Opportunistic pathogens are germs or microorganisms that are normally harmless, but when given the opportunity, can cause diseases or infections in individuals who have weakened immune systems or specific vulnerabilities.
Full definition
However, increased temperatures were quickly followed by a loss of resistance to pathogenic disease and an increased abundance of microbial pathogens in A. palmata [17], perhaps explaining the high incidence of disease following the thermal stress by either contagious or opportunistic pathogens [18].
If you are on immunosuppressing drugs remember that «IS treatment alters innate antimicrobial defenses and disrupts the gut microbiota, which leads to overgrowth of indigenous E. coli and facilitates colonization
by opportunistic pathogens.»
As pH shifts, prospects
for opportunistic pathogens increase, as does opportunities for gram - negative bacteria like Bacteroides and Enterobacter.
The research team discovered that the ancient human oral cavity carries
numerous opportunistic pathogens and that periodontal disease is caused by the same bacteria today as in the past, despite major changes in human diet and hygiene.
Well - controlled, experimental studies of the influence of microbial ecology, disinfectant type, pipe materials, and water age,
on opportunistic pathogen occurrence and persistence are needed in order to establish their relationships to drug resistance.»

opportunistic pathogen gene markers — Huan Li — Water Research
This human microbiome
includes opportunistic pathogens, microbes that do not normally cause disease in a healthy person but can provoke an infection when the person's immune system is suppressed, a concern known to occur during spaceflight.
They can shift the microbiome to restore normal commensal gut flora, suppress pathogenic overgrowths like Clostridia, and
squelch opportunistic pathogens through the use of quorum sensing.
Lactobacillus spp. could be considered a
potential opportunistic pathogen whenever there is disruption of the physiologic architecture of the intestinal mucosa, such as in abdominal surgery, endoscopic procedures, or enteric pathologies.
For example, Lactobacillus acidophilus, a lactic - acid producing bacteria that resides in the stomach, loves an acidic environment and will secrete adequate amounts of acid to maintain a pH that is intolerable for
many opportunistic pathogens.
[I] t is becoming clear that two
secondary opportunistic pathogens, specifically Pasteurella and Clostridia, are contributing to the rapid and wide - spread die - off.

of opportunistic pathogens and to monitor the efficacy of therapeutic remediation of GI disorders.
In addition to traditional zoonoses,
opportunistic pathogens such as Escherichia coli and staphylococci are exchanged between pets and humans sharing the same household.
The coughing up of green phlegm may be due to a worsening of symptoms (including additional infections
by opportunistic pathogens), without listening to the lung sounds it would be impossible to say if there is any improvement.
The team designated four new species groups within the genus; Francisella opportunistica,
an opportunistic pathogen of immune compromised patients; Francisella salina and Francisella uliginis, environmental isolates from coastal seawater near Galveston, TX; and Francisella frigiditurris from cooling - tower water in California.
Even so, there remains the possibility that it is not actually the killer but just
an opportunistic pathogen hitching a...
The combination of these factors could result in an increase of the infectious nature of
this opportunistic pathogen.
The OSU / OHSU College of Pharmacy teamed with the Oregon Health Authority and other collaborators on a two - year study of Acinetobacter baumannii,
an opportunistic pathogen associated primarily with infections among patients who have compromised immune systems and are in health care facilities.
The Actinobacteria phylum includes Corynebacterium and Propionibacterium; each genus was found in the ISS samples at a high level, which is «problematic,» says Venkateswaran, because they both have species that are
opportunistic pathogens.
«But the organisms that we detected as abundant in these biofilms appear to have characteristics that could be of interest because they are related to some bacteria that are
opportunistic pathogens that could pose a threat, especially to immunocompromised hospital patients»

an opportunistic pathogen because it will only infect an individual whose immune system does not work properly.
