Durante el confinamiento por la pandemia de SARS-CoV-2 (COVID-19), se evaluó la efectividad de la enseñanza a distancia de los principios básicos de cirugía utilizando la plataforma Entorno Virtual de Aprendizaje (ENVIA). Participaron 209 estudiantes de la licenciatura en Medicina Veterinaria y Zootecnia, en su cuarto año de carrera. La instrucción se llevó a cabo de manera asincrónica, a través de foros, lecturas y podcast, también se realizaron sesiones sincrónicas mediante videoconferencia. Para evaluar el cambio en el nivel de conocimientos, se aplicó un cuestionario al inicio del curso (semana 1) y al final (semana 10), utilizando la plataforma de Formularios de Google™. Los estudiantes participaron de forma voluntaria, y solo se recopiló su dirección de correo electrónico institucional para vincular los cuestionarios inicial y final. Las preguntas del cuestionario abarcaron diferentes áreas de conocimiento: anestesia (10 %), asepsia (20 %), hemostasia (10 %), manejo delicado de tejidos (20 %) y sutura (40 %). En el cuestionario inicial, el promedio de calificación fue de 5 sobre 10; mientras que, en el final, de 8 sobre 10. Mediante la prueba de rangos firmados de Wilcoxon, se encontró una diferencia significativa (P < 0.0001) entre las calificaciones iniciales y finales. Se identificó la necesidad de reforzar los conocimientos en el manejo delicado de tejidos y sutura. Estos resultados indican que este modelo de enseñanza a distancia tiene el potencial de mejorar la eficacia del autoaprendizaje de los estudiantes en los principios básicos de cirugía.

A dog's emotional state is communicated primarily through body language, readily observable by humans and other animals. Additionally, dogs express visual and auditory signals differently according to the situation they are experiencing. However, there is a need for more research on smaller breeds since they tend to display more behavioral issues than larger breeds. The objective of the present study was to identify the behavioral characteristics of 25 dogs of three different small breeds (Chihuahua, Toy Poodle, and Miniature Schnauzer) in a negative context. We used a web-based tool called the Dog Actions Video Annotation Interface (DAVAI) to evaluate the movements of the tail, legs, snout, and vocalizations when the dogs were exposed to unfamiliar people. Our results showed no significant differences in dog behavior associated with breed. However, we identified variations in dog vocalizations explained by the sex, with male dogs whining more frequently than females. We highlight the importance of understanding dog body language and vocalizations, regardless of their breed. Our study is particularly relevant in negative contexts, where dogs may exhibit distress signals that require prompt intervention to alleviate their suffering.

The brown pelican (Pelecanus occidentalis californicus) is a migratory subspecies that nests on the islands of the gulf of California, in the Pacific Northwest. The objective of this study was to identify Chlamydia species in brown pelican samples obtained in 2016, 2017, and 2021. Samples were taken from the cloacae and choanae of 86 brown pelicans in specimens ranging from three to seven weeks of age. The samples were obtained with sterile swabs and transferred to an SPG growth medium. The DNA was extracted to carry out a real-time PCR that detects the gene of the 235 rRNA subunit of the Chlamydiaceae family. In addition, real-time PCR directed to the ompA gene was performed to determine the Chlamydia species. Of the 86 sampled pelicans, four were positive for the family Chlamydiaceae and Chlamydia abortus. This is the first report of C. abortus in brown pelicans from the gulf of California, Mexico.

The bioavailability (F) of calcium and other nutrients from the gastrointestinal tract in the second and third laying cycle hens and in hens under heat-stress is insufficient to sustain the necessary egg production. The administration of additional amounts of any source of calcium has been shown to be insufficient to meet the demand for calcium. However, improved calcium F has already been achieved in these hens if calcium carbonate is pharmaceutically prepared as patented pellets (FOLAs). Hence, clinical challenges were set to test the FOLA pellets as a form to sustain egg production and eggshell thickness in 180-second and 180-third cycle Bovans-White laying hens, randomly divided into six groups, as follows: cycle-2 control group (GCC2); FOLA-group-capsaicin (GFcC2); FOLA-group-capsaicin-turmeric powder-cinnamon powder (GfexC2); control-group for third cycle hens (GCC3); FOLA-group-capsaicin (GFcC3); FOLA-group-capsaicin-turmeric powder-cinnamon powder (GFexC3). This trial was carried out under moderate heat-stress conditions, and a follow-up was carried out utilizing eye thermographic measurements. The results show that all FOLA-fed hens of the second or third laying cycle presented better laying average and eggshell thickness than the untreated control groups, i.e., GFcC2 128 % higher than GCC2; GfexC2 135 % higher than GCC2; GFcC3 168 % higher than GCC3; and GFexC3 was 173 % higher than GCC3 (P < 0.01 in all comparisons). FOLA pellet formulation, similar to GfexC2, is postulated as a viable natural solution to counter the decreased egg-laying and shell thickness in second and third-cycle hens under moderate heat stress.

In this study, it was aimed to investigate the efficacy of O3 therapy in experimentally induced HF skin burns in rats. A total of 20 healthy male Wistar Albino rats (weighing 250-300 g, aged 16 weeks) were used as the material of the study. They were divided into two groups (as experimental and control groups) of 10 rats which were housed individually and fed ad libitum. Hydrofluoric acid (HF) skin burns were induced in all animals. The ozonized (20 µg O3/mL) liquid vaseline was applied topically for seven days to the experiment group as well as parallelly, a saline solution was applied to the control group. In the histopathologic evaluation, inflammation, vascularization, epithelial regeneration and fibrosis were evaluated. The epithelial proliferation and collagenization were higher and statistically significant in the experimental group, while the infiltration was higher and statistically significant in the control group. As a result of this study, it was observed that ozone plays an important role in the tissue repair process in chemical burns. The increase of fibroblast activation and re-epithelization in the experimental group demonstrated that ozone therapy could be suggested as first aid in HF skin burns. It was concluded that more studies on ozone are needed to shed light on the subject.

The aim of the study was to assess the effect of humic substances (HS) extracted from vermicompost on the growth performance, fecal score, bone ash content and antioxidant status in muscles and blood serum of weaned pigs from 1-42 days postweaning. Two-hundred 22-day weaned pigs were assigned to four treatments: 1= Positive control diet with colistin (PC), 2= Negative control diet without antibiotic or HS (NC), 3 and 4= Diets with 2 500 and 5 000 ppm of HS, respectively. Growth performance, fecal consistency, dry matter and ashes of metatarsus and the 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, iron reducing ability and thiobarbituric acid reactive substances in muscles and blood were registered. Results were subjected to ANOVA and regression analysis. Linear increasing responses (P < 0.05) were found in the body weight at 42 days postweaning, the ADG from 1-7, 8-21, 22-42 and 1-42 and the gain:feed ratio from 1-7, 22-42 and 1-42 days postweaning, whilst the fecal score decreased linearly (P < 0.01) from 1-7, 8-21 and 1-42 days postweaning due to the increasing dietary HS concentration. The antioxidant potential of 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity (P < 0.05) in loin muscle and blood serum at three and seven days, and in fillet muscle at seven days postweaning increased linearly due to the increasing dietary HS concentration. It is concluded that the addition of HS improved the growth performance from 1-42 days postweaning and the antioxidant status in muscles and blood serum of weaned pigs at three and seven days postweaning.

El hemangiosarcoma (HSA) es un tumor agresivo y maligno que se produce en las células del endotelio e invade los vasos sanguíneos, suele ser bastante común en caninos de 6 a 13 años de edad, pero ciertas razas como Pastor Alemán, Golden Retriever, Labrador y Bóxer presentan predisposición a padecerlo. Este puede producirse en cualquier parte del cuerpo del animal, pudiéndose encontrar en corazón, hígado, piel y huesos, aunque su localización más común es en el bazo. Su importancia radica en que son pocos los caninos que pueden ser diagnosticados antes de que el tumor sufra ruptura y provoque un fuerte sangrado abdominal, que conlleva a anemia, debilidad y colapso. El presente estudio ofrece una revisión actualizada de los diferentes métodos para su diagnóstico y tratamiento, con énfasis en la ontogenia, genética, mutaciones, vías de señalización y marcadores de gran importancia, como el CD133, CD117, CD45 y CD34, con el fin de realizar un diagnóstico oportuno a partir de la biología molecular y un tratamiento eficaz, para así aumentar el tiempo de supervivencia del canino con HSA. Asimismo, se busca lograr ampliar el panorama a los profesionales al momento de realizar una detección precoz del HSA, con el fin de disminuir el daño provocado al canino que es extremadamente traumático y doloroso en el transcurso de esta patología.

Asimismo, se busca lograr ampliar el panorama a los profesionales al momento de realizar una detección precoz del HSA, con el fin de disminuir el daño provocado al canino que es extremadamente traumático y doloroso en el transcurso de esta patología.","PeriodicalId":23475,"journal":{"name":"Veterinaria México OA","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139004680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pet transportation has become relevant. However, since adequate sanitary measures are not taken, pets can be carriers of pathogens, such as ticks which at the same time may turn into zoonotic agent vectors. Ticks are frequent ectoparasites in warm areas. However, they may be dispersed in temperate regions such as Mexico City (CDMX) and become responsible for other vector-borne diseases relevant to Veterinary Medicine and/or public health. It shows that moving animals from one place to another, including tourism with pets, can cause dispersion and proliferation of pathogens if the adequate sanitary measures are not taken. Therefore, this article is of great importance from a biological, ecological, public and veterinary health, since it shows the role of humans in the spread of pathogens particularly of Rhipicephalus sanguineus, its introduction to a site otherwise naturally free of them, and the adaptation mechanisms they may display to infect other hosts with the potential to transmit other emerging pathogens.

El botón de oro (Tithonia diversifolia (Hemsl.) A. Gray) es un forraje promisorio en ganadería de leche, debido al relativamente elevado contenido de proteína y carbohidratos no fibrosos; además, posee metabolitos secundarios que pueden modular la fermentación ruminal hacia vías metabólicas más eficientes para el animal y menos perjudiciales para el medio ambiente. El valor nutritivo del botón de oro por su estado fenológico ayuda a establecer estrategias de manejo que benefician el desempeño de los animales, sin perjudicar el forraje. Por otra parte, el afrecho de yuca es un subproducto de la extracción del almidón de yuca (Manihot esculenta Crantz) con potencial uso en alimentación de ganado lechero, por su elevada concentración de almidón. El proceso de ensilaje favorece el uso del botón de oro, pues permite cosecharlo de acuerdo con la edad fenológica, mantener estable la oferta de forraje y disminuir los costos de producción. Utilizar aditivos como azúcar, melaza y jugo fermentado de flora epífita pueden contribuir al proceso de fermentación ácido láctica y disminuir la pérdida de nutrientes durante la elaboración de ensilajes. Emplear afrecho de yuca al elaborar ensilaje de botón de oro, contribuye a la conservación del forraje porque disminuye la humedad y aporta carbohidratos de fácil fermentación. El ensilado mixto de botón de oro y afrecho de yuca benefician la alimentación del ganado lechero, debido al contenido de proteína y metabolitos secundarios del botón de oro, sumado al aporte de almidón del afrecho de yuca; sin embargo, esta hipótesis deber ser desafiada experimentalmente.
