A systematic review of mammary gland inflammations in queens (Felis catus).

Mastitis is a rare condition that can be diagnosed in female cats of all breeds and ages. It is usually caused by bacterial agents and is frequently encountered secondarily in feline mammary fibroepithelial hyperplasia (FEH). If left untreated, it can peril both the queen and her kittens. Therefore, a reliable and quick diagnosis is the primary key to successful treatment. Conventional diagnosis consists of a clinical and ultrasound evaluation of the queen's mammary glands. However, there is a lack of literature specifically focused on mastitis in queens. Consequently, the present review brings forth the existing knowledge regarding mammary gland inflammations in cats, with the goal of improving current clinical evaluation and treatment plans.

Measurement of ITIH4 and Hp levels in bitches with pyometra using newly developed ELISA methods.

Measurement of acute phase proteins (APPs) as biomarkers in canine medicine is in increasing demand. In the present study, the development and validation of two ELISA methods for the quantification of canine inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4) and haptoglobin (Hp) are shown. The adequate imprecision and accuracy and wide analytical range make the developed methods appropriate to quantify ITIH4 and Hp in serum samples. The inter- and intra-assay CVs were lower than 10 %, and the assays maintained linearity under dilution and showed analytical equivalence with the method of radial immunodiffusion. The measurement of CRP, Hp and ITIH4 in sera from bitches affected by pyometra allowed us to determine that ITIH4 behaves as a moderate APP in dogs. The group of bitches affected by pyometra showed very high levels of CRP (147 ± 91 mg/L), corresponding to a strong inflammatory process, which resulted in a moderate increase in the concentrations of Hp (7 times) and ITIH4 (3 times) compared to the control group.
