potential nesting sites around one's house, [25] sweeping areas likely inhabited by rodents, [3] covering trash cans, cutting grass, spraying water to prevent dust prior to activities, and installing public warning signs in endemic areas can help to reduce contact with rodents.
Angiostrongyliasis is an infection by a roundworm of the Angiostrongylus type. Symptoms may vary from none to mild, to meningitis. [1]Infection with Angiostrongylus cantonensis (rat lungworm) can occur after ingestion of raw or undercooked snails or slugs, and less likely unwashed fruits and vegetables.
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
The hairs in this area are, at the tips, like ordinary hair, but are otherwise spongy, fibrous, and absorbent with a honeycomb structure. [4] The rat is known to deliberately smear these hairs with poison from the bark of the Acokanthera schimperi , the poison arrow tree, on which it chews, thus creating a defense mechanism that can sicken or ...
Hymenolepis microstoma is an obligate parasite.Adults live in the bile duct and small intestine of rodents such as mice (Mus musculus), and larvae infect grain beetles such as Tribolium spp., in which they metamorphose from larvae into juvenile worms. [3]
Rodent mite dermatitis (also known as rat mite dermatitis) is an often unrecognized ectoparasitosis occurring after human contact with haematophagous mesostigmatid mites that infest rodents, such as house mice, [1] rats [2] and hamsters. [3]
Forty percent of mammal species are rodents, and they inhabit every continent except Antarctica. This list contains circa 2,700 species in 518 genera in the order Rodentia. [ 1 ]
