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.
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.
If an animal is suspected of lungworm infection, there are many ways to detect this parasitic infection such as performing one or more of the following techniques: a complete medical history including lung auscultation (stethoscope examination), doing a chest X ray, fecal examination for detection of ova or larvae, examination of respiratory ...
Ornithonyssus bacoti (also known as the tropical rat mite and formerly called Liponyssus bacoti) is a hematophagous parasite. [1] It feeds on blood and serum from many hosts. [2] [3] O. bacoti can be found and cause disease on rats and wild rodents most commonly, but also small mammals and humans when other hosts are scarce.
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 ]
The short-tailed bandicoot rat is a nocturnal rodent and spends most of its time in a burrow which comprises many tunnels and chambers. The depths may be up to 60 cm and the burrow may be up to 9 m long, covering an area of up to 120 m 2. One chamber is lined with vegetation for nesting. [3] The gestation period is believed to be about 17 days. [6]
The natural reservoir of infection, a small rodent known locally as ratón maicero ("maize mouse"; Calomys musculinus), has chronic asymptomatic infection, and spreads the virus through its saliva and urine. Infection is produced through contact of skin or mucous membranes, or through inhalation of infected particles.
