Bacterial Resistance: Origins, Epidemiology, and Impact

Antifungal drug resistance of yeasts in dermatology: mechanisms, epidemiology and clinical impact

Superficial dermatophytoses are among the most common infectious disease. The most commonly used antifungal categories reazoles, polyenes and echinocandins. Due to the limited number of available antifungal drugs, toxicity and the emergence of resistant (intrinsic or acquired) strains, antifungal strategy needs to be developed. Recently the researchers try to find alternative antifungal agents....

A bacterial antibiotic resistance gene with eukaryotic origins

points which are perpendicular to the lines of the distal stimulus. Thus, with a radiating pattern they are circular, and can be seen more readily within the orange annuli. If a white surface is observed following fixation on the pattern for around 30 seconds then scintillating dots will seem to be streaming in a direction orthogonal to the previously presented lines. Regular geometrical patter...

Origins of epidemiology.

In this paper we trace the history of epidemiology from 1800 to the present time. The history is highly selective because our purpose is to illuminate the evolving relationship of epidemiology with demography. We first describe the common "prehistory" of these two disciplines in the early nineteenth century, and then describe their divergence during three successive eras of epidemiology up to t...

Impact of vaccination on epidemiology of diphtheria and pertussis

Whooping cough and diphtheria are vaccine preventable diseases. Diphtheria, due to Corynebacterium diphtheriae or Corynebactium ulcerans, two Gram positive bacteria, is a serious upper respiratory tract disease with high morbidity and mortality rates. Vaccination, via an acellular vaccine composed only of purified, detoxified diphtheria toxin, has significantly reduced the incidence of the dise...
