Liponyssoides sanguineus (hematophagic-biting mite) is a mite of the rat, mouse, and other domestic rodents that occasionally bites man. Wild rodents are hosts to Liponyssoides sanguineus (house mouse mite), Laelaps echidnina (spiny rat mite), Laelaps pontiger (syn.

Among laboratory rodents, they usually parasitize the Norwegian rat Rattus norvegicus and black rat Rattus rattusbut they also readily infest mice.
Liponyssoides sanguineus – Wikipedia
The EPA reports no evidence of toxicity in nontarget species EPAbut it is advisable to avoid exposure of Drosophila melanogaster colonies and mice or cell lines that use ecdysone-inducible gene expression systems No et al. In addition, treatments should address potential locations for colonies of escaped rodents, such as inside poorly sealed animal facility doors, biosafety cabinets, and ventilation ducts.
Unlike barriers at the room or facility level that depend on limiting access to a few highly liponyssoidees individuals, barriers at the cage level allow facility access by multiple personnel while still protecting the laboratory rodents.
Close mobile search navigation Article navigation. To avoid reinfestation, they should treat all areas occupied by rodents or rodent equipment, including support areas, investigator laboratories, and procedure areas. Ten-year long monitoring of laboratory mouse and rat colonies in French facilities: Related articles in Web of Science Google Scholar.
It can transmit human disease,  is associated with causing rodent mite dermatitis in humans  and is noted for carrying Rickettsia akariwhich causes rickettsialpox. Optimal age at fostering for derivation of Helicobacter hepaticus -free mice. Researchers have also documented O. Use of permethrin eradicated the tropical rat mite Ornithonyssus bacoti from a colony of mutagenized and transgenic mice. Both males and females have a single dorsal shield thickened chitinous area ; males usually have one ventral shield and females three: Given the undesirability of insecticides, alternatives include physical methods such as silica-based products and biological methods such as insect growth regulators.
Regular health surveillance Livingston helps to detect excluded organisms, and liponysskides there be an outbreak, mites and pinworms are variously susceptible to treatment with parasiticides such as avermectins, pyrethroids, and benzimidazoles Baumans et al.
Cage barrier systems NRC are commonly used in research institutions as a means to exclude unwanted pathogens. Microbiological monitoring of laboratory mice lipoynssoides biocontainment in individually ventilated cages: Pigeon or chicken liponyssoodes may also harbor Ornithonyssus lioonyssoides or O.
A serologic survey for viruses and Mycoplasma pulmonis among wild house mice Mus domesticus in southeastern Australia. Mesostigmatid mites infest both rats and mice and, unlike the more common rodent fur mites MyobiaMyocoptesand Radfordia sp. They are only weakly sclerotized and semitransparent, appearing white when unengorged and red-brown when engorged.
Pyrethrin and pyrethroid insecticides. Dermacentor variabilis Dermacentor andersoni Amblyomma: In our institution, sticky insect traps were inefficient as a diagnostic tool; instead, in each of our outbreaks the diagnosis of mites came from animal handlers who had either been bitten or had observed the mites on themselves or on cage tops.
It is the vector for Rickettsialpox.
Mesostigmatid mites are present on wild rodents and thus may migrate to commensal rodents. Environmental application of silica aerogel has been effective for controlling rat mite infestations in homes Ebeling and, as it is not likely to have a research impact, could also be a candidate for environmental control of insect and mobile mite pests in laboratory animal facilities. Ornithodoros moubata Ornithodoros hermsi Ornithodoros gurneyi other: Mice carry pathogens sabguineus may remain undetected in barrier housing due to low prevalence and inefficient transmission to bedding sentinels Besselsen et al.
Mesostigmatid mites are a large order of highly mobile mites, class Ssnguineus, subclass Acari, order Mesostigmata. In view of the undesirability of insecticide use in the animal facility, it is advisable to investigate the effectiveness of preventive treatments, such sanguineks environmental application of insect growth regulators or silica-based products.
Successful rederivation of contaminated immunocompetent mice using neonatal transfer with iodine immersion. Evaluation of isolator caging systems for protection of mice against challenge with mouse hepatitis virus.
Oxford University Press is a department of the University of Oxford. Cross-fostering in combination with ivermectin therapy: Periodically they can also become a problem for laboratory rodent colonies, particularly when building construction or renovations disturb colonies of commensal building rodents that had been acting as snguineus.
Pathogen-free rodents are readily available from vendors, and widespread use of barrier caging systems in concert with sterilized equipment, high-efficiency particulate air HEPA — filtered air cabinets, protective clothing, and disinfection help keep pathogens out Brielmeier et al.
There is no published information on the use of insect growth regulators IGRs to prevent mesostigmatid mite infestations in animal facilities.
