Abstract

<i>Salmonella</i>Typhimurium in Hihi, New Zealand

Highlights

  • To the Editor: The recent finding of a previously unrecorded Salmonella strain in an endangered New Zealand passerine offers the rare opportunity to observe the initial arrival and pathology of an epizootic and to determine its population-level effect

  • Typhimurium DT195 outbreak occurred within a reintroduced population on Tiritiri Matangi Island

  • Screening in all hihi populations during 2004 found no evidence of Salmonella infection (32 adults and juveniles at Tiritiri Matangi, 29 at Hauturu, and 27 at Kapiti), and a 15-year pathology database from 230 dead hihi collected across these populations and a captive breeding facility lists no salmonellosis cases

Summary

Introduction

To the Editor: The recent finding of a previously unrecorded Salmonella strain in an endangered New Zealand passerine (the hihi, Notiomystis cincta; [1]) offers the rare opportunity to observe the initial arrival and pathology of an epizootic and to determine its population-level effect. Hihi are nectar-feeders that declined to near extinction after European colonization of New Zealand and survived on a single island refuge (Hauturu). Typhimurium DT195 outbreak occurred within a reintroduced population on Tiritiri Matangi Island.
