(1) A limited population of bacteria which has became pathogenic was also sensitive to antibiotics to begin with.(2) Many important virulence factors associated with this organism are responsible for its extreme pathogenicity and high mortality rates.(3) Organisms of relatively low pathogenicity can present in a highly atypical fashion in immunosuppressed patients.(4) Whether M. tuberculosis loses pathogenicity as it acquires resistance to drugs is not known.(5) There is an assumption that tap water is free of any significant pathogenic bacterial counts.(6) Pattern recognition receptors recognise structures common to many microbial pathogens .(7) These findings show that the CMV subtypes may serve as a marker for pathogenicity and virulence of CMV strains.(8) The three pathogenous microbes include leptospira interrogans, epithelium glucocus gene and xanthomonas campestris pv. campestris.(9) A part of the stool sample was processed for the detection of bacterial pathogens .(10) Such changes may also happen within a class, especially for bacterial pathogens .(11) If this resistance then spreads to pathogenic bacteria these antibiotics will cease to be useful in a variety of infections.(12) Due to its extreme virulence and pathogenicity many casualties may result unless antibiotics are administered within 24 hours of the first symptoms.(13) The presence of potentially pathogenic bacteria from normal volunteers is of concern.(14) It is unlikely that viable pathogenic bacteria in sewage water could be dispersed in indoor air.(15) Symptoms and signs of influenza in children are not specific and can mimic a range of other common respiratory viral pathogens .(16) These, similarly, do not support combination therapy for specific pathogens , when detected.
