Cutaneous mucinosis in a strain of brown-egg laying chickens.

Cutaneous mucinosis is a cutaneous disorder described in humans, dogs, and rarely cats but never reported in birds. Twenty-six brown egg-laying chickens between ages 43 and 46 weeks had a history of feather loss, scaly, dry skin, weight loss, and decreased egg production. Microscopic findings in the skin included fragmentation of collagen bundles and interstitial, periadnexal, and perivascular dermal accumulation of wispy, mildly basophilic material that was also occasionally observed within the follicular epithelium.

Parasitic ventriculitis caused by Hadjelia truncata in California rock pigeons (Columba livia).

Severe ventriculitis and emaciation caused by the infestation of the nematode Hadjelia truncata occurred in meat-type breeder rock pigeons (Columba livia) in southern and central California. Hadjelia truncata can infest several species of birds, although it has only been reported as pathogenic in pigeons. The factors that contribute to H.

Clostridium perfringens type C and Clostridium difficile co-infection in foals.

Clostridium perfringens type C is one of the most important agents of enteric disease in newborn foals. Clostridium difficile is now recognized as an important cause of enterocolitis in horses of all ages. While infections by C.

Pathology of Clostridium perfringens type C enterotoxemia in horses.

Clostridium perfringens type C is an important cause of enteritis and enterocolitis in foals and occasionally in adult horses. The disease is a classic enterotoxemia, and the enteric lesions and systemic effects are caused primarily by beta toxin, 1 of 2 major toxins produced by C. perfringens type C.

Determination of T1 relaxation time of normal equine tendons using magic angle magnetic resonance imaging.

Seven isolated equine front limbs were used to establish the normal T1 relaxation time of equine superficial digital flexor tendon (SDFT), deep digital flexor tendon (DDFT), and suspensory ligament (SL) using magic angle magnetic resonance (MR) imaging. MR imaging of the metacarpi was performed with the limbs positioned at 55° (the magic angle) relative to the main magnetic field. Transverse spin-echo proton density and inversion recovery images were acquired.
