Los perros son las mascotas más cosmopolitas de los humanos y, como tales, un medio de transmisión zoonótica de parásitos a sus cuidadores o dueños. Por ello el objetivo del estudio fue evaluar la epistemología de parásitos gastrointestinales en caninos del Centro de Rescate Integral Animal Riobamba (CRIAR. Fueron muestreados 40 perros de ambos sexos y clínicamente sanos. Las muestras fecales se sometieron a dos técnicas de análisis, la flotación salina en solución salina saturada para la identificación de especímenes mediante y la técnica de McMaster modificada para la cuantificación de los ooquistes/óvulos por gramo de heces (HPG-OPG). Se detectaron ocho especies diferentes de parásitos gastrointestinales, siendo tanto Uncinaria stenocephala como Ancylostoma sp. las más abundantes, con una prevalencia del 30% y 22.5%, respectivamente, estando presentes también las especies Cystoisospora canis (17.5%) y Toxocara canis (12.5%). Para el caso de Capillaria aerophila la prevalencia fue del 7.5% y en Cryptosporidium parvum (5%). Con menor frecuencias se identificaron casos infectados con Giardia lamblia y Echinococcus granulosus con una prevalencia del 2.5% en ambos casos. La infección concurrente con más de una especie de parásitos gastrointestinales fue un hallazgo común en perros. Se evidencia la necesidad de mejorar la atención veterinaria del CRIAR. Además, de definir los factores de riesgo de transmisión de helmintos zoonóticos a humanos, y plantear programas de educación pública sobre el cuidado adecuado de los perros, la higiene personal por parte de los adiestradores y propietarios de caninos.

“…Although some researchers have raised concerns with attempting to describe reinforcement in the absence of a contingency (see Carr, 1996; Poling & Normand, 1999; Staddon, 1992; Vollmer, 1999), the use of the term NCR and of such schedules to reduce aberrant or undesired behaviors have become commonplace (for reviews, see Carr et al, 2000; Ingvarsson & Fernandez, 2023). During the last couple of decades, applied research efforts involving response‐independent schedules with animals have emerged including with a black vulture ( Coragyps atratus ; Morris & Slocum, 2019), polar bears ( Ursus maritimus ; Fernandez, 2010; Fernandez, 2021), and domestic dogs ( Canis familiaris ; Hall et al, 2015; Pfaller‐Sadovsky et al, 2022; Protopopova & Wynne, 2015). Additionally, response‐independent schedules have been used as an experimental control procedure in applied animal behavior research, contrasting the effects of noncontingent food with food delivered contingent on specific approximation steps in a shaping program (Fernandez, 2020; Fernandez & Rosales‐Ruiz, 2020).…”

Response-independent schedules involve the delivery of an item independent of a response requirement. Often described in the applied behavior analytic literature as "noncontingent reinforcement," they have also frequently been used to reduce undesired or problematic behaviors. The current study examined the use of an automated response-independent food schedule on the behaviors and sound levels of shelter dogs. Several dogs were included in a 6-week reversal design, where a fixed-time 1 min schedule was compared with a baseline condition. Eleven behaviors were measured, as were two areas of each kennel and the overall and session sound intensity (dB) that occurred during the study. The results demonstrated that the fixed-time schedule increased overall activity while decreasing inactivity and led to a reduction in the overall sound intensity measured. Session and hour-tohour sound-intensity data were less clear, suggesting a potential contextual conditioning effect as well as a need for adjusted methods to study shelter sound. The above are discussed in terms of their potential welfare benefits for shelter dogs as well as the translational approach that this and similar research could contribute to the application and functional understanding of response-independent schedules.
