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]
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.
These three types of T. gondii have differing effects on certain hosts, mainly mice and humans due to their variation in genotypes. [90] Type I: virulent in mice and humans, seen in people with AIDS. Type II: non-virulent in mice, virulent in humans (mostly Europe and North America), seen in people with AIDS.
Transmission electron micrograph of the Sin Nombre virus, the virus responsible for the outbreak. The spherical particles are virus bodies (virions). The 1993 Four Corners hantavirus outbreak was a disease outbreak caused by a hantavirus that occurred in the Four Corners region of the US states in Arizona, Colorado, and New Mexico.
In an animal study, researchers found that mice given a drug to inhibit a protein associated with aging lived nearly 25% longer and were less likely to develop cancer than mice in the control group.
Rat-bite fever (RBF) is an acute, febrile human illness caused by bacteria transmitted by rodents, in most cases, which is passed from rodent to human by the rodent's urine or mucous secretions. Alternative names for rat-bite fever include streptobacillary fever, streptobacillosis, spirillary fever, bogger, and epidemic arthritic erythema.
More than ten genetic types of Leptospira cause disease in humans. [13] Both wild and domestic animals can spread the disease, most commonly rodents. [8] The bacteria are spread to humans through animal urine or feces, or water or soil contaminated with animal urine and feces, coming into contact with the eyes, mouth, nose or breaks in the skin ...
Osteophagy in humans would be considered a form of pica. Unlike calcium and phosphorus in most animals, pica is associated with iron deficiencies in humans. [21] Humans are unlikely to suffer from calcium and phosphorus deficiencies because the minerals are widely abundant in the foods they consume. [22]
