“…Pets can be also infested with D. gallinae, including canaries [12] which for the first time we report here as source of human infestations, such as previously recorded for pet gerbils [13]. The meaning of these mites in public health also stems from their role as potential allergens and reservoirs/vectors of zoonotic pathogens [14]; recently, Bartonella quintana and both Lyme Disease and Q Fever agents have been detected in Dermanyssus mite species collected from urban outbreaks of human dermatitis [15,16].…”

Avian mite dermatitis is a skin affliction of mammals, including humans caused by bites of nidicoulous, haematophagous mites in the suborder Mesostigmata, which naturally parasitize birds. The red-mite, Dermanyssus gallinae is the most common species implicated in episodes of dermatitis in city-dwellers, worldwide. Symptoms manifest in the form of pruritic, erythematous papules on exposed/covered body areas. We report 20 urban outbreaks of red-mite dermatitis occurring in Southern Italy from 2001 to 2017 (June) and diagnosed through parasitological identification by veterinarian entomologists. The patients, a total of 54 subjects, were infested in their homes/ workplaces by both mites emigrating indoors from deserted nests of sinantropic birds close to the infested edifices and from pet canaries. Red-mites may be the explanation of cases of pruriginous dermatitis of obscure origin in citydwellers. The applying of the One Health approach is crucial for diagnosis, treatment and prevention of dermatitis by epizoonotic ectoparasites.

“…Itch can alert the host to the presence of a tick and cause its removal prior to pathogen transmission. Tick-associated itch reactions are well recognized in people and especially those who develop immunoglobulin E antibody (Alexander 1986, Beaudouin et al 1997, Fisher et al 2006. The abundant basophils, eosinophils, and neutrophils that we noted in ticksensitized hosts have been shown to play a role in the development of itch reactions (Gill andWalker 1985, Alexander 1986).…”

Previous studies in rodents and people have demonstrated that repeated tick exposure is associated with reduced Borrelia burgdorferi transmission but the mechanism of prevention remains unclear. We examined the acute histopathologic reactions to initial and repeated Ixodes scapularis bites in BALB/c mice and in people. Skin biopsies of BALB/c mice infested for the first time by I. scapularis nymphs revealed vascular dilatation and an accumulation of inflammatory cells adjacent to the bite site but absent at the site of tick attachment. Such changes would enhance tick-borne pathogen transmission. Mice reexposed to I. scapularis nymphs experienced a decrease in vascular dilatation and a marked increase in inflammatory cells at the site of tick attachment. Skin biopsies of people with attached I. scapularis nymphs revealed similar histologic patterns. These results indicate that cellular changes at the tick-dermal interface following I. scapularis attachment are likely to allow for successful transmission of tick-borne pathogens in non-tick-immune hosts and to inhibit tick-borne pathogen transmission in hosts that have developed tick immunity.

“…The fact that the responses to A. americanum are so persistent and so profoundly pruritic suggests that a significant immune response is occurring at the site of the bite [17]. A recent report of multiple pruritic papules caused by Haemaphysalis longicornis in Korea demonstrated abundant eosinophils at the sites of the bites [18].…”

Purpose of review A novel form of anaphylaxis has been described that is due to IgE antibody (Ab) directed against a mammalian oligosaccharide epitope, galactose-alpha-1, 3-galactose (alpha-gal). Ongoing work regarding the cause and distribution of this IgE response is reviewed. Recent findings Our recent work has identified a novel IgE Ab response that has been associated with two distinct forms of anaphylaxis: immediate-onset anaphylaxis during first exposure to intravenous cetuximab and delayed-onset anaphylaxis 3–6 h after ingestion of mammalian food products (e.g. beef and pork). Further studies strongly suggested that tick bites were a cause, if not the only significant cause, of IgE Ab responses to alpha-gal in the United States and internationally. Summary Large numbers of patients with IgE Ab to alpha-gal continue to be identified in the USA and globally. Clinicians should be aware of this IgE response as the reactions often appear to be idiopathic because of the significant delay between eating mammalian meat and the appearance of symptoms.
