Burkholderia

The genus Burkholderia belongs to the so-called gram-negative non-fermenting bacteria, it belongs to this group together with the genus Burkholderia genera showing similar characteristics as this genus, they are the genus Pseudomonas and the genus Stenotrophomonas. Due to their common characteristics and traits, these genera can be put into context, in the medical sense, these genera are important mainly in terms of nosocomial diseases.

Taxonomy
The taxonomy of the genus Burkholderia is constantly renewed, the current classification is as follows:


 * class Betaproteobacteria ,
 * Order of the Burkholderiales ,
 * family Burkholderiaceae ,
 * Burkholderia mallei.jpg Burkholderia ,
 * The genus includes several species of bacteria, the most important of which include:
 * Burkholderia cepacia ,
 * Burkholderia mallei ,
 * Burkholderia pseudomallei.

Burkholderia cepacia
[✎ edit embedded article] Burkholderia cepacia is a bacterium originally parasitizing on garlic plants. It is currently gaining in importance as a causative agent of nosocomial infections. High resistance to hospital disinfectants such as Ajatin, Septonex or chlorhexidine makes it exceptional. The bacteria can bind atmospheric carbon dioxide and thanks to this property it can also multiply in distilled water. B. cepacia produces exo substances that damage macroorganisms.

It is especially dangerous for patients with artificial heart valves or vascular implants and for patients with cystic pulmonary fibrosis. Among other things, it contributes to infections of the urogenital tract of women caused by nosocomial transmission via a gel used for gynecological examination. Effective treatment has been demonstrated with piperacillin and its protected variants with tazobactam, as well as with ceftazidime , carbopenems or fluoroquinolones. Cultivation of Burkholderia cepacia is not demanding, but selective soils are used to exclude the growth of the Pseudomonas aeruginosa colony.

Burkholderia mallei
[✎ edit embedded article] Burkholderia mallei - microscopically Burkholderia mallei is an exception among other genera, it is a stationary gram-negative rod. It occurs mostly in the tropics and subtropics and can be brought to us from these areas. It causes a disease of solipeds called malleus. When transmitted to humans, it often has lethal consequences.

Burkholderia pseudomallei
[✎ edit embedded article] Burkholderia pseudomallei is atypical of our destination, occurring mainly in the tropics and subtropics of Southeast Asia, but also in northern Australia. This bacterium causes melioidosis or pseudomalleus in humans and animals. The course of the disease can be different, asymptomatic, chronic and acute. Untreated melioidosis is 95% fatal.
