WormFaxNSW – April 2017 edition

The April edition is now up on the web:

Due to mild to warm temperatures and above average rain in autumn in many areas in NSW, high worm egg counts were not unusual, and often due to barber’s pole worm.

See also Andrew Biddle’s comments reported in the article, ‘Northern sheep losses’.

Better than just looking at numbers (WormFax), read ParaBoss News, where there is commentary by experts in various regions in Australia on sheep worms and other health issues.

In NSW, most of this commentary comes from the LLS District Veterinarians. Your rates and taxes at work! 

ParaBoss news helps to make ParaBoss, including WormBoss, Australia’s premier resource on parasite management in sheep (worms, flies, lice) and goats (worms only). (And ‘cattle’ are in the pipeline….)

Northern sheep losses

A great resource. (In my humble but authoritative opinion 🙂 )

Wild Dogs in Australia

Published on May 16, 2017

In this video, Dr Ben Allen and Dr Matt Gentle from Queensland give an overview as to the current impact of wild dogs in Australia and what we know about their ecology, movement and behaviour.

This video was funded through the National Wild Dog Action Plan.

Noogoora burr project aims to develop bio-herbicide

A NEW project focused on developing a bio-herbicide to tackle Noogoora burr, a weed which impacts on both cropping and livestock industries in the eastern states of Australia, has received Federal Government funding.

Broad Spectrum Anthelmintic Resistance of Haemonchus contortus in Northern NSW – case report

Lamb J and others, 2017. Broad Spectrum Anthelmintic Resistance of Haemonchus contortus in Northern NSW of Australia. (Short communication). Vet Parasitology. https://doi.org/10.1016/j.vetpar.2017.05.008

Highlights

  • Faecal egg count reduction test conducted in Northern NSW highlighting resistance.
  • Haemonchus contortus demonstrated resistance to a broad spectrum of anthelmintics.
  • Reduced efficacy to anthelmintics in combination and recently registered products.
  • Anthelmintics used as fundamental control of internal parasites.

Abstract
On a sheep farm in Northern New South Wales (NSW) of Australia a degree of anthelmintic resistance was suspected. With noticeable clinical signs of infection and sheep not responding to treatment, a faecal egg count reduction test was conducted to ascertain the broad spectrum of anthelmintic resistance at this farm. A number of classes of anthelmintics were assessed including organophosphate, macrocyclic lactone (ML) and in combination an ML, benzimidazole, levamisole and salicylanilide. In addition, the more recently registered classes of anthelmintics, monepantel (amino-acetonitrile derivative) and derquantel/abamectin combination (spiroindole + ML) were included.

Ninety merino sheep naturally infected with a field strain of Haemonchus contortus were randomly allocated to 6 treatment groups (15 animals/group). Sheep were subsequently treated based on label recommendations and individual bodyweight. Faecal samples were collected post-treatment on Days 7, 14 and 21 to conduct faecal egg counts and group bulk larval cultures.

Broad spectrum anthelmintic resistance was confirmed at this site with treatment efficacies ranging from 21.3% (monepantel) to 93.8% (derquantel/abamectin combination) against the H. contortus strain. Furthermore, resistance to the multi-combination anthelmintic containing 4 active ingredients was evident (52.5%). This broad spectrum of resistance highlights the need for integration of alternative sustainable methods in parasite control in order to slow development of resistance and increase the life time effectiveness of anthelmintics.

Price of drenches

If you subscribe to ParaBoss Monthly News, you would already know this…

BUT…ParaBoss Operations manager Dr Deb Maxwell says this in the latest feature article..

The WormBoss Drenches section now shows drench prices—but price per dose should be at the bottom of the list of criteria when choosing a drench. >> Read more.

Bottom line: the most expensive drench is the one that doesn’t work

Using composite fecal samples when testing for anthelmintic resistance in gastrointestinal nematodes of cattle

George MM, Paras KL, Howell SB and Kaplan RM, 2017. Utilization of composite fecal samples for detection of anthelmintic resistance in gastrointestinal nematodes of cattle Veterinary Parasitology 240 15 June 2017 pp24–29

Highlights
98.9% agreement in mean fecal egg count of individual and composite samples.
95.9% agreement in fecal egg count reduction of individual and composite samples.
Methods for conducting composite sampling were described.
Composite sampling is a practical tool for cattle producers to assess resistance.
This method may improve parasitological testing among producers.

Metformin: its botanical background
Dr CJ Bailey PhD, FRCP, FRCPath, C Day PhD, PGCE, CBiol

http://onlinelibrary.wiley.com/doi/10.1002/pdi.606/full

Abstract

This article traces the roots of the antihyperglycaemic biguanide metformin from the use of Galega officinalis (goat’s rue or French lilac) as a herbal treatment for the symptoms of diabetes. G. officinalis was found to be rich in guanidine, a substance with blood glucose-lowering activity that formed the chemical basis of metformin. This insulin sensitising drug was introduced in 1957.

Postscript of ironies

There are several ironies about metformin. In our high-tech era of drug discovery and development this first-line treatment for type 2 diabetes is little removed from a herbal remedy of the middle ages. Despite its chemical simplicity and detailed investigation, metformin continues to evade a complete exposé of its cellular activity. While endless pharmacovigilance has monitored the safety profile of metformin, its natural ancestor, G. officinalis (known as Professor Weed in the USA) is a Class A Federal Noxious Weed in 35 states of America, and appears on the database of poisonous plants.32, 33 It is perhaps apt to conclude with a quote from the Swiss born physician Theopharastus Bombastus von Hohenhein (1493–1541), better known as Paracelsus: ‘The right dose differentiates a poison from a useful medicine’.
