(+info)Cohnella damensis sp. nov., a motile xylanolytic bacteria isolated from a low altitude area in Tibet. (6/41)
A bacterial strain, 13-25(T) with xylanolytic activity isolated from a single present soil sample, was characterized with respect to its phenetic and phylogenetic characteristics. The cells of the isolate are gram staining variable rods. The predominant fatty acids are anteiso-C(15 : 0), C(16-0), and iso-C(16 : 0), the major respiratory quinone is menaquinone (MK-7), with a polar lipid profile with unknown aminophospholipids. The G+C content is 54.3 mol%. The 16S rRNA gene sequence analysis indicates that this organism belongs to the genus Cohnella, with Cohnella panacarvi as the closest phylogenetic neighbor. Low levels of 16S rRNA gene sequence similarity (<97.0%) with respect to other taxa with published names and the identification of distinctive phenetic features in the isolate indicate that the strain 13-25(T) represents a novel species of the genus Cohnella, for which the name Cohnella damensis sp. nov. is proposed. The type strain is 13-25(T) (=CCTCC AB 208103(T) =KCTC 13422(T)). (+info)Fontibacillus panacisegetis sp. nov., isolated from soil of a ginseng field. (7/41)

(+info)Bacillales is an order of rod-shaped, gram-positive bacteria that are generally saprophytic and found in soil, water, and the gastrointestinal tracts of animals. The most well-known genus within this group is Bacillus, which includes several species that form endospores, allowing them to survive in harsh environments for long periods of time. Some members of Bacillales can cause food poisoning or other types of infection in humans, but many are also used in industrial and agricultural applications, such as the production of enzymes and antibiotics.
Phylogeny is the evolutionary history and relationship among biological entities, such as species or genes, based on their shared characteristics. In other words, it refers to the branching pattern of evolution that shows how various organisms have descended from a common ancestor over time. Phylogenetic analysis involves constructing a tree-like diagram called a phylogenetic tree, which depicts the inferred evolutionary relationships among organisms or genes based on molecular sequence data or other types of characters. This information is crucial for understanding the diversity and distribution of life on Earth, as well as for studying the emergence and spread of diseases.
"Paenibacillus" is a genus of gram-positive, rod-shaped bacteria that are commonly found in various environments such as soil, water, and the gastrointestinal tracts of animals. These bacteria are known to be facultatively anaerobic, which means they can grow in the presence or absence of oxygen. They are also known to produce endospores, which allow them to survive in harsh conditions for extended periods.
The name "Paenibacillus" comes from the Latin word "paene," meaning "almost" or "nearly," and the Greek word "bacillus," meaning "a small rod." This name reflects the fact that these bacteria were initially classified as members of the genus Bacillus, but were later reclassified due to their distinct characteristics.
Paenibacillus species have been found to be involved in a variety of industrial and agricultural processes, such as the production of enzymes, biofuels, and plant growth-promoting compounds. Some species are also known to cause infections in humans, particularly in individuals with weakened immune systems. However, such infections are relatively rare compared to those caused by other bacterial genera.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
Ambystomatidae is a family of salamanders commonly known as the mole salamanders. This family includes several genera and species of primarily North American salamanders, with a few species found in northeastern Asia. These amphibians are characterized by their fossorial (burrowing) habits and their external gills, which persist into adulthood in some species.
Mole salamanders typically have a stocky body and short limbs, with moist, smooth skin. They are generally found in forested areas, where they spend much of their time underground in burrows or beneath logs and rocks. Some mole salamander species are fully aquatic as adults, while others are terrestrial and return to the water only to breed.
One of the most well-known mole salamanders is the axolotl (Ambystoma mexicanum), a fully aquatic species that exhibits neoteny, meaning it retains its larval features throughout its entire life. The axolotl has become a popular subject for scientific research due to its ability to regenerate lost body parts.
Overall, Ambystomatidae represents an important family of salamanders with unique adaptations that allow them to thrive in various environments.
Endospore-forming bacteria are a group of Gram-positive bacteria that have the ability to form highly resistant structures called endospores under conditions of nutrient deprivation and environmental stress. The endospore is a dormant, metabolically inactive, and highly resistant structure that can survive extreme conditions such as high temperatures, radiation, and chemical exposure.
Endospores are formed through a process of sporulation, during which the bacterial cell undergoes a series of morphological and biochemical changes to produce a mature endospore. The endospore is composed of several layers that provide protection and structural support, including a thick cortex, a coat, and an exosporium.
Endospore-forming bacteria are widely distributed in the environment, including in soil, water, and air. Some notable examples of endospore-forming bacteria include members of the genera Bacillus and Clostridium, which include important human pathogens such as Bacillus anthracis (causes anthrax) and Clostridium tetani (causes tetanus).
The ability to form endospores is a survival strategy that allows these bacteria to persist in harsh environments and resist destruction by various physical and chemical agents. However, the formation of endospores can also make it difficult to eradicate endospore-forming bacteria from contaminated surfaces or medical equipment.
Biotechnology is defined in the medical field as a branch of technology that utilizes biological processes, organisms, or systems to create products that are technologically useful. This can include various methods and techniques such as genetic engineering, cell culture, fermentation, and others. The goal of biotechnology is to harness the power of biology to produce drugs, vaccines, diagnostic tests, biofuels, and other industrial products, as well as to advance our understanding of living systems for medical and scientific research.
The use of biotechnology has led to significant advances in medicine, including the development of new treatments for genetic diseases, improved methods for diagnosing illnesses, and the creation of vaccines to prevent infectious diseases. However, it also raises ethical and societal concerns related to issues such as genetic modification of organisms, cloning, and biosecurity.
Gram-positive endospore-forming bacteria are a type of bacteria that possess certain characteristic features.
1. Gram-Positive: These bacteria appear purple under the microscope when stained using the Gram stain technique, which differentiates bacterial types based on their cell wall composition. Gram-positive bacteria have a thick peptidoglycan layer in their cell walls and teichoic acids, making them retain the crystal violet stain used in this process.
2. Endospore-Forming: These bacteria can form endospores under adverse environmental conditions, such as extreme temperatures, pH levels, or nutrient deprivation. Endospores are highly resistant, dormant structures that contain DNA and some essential enzymes. They can survive in harsh environments for extended periods and germinate into vegetative cells when conditions improve.
These bacteria include several pathogenic species, such as Bacillus anthracis (causes anthrax), Clostridium tetani (causes tetanus), and Clostridium botulinum (produces botulinum toxin). Proper identification and understanding their characteristics are crucial for developing effective infection control measures, treatment strategies, and prevention methods.
"Bees" are not a medical term, as they refer to various flying insects belonging to the Apidae family in the Apoidea superfamily. They are known for their role in pollination and honey production. If you're looking for medical definitions or information, please provide relevant terms.
'Bacillus thuringiensis' (Bt) is a gram-positive, soil-dwelling bacterium that produces crystalline parasporal proteins during sporulation. These proteins are insecticidal and have the ability to kill certain insects when ingested. Different strains of Bt produce different types of insecticidal proteins, allowing them to target specific insect pests.
Bt is widely used in organic farming and integrated pest management programs as a natural alternative to chemical pesticides. It can be applied as a spray or incorporated into the genetic material of crops through biotechnology, producing transgenic plants known as Bt crops. These crops express the insecticidal proteins and protect themselves from specific pests, reducing the need for external applications of Bt formulations.
Bt is considered safe for humans, animals, and non-target organisms when used properly, as the parasporal proteins are not toxic to them. However, misuse or overreliance on Bt can lead to resistance development in target pests, reducing its effectiveness.
Biological pest control, also known as biocontrol, is a method of managing or eliminating pests such as insects, mites, weeds, and plant diseases using natural enemies or other organisms. These biological control agents include predators, parasites, pathogens, and competitors that regulate pest populations and reduce the need for chemical pesticides. Biological pest control is a key component of integrated pest management (IPM) programs and has minimal impact on the environment compared to traditional pest control methods.
Hemolysins are a type of protein toxin produced by certain bacteria, fungi, and plants that have the ability to damage and destroy red blood cells (erythrocytes), leading to their lysis or hemolysis. This results in the release of hemoglobin into the surrounding environment. Hemolysins can be classified into two main categories:
1. Exotoxins: These are secreted by bacteria and directly damage host cells. They can be further divided into two types:
* Membrane attack complex/perforin-like proteins (MACPF): These hemolysins create pores in the membrane of red blood cells, disrupting their integrity and causing lysis. Examples include alpha-hemolysin from Staphylococcus aureus and streptolysin O from Streptococcus pyogenes.
* Enzymatic hemolysins: These hemolysins are enzymes that degrade specific components of the red blood cell membrane, ultimately leading to lysis. An example is streptolysin S from Streptococcus pyogenes, which is a thiol-activated, oxygen-labile hemolysin.
2. Endotoxins: These are part of the outer membrane of Gram-negative bacteria and can cause indirect hemolysis by activating the complement system or by stimulating the release of inflammatory mediators from host cells.
Hemolysins play a significant role in bacterial pathogenesis, contributing to tissue damage, impaired immune responses, and disease progression.
Endotoxins are toxic substances that are associated with the cell walls of certain types of bacteria. They are released when the bacterial cells die or divide, and can cause a variety of harmful effects in humans and animals. Endotoxins are made up of lipopolysaccharides (LPS), which are complex molecules consisting of a lipid and a polysaccharide component.
Endotoxins are particularly associated with gram-negative bacteria, which have a distinctive cell wall structure that includes an outer membrane containing LPS. These toxins can cause fever, inflammation, and other symptoms when they enter the bloodstream or other tissues of the body. They are also known to play a role in the development of sepsis, a potentially life-threatening condition characterized by a severe immune response to infection.
Endotoxins are resistant to heat, acid, and many disinfectants, making them difficult to eliminate from contaminated environments. They can also be found in a variety of settings, including hospitals, industrial facilities, and agricultural operations, where they can pose a risk to human health.
I'm sorry for any confusion, but "Lepidoptera" is not a medical term. It is a taxonomic order that includes moths and butterflies, which are insects known for their distinctive wing scales. This term is used in the field of biology, not medicine.
Bacterial toxins are poisonous substances produced and released by bacteria. They can cause damage to the host organism's cells and tissues, leading to illness or disease. Bacterial toxins can be classified into two main types: exotoxins and endotoxins.
Exotoxins are proteins secreted by bacterial cells that can cause harm to the host. They often target specific cellular components or pathways, leading to tissue damage and inflammation. Some examples of exotoxins include botulinum toxin produced by Clostridium botulinum, which causes botulism; diphtheria toxin produced by Corynebacterium diphtheriae, which causes diphtheria; and tetanus toxin produced by Clostridium tetani, which causes tetanus.
Endotoxins, on the other hand, are components of the bacterial cell wall that are released when the bacteria die or divide. They consist of lipopolysaccharides (LPS) and can cause a generalized inflammatory response in the host. Endotoxins can be found in gram-negative bacteria such as Escherichia coli and Pseudomonas aeruginosa.
Bacterial toxins can cause a wide range of symptoms depending on the type of toxin, the dose, and the site of infection. They can lead to serious illnesses or even death if left untreated. Vaccines and antibiotics are often used to prevent or treat bacterial infections and reduce the risk of severe complications from bacterial toxins.
