Saprophytic colonization

In the nonimmunocompromised host, Aspergillus infections of the sinuses most commonly occur as saprophytic colonization (aspergillomas, or... 

Saprophytic colonization is found with increased incidence in patients with underlying pulmonary diseases, such as in advanced stages of chronic obstructive pulmonary disease, chronic asthma requiring administration of adrenal corticosteroids, primary ciliary dyskinesia syndrome and cystic fibrosis [4-7]. A.fumigatus is the predominant species cultured from the respiratory tract although other Aspergillus species may also be found occasionally. 

Aspergillosis may also develop within the spine (Fig. 3.36), within the pelvis, with tubo-ovarian masses or ureteral compression, or within the renal graft, as a fungus ball (saprophytic colonization of a cavity by fungal hyphae, without invasion of the adjacent tissues) (Johnston et al. 2004). 

The influence of leaf pathogens on the saprophytic microflora has been insufficiently examined, but Stadelman and Schwinn (99) showed that lesion areas on scabby apple leaves contained between the orders of 10-100 fold the microbes than did non-scabby portions. Presumably the microflora were altered qualitatively. Changed patterns of microbial colonization have implications for bioherbicide applications, eg. in the role that opportunistic microbes may play in invasion and death of leaves. 

Staph, aureus and a limited number of Staph, albus, while the nasopharynx is often colonized by streptococci of the viridans group, Strep, salivarius or Neisseria pharynges. Occasionally, pathogens such as Haemophilus influenzae and Klebsiella pneumoniae may be present. The most common organisms secreted during normal respiratory function and speech are saprophytic streptococci of the viridans group. 

The total nutrition of unicellular algae is normally inorganic. These organisms are autotrophic—their only disability relative to the saprophytic chain of events in the soil is that colonization of a substrate is confined to regions where light is available. Thus, within these limitations, the fungal... 

Saprophytic aspergillosis, consisting of fungal growth without tissue invasion. Examples include airway colonization as in asthma, cystic fibrosis, and COPD mycetoma or an invasion of necrotic tissue, usually the infarcted lung.
