Esophageal Foreign Body!
Here is a little Memorial Day weekend treat for you all! The entire alphabet…in the form of neutrophils! Enjoy scrapbooking with them!
I absolutely wish I could take credit for this…but this little piece of genius was cooked up by Adam Morgan and David Yang. This was published in the journal Blood (Blood. 2013. 121:3546). The original link is: http://bloodjournal.hematologylibrary.org/content/121/18/3546.full.
I present to you Ctenocephaildes felis (pronounced ten-oh-kef-ali-dees), also known as the common flea. Some of you that have a bit of latin common sense may note that the felis may relate to cats, however this is also the most common flea in dogs.
HOW DO YOU KNOW? I hear you cry.
Well the second photo highlights the main differential points of the fleas used to identify. circled in red are the ‘combs’ or ‘ctenidia’. These are chitinous spines. They appear in either none, one (pronotal - the ones at the left of the photo, posterior comb for the slightly more technical term) or both (pronotal and genal - the ventral aspect or moustache as some might say).
Fleas with no combs present belong to the genus Pulex (the only species of importance is P. iritans also known as the human flea which is thankfully rare in the UK). Fleas with the pronotal comb belong to the genus Ceratophyllus (The flea that infects poultry belongs to this genus C. gallinae). The genus with both combs as seen above is Ctenocephalides. This genus has in it C.felis and C. canis. Although there is a dog specific flea the felis is the more common one.
C. felis is differentiated from C. canis by the shape of the head. In C. felis the head shape is much smoother and less curved (shown wonderfully by that blue line. C. canis has a much rounder, almost angular head.
In the US our “cephalo-” words are pronounced “sephalo-” instead of “kephalo-.” It really threw me for a loop when I was over in England studying and my fellow student brought up “enKEPHalitis” as a differential! Also we say “TRAY-key-a” for trachea, but in England I heard “Trah-KEY-a.” This post just reminded me of that :)

A dog named Pay de Limon (Lemon Pay) runs, fitted with two front prosthetic legs at Milagros Caninos rescue shelter in Mexico City, on August 29, 2012. Members of a drug gang in the Mexican state of Zacatecas chopped off Limon’s paws to practice cutting fingers off kidnapped people, according to Milagros Caninos founder Patricia Ruiz. Fresnillo residents found Limon in a dumpster bleeding and legless. After administering first aid procedures, they managed to take him to Milagros Caninos, an association that rehabilitates dogs that have suffered extreme abuse. The prosthetic limbs were made at OrthoPets in Denver, Colorado, after the shelter was able to raise over $6,000. (Reuters/Tomas Bravo)
I finally got a picture of the Torogoz which is the National bird of El Salvador.
