When people usually talk about bacteria, most often they speak of them with a clearly negative connotation – however, in fact, to maintain good health, we need some strains and types of bacteria. So, specialists from the University of Michigan in the USA became interested in finding a possible correlation between certain bacterial colonies and the risk of developing various diseases in certain situations. The focus of their research was the question of what types of bacteria in the nasopharynx can cause a higher degree of sensitivity and susceptibility to colds and a number of other symptomatic diseases.
First of all, the experts armed themselves with the Nicaraguan Household Transmissions database, which is statistics on patients with various forms of colds and certain bacterial colonies – these statistics were compiled from 2012 to 2014 and included more than 700 participants. Then they carefully examined their “bacterial nature” of the nasopharynx and found out some really interesting points. They found that the majority of patients with chronic vulnerability to diseases of the nasopharynx have the so-called fourth bacterial group of the CST family. This family is a collection of beneficial bacteria that regulate microprocesses in the nasopharynx.
It was CST-4 that became the most common recognizable pattern and symptom in the affairs of those database patients who constantly suffered from various diseases of the nasopharynx, including chronic runny nose and inflammation of the mucous membrane. This finding suggests that the useful and harmful properties of this group of bacteria can be reversible.
However, it is still not entirely clear how exactly one property is transferred to another and whether any other third-party features are involved here – because in this case the study will need to be supplemented with some tools and approaches. In any case, the results of the presented study demonstrate that even beneficial bacteria can be dangerous in other cases.
