Cats, as well as dogs with erect ears that have control over ear direction, may be seen with one or both ear pinnas held at an odd or flattened angle. The most common lesion associated with ear mites is an open or crusted ("scabbed") skin wound at the back or base of the ear, caused by abrasion of the skin by hind limb claws, as the ear has ...

Ear infections often result in a darker red ear, dirt in the ear, or a general inflamed appearance. Chronic allergic otitis externa in a dog with atopic ...
Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
Although kennel cough is considered to be a multifactorial infection, there are two main forms. The first is more mild and is caused by B. bronchiseptica and canine parainfluenza infections, without complications from canine distemper virus (CDV) or canine mastadenovirus A (formerly canine adenovirus-1).

A metaphase cell positive for the BCR/ABL rearrangement using FISH.

The Terminologia Histologica (TH) is the controlled vocabulary for use in cytology and histology. [1] [2] In April 2011, Terminologia Histologica was published online [3] by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT.

Canine histiocytoma cytology. A histiocytoma originates from epidermal Langerhans cells of antigen-presenting cell lineage. [4] Spontaneous regression is common in these tumors, and it is mediated by infiltration of CD8-expressing T cells followed by expression of Type 1 T helper cell cytokines (such as Interferon-gamma) and recruitment of antitumour effector cells.
