“…An in house ELISA for detection of antibodies to ER in chicken serum was set up based on an earlier described protocol [15]. For production of coating antigen ER was cultured for 48 h on horse blood agar and colonies were subsequently suspended in 0.05 M Na 2 CO 3 /NaHCO 3 buffer, pH 9.6, and sonicated at 1.2 A, 10 µm amplitude, for 5 min on ice.…”

Erysipelas, a disease caused by Erysipelothrix rhusiopathiae (ER), is an increasing problem in laying hens housed in cage-free systems. This study aimed to monitor immune responses during ER infection of naïve chickens and chickens vaccinated intra muscularly with a commercial inactivated ER vaccine. Chickens were infected intra muscularly with ER at 30 days of age and blood leukocyte counts, serum levels of mannose binding lectin (MBL) and ER-specific IgY were monitored until the experiment was terminated at day 15 after infection. ER was detected in blood from more chickens and at higher bacterial counts in the naïve group (day 1: 1 of 7 chickens; day 3: 6 of 6 chickens) than in the vaccinated group (day 1: 0 of 7 chickens; day 3: 1 of 6 chickens). During the acute phase of infection transient increases in circulating heterophil numbers and serum MBL levels were detected in all ER infected chickens but these responses were prolonged in chickens from the naïve group compared to vaccinated chickens. Before infection IgY titers to ER in vaccinated chickens did not differ significantly from those of naïve chickens but vaccinated chickens showed significantly increased IgY titers to ER earlier after infection compared to chickens in the naïve group. In conclusion, the ER infection elicited prompt acute innate responses in all chickens. Vaccinated chickens did not have high IgY titers to ER prior to infection but did however show lower levels of bacteraemia and their acute immune responses were of shorter duration.

“…This means that most physicians are unfamiliar with the diagnosis of several less common mite-related forms of dermatitis, including the dermatitis caused by D. gallinae (Cafiero et al, 2008;Haag-Wackernagel & Bircher, 2010;Collgros et al, 2013). This is extremely important, not only because misdiagnosis may lead to failure in the treatment of patients, but also because, as underlined above, D. gallinae may be a vector/reservoir of ascertained zoonotic agents (Chirico et al, 2003;Valiente Moro et al, 2009;Brännström et al, 2010;Circella et al, 2011;Melter et al, 2012;Raele et al, 2018).…”

Dermanysuss gallinaeattacks humans. Mind the gap!

Dermanyssus gallinae is a haematophagous ectoparasite primarily known as a pest of domestic and wild birds. It occasionally feeds on a range of mammals, and, more importantly, is of growing concern in human medicine. This review highlights mite attacks on people working with poultry, and updates the increasing incidence of dermanyssosis in urban environments in Europe. Although several cases of dermanyssosis have been documented, there are a number of reasons why diagnosis of D. gallinae infestations in humans is likely to be underestimated. Firstly, medical specialists are not well aware of D. gallinae infestations in humans. There is also a lack of collaboration with specialists from other disciplines. The problem is compounded by misdiagnoses and by the lack of diagnostic tools. We review the literature on human dermanyssosis cases in Europe, and also provide information on the epidemiology, clinical, histo-pathological and immunological aspects of dermanyssosis. We stress the need for improved recognition of this challenging infestation in humans, and provide straightforward recommendations for health practitioners, starting with collection of the correct anamnestic information and including appropriate management methods for case recognition and resolution. Finally, we indicate the most urgent areas to be addressed by future research. RESEARCH HIGHLIGHTS. Dermanyssus gallinae is of growing concern in human medicine.. Most physicians are not well aware of dermanyssosis in humans.. Bio-epidemiological and clinical aspects of this ectoparasitosis are highlighted.. Practical key actions for diagnosis and correct management of infestation in humans are provided.

“…E. rhusiopathiae, the causative agent of erysipelas, and S. gallinarum, causing fowl typhoid, were reported in the poultry red mite, D. gallinae (Zeman et al 1982;Chirico et al 2003;Wales et al 2010;Brännström et al 2010;Valiente-Moro et al 2011). In terms of veterinary importance, mites have been reported as potential vectors and reservoirs of several pathogenic bacteria of livestock.…”

A dataset of bacterial diversity found in mites was compiled from 193 publications (from 1964 to January 2015). A total of 143 mite species belonging to the 3 orders (Mesostigmata, Sarcoptiformes and Trombidiformes) were recorded and found to be associated with approximately 150 bacteria species (in 85 genera, 51 families, 25 orders and 7 phyla). From the literature, the intracellular symbiont Cardinium, the scrub typhus agent Orientia, and Wolbachia (the most prevalent symbiont of arthropods) were the dominant mite-associated bacteria, with approximately 30 mite species infected each. Moreover, a number of bacteria of medical and veterinary importance were also reported from mites, including species from the genera Rickettsia, Anaplasma, Bartonella, Francisella, Coxiella, Borrelia, Salmonella, Erysipelothrix and Serratia. Significant differences in bacterial infection patterns among mite taxa were identified. These data will not only be useful for raising awareness of the potential for mites to transmit disease, but also enable a deeper understanding of the relationship of symbionts with their arthropod hosts, and may facilitate the development of intervention tools for disease vector control. This review provides a comprehensive overview of mite-associated bacteria and is a valuable reference database for future research on mites of agricultural, veterinary and/or medical importance.
