The aim of this study was to determine the in vitro antibacterial activity of the hydroalcoholic extract of Dalea bicolor on bacteria of importance in public health. The antibacterial activity was determined by the Minimum Inhibitory Concentration (MIC) and the Minimum Bactericidal Concentration (MBC). It was determined that the hydroalcoholic extract of Dalea bicolor has inhibitory activity at concentrations of 3.12 to 12.5 mg/ml and bactericidal activity at 50 and 100 mg/ml and can be considered as an alternative for the treatment of infections associated with bacteria of importance in public health.

Se evaluó la actividad antibacteriana in vitro de tres extractos hidroalcohólicos obtenidos a partir de pulpa, semilla y hoja de Cyrtocarpa procera sobre bacterias ATCC (American Type Culture Collection) y aisladas de casos clínicos de importancia en salud veterinaria y pública. Los extractos se obtuvieron por maceración en una solución hidroalcohólica (70:30, agua: metanol). En los extractos se determinó el contenido de compuestos fenólicos totales. La actividad antibacteriana se determinó mediante la Concentración Mínima Inhibitoria (CMI) y Concentración Mínima Bactericida (CMB). Los extractos fueron evaluados a concentraciones de 200 a 1.56 mg/mL. El extracto de semilla tuvo un mejor efecto inhibiendo el crecimiento bacteriano sobre cepas de referencia y las aisladas de casos clínicos (CMI: 6.25-25 mg/mL), así como provocando la muerte bacteriana con una CMB de 25-200 ...

The Toxocara canis parasite represents a worldwide public health problem. This agent is an ascarid that, in its adult stage, lives in the small intestine of the domestic dog and several wild canids; it presents a complex biological cycle that ensures its transmission and permanence in the hosts it affects; in its intestinal phase, it causes mechanical, irritative and obstructive action, interfering in the transit and digestion of food. Toxocariasis affects young dogs and cats; it produces respiratory signs (cough due to migration of pulmonary larvae), growth retardation (emaciation, weakening of the coat and arthralgia) and intestinal disorders (alternating diarrhea and constipation, abdominal bulging, and vomiting). More intense prenatal infections in puppies can lead to severe disease with alternating diarrhea and constipation, vomiting, typical "pot belly," reduced growth with cachexi...

Rocky Mountain spotted fever (RMSF) is an acute infection characterized by febrile symptoms, caused by the bacteria Rickettsia rickettsii. The aim of this research was to determine the spatial and temporal distribution of RMSF in Mexico during the period 2015-2023. Information from the epidemiological bulletins of the National Epidemiological Surveillance System of Mexico (2015-2023) of the Ministry of Health of Mexico was analyzed. Prevalence rates of RMSF were calculated by state of the Mexican Republic, the temporal behavior of RMSF was determined through an endemic channel at the country level and by geographic area, and the spatial behavior was determined through the spatial statistic SCAN. The states with the highest prevalence rate of RMSF were Baja California and Sonora with more than 70 cases per 1,000,000 inhabitants. RMSF in the Mexican Republic occurs throughout the year, wit...

The objective of this study was to analyze cases of dogs diagnosed with strychnine poisoning at the Center for Research and Advanced Studies in Animal Health (CIESA), Mexico. This is a retrospective study based on information from cases that occurred between 2018 and 2021, in which clinical records from the toxicology department were analyzed and systematized. It should be noted that strychnine was identified in the laboratory using a qualitative test. A descriptive method was applied for reporting results, considering variables of epizootiological interest (geographical area of occurrence, type of sample, age, and breed of the affected animals). A total of 17 cases were received from the State of Mexico: Almoloya de Juárez (n = 3), Ixtlahuaca (n = 2), San Mateo Atenco (n = 1), Temoaya (n = 3), Toluca (n = 5), and Valle de Bravo (n = 1), and from the State of Querétaro (n = 2). In 2018...
