Focal and generalized alopecia.

Focal or generalized alopecia is defined as hair loss affecting the ventral, lateral, perineal, and dorsal aspects of the trunk of the cat, usually in a symmetric pattern. This may be attributable to failure of hair coat production, excess loss of hair due to self trauma, or excess shedding of whole hairs. Self trauma is the most common cause of hair loss and is associated particularly with flea allergy dermatitis. Other causes of hair loss are reviewed.

Clinical aspects of Chlamydia psittaci infection in cats infected with feline immunodeficiency virus.

Two groups of six cats were established, one a control group and one infected with feline immunodeficiency virus (FIV) 18 months previously. The cats in both groups were inoculated with Chlamydia psittaci and the clinical progression of the infection was monitored by means of a clinical scoring system for 10 months. Haematological, serological and viral and chlamydial isolation studies were also made. The response of the FIV infected group to treatment with oxytetracycline was monitored in the 11th and 12th months. The FIV infection prolonged the duration of the clinical signs resulting from the infection with C psittaci and led to the development of chronic conjunctivitis. The haematological and antibody responses to C psittaci were comparable in the two groups. However, it was possible to isolate C psittaci from the FIV-infected cats up to day 270, when the treatment began, but only up to day 70 in the control group. In addition, it appeared that the infection with a secondary pathogen may have accelerated the clinical progression of the FIV infection.

Allergen-specific IgG antibodies in cats with allergic skin disease.

An enzyme-linked immunosorbent assay was developed for quantifying feline serum allergen-specific IgG directed against selected house dust, pollen and flea allergens. The assay was used to compare allergen-specific IgG concentrations in sera from healthy cats, cats with non-dermatologic illness, confirmed allergic cats and undiagnosed pruritic cats. Our results demonstrate that cats with confirmed allergic skin disease have significantly more IgG directed against house dust, flea and ryegrass allergens than other cat groups examined. These results support the theory that cats with allergic skin disease have an underlying TH2 lymphocyte response that directs production of both allergen-specific IgG and IgE.
