This course will offer a practical approach to prescribing antibiotic therapy and development of antimicrobial stewardship across all specialties and settings. Antibiotics are among the most frequently prescribed classes of drugs and it is estimated that approximately 50% of antibiotic use, in both... the outpatient and inpatient settings, is inappropriate. At the same time, in contrast to any other class of drugs, every antibiotic use has a potential public health consequence – inappropriate use may not harm only the individual patient, but contributes to societal harm by exerting an unnecessary selective pressure that may lead to antibiotic resistance among bacteria. This video based course will introduce learners to the basic principles of appropriate antibiotic use, demonstrate how to apply these principles to the management of common infections, and outline how to develop and maintain an antimicrobial stewardship program.

Desde hace muchas décadas, los microbios, en particular las bacterias, se han vuelto cada vez más resistentes a diversos antimicrobianos. El aval de la Asamblea Mundial de la Salud al Plan de Acción Mundial sobre la resistencia a los antimicrobianos, en mayo de 2015, y la Declaración política d...e la reunión de alto nivel de la Asamblea General sobre la resistencia a los antimicrobianos, en septiembre de 2016, reconocen que la resistencia a los antimicrobianos es una amenaza para la salud pública mundial. Estas iniciativas políticas reconocen el uso excesivo e inapropiado de los antimicrobianos como el principal factor que favorece dicha resistencia, así
como la necesidad de optimizar el uso de estos medicamentos.

This chapter discusses the antibacterial treatment of leprosy infections. Antibiotic treatment is
a key component of leprosy treatment, as it is vital to prevent the progression of the infection.
Treatment with rifampin and other antibiotics is highly effective and cures 98% of patients with
the ...leprosy infection. Furthermore, the relapse rate is very low, at about 1% over 5–10 years.
There is little M. leprae drug resistance in leprosy and few reports of multi-drug resistance (1, 2, 3,
4, 5, 6, 7, 8). An antibiotic treatment may take months or years to produce clinical improvement,
especially in patients with an initial high bacterial index (BI).

This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector. The flagellate mainly colonizes the intestinal tract of the insect. The effect of triatomines on trypanosomes is indicated by susceptibility and refractoriness phenom...ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.

Antibiotics are only needed for treating certain infections caused by bacteria. Viral illnesses cannot be treated with antibiotics. When an antibiotic is not prescribed, ask your healthcare professional for tips on how to relieve symptoms and feel better.

Antibiotics are important medicines for the treatment of bacterial infections in humans and animals. Since their introduction in the 1940’s antibiotics have saved countless lives and has made many medical techniques possible or safer.
You don't always need antibiotics when you're sick—only for infections caused by bacteria. And overuse is causing a global health problem.

Antimicrobials are used in veterinary medicine to treat infectious diseases in animals caused or complicated by microorganisms, mainly bacteria, or to prevent the development or spread of infection in healthy animals.
