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]
Haverhill fever (or epidemic arthritic erythema) is a systemic illness caused by the bacterium Streptobacillus moniliformis, an organism common in rats and mice. If untreated, the illness can have a mortality rate of up to 13%. Among the two types of rat-bite fever, Haverhill fever caused by Streptobacillus moniliformis is most common in North ...
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.
Rat-bite symptoms are visually seen in most cases and include inflammation around the open sore. A rash can also spread around the area and appear red or purple. [1] Other symptoms associated with streptobacillary rat-bite fever include chills, fever, vomiting, headaches, and muscle aches. Joints can also become painfully swollen and pain can ...
Scientists have some good news for rats and some bad news for city dwellers. Rat populations are rising in cities including Washington, D.C., and San Francisco, reports a study released Friday ...
Burgeoning rat populations are a big problem for cities. Rats damage infrastructure, contaminate food, and can start fires by gnawing through wires. They cause an estimated $27 billion of damage ...
Leptospirosis is a blood infection caused by the bacterium Leptospira [8] that can infect humans, dogs, rodents and many other wild and domesticated animals. [8] Signs and symptoms can range from none to mild (headaches, muscle pains, and fevers) to severe (bleeding in the lungs or meningitis). [5]
The risk of human infection from H. diminuta is very low, since its main host is the rat. Also known as the rat tapeworm, H. diminuta adults live and mate in the bowels of rats. Eggs of H. diminuta are excreted by the rats in droppings, which are frequently consumed by beetles. Once inside the beetle, the eggs mature into a cysticercoid.
