Introduction. Snakebite envenoming is a relevant public health problem, and, in Colombia, it was included as a mandatory notification event since 2004. Because it is a tropical country with great ecosystem diversity, it occupies third place in Latin America, after Mexico and Brazil, reaching the highest number of snakebites. Objective. ⋯ Seventy- eight point thirteen per cent of the municipalities made some notification. A pattern of constant increase in the case number during the 10 years is evident, with exception of 2017; the sociodemographic characteristics are maintained. Conclusions. The municipality of San Andrés de Tumaco, the masculine gender and the rural areas are mostly affected by snakebites, caused mainly by the Bothrops genus and the highest snakebite incidence was seen in July.

Introduction: Infections associated with health care caused by S. aureus and coagulase-negative Staphylococci multi-resistant to antibiotics cause a high epidemiological impact due to their high morbidity and mortality. Biofilm formation, which has been associated with antimicrobial resistance, can also occur. Objectives: To determine methicillin resistance and to quantify the biofilm production to establish if there is a relationship in clinical isolates of S. aureus and coagulase-negative Staphylococci. Material and methods: A total of 11 strains of S. aureus and 12 of coagulase-negative Staphylococci were studied. Methicillin resistance was determined with cefoxitin discs and the Clinical Laboratory Standards Institute (CSLI), 2018 reference values. ⋯ No association was found between methicillin-resistance and biofilm formation. Conclusions: Cefoxitin is enough to define the resistance phenotype and is associated with the mecA genotype. All strains formed biofilms and were related to the presence of the icaADCB operon. Biofilm formation and methicillin resistance were independent features in both groups of strains.

Introduction. Unjustified authorship or “gift authorship” is an inadequate practice of authorship that consists of naming as authors people who do not meet the authorship criteria. Reports of scientific research are often published as original articles in scientific journals and may present these inappropriate practices. Objectives. ⋯ The critreria least met were the final approval of the manuscript (23.2%) and the writing and critical review of this manuscript. (16.8%). Conclusions. It is necessary that educational institutions train researchers to distinguish between authorship and contribution. In addition, it is necessary that the journals request and corroborate the reported contributions.

Rocky Mountain spotted fever is a highly lethal infectious disease, particularly if specific treatment with doxycycline is given belatedly. ⋯ Rocky Mountain spotted fever remains as one of the most lethal infectious diseases, which may be related not only to the lack of diagnostic suspicion and delayed administration of doxycycline, but to genotypic characteristics of Rickettsia rickettsii that may play a role in the variability of the fatality rate that has been reported in other geographical regions where the disease is endemic.
