“…In the pre- sent study, many specimens of C. plaumanni were captured using both the CDC traps and live bait, and they are most likely the main agents responsible for the emergence of the disease. The occurrence of this insect has been reported in Brazil (in the state of Amazonas), Argentina, Peru (Felippe--Bauer et al 2008), Bolivia, and Colombia (Spinelli et al 2009). However, there are no case reports of allergic dermatitis in domestic animals associated with this species, although a few insects have previously been collected close to sheep and poultry in Peru (Felippe-Bauer -unpublished data).…”

Clinical and epidemiological data were obtained during monthly visits to the farm. Skin biopsies were performed for histopathological examinations, and insects were captured with Centers for Disease Control and Prevention (CDC) traps and live-bait entomological vacuum devices. The property housed a herd of both genders, with 45 Santa Inês sheep of different ages and 72 Texel adults. Of the 72 Texel sheep, 56 were affected. Of these, 24 exhibited alopecia, erythema, edema, and crust in the ears, on top of the head, and less often, around the eyes. In addition to the lesions described above, 14 animals exhibited hyperpigmentation of the ears and/or around the eyes and crust in the nose. Another 18 animals exhibited chronic lesions characterized by deformed and thickened ears, alopecia with hyperpigmentation, and in most cases, secondary bacterial infections with abscesses and/or myiasis. Some of these animals had lost part of their ears. Histologically, the lesions were characterized as orthokeratotic hyperkeratosis, acanthosis, vacuolization, and necrosis of epidermal cells. An inflammatory infiltrate was present in the dermis, which was composed mainly of eosinophils and macrophages, some lymphocytes and mast cells, and few neutrophils, in addition to edema and collagen deposition. The Santa Inês sheep were not affected. Among the captured insects, 294 specimens of Culicoides (Hoffmania) plaumanni Spinelli, 57 specimens of C. (Hoffmania) insignis Lutz, and 27 specimens of other Culicoides species were identified. We conclude that C. plaumanni, C. insignis, and possibly other Culicoides species are involved in the etiology of allergic dermatitis in Texel sheep in the state of Pará. Santa Inês sheep in the same region and under the same conditions were not affected, which suggests lower susceptibility of these animals.

“…In the north-west of Argentina, Veggiani Aybar et al (2013) described C. paraensis Goeldi and C. lahillei Iches as the most frequent Culicoides species. Other reports also point C. insignis and C. pusillus as the main representatives of the genus Culicoides in all South America (Felippe-Bauer et al, 2008;Gibbs et al, 1983;Gouveia et al, 2003;Greiner et al, 1992;Homan et al, 1990;Legisa et al, 2013). BTV has been isolated from C. insignis and C. pusillus both in Central America and the Caribbean but not in South America.…”

Blood parasites of penguins: a critical review

2016

View full text Add to dashboard Cite

Blood parasites are considered some of the most significant pathogens for the conservation of penguins, due to the considerable morbidity and mortality they have been shown to produce in captive and wild populations of these birds. Parasites known to occur in the blood of penguins include haemosporidian protozoans (Plasmodium, Leucocytozoon, Haemoproteus), piroplamid protozoans (Babesia), kinetoplastid protozoans (Trypanosoma), spirochete bacteria (Borrelia) and nematode microfilariae. This review provides a critical and comprehensive assessment of the current knowledge on these parasites, providing an overview of their biology, host and geographic distribution, epidemiology, pathology and implications for public health and conservation.
