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.
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.
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.
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]
Symptoms and diseases [ edit ] Lab mice previously infected with N. brasiliensis develop massive emphysema with dilation of distal airspaces due to the loss of alveolar septa; N. brasiliensis infection can result in deterioration of the lung, destruction to the alveoli, and long-term airway hyperresponsiveness, which is consistent with ...
As shown in the CDC life cycle, oncospheres hatch and then penetrate the intestinal wall. [7] Rodents can become infected when they eat arthropods. Humans, especially children, can ingest the arthropods as well and therefore become infected via the same mechanism. Rodents, especially rats, are definitive hosts and natural reservoirs of H ...
Currently, there is no definitive treatment for P. tenuis in mammals, though research is still being conducted. The use of anthelmintics (ivermectin and fenbendazole) have been attempted in white-tailed deer. The results indicate, however, that ivermectin was ineffective against larvae that had already reached the spinal cord. [26]
Schistosoma japonicum is an important parasite and one of the major infectious agents of schistosomiasis.This parasite has a very wide host range, infecting at least 31 species of wild mammals, including nine carnivores, 16 rodents, one primate (human), two insectivores and three artiodactyls and therefore it can be considered a true zoonosis.
