Chronic fatigue syndrome (CFS) in human patients remain a controversial and perplexing condition with emerging zoonotic aspects. Recent advances in human medicine seem to indicate a bacterial etiology and the condition has already been described in horses, dogs, cats and birds of prey in association with micrococci-like organisms in the blood. To evaluate(More)
A great deal of controversy and speculation surrounds the etiology of Chronic Fatigue Syndrome (CFS) in human patients and the existence of a similar illness in animals. To evaluate the association with a presumptive staphylococcal infection and bacteremia, seven dogs and eight cats diagnosed with CFS (two meeting the CDC working case definition) were(More)
Cutaneous dirofilariasis is a parasitic disease caused by the mosquito-borne filarial nematodes Dirofilaria (Nochtiella) repens, living in the subcutaneous tissue of dogs, cats, wild carnivores, and humans. Cases have been recently reported also from Germany, Czech Republic, Hungary, Ukraine, Russia, Austria, Switzerland, France, The Netherlands, and the(More)
Fifteen cats from Italy with Ehrlichia-like inclusion bodies in their neutrophils were studied. They were diagnosed with Anaplasma (Ehrlichia) phagocytophilum infection on the basis of cytological observation of morulae within 1 to 21 per cent of their neutrophils, clinical signs characteristic of ehrlichiosis and their response to doxycycline. The(More)
A pruritic dermatitis characterized by the presence of erythema, papules, focal or multifocal alopecia, crusting and nodules was seen in 28 dogs with Dirofilaria repens microfilariae infestation in an endemic area in north-west Italy. Previous unsuccessful nonspecific antipruritic treatments, flea control and restricted diet were recorded in 53.6% of the(More)
A report from England has suggested that Chronic Fatigue Syndrome exists in equines and constitutes an emerging veterinary problem. Preliminary epidemiological studies seem to confirm the zoonotic implications of CFS. An arsenical drug, sodium thiacetarsamide, was administered to four horses with a diagnosis of Chronic Fatigue Syndrome (CFS), already(More)
The presence of microfilariae of the zoonotic nematode Dirofilaria repens is reported in three dogs from Saudi Arabia, manifesting as pruritic dermatitis with signs including erythema, alopecia, papules, crusting and hyperkeratosis. All dogs were found to have concurrent babesiosis. Specific treatments against the two conditions led to complete clinical(More)
Chronic fatigue and immune dysfunction syndrome (CFIDS) is a recognized human illness with zoonotic implications that is rarely described in animals. Eight birds of prey examined between 1992 and 1995 and sharing common symptoms (asthenia, inability to fly, poor appetite and emaciation) underwent laboratory tests revealing immunodeficiency, anaemia, high(More)
Pruritic dermatitis associated with Dirofilaria (Nochtiella) repens microfilariae in the blood was diagnosed in 22 dogs from Fermo (Central Italy). According to the history, previous unsuccessful treatments with corticosteroids, antibiotics, restricted diet, flea control, levamisole and ivermectin were recorded in 17 dogs (77.3%). The combined filtration(More)
Trypanosoma evansi (Steel, 1885) is a protozoal parasite of mammalian blood which is transmitted mechanically by biting flies of the genera Tabanus, Lyperosia, Stomoxys and Atylotus [4]. There is no intermediate host. Carnivores may be also affected after feeding on infected meat [11]. T. evansi is pathogenic in most domesticated animals and some wild(More)
