En el análisis de la información se refiere que la mosca del gusano barrenador del ganado (GBG), fue identificada en 1958 por Charles Coquerel. Cochliomyia hominivorax es un parásito que puede afectar tanto a los animales como al hombre. Su distribución histórica abarca desde EE. UU. hasta Sudamérica. Para 1959, la USDA inició su erradicación en EE. UU., lográndolo en 1966; sin embargo, han surgido brotes en África, el Caribe y Asia. En América Central, aunque se declaró erradicado en 2006, han reaparecido focos en países como Panamá, Costa Rica, Nicaragua y Honduras, con miles de casos reportados entre 2022 y 2025, lo que representa una amenaza para la salud animal y pública en la región. Con la creación de la Comisión México- Americana y el establecimiento de una planta productora de moscas estériles en Chiapas (1976), permitió como estrategia declarar libres del GBG a varios estados del sureste del país en 1991. Sin embargo, reaparece en México y se notifica en noviembre del 2024 en el estado de Chiapas, por lo que el incremento en el número de casos y el avance progresivo que representa esta problemática de interés zoosanitario se requiere la formulación de planes de contención, manejo y erradicación del territorio mexicano. La mosca del GBG afecta gravemente la salud y productividad animal. Deposita sus huevos en heridas, donde las larvas se alimentan de tejidos vivos, causa daño traumático, irritante y tóxico en los tejidos, generando necrosis, infecciones secundarias y riesgo de septicemia e infecciones y, en casos severos, la muerte. Su ciclo de vida se adapta al clima, que ocurre en 18 a 90 días según la temperatura. El diagnóstico de la cocliomiasis implica la inspección minuciosa de heridas en animales y humanos vulnerables, este se realiza mediante la extracción cuidadosa de larvas, su conservación en alcohol y posterior análisis morfológico y molecular (su identificación precisa es clave para un tratamiento y control adecuados). El diagnóstico diferencial del GBG se basa en distinguirla de otras especies de moscas causantes de miasis. El tratamiento incluye extracción de larvas, aplicación de larvicidas como ivermectina y cipermetrina. Para el control y prevención del GBG se requieren estrategias sanitarias, vigilancia epidemiológica y campañas educativas en zonas endémicas. Al aplicar barreras de defensa: requisitos zoosanitarios, monitoreo activo y respuesta ante brotes; así como acciones de cuarentena, tratamientos larvicidas, control de movilización y monitoreo de fauna silvestre, es factible lograr su control y erradicación del país. 2026-03-19T00:00:00Z http://hdl.handle.net/20.500.11799/143906 Proteinuria and Electrophoretic Pattern in Dogs with Comorbidities Associated with Chronic Kidney Disease Pérez-Sanchez, Alicia Pamela; PERINI PERERA, SOFIA; Del Ángel Caraza, J; QUIJANO HERNANDEZ, ISRAEL; Sergio Recillas-Morales, / In animals with chronic pathologies, the detection of proteinuria via the proteinuria: crea- tininuria ratio (UPC) and urinary protein electrophoresis allows for the early diagnosis of chronic kidney disease (CKD). The objective of this work was to identify and determine the magnitude of proteinuria and its electrophoretic pattern characterization in dogs with chronic diseases pathophysi- ologically related to proteinuria. With the studied patients, five groups were formed. The control group (CG) contained non-proteinuric cases. The cases with proteinuria were classified into four groups according to the concurrent disease: chronic inflammatory diseases (IG), neoplasms (NG), heart diseases (HG), and endocrine diseases (EG). For the statistical analysis, descriptive statistics and non-parametric tests were used. Data from 264 dogs were obtained; in the disease groups, proteinuria was observed in more than 30% as the only finding of kidney disease, evidencing a greater risk factor for proteinuria in the HG group (OR 4.047, CI 1.894–8.644, p < 0.0001). In the HG, NG, and EG groups, a higher frequency of glomerular pattern (GEP) related to glomerular hypertension was observed; in the IG, a higher frequency of mixed pattern (MEP) was observed. These findings are secondary to the hyperfiltration process that affects the glomerulus and the renal tubule. 2023-04-19T00:00:00Z http://hdl.handle.net/20.500.11799/143905 A Retrospective Study of Laparoscopic Cryptorchidectomy in 19 Cats with Intra-Abdominal Testes Villalobos Gomez, JJ; Del Ángel Caraza, J; Tapia Araya, A; Brandao, F; Hernández López, CA; Martínez Gomariz, FM; Botero Crespo, CE; Properzi, R Cryptorchidism is the failure of one or both testes to descend into the scrotum and remain there by 7–8 months of age and is considered the most common congenital disease in male dogs and cats. The prevalence of cryptorchidism in cats is 1.3–6.2%, and can be categorized as unilateral or bilateral and, depending on the location of the testes, as intra-abdominal, inguinal, or pre-scrotal. Due to the risk of testicular torsion, the development of testicular neoplasia and the fact that the cryptorchid testes still produce testosterone, cryptorchidectomy is the treatment of choice for these affected cats. For the intra-abdominal testes, a laparotomy for a caudal midline approach is generally recommended. However, laparoscopy in cryptorchidectomy in cats has been documented in a few clinical cases reports. The aim of the study was to report the short-term clinical outcomes for 19 cryptorchid cats with intra-abdominal testes that underwent cryptorchidectomy with laparoscopic techniques. The results of this study suggest that laparoscopic cryptorchidectomy is an appropriate procedure to treat cryptorchid cats, with all benefits of the minimal invasive surgery, such as a better visibility of abdominal structures, shorter hospitalization times, lower morbidity, less surgical site infections, and most importantly, minimized surgical pain and discomfort. 2023-01-03T00:00:00Z http://hdl.handle.net/20.500.11799/143904 Canine Silica Urolithiasis in Mexico, Associated with the Concentration of Dissolved Silica in Tap Water MENDOZA LOPEZ, CLAUDIA IVETH; Javier Del Ángel-Caraza, /; Aké-Chiñas, María Alejandra; QUIJANO HERNANDEZ, ISRAEL; Esteller Alberich, M. V. Silica urolithiasis is infrequent in dogs, but in Mexico represents 12.9%. Our hypothesis is the consumption of high amounts of silicates in the diet, especially that dissolved in tap water. The objective of this study was to determine the concentrations of silica in the tap water in different geographical areas and their relationship with cases of silicate urolithiasis in dogs. From 179 cases of silicate urolithiasis, 98.9% were from dogs within a geographic area called the Trans-Mexican Volcanic Belt, which represents a cross shaft to the center of the country. Silica concentrations in tap water ranged between 3 and 76 mg/L, with a range of 27 to 76 mg/L, a mean of 49.9 ± 12 mg/L within the Trans-Mexican Volcanic Belt, and a concentration from 3 to 30 mg/L, with a mean of 16.4 ± 7 mg/L outside this area; these were significantly different (p < 0.001). These findings demonstrate that there is a geographic risk factor for silicate urolithiasis in urolith-forming dogs, related to the consumption of tap water with a high concentration of silica. Further studies are necessary to identify this same pathophysiological association in other species. 2021-07-05T00:00:00Z
