Leifsonia xyli subsp. xyli is the bacterium that causes ratoon stunting disease, a major worldwide disease of sugarcane. [1] [2] It is Gram positive and grows slowly in the laboratory.
Ratoon stunting disease is the most economically important disease of sugarcane, and is found in most sugarcane growing areas of the world. It can cause yield losses of up to 30% in susceptible varieties. The disease is difficult to identify and is transmitted mechanically or through infected seeds. [3]
Leifsonia xyli has a genome that contains 2.58 Mbp with 2,044 protein coding genes. [4]
The Thermoproteota are prokaryotes that have been classified as a phylum of the Archaea domain. Initially, the Thermoproteota were thought to be sulfur-dependent extremophiles but recent studies have identified characteristic Thermoproteota environmental rRNA indicating the organisms may be the most abundant archaea in the marine environment. Originally, they were separated from the other archaea based on rRNA sequences; other physiological features, such as lack of histones, have supported this division, although some crenarchaea were found to have histones. Until recently all cultured Thermoproteota had been thermophilic or hyperthermophilic organisms, some of which have the ability to grow at up to 113 °C. These organisms stain Gram negative and are morphologically diverse, having rod, cocci, filamentous and oddly-shaped cells.
The Chlamydiota are a bacterial phylum and class whose members are remarkably diverse, including pathogens of humans and animals, symbionts of ubiquitous protozoa, and marine sediment forms not yet well understood. All of the Chlamydiota that humans have known about for many decades are obligate intracellular bacteria; in 2020 many additional Chlamydiota were discovered in ocean-floor environments, and it is not yet known whether they all have hosts. Historically it was believed that all Chlamydiota had a peptidoglycan-free cell wall, but studies in the 2010s demonstrated a detectable presence of peptidoglycan, as well as other important proteins.
The Xanthomonadales are a bacterial order within the Gammaproteobacteria. They are one of the largest groups of bacterial phytopathogens, harbouring species such as Xanthomonas citri, Xanthomonas euvesicatoria, Xanthomonas oryzae and Xylella fastidiosa. These bacteria affect agriculturally important plants including tomatoes, bananas, citrus plants, rice, and coffee. Many species within the order are also human pathogens. Species within the genus Stenotrophomonas are multidrug resistant opportunistic pathogens that are responsible for nosocomial infections in immunodeficient patients.
In taxonomy, Ruegeria is a genus of the Rhodobacteraceae. This genus was formerly known as the marine Agrobacterium before they were reclassified in 1998. It bears in fact the name of Hans-Jürgen Rüger, a German microbiologist, for his contribution to the taxonomy of marine species of Agrobacterium.
Treponema is a genus of spiral-shaped bacteria. The major treponeme species of human pathogens is Treponema pallidum, whose subspecies are responsible for diseases such as syphilis, bejel, and yaws. Treponema carateum is the cause of pinta. Treponema paraluiscuniculi is associated with syphilis in rabbits. Treponema succinifaciens has been found in the gut microbiome of traditional rural human populations.
Methanococcus is a genus of coccoid methanogens of the family Methanococcaceae. They are all mesophiles, except the thermophilic M. thermolithotrophicus and the hyperthermophilic M. jannaschii. The latter was discovered at the base of a “white smoker” chimney at 21°N on the East Pacific Rise and it was the first archaeal genome to be completely sequenced, revealing many novel and eukaryote-like elements.
Mycobacterium celatum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Xanthomonas is a genus of bacteria, many of which cause plant diseases. There are at least 27 plant associated Xanthomonas spp., that all together infect at least 400 plant species. Different species typically have specific host and/or tissue range and colonization strategies.
Clavibacter is a genus of aerobic Gram-positive bacteria.
Abiotrophia is a genus of lactic acid bacteria, a family in the phylum Bacillota (Bacteria).
Mobiluncus is a genus of Gram-positive, anaerobic, rod-shaped bacteria. These bacteria may be stained either Gram-negative or Gram-variable. However, they are classified as Gram-positive rods due to the fact that they possess a Gram-positive cell wall, lack endotoxin and are sensitive to vancomycin, erythromycin and ampicillin, but resistant to colistin.
Leifsonia is a Gram-positive genus of bacteria from the family Microbacteriaceae.
Mycobacterium peregrinum is a species of Mycobacterium.
Polynucleobacter necessarius is a bacterium of the genus Polynucleobacter.
Mobiluncus mulieris is a curved, anaerobic bacteria from the vagina of women. Its cells are motile and rod-shaped, having multiple subpolar flagella and multilayered gram-variable cell walls. Its type strain is ATCC 35243. It is often associated with vaginal infections.
Rathayibacter toxicus is a phytopathogenic bacterium known for causing annual ryegrass toxicity (ARGT) commonly found in South and Western Australia.
Trueperella pyogenes is a species of nonmotile, facultatively anaerobic, Gram-positive bacteria. The cells typically measure 0.5 by 2.0 μm. They appear as pleomorphic or coccoid rods. They tend to be grouped singly or in short chains but are sometimes grouped into V-shaped pairs.
The Coriobacteriia are a class of Gram-positive bacteria within the Actinomycetota phylum. Species within this group are nonsporulating, strict or facultative anaerobes that are capable of thriving in a diverse set of ecological niches. Gordonibacter species are the only members capable of motility by means of flagella within the class. Several species within the Coriobacteriia class have been implicated with human diseases that range in severity. Atopobium, Olsenella, and Cryptobacterium species have responsible for human oral infections including periodontitis, halitosis, and other endodontic infections. Eggerthella species have been associated with severe blood bacteraemia and ulcerative colitis.
Clavibacter nebraskensis is a species of bacteria in the genus Clavibacter. It causes wilt and blight in maize, called Goss's wilt.
Leifsonia xyli is a Gram-positive species of bacteria from the family Microbacteriaceae.
