“…During the night, mites search for their preferential hosts (wild and domestic rodents) to obtain a blood meal and are generally not active during daylight hours. If suitable preferential hosts are unavailable, the mites occasionally infest alternative hosts, such as dogs and humans (Charlesworth and Clegern 1977, Theis et al, 1981, Lopatina et al 1992, Chung et al 1998, Skirnisson 2001, Beck and Pfister 2004. The bite of these mites often causes tiny, clear blisters that are accompanied by a rash.…”

“…The bite of these mites often causes tiny, clear blisters that are accompanied by a rash. There are multiple articles from around the world that describe human infestation with O. bacoti, (Charlesworth andClegern 1977, Beck andPfister 2004), in Moscow (Lopatina et al 1992), in Iceland (Skirnisson 2001, and in America (Chung et al 1998); however, only recently have investigators described the potential for disease transmission by Dermanyssus spp. mites.…”

After raccoons were trapped and removed from under a house in New York, the owner and her two Papillon dogs became infested with numerous rat mites (Ornithonyssus bacoti). Two weeks later, both dogs developed pruritus, progressively severe vesicular lesions, focal areas of skin exfoliation, swelling of the vulva or prepuce, abdominal pain, and behavioral changes. Two months after the mite infestation, the owner was hospitalized because of lethargy, fatigue, uncontrollable panic attacks, depression, headaches, chills, swollen neck lymph nodes, and vesicular lesions at the mite bite sites. Due to ongoing illness, 3 months after the mite infestation, alcohol-stored mites and blood and serum from both dogs and the owner were submitted for Bartonella serology and Bartonella alpha Proteobacteria growth medium (BAPGM) enrichment blood culture/PCR. Bartonella henselae DNA was amplified and sequenced from blood or culture specimens derived from both dogs, the owner, and pooled rat mites. Following repeated treatments with doxycycline, both dogs eventually became B. henselae seronegative and blood culture negative and clinical signs resolved. In contrast, the woman was never B. henselae seroreactive, but was again PCR positive for B. henselae 20 months after the mite infestation, despite prior treatment with doxycycline. Clinicians and vector biologists should consider the possibility that rat mites may play a role in Bartonella spp. transmission.

“…bacoti , the tropical rat mite, is a hematophagous mite that can be found on a variety of wild and captive small mammals and birds worldwide. 455 The mite is also the intermediate host for the fi larial nematode Litomosoides carinii , which can potentially act as a vector of murine typhus, Q fever, Chagas ' disease, and Coxsackie virus; however, it is thought that this is of minimal relevance for natural transmission of infection. Pet rodents can be infected, from inapparent to pruritic with excoriation.…”

Companion Animal Zoonoses

Companion animals can harbor a wide range of parasites, some of which are transmissible to humans. The overall burden of human diseases attributable to companion animal -associated parasites is unknown and varies greatly between regions. The risks associated with some are often overstated while others are largely ignored, and the range of illness can extend from mild and selflimited to fatal.

“…Some species of gamasid mite have been suspected to be potential vectors or reservoir hosts of haemorrhagic fever with renal syndrome (HFRS), also called epidemic haemorrhagic fever (EHF), and some other zoonoses (Deng et al, 1993;Song, 1999;Huang & Guo, 2010). In addition, direct parasitism and the biting of some gamasid mites can cause acariasis and skin anaphylaxis (Zemskaya, 1973;Chung et al, 1998;Rosen et al, 2002;Adler & Wills, 2003). The human louse Pediculus humanus humanus (Phthiraptera: Pediculidae) is a subspecies of sucking louse (suborder Anoplura) and is the vector of epidemic typhus (Rickettsia prowazeki), epidemic relapsing fever (Borellia recurrentis) and trench fever (Rickettsia quintana) (Guo et al, 2004a(Guo et al, , 2004bBrouqui & Raoult, 2006;Pittendrigh et al, 2006;Yassina et al, 2008).…”

The Yunnan red-backed vole Eothenomys miletus (Rodentia: Cricetidae) is an endemic rodent species and reservoir host of zoonoses in southwest China. Based on a large host sample (2463 voles collected from 39 localities between 2001 and 2013), a general analysis of four categories of ectoparasite (fleas, sucking lice, chigger mites and gamasid mites) on E. miletus across its entire range of distribution was made. This analysis identified a total of 71 895 ectoparasites belonging to 320 species (30 species of flea, 9 of sucking louse, 106 of gamasid mite and 175 of chigger mite) with a high prevalence (87%), mean abundance (29.19) and mean intensity (33.69). Of the 18 vector species of zoonoses found on E. miletus, the flea Ctenophthalmus quadratus (Siphonaptera: Hystrichopsyllidae) and chigger mite Leptotrombidium scutellare (Trombidiformes: Trombiculidae) were the dominant species; these are the main vectors of zoonoses in China. All of the dominant parasite species showed an aggregated distribution pattern. Male voles harboured more species of parasite than females. Chigger mites represented the most abundant species group on voles and their prevalence was positively correlated with mean abundance (r = 0.73; P < 0.05). As a single rodent species, E. miletus has a high potential to harbour abundant ectoparasites with high species diversity and high rates of infestation. The sex of the vole affects ectoparasite infestation.

Outbreak of rat mite dermatitis in medical students

Abstract: Rat mite dermatitis can occur in clusters that involve a common source of exposure to the rat mite epidemiologically. Prompt identification of rat mites and the eradication of mites and rodents from the environment can prevent further spreading of the disease.
