Feline chlamydia is a disease caused by Chlamydophila felis, the etiologic agent of feline respiratory complex (FRC) and considered the primary pathogen of conjunctivitis in cats. The objective of the study was to determine the prevalence of the disease in cat patients at a veterinary clinic in the region of Ñuble, Chile, and its association with the variables sex, age group and history of FRC. A blood sample was taken from 60 feline patients who were randomly selected from the total number of registered clinical records. The diagnostic technique used was the immunoenzymatic test ImmunoComb® (sensitivity: 94.7%, specificity: 100%). The seroprevalence of Chlamydophila felis was 51.7% (31/60), with no significant differences by sex, age group, and history of FRC. The results showed the presence of antibodies against Chlamydophila felis in domestic feline patients in the study area.

The study aimed to detect the presence of endoparasites in faecal samples of Trachemys. scripta elegans from private households in the Maule Region, Chile. The sampling was conducted to determine the prevalence of gastrointestinal parasites in 35 individuals (22 females and 13 males), using the Teuscher coproparasitic technique. Only one sample of a female turtle was positive (2.85%), corresponding to an undetermined species of coccidia.

Degenerative joint disease (DJD) is a non-inflammatory pathology and characterized to be progressive, structural, and functional. The transforming growth factor Beta 1 (TGF-β1) is a regulatory cytokine participating in the production and deposition of extracellular matrix in various tissues, including joint cartilage. The aim of the present study was to compare the concentrations of transforming growth factor β1 in canine synovial fluid with (n=12) and without DJD (n=11), determined by an ELISA test. The mean concentration of TGB-β1 in dogs without DJD was 16.8 ± 7.1 ng/ml, while in dogs with DJD it was 10.3 ± 3.5 ng/ml (p <0.05).

La enfermedad degenerativa articular (EDA) es una patología de carácter no inflamatorio en su origen, que se caracteriza en ser progresiva, estructural y funcional. El factor de crecimiento transformante Beta 1 (TGF-β1) es una citocina reguladora en la producción y depósito de matriz extracelular en varios tejidos, incluyendo el cartílago articular. El objetivo del presente estudio fue comparar las concentraciones del factor de crecimiento transformante β1 en líquido sinovial de caninos con (n=12) y sin EDA (n=11), determinado mediante una prueba de ELISA. La concentración media de TGB- β1 en perros sin EDA fue de 16.8 ± 7.1 ng/ml, mientras que en perros con EDA fue de 10.3 ± 3.5 ng/ml (p<0.05).

The parrots (Birds: Psitacidae), besides being one of the pets of greater increase in Chile in recent years, are important reservoirs of pathogens, including the zoonotic bacterium Chlamydophila psittaci. The objective of the study was to detect the presence of serum antibodies against C. psittaci in 30 parrots from three private breeding sites in the Biobío Region, through the detection of IgG antibodies by a commercial ELSA kit (ELISA InmunoComb®). Three adult parrots (3/24) were seropositive (10% prevalence) and none of the juveniles (0/6). The positive psitacids corresponded to an austral parakeet (Enicognathus ferrugineus), a slender-billed parakeet (Enicognathus leptorhynchus) and an Amazon parrot (Amazonas pretrei), all from the same hatchery. The first two species are native species of Chile.
