ectoparasites

2

Lately I have been the mite whisperer!  I had four cases of Demodex last week and two cases of Sarcoptes!  Sarcoptic mange, caused by the little creature in the first photo, is transmissable to humans and other animals.  It causes a self-limiting infection in people with itching and redness, but in dogs, the infestation can be severe and excruciating.  Demodectic mange is not uncommon in puppies, who are still developing their immune system; Demodex, unlike Sarcoptes, is a normal inhabitant of most mammals, including people.  Demodex mites only become a problem when the immune system is suppressed; if that’s the case, they can infest the whole body and also cause pain and itchiness.  Both types of mange leave the pets open to secondary bacterial invasion.

Sarcoptes can be fairly easily treated with Revolution topically.  Demodex, however, is a huge pain in the butt to treat and requires time-consuming and dangerous dips, or oral ivermectin, which can cause nasty side effects.  I hate Demodex!

I love every blog I follow, they are fabulous & have given me so much inspiration in my short time here, therefore as of tonight I will be taking my blog on a personal adventure. I want to utilize the knowledge I am gaining as a student veterinary nurse, for other users to enjoy, share if they wish to & for my own benefit of revision.

My main aim is to write blog posts about subjects I have covered, which hopefully will turn out to be a ‘not so boring’ way of revising in preparation for my end of the year exams. 

There is no rest for the wicked at veterinary nursing school! Revision must begin.

Ectoparasites

I’ve spent 45 minutes of today in the lab looking at these little creatures & let me tell you… it is not easy to take a good photo with your phone no matter how hard you try!

Top Left: Ctenocephalides canis i.e. Dog flea

(The slide was not marked, I believe it is a dog flea due to the shorter size of it’s head) 

Physical characteristics:

  • 1-6 mm in length
  • wingless
  • laterally flattened
  • light brown in colour
  • body is divided into head, thorax & body

Few Facts:

  • Females produce 30-50 eggs daily
  • Feed on hosts blood
  • Life span of 50-100 days
  • 3 larval stages 
  • Total development cycle takes 3-5 weeks
  • Fleas are not host specific 
  • Faculatative parasite- may live & feed on host occasionally but not completely dependent

Top Right: Linognathus stetosus i.e. Sucking lice

General Lice Characteristics:

  • Wingless
  • 0.5 to 8 mm in size
  • Dorsoventrally flattened
  • Stout legs and claws
  • Feed on  epidermal tissue debris, blood, secretions
  • Chewing lice-head larger in relation to body
  • Sucking lice- head smaller in relation to body
  • Highly host specific 
  • Females produce 1-2 eggs daily
  • Life span of 1 month

Linognathus stetosus:

  • Strong legs
  • Claws on each leg
  • Long narrow head
  • Undergoes 3 nymphal stages 

Okay so here we go… Short little start to the theme. Hope its alright, any feedback would be largely appreciated!!

u got a problem with lizard boobs??!!

Like you could be joking but every time I see it on a half-dragon, Kobold, or whatever reptilian fantasy race I get a little twinge in the back of my mind that screams, “THAT AIN’T RIGHT”.

I know in 90% of instances its just a furry artist slapping what people find sexy onto the body of an anthropomorphic animal but for those who are making an OC, going the extra mile is pretty cool and shows your character isn’t just a sexual object. A quick google search reveals what reptiles look for in a mate. It absolutely varies from species to species but here’s an example I found off Wikipedia, “In striped plateau lizards (Sceloporus virgatus), females develop an orange color on their throat area signaling that they are ready to mate (only during the breeding season). A brighter orange color represents a higher quality female (fewer ectoparasites, and larger egg mass)“ So you could make your tit-less Dragonborn have orange coloration on her neck. All the other Dragonborn be like, “oh fuck!!!!!!!!!! look at the neck on that shorty!!” while the humans and dwarves in your party just see a discoloration on her gross leathery neck

This applies to other animal races as well. IE Gnolls, Salamanders, Aarakocra and HELLA more.

In short, quit being a furry piece of shit and take an actual interest in a species’ physiology.

Thank you for watching “Adventures in…and Saving the World”.

 Here is the research I used to inspire my performance. I hope it inspires you as it did me. If you have any questions or comments, please visit Conservation Theater Trends on Facebook or Tumblr. Thank you.-Bricken Sparacino

Wilderness Survival: Preventative Measures and Off Grid Treatment for Deadly Bugs

Hi there, guys and gals reading Ready Nutrition today! I believe Ready Nutrition’s Joshua Krause and I must have had a subconscious “Vulcan Mind Meld.” He just wrote a great article on Tick Removal and Prevention, and here I am with this piece on diseases from these egregious ectoparasites. The advice he gave is really important concerning these creatures, as an ounce of prevention is worth a pound of cure. If your tick makes it through the defenses Josh outlined, well, here’s some information concerning the diseases they carry and some facts to arm you in your battle. The Usual Suspects As the weather warms up and people begin to venture outdoors once more, they will be more susceptible to being bitten. http://b4in.com/fMwX

When you think of animals, think of this bug, Cimex adjunctus. Bat bugs are ectoparasites of bats, but will bite humans if bats are not available. They are closely related to bed bugs, and most infestations of “bedbugs” in the U.S. are actually bat bugs, though true bedbugs are becoming more common. The biggest difference in appearance is the fringe hairs in on the “shoulders” (pronotum) are much longer in the bat bug.
