Absence of transmission of potentially xenotic viruses in a prospective pig to primate islet xenotransplantation study.

Shortage of human donor organs for transplantation has prompted usage of animals as an alternative donor source. Pigs are the most acceptable candidate animals but issues of xenozoonoses remain. Despite careful monitoring of designated pathogen free pigs there is still a risk that their tissues may carry infectious agents.

Identification of five major and two minor genotypes of varicella-zoster virus strains: a practical two-amplicon approach used to genotype clinical isolates in Australia and New Zealand.

Whole genome phylogenetic analysis in this study resolved a total of five major genotypes among the 22 varicella-zoster virus (VZV) strains or isolates for which complete genomic sequences are available. Consistent with earlier publications we have designated these genotypes European 1 (E1), European 2 (E2), Japanese (J), mosaic 1 (M1), and mosaic 2 (M2). Single nucleotide polymorphism (SNP) analysis performed in a whole-genome alignment revealed that VZV isolates of all five genotypes can be accurately genotyped using SNPs from two amplicons: open reading frame 22 (ORF22) and either ORF21 or ORF50.

Hepatitis E in new zealand.

Background And Aim: Locally acquired hepatitis E virus (HEV) infection has been described in a number of developed countries and is thought to be zoonotic from pigs. Little is known about hepatitis E in humans in New Zealand (NZ) but 90% of NZ pigs show evidence of HEV infection. The aim of this study was to investigate the epidemiology of hepatitis E infection in NZ by documenting HEV immunoglobulin (Ig) G seroprevalence in NZ blood donors, testing patients with unexplained hepatitis for HEV, and comparing genetic sequences of human HEV with local porcine isolates.

Sirolimus for Kaposi's sarcoma.

The risk of Kaposi's sarcoma (KS) is increased after organ transplantation. Management of KS in the cardiac transplant population may be difficult because reduction of immunosuppression is often not practical. This report describes a case of KS occurring in the early post-transplant period.

Monitoring for potentially xenozoonotic viruses in New Zealand pigs.

Shortage of human donor organs for transplantation has prompted evaluation of animals as an alternative donor source. Pigs are the most acceptable candidate animals but issues of xenozoonozes remain. Despite careful monitoring of high-health-status (HHS) pigs, there is still a risk that their tissues may carry infectious agents.

An echovirus type 33 winter outbreak in New Zealand.

Echovirus type 33 (E33) is a relatively uncommon enterovirus. An E33 outbreak during the winter of 2000 in New Zealand led to 75 virologically-confirmed cases of E33 infection (2.6 cases per 100,000 individuals).
