“…akari together with O. tsutsugamushi are the rickettsial agents transmitted by mites. 107 The first clinical manifestation of this rickettsiosis is a primary papulovesicular lesion at the location of inoculation at 24-48 h after the bite. This primary lesion becomes an eschar, frequently associated with regional lymphadenopathy.…”

Rickettsioses share common clinical manifestations, such as fever, malaise, exanthema, the presence or absence of an inoculation eschar, and lymphadenopathy. Some of these manifestations can be suggestive of certain species of Rickettsia infection. Nevertheless none of these manifestations are pathognomonic, and direct diagnostic methods to confirm the involved species are always required. A syndrome is a set of signs and symptoms that characterizes a disease with many etiologies or causes. This situation is applicable to rickettsioses, where different species can cause similar clinical presentations. We propose a syndromic classification for these diseases: exanthematic rickettsiosis syndrome with a low probability of inoculation eschar and rickettsiosis syndrome with a probability of inoculation eschar and their variants. In doing so, we take into account the clinical manifestations, the geographic origin, and the possible vector involved, in order to provide a guide for physicians of the most probable etiological agent.

“…When its regular host is not available, the mite may attack other mammals or humans as accidental hosts, displaying ‘bite and run’ behaviour, as it cannot complete its life cycle on the human body 3 . The cases documented in humans have resulted from occupational exposure, 5,6 direct contact with the bird or other infested pets, 3 proximity to infected areas (nests 4,7 and ventilation shafts 2 ) or airborne spread 1 …”

“…Treatment of the infestation essentially requires removal of the source of mites, and disinfection of the dwelling, clothes and linen using hot water and acaricides 4,8 . The patient should have a bath rather than a shower to ensure that mites are removed, and if required, symptomatic treatment with antihistamines and topical corticosteroids should be given 1 . The use of topical acaricides is controversial, because the mite does not live or reproduce on humans, but despite this, some authors recommend applying 1–5% topical permethrin 6 .…”

Dermanyssus gallinae(chicken mite): an underdiagnosed environmental infestation

et al. 2013

Dermanyssus gallinae is a mite that normally parasitizes small birds but may occasionally bite humans. We report an unusual case of an 82-year-old woman who presented with pruritus and bite-like lesions over her trunk. Other members of the household were also affected. On physical examination, mites < 1 mm in size were found on the patient's body. The family were residing in the city centre and had no pets, but there were pigeon nests in close proximity to the house. Most dermatologists have difficulties identifying ectoparasitosis. In the case of D. gallinae, the small size of the mites and the fact that they leave the host after feeding means that they may not be seen at presentation, thus such infestations are likely to be underdiagnosed. Physicians should be aware that infection with this mite is possible even in patients from urban areas, and it should be included in the differential diagnosis of conditions causing recurrent pruritus unresponsive to standard treatments.

“…Scabies is a major global health problem in human and animal populations (McClain et al 2009). Sarcoptic mange caused by Sarcoptes scabiei var cameli is a widespread, contagious and debilitating skin disease, ranking among the most serious and economically important diseases of the camel (Pegram and Higgins 1992).…”

Oxidative stress is an imbalance between radical-generating and radical-scavenging activity, resulting in oxidation products and tissue damage. This study was aimed to evaluate the status of oxidative stress indices in blood of camels naturally infested with S. scabiei. Forty-seven male camels (Camelus dromedaries) were divided according to the extent of the infested area with Sarcoptes scabiei into four groups, mild (MID, n = 12), moderate (MOD, n = 10), severely infested (SEV, n = 10) and healthy control group (n = 15). Blood was used for determination of red cell count (RBC), hemoglobin (Hb), packed cell volume (PCV), serum nitric oxide (NO(•), a free radical), ascorbate and albumin concentrations, and erythrocytic values of malondialdehyde (MDA, a marker of lipid peroxidation), protein carbonyls (PC, an indicator of protein oxidation), glutathione (GSH) superoxide dismutase (SOD) and catalase (CAT). Decreased levels (P < 0.05) of RBC, Hb, PCV, albumin and ascorbate were noticed in MOD and SEV compared to controls with the lowest values (P < 0.05) in SEV except for ascorbate, where MOD did not differ from SEV. Compared to controls, NO(•) gradually increased (P < 0.05) in MID followed by MOD and SEV, whereas MDA and PC were higher (P < 0.05) in MOD and SEV. PC was higher (P < 0.05) in MOD than SEV. In addition, the antioxidants GSH, SOD and CAT were higher (P < 0.05) in MID and lower (P < 0.05) in MOD and SEV compared to controls. GSH was lower (P < 0.05) in SEV compared to MOD. Besides, Hb was negatively correlated with NO(•) (r = -0.68, P < 0.001), MDA (r = -0.53, P < 0.001) and PC (r = -0.73, P < 0.001). In conclusion, dromedary sarcoptosis is accompanied by a state of oxidative stress process, which increased by increasing the area of infestation, and may contribute to the pathogenesis of the disease.
