| avian malaria seroprevalence in jackass penguins (spheniscus demersus) in south africa. | blood samples of 191 adult jackass penguins (spheniscus demersus) from south africa were tested by indirect enzyme-linked immunosorbent assays (elisa) with plasmodium falciparum antigen (r32tet32) for avian malaria antibodies (ab). the samples originated from free-ranging penguins from offshore islands and southern coast colonies (3 groups, n = 110), from 2 penguin groups (n = 66) rescued after offshore oil-spill contamination and rehabilitated at the rescue station of the south african national ... | 1995 | 7472859 |
| plasmodium juxtanucleare associated with mortality in black-footed penguins (spheniscus demersus) admitted to a rehabilitation center. | five black-footed penguins (spheniscus demersus) admitted to the southern african foundation for the conservation of coastal birds, in cape town, south africa, died from malaria infection. evidence for malaria as the cause of death included antemortem clinical signs, parasitemia, splenomegaly, pulmonary edema, and the presence of histologically visible schizonts in the reticuloendothelial system. a portion of the malarial small subunit ribosomal ribonucleic acid gene was detected by polymerase c ... | 2003 | 14582786 |
| Novel relapsing fever Borrelia detected in African penguins (Spheniscus demersus) admitted to two rehabilitation centers in South Africa. | The African penguin, Spheniscus demersus, the only penguin species that breeds in Africa, is endangered, and several diseases including avian malaria, babesiosis, and aspergillosis are common in some populations. From 2002 to 2010, spirochetes morphologically consistent with Borrelia were observed on thin blood smears from 115 of 8,343 (1.4%) African penguins admitted to rehabilitation centers in the Western Cape and Eastern Cape provinces of South Africa. Prevalence rates were significantly hig ... | 2011 | 21870246 |
| establishment of baseline haematology and biochemistry parameters in wild adult african penguins (spheniscus demersus). | there are few publications on the clinical haematology and biochemistry of african penguins (spheniscus demersus) and these are based on captive populations. baseline haematology and serum biochemistry parameters were analysed from 108 blood samples from wild, adult african penguins. samples were collected from the breeding range of the african penguin in south africa and the results were compared between breeding region and sex. the haematological parameters that were measured were: haematocrit ... | 2015 | 26016391 |
| hand-rearing, release and survival of african penguin chicks abandoned before independence by moulting parents. | the african penguin spheniscus demersus has an 'endangered' conservation status and a decreasing population. following abandonment, 841 african penguin chicks in 2006 and 481 in 2007 were admitted to sanccob (southern african foundation for the conservation of coastal birds) for hand-rearing from colonies in the western cape, south africa, after large numbers of breeding adults commenced moult with chicks still in the nest. of those admitted, 91% and 73% respectively were released into the wild. ... | 2014 | 25337698 |
