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.

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...

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...
