RESUMO
Hemotropic mycoplasmas are associated with subclinical disease in dogs and should be identified in blood donors. The objective was to investigate the presence and effect of M. haemocanis in units of packed red blood cells (pRBC) during storage. Canine donors (n = 10) were screened for M. haemocanis by quantitative real-time PCR. pRBCs were obtained from 5 hemoplasma negative dogs and 5 hemoplasma positive dogs. Each pRBC was aliquoted into two 100 mL transfer bags and stored at 4 °C. M. haemocanis loads and biochemical variables (pH, bicarbonate, potassium, sodium, chlorite, glucose, lactate, ammonia, PCV, and % hemolysis) were evaluated on days 1, 7, 18, and 29. M. haemocanis loads increased in pRBC from day 1-29 of storage. Glucose decreased and lactate increase faster in pRBC with M. haemocanis. This study contributes to understand hemoplasma metabolism and reinforces that dog donors should be tested for hemoplasmas.

The hippoboscids are cosmopolitan permanent obligate hematophagous ectoparasites of birds, domestic and wild mammals and, occasionally, humans. Some species may act as vectors or hosts of etiological pathogenic agents. The aims of this study were to report on the first cases of Hippoboscidae in Crax blumenbachii and Parabuteo unicinctus; to provide new reports from Brazil on Tyto furcata and Asio stygius parasitized by Icosta americana; to report on individuals of Bubo virginianus, Falco sparverius and Accipiter striatus parasitized by genera Ornithoctona; and to provide new reports on parasitism of O. erythrocephala in the state of Rio Grande do Sul. The birds of prey and C. blumenbachii were attended at a rehabilitation center in Porto Alegre and at a veterinary hospital in Cruz Alta. These new records demonstrate the huge gap that exists regarding studies on avian ectoparasites and highlight potential vectors of hemoparasites for the bird species studied.

Resumo Os hipoboboscídeos são ectoparasitos hematófagos obrigatórios, permanentes e cosmopolitas de aves, mamíferos domésticos e silvestres e, ocasionalmente, humanos. Algumas espécies podem atuar como vetores ou hospedeiros de agentes patogênicos etiológicos. Os objetivos deste estudo foram relatar os primeiros casos de Hippoboscidae em Crax blumenbachii e Parabuteo unicinctus; fornecer novo relato do Brasil sobre Tyto furcata e Asio stygius parasitados por Icosta americana; relatar indivíduos de Bubo virginianus, Falco sparverius e Accipiter striatus parasitados pelo gênero Ornithoctona; e fornecer novos relatos sobre parasitismo de O. erythrocephala no estado do Rio Grande do Sul. As aves de rapina e C. blumenbachii foram atendidas em um centro de reabilitação em Porto Alegre e em um hospital veterinário em Cruz Alta. Esses novos registros demonstram a enorme lacuna que existe em relação aos estudos sobre ectoparasitas aviários e destacam potenciais vetores de hemoparasitos para as espécies de aves estudadas.
