Investigation of a mortality cluster in wild adult yellow-eyed penguins (Megadyptes antipodes) at Otago Peninsula, New Zealand. Avian Pathol. 2016 Dec 06;:1-26 Authors: Gartrell B, Agnew D, Alley M, Carpenter T, Ha HJ, Howe L, Hunter S, McInnes K, Munday R, Wendi R, Melanie Y Abstract We investigated an epidemic mortality cluster of yellow-eyed penguins (Megadyptes antipodes) that involved 67 moribund or dead birds found on various beaches of the Otago Peninsula, New Zealand, between January 21 and March 20, 2013. Twenty-four carcases were examined postmortem. Histological lesions of pulmonary, hepatic and splenic erythrophagocytosis and haemosiderosis were found in 23 of 24 birds. Fifteen birds also had haemoglobin-like protein droplets within renal tubular epithelial cells. Despite consistent histological lesions, a cause of death could not be established. Virology, bacteriology and molecular tests for avian influenza, avian paramyxovirus-1, avipoxvirus, Chlamydia psittaci, Plasmodium spp, Babesia spp, Leucocytozoon spp, and Toxoplasma gondii were negative. Tissue concentrations of a range of heavy metals (n = 4 birds) were consistent with low level exposure, while examination of proventricular contents and mucus failed to detect any marine biotoxins or Clostridium botulinum toxin. Hepatic concentrations of total polycyclic aromatic hydrocarbons (PAHs) (n = 5 birds) were similar to background concentrations of PAHs previously found in yellow-eyed pengu...
[The Conversation Africa] The infectious disease burden in Africa is very high, particularly for tuberculosis (TB), malaria and HIV/AIDS. In 2018, nearly a quarter (24%) of TB cases in the world were in Africa. The region accounted for 93% of malaria cases. The continent also bears the brunt of the HIV epidemic: 20.6 million of the 37.9 million people living with HIV are in eastern and southern Africa.
The country ’s need highlights a little-known type of organ donation.
ConclusionAlthough the literature suggests splenic involvement is a rare finding, acute parasitemia with babesiosis commonly affects the spleen. Recognition of this association can aid radiologists diagnosing splenic involvement in babesiosis and can lead to appropriate intervention in the minority with splenic hemorrhage.

Glenn and colleagues have examined rates of adolescent suicide across 45 countries and explored the role of sex, age, rurality and availability of guns and railways on suicide rates. Higher rates of adolescent suicide in New Zealand may be explained by the...
One of Dayton ’s largest nonprofits is at the forefront of efforts to aid victims of a volcanic eruption overseas. Community Tissue Services, based in Kettering, has shipped nearly 1,000 skin grafts to New Zealand to treat victims of the recent White Island volcanic eruption. New Zealand has requested 1,292 s quare feet of skin to treat patients who were injured in the eruption. Christopher Graham, chief business development officer at Community Tissue Services, said the organization has provided…
