Lepto Webinar 2017

Free webinar on the recent leptospirosis study

The Farmer Leptospirosis Action Group (FLAG - Dairy) will be hosting a free webinar to inform veterinarians on the findings of the recent leptospirosis study. The study explored the effect of long-term vaccination in a nationally representative sample of herds.

Lepto Forum 2017

LEPTOSPIROSIS: An Occupational Disease.

Massey University Leptospirosis Research Group Forum 2017 : discuss recent research into leptospirosis and its control in the occupational exposed workers

The Group presents recent studies that investigated leptospirosis in pastoral livestock and humans including people who have been exposed to Leptospira at the workplace i.e. meat workers, farmers and veterinarians. We would like to discuss the findings with your sector to help facilitate the development of measures for preventing leptospirosis in such occupations.

Marie Moinet

IDReC Marie Moinet  : Leptospirosis: should we shift the focus to wildlife?

There has been a recent increase in human notifications and change in the serovars, of leptospirosis cases, reported in Northland. From Jan 1 to 30 July 2016 there were 13 notified cases of leptospirosis (10 confirmed and 3 suspect) compared with the average over the last 9 years (2007 to 2015) of 4 per year. Of the 10 confirmed cases, 8 were wildlife associated serovars.

Although wildlife (especially rodents) have been pinpointed as a probable source of infection, its role remains poorly defined and has not been thoroughly investigated in New Zealand for more than 30 years.

A pilot study carried out in 2014/2015 on a small sample of brush-tailed possums, feral cats, mustelids, rodents and hedgehogs confirmed that exposure, colonisation and shedding were present. The rising importance of serovar Ballum in humans, a serovar associated with rodents and hedgehogs, and issues around cattle vaccine efficacy raised further critical questions about the role of wildlife.

Dr Anou Dreyfus  : PLOS Neglected Tropical Diseases Research Article on Leptospira Seroprevalence and Risk Factors in Health Centre Patients in Hoima District, Western Uganda

Dr Anou Dreyfus a Senior lecturer and researcher at University of Zurich, Section of Epidemiology (Previously with EpiCentre , Massey University). Published a paper on Leptospira Seroprevalence and Risk Factors in Health Centre Patients in Hoima District, Western Uganda. 

The burden of human leptospirosis in Uganda is unknown. We estimated the seroprevalence of Leptospira antibodies, probable acute/recent leptospirosis, and risk factors for seropositivity in humans in rural Western Uganda.

FLAG - Dairy Survey 

By the end of February 2016, 96 veterinary practices throughout New Zealand had collected samples from 168/200 dairy farms. DNA was extracted for qPCR from the urine of 3,360 cows and blood sera plated for over 15,000 MAT tests. The project is on target for generating results until end of 2016.

NZVA urges farmers to vaccinate stock against leptospirosis at an early age.

Leptospirosis is a significant risk to New Zealand farmers and the New Zealand Veterinary Association (NZVA) continues to reinforce the message for farmers to vaccinate young stock against leptospirosis at an early age and to maintain protection through animal boosters. Dr Jenny Weston, President of the NZVA’s Society of Dairy Cattle Veterinarians says Leptospirosis is a highly infectious disease that can crossover from animals to humans.

Disease warning : Leptospirosis could affect dairy growth

The effect of leptospirosis on production is being researched at Massey University.

The results of deer studies show a correlation between vaccination and growth rates and weaning percentages; data from a sheep and beef cattle study is being analysed and a funding application is underway to do more research into the effects on dairy cows, says Professor Peter Wilson.

Leptospirosis video potential lifesaver for farmers.

A new video series produced and developed by Massey University researchers may save some of the 100 people each year that are affected by leptospirosis. 

The seven-part series aims to give farmers information to protect themselves, their families, workers and livestock from the bacterial disease that hospitalises more than 50 people each year

IDReC Researchers invited to attend international leptospirosis meeting.

Researchers Dr Jackie Benschop and Professor Peter Wilson have been invited to attend the 4th Global Leptospirosis Environmental Action Network (GLEAN) Technical Meeting in Sri Lanka later this month.

The purpose of the GLEAN annual meeting, which runs from 18-20 November, is to bring together national and international experts that have been working on surveillance, diagnosis, case management, prevention and control of leptospirosis. The meeting will focus on developing recommendations for leptospirosis prevention and control, including outbreak response.
