Coordinated virulence gene expression is critical for bacteria during the course of infection.
Therefore, tolerating and overcoming oxidative stress is critical to bacteria viability as well as for the establishment of a successful symbiotic infection [ 32, 78].
The different spacer sequences in the three CRISPR loci of the strain M18 indicate that M18 has developed specific features to combat various phage invasions in the rhizosphere environment, as spacer sequences are known to be critical for bacteria to resist foreign phage invasion [ 46, 47].
But by then, Mr. Ahmed and Baraa Sharaf al-Deen, another engineer at the ministry, had taken 14 critical samples -- bacteria levels, heavy metals, phosphates and other pollutants -- of a kind that had been impossible since the American-led invasion of Iraq last year.
Reducing MRSA infections is critical because these bacteria are difficult to treat and are common in healthcare settings, especially among ICU (intensive care unit) patients.
In a complaint filed Tuesday in federal court in Wisconsin, six consumers alleged that the company's top-selling Roundup herbicide has been falsely promoted as uniquely safe when it actually can have profound harmful impacts on human gut bacteria critical to good health.
Although phytoplankton is better known than marine bacteria, critical unknowns include smaller organisms, temporal and spatial variability, and the dynamics of species composition and harmful algal blooms [233].
Once intracellular replication of the pathogen has reached a critical point the bacteria induce host cell death, again by an unknown mechanism, and subsequently escape host cells to establish secondary infections [3].
When a critical density of bacteria is reached, intra- and inter-bacterial species cross-talk begins through a process commonly referred to as quorum sensing, which comprises changes in gene expression and post-translational modification of proteins that ultimately lead to expression of the biofilm phenotype [22], [23].
A critical task for bacteria is the preservation of the integrity of their cell wall.
