Recently, there’s been one mastitis pathogen that’s been bugging farmers more than normal. Frustrated by higher than normal clinical case rates and/or bulk milk cell counts, in-house cultures have found Strep dysgalactiae to be one of the pathogens involved (we’ll call it Strep dys as it's much easier to say!) Where does Strep dys come
Have you ever wondered how many heifers have blind quarters or mastitis 1 to 2 months before calving? Well wonder no more! We've tipped and teatsealed a lot of heifers over the years. Sometimes we’ll diagnose heifers with mastitis: swelling and hardness of the gland and a thick, custard-like secretion. While in-house cultures of these
Zoe Vogels It's always nice to see a good news story, and this week's one comes from the Australian War Memorial in Canberra. A pigeon was caught stealing poppies from the Tomb of the Unknown Soldier, using them to make a beautiful red nest. Given it's the 11th of November, how about a departure from
Have you, or your friends or family, ever thought about being a vet? Read on as Dr Izzy Moorhead answers the where, why and how of getting into Vet School. Where can you study vet in Australia?

Pink eye pain... Pink eye - or corneal ulceration - causes farmers and stock a lot of grief! While it usually occurs in young stock from November through to March, it's increasingly being seen over the winter months too. Pink eye is mainly caused by the bacteria Moraxella bovis and Moraxella bovoculi, both of which
Dr Sarah Matthews Have you ever had a heifer with a spontaneously broken leg? Or young stock that have light, scruffy coats and struggle to put on weight? If you have, then you are not alone. Copper and selenium are two of the key trace elements required by cattle for growth, production and good health.
A short, 22 second video of bacteria multiplying was doing the rounds of the internet last week. But why did it have so many scientists excited? First, a bit of an explanation about how bacteria grow and multiply… What do bacteria look like? Bacteria are single cell organisms and can be round, rod-shaped or wavy.
Lungworm, caused by the round worm Dictyocaulus viviparus, generally occurs in heifers less than 10 months of age. In particular, those heifers with no immunity that are exposed to high numbers of worm larvae when put onto pasture (such as a group of Spring-born calves weaned onto pasture grazed by Autumn calves). Lungworm disease can
Last week was #InternationalMicroorganismDay, so we thought we'd shine the light on some of the microbes that can be the most frustrating: those that cause calf scours! The microbes that cause calf scours (aka calf diarrhoea) can be viruses, bacteria and/or protozoa that damage the lining of the gut. This means that the milk and
Toxicities that cause disease and death of calves are luckily few and far between. When they do occur – sometimes from a simple mistake - it is extremely upsetting for those involved. But if we can use the bad as a timely reminder, we can help ensure it doesn't happen to anyone else. Recently
