A previous study showed that IgG antibodies may be remarkably stable in decomposed lung tissue samples which had been stored for 48 days and were overgrown with bacteria and fungi [ 14].
Despite becoming overgrown by other bacteria, both the Lactobacillus and the Acetobacter related phylotypes remained present in minor proportions during the entire experimental time.
It is catalase, oxidase, and urease negative and is easily overgrown by other bacteria, which are often found concomitantly.
As this pathogen is difficult to detect in the laboratory and is easily overgrown by other bacteria, awareness of its existence is crucial as not to underestimate its presence.
The static mucus in the CF mouse small intestine becomes overgrown with colonic-type bacteria which upregulate some innate defenses, including a dramatic influx of mast cells [ 9] and altered prostaglandin metabolism [ 13].
At the same time point, embryos in the Pu.1 morpholino-injected control group were completely overgrown with infection, with the bacteria spreading throughout the entire vasculature (Fig. 5F).
The slow growing nitrifying bacteria will be overgrown and pushed down to oxygen limited layers by the faster growing heterotrophs (Elenter et al. 2007 ; Gonenc and Harremoes 1990 ).
Because of lactobacilli are the predominant species vaginally, they can be easily overgrown by the predominant rectal bacteria as they represent about 0,01% of the overall cultivable bacterial intestinal population [ 39, 40].
Furthermore, it is often overgrown by faster-growing commensal and pathogen bacteria.
In addition slow growing bacteria such as A. schaalii can get overgrown by faster-growing bacteria and therefore remain undetected.
On the other hand, PCR-based methods could detect bacteria that were inhibited in their growth by residual concentrations of antimicrobials in the sample [ 31], overgrown by other bacteria present in the sample, autolyzed during incubation [ 32], or difficult to cultivate in vitro [ 33], and are thus under-diagnosed by bacterial culture.
