An article recently published in Environmental Science and Technology details a study conducted at Johns Hopkins where when examining samples of commercially available feather meal (used as a protein supplement feed or fertilizer) they found trace amounts of fluoroquinolones, a class of antibiotics that have been banned for use in animal feed for 6 years. This is an interesting find, and definitely warrants further research before any broad sweeping conclusions can be made. You know...unless you........ Read more »

The first of a bunch of articles I recently picked out of JAVMA was interesting because while I never got any readings without some form of anesthesia, I imagine that hypertension was extremely common in many of the dogs I saw at Lapaw Animal Hospital. Whether it’s a result of obesity, illness, or hospital stress, systemic hypertension is usually an indicator of some other problem, and therefore important in the analysis of the patient......

Following my recent post where I examined an article from Johns Hopkins that found multiple contaminants in commercial feather meal (including fluoroquinolones, a class of antibiotics that have been banned from use in poultry since 2005), I was honored to be contacted by one of the Authors, Dr. David Love. Dr. Love offered to continue the discussion with me, and was happy to answer my questions regarding the study, the media frenzy it has inspired, and some of the goals of the research conducted........

Generally not small talk, though I imagine they might be interested in the projections for this year's salmon run (pause for polite awkward laughter). A new article from PLoS ONE has been discussed, implying that, while direct contact may not be routine, exchange of disease between domesticated and wild cats may be fairly common.... Read more »

Badger culling has been a part of TB control in the United Kingdom since 1973. Despite this and other programs in place, incidence of TB has only increased during that time. In the thousands of biological and environmental risk factors that have been associated with TB infection risk, Badgers have been identified as an important reservoir and potential vectors for the disease......

N-terminal portion of pro C-type natriuretic peptide. Try to say that one three times fast. ScienceDaily has a cool article detailing a couple new studies showing that this peptide (Nt-pCNP) could be a solid indicator of sepsis as opposed to a generalized inflammatory response. It could potentially be added to current serum chemistry analysis, or packaged as an ELISA snap for quick, in-house diagnostics for pertinent cases...... Read more »

Just a short one here today. Not too much interesting going on in a study that supports the null, but the methods are great.
This study looked at the affect that one or two rectal palpations to determine pregnancy had on embryo viability. I can see why there would be a question, it seems like a highly invasive procedure when you're shoulder deep in cow rectum and feeling for an amnion several layers of membranes away. But we tend to anthropomorphize, and many dairy cattle require minimal r........ Read more »

I recently had a professor tell me that if I didn’t let them know if I made it into vet school, they would forever curse me with fat, in heat, Labrador spays for the rest of my career. I can think of few fates worse for a future veterinarian (though I did mention that the owners also had to have no way to pay, and will forget to mention this until after the procedure). Today’s article is really cool and discusses the prevalence of ovariohysterectomy and orchiectomy (spaying and neutering, f........ Read more »

” A viral emergence is generally defined as the appearance of a new pathogen for a host, such as human immunodeficiency virus (HIV)-1 for humans in the twentieth century. Viral re-emergence often refers to the reappearance of a viral pathogen after a period of absence, such as the periodic human influenza epidemics or pandemics.” (Domingo, 2010)
There’s a huge amount of information on viral evolution and mutation, a concept that (like everything else you haven’t specif........ Read more »
Ah, United States' medicine vs. European medicine, the war rages on. The battleground I'll discuss today: elective sterilization of the female reproductive tract.
This discussion came up in JAVMA recently, and I felt it warranted a look from a future vet. Granted I don't have all the information and education here, but given that I've only ever seen ovariohysterectomy performed in practice, I'm interested in why we actually choose to remove the uterus as well......

Cats and urinary problems go paw in paw, from the obstruction emergency in males, to common urolithiasis. As a cat owner, it is always important to search for a medical problem before blaming behavioral issues for “accidents” in the house. There’s a whole world of disease out there that can manifest itself as litter box trouble. This article in JAVMA discusses the protein analysis of both healthy cats and those with idiopathic cystitis, urolithiasis, or a UTI...... Read more »

We've known for a long time that owning pets is good for us. They encourage exercise (Epping, 2011), lower blood pressure (Allen Et Al., 2002), and even reduce anxiety (Jerjes, 2007). So the question then is why wouldn't we want to bring that to work?
This article looked at just that. In examining a large company with about 550 employees, and comparing their results to the standards of the industry, the authors found that the presence of a dog at work reduced stress for employees thro........ Read more »

I’m apparently still on this immunology kick, because I seem to be finding it everywhere. Heck, I recently learned that we’ve cured the allergic response to peanuts and eggs in lab mice. Check out the link, the author is hilarious and the material is interesting.

Few agricultural debates come close to generating the same passionate and heated responses that organic farming seems to elicit. The discussion surpasses the interests of producers with conflicting ideologies to be hotly debated by assertive consumers as well; people who highlight the paradox created by their interest in the safe and responsible production of their food, while avoiding all involvement in its creation. The originally proposed Organic Foods Production Act of 1990 received nearly 3........ Read more »

...Her masters thesis explores the background for my intended study, in that it seeks to examine not only those factors inherent to the cats and their housing situation, but in what potential adopters are looking for. I’m hoping to collect as much of this information as possible to develop a hypothesis as to whether shelter layout could increase adoption rates by marketing less attractive cats in situations where they may be perceived as more adoptable......
