RESUMEN
We found a low prevalence (0.6%) of carbapenemase-producingEnterobacteriaceae(CPE) in fecal microbiota of companion dogs. A single VIM-1-producingKlebsiella pneumoniaeisolate belonging to sequence type (ST) 2090 was detected.blaVIM-1was carried on a class 1 integron and an untypeable â¼48-kb plasmid. Emergence and spread of CPE in this group of animals may be a threat to public health in human and veterinary medicine. This finding supports the need for active surveillance studies in companion animals that live close to humans, as interspecies transmission may occur within the same household.

The discovery, commercialization and administration of antibiotics revolutionized the world of medicine in the middle of the last century, generating a significant change in the therapeutic paradigm of the infectious diseases. Nevertheless, this great breakthrough was soon threatened due to the enormous adaptive ability that bacteria have, through which they are able to develop or acquire different mechanisms that allow them to survive the exposure to antibiotics. We are faced with a complex, multifactorial and inevitable but potentially manageable threat. To fight against it, a global and multidisciplinary approach is necessary, based on the support, guidance and training of the next generation of professionals. Nevertheless, the information published regarding the resistance mechanisms to antibiotics are abundant, varied and, unfortunately, not always well structured. The objective of this review is to structure the, in our opinion, most relevant and novel information regarding the mechanisms of resistance to antibiotics that has been published from January 2014 to September 2019, analysing their possible clinical and epidemiological impact.

INTRODUCTION: The aim of this study was to determine the prevalence of Mycoplasma genitalium infection and the resistance to macrolides within a general population in Madrid in 2015. METHODS: We collected 359 urine samples from a general population with symptoms of sexually transmitted infections (STIs). All samples underwent a real-time PCR. For the detection of macrolide resistance, a 283bp fragment of region V of the 23S rRNA gene of M. genitalium was amplified and sequenced. RESULTS: We found a prevalence of 3.34% of M. genitalium and a macrolide resistance rate of 20%. In males, the prevalence was 6.62% and in women 0.96%, being significantly higher in males. CONCLUSIONS: The prevalence obtained shows that it is a pathogen to consider in our environment. These findings stress the need for routine testing of M. genitalium infections and would seem to suggest the advisability of resistance testing.
