Experimental contagious caprine pleuropneumonia: a long term study on the course of infection and pathology in a flock of goats infected with Mycoplasma capricolum subsp. capripneumoniae. (1/15)
Contagious caprine pleuropneumonia (CCPP) is a major threat to goat farming in parts of Africa and Asia. It classically causes acute high morbidity and mortality early in infection, but little is known of its long term epizootiology and course. In this study, 10 goats were inoculated with Mycoplasma capricolum subsp. capripneumoniae (M. capripneumoniae) and then mixed with 15 goats for contact transmission. The disease course was monitored in each goat for 56-105 days, whereafter the goats were killed and necropsied. Varying features signifying infection occurred in altogether 17 goats (7 inoculated, 10 in-contact). Clinical signs were severe in 8 goats but no fatalities occurred. Only 6 goats had serum antibody titres against M. capripneumoniae in ELISA. Fourteen goats (5 inoculated, 9 in-contact) had chronic pleuropulmonary lesions compatible with CCPP at necropsy and 7 of those showed M. capripneumoniae antigen in the lung by immunohistochemistry. Neither cultivation nor PCR tests were positive for the agent in any goat. The results indicate that the clinical course of CCPP in a flock may be comparatively mild, M. capripneumoniae-associated lung lesions may be present at a late stage of infection, and chronic infection may occur without a significant serological response. (+info)Versatile use of oriC plasmids for functional genomics of Mycoplasma capricolum subsp. capricolum. (2/15)
Replicative oriC plasmids were recently developed for several mollicutes, including three Mycoplasma species belonging to the mycoides cluster that are responsible for bovine and caprine diseases: Mycoplasma mycoides subsp. mycoides small-colony type, Mycoplasma mycoides subsp. mycoides large-colony type, and Mycoplasma capricolum subsp. capricolum. In this study, oriC plasmids were evaluated in M. capricolum subsp. capricolum as genetic tools for (i) expression of heterologous proteins and (ii) gene inactivation by homologous recombination. The reporter gene lacZ, encoding beta-galactosidase, and the gene encoding spiralin, an abundant surface lipoprotein of the related mollicute Spiroplasma citri, were successfully expressed. Functional Escherichia coli beta-galactosidase was detected in transformed Mycoplasma capricolum subsp. capricolum cells despite noticeable codon usage differences. The expression of spiralin in M. capricolum subsp. capricolum was assessed by colony and Western blotting. Accessibility of this protein at the cell surface and its partition into the Triton X-114 detergent phase suggest a correct maturation of the spiralin precursor. The expression of a heterologous lipoprotein in a mycoplasma raises potentially interesting applications, e.g., the use of these bacteria as live vaccines. Targeted inactivation of gene lppA encoding lipoprotein A was achieved in M. capricolum subsp. capricolum with plasmids harboring a replication origin derived from S. citri. Our results suggest that the selection of the infrequent events of homologous recombination could be enhanced by the use of oriC plasmids derived from related mollicute species. Mycoplasma gene inactivation opens the way to functional genomics in a group of bacteria for which a large wealth of genome data are already available and steadily growing. (+info)Distinctive repertoire of contingency genes conferring mutation- based phase variation and combinatorial expression of surface lipoproteins in Mycoplasma capricolum subsp. capricolum of the Mycoplasma mycoides phylogenetic cluster. (3/15)
The generation of surface variation among many divergent species of Mollicutes (mycoplasmas) occurs through stochastic expression patterns of diverse lipoprotein genes. The size and wide distribution of such variable gene sets in minimal (approximately 0.6- to 1.4-Mb) mycoplasmal genomes suggest their key role in the adaptation and survival of these wall-less monoderms. Diversity through variable genes is less clearly established among phylogenetically similar mycoplasmas, such as the Mycoplasma mycoides cluster of ruminant pathogens, which vary widely in host range and pathobiology. Using (i) genome sequences from two members of this clade, Mycoplasma capricolum subsp. capricolum and M. mycoides subsp. mycoides small colony biotype (SC), (ii) antibodies to specific peptide determinants of predicted M. capricolum subsp. capricolum gene products, and (iii) analysis of the membrane-associated proteome of M. capricolum subsp. capricolum, a novel set of six genes (vmcA to vmcF) expressing distinct Vmc (variable M. capricolum subsp. capricolum) lipoproteins is demonstrated. These occur at two separate loci in the M. capricolum subsp. capricolum genome, which shares striking overall similarity and gene synteny with the M. mycoides subsp. mycoides SC genome. Collectively, Vmc expression is noncoordinate and combinatorial, subject to a single-unit insertion/deletion in a 5' flanking dinucleotide repeat that governs expression of each vmc gene. All vmc genes share modular regions affecting expression and membrane translocation. In contrast, vmcA to vmcD genes at one locus express surface proteins with highly structured size-variable repeating domains, whereas vmcE to vmcF genes express products with short repeats devoid of predicted structure. These genes confer a distinctive, dynamic surface architecture that may represent adaptive differences within this important group of pathogens as well as exploitable diagnostic targets. (+info)Flow cytometric determination of the effects of antibacterial agents on Mycoplasma agalactiae, Mycoplasma putrefaciens, Mycoplasma capricolum subsp. capricolum, and Mycoplasma mycoides subsp. mycoides large colony type. (4/15)
Flow cytometry together with SYBR green I and propidium iodide was used to study the effects of enrofloxacin, ciprofloxacin, gentamicin, chloramphenicol, oxytetracycline, and tylosin on four mycoplasma species. Inhibition of mycoplasma growth could be detected by as early as 3 h after the start of treatment. The strongest effect was observed with enrofloxacin- and ciprofloxacin-treated cells. (+info)Development of amber suppressor tRNAs appropriate for incorporation of nonnatural amino acids. (5/15)
An amber suppression method has been used for incorporation of nonnatural amino acids into proteins. However, the incorporation efficiency of nonnatural amino acids through an amber codon has been low, which restricts the application of the proteins containing nonnatural amino acids. In this study, we screened a wide variety of amber suppressor tRNAs to discover tRNAs capable to incorporate nonnatural amino acids with high efficiency. To this purpose, synthetic amber suppressor tRNAs of E. coli and Mycoplasma capricolum were screened for the incorporation of a fluorescently labeled nonnatural amino acid in an E. coli cell-free translation system. tRNAs that showed high capability for the incorporation were then mutated not to be aminoacylated by any of endogenous aminoacyl-tRNA synthetases of E. coli and to enhance the incorporation capability. As a result of these investigations, we successfully obtained several amber suppressor tRNAs with high ability for the incorporation of nonnatural amino acids. (+info)Evolving genetic code. (6/15)
In 1985, we reported that a bacterium, Mycoplasma capricolum, used a deviant genetic code, namely UGA, a "universal" stop codon, was read as tryptophan. This finding, together with the deviant nuclear genetic codes in not a few organisms and a number of mitochondria, shows that the genetic code is not universal, and is in a state of evolution. To account for the changes in codon meanings, we proposed the codon capture theory stating that all the code changes are non-disruptive without accompanied changes of amino acid sequences of proteins. Supporting evidence for the theory is presented in this review. A possible evolutionary process from the ancient to the present-day genetic code is also discussed.

(+info)"Mycoplasma capricolum" is a species of bacteria that belongs to the class Mollicutes and the genus Mycoplasma. These bacteria are characterized by their small size, lack of a cell wall, and unique mode of reproduction through budding or binary fission. "Mycoplasma capricolum" is a common pathogen in goats and sheep, causing various respiratory and mammary gland infections. It can also be found in the genital tract of these animals and can cause reproductive disorders.
The bacteria are typically transmitted through direct contact between infected and non-infected animals, as well as through contaminated feed and water. Infection with "Mycoplasma capricolum" can result in a range of clinical signs, including coughing, nasal discharge, difficulty breathing, decreased milk production, and abortion.
Diagnosis of "Mycoplasma capricolum" infection typically involves the detection of the bacteria in samples taken from the affected animal, such as respiratory secretions or milk. Treatment usually involves the use of antibiotics, although resistance to certain antibiotics has been reported. Prevention and control measures include good biosecurity practices, such as quarantine and testing of new animals before introducing them into a herd, as well as vaccination.
Mycoplasma: A type of bacteria that lack a cell wall and are among the smallest organisms capable of self-replication. They can cause various infections in humans, animals, and plants. In humans, they are associated with respiratory tract infections (such as pneumonia), urogenital infections (like pelvic inflammatory disease), and some sexually transmitted diseases. Mycoplasma species are also known to contaminate cell cultures and can interfere with research experiments. Due to their small size and lack of a cell wall, they are resistant to many common antibiotics, making them difficult to treat.
Contagious pleuropneumonia is a severe, highly contagious respiratory disease primarily affecting small ruminants such as sheep and goats. The causative agent is a gram-negative bacterium called Mycoplasma capricolum subsp. capripneumoniae (Mccp). This disease is predominantly found in Africa, the Middle East, and Asia, although it has the potential to spread rapidly and cause significant economic losses in susceptible populations.
The infection typically causes inflammation of the lungs (pneumonia) and the pleura (pleurisy), which are the membranes lining the thoracic cavity and covering the lungs. Clinical signs include high fever, difficulty breathing, coughing, nasal discharge, loss of appetite, and depression. In severe cases, contagious pleuropneumonia can lead to sudden death due to acute lung failure or complications arising from secondary infections.
Transmission occurs through direct contact with infected animals, contaminated feed, water, or fomites (inanimate objects). The disease is not typically zoonotic, meaning it does not transmit from animals to humans. However, proper biosecurity measures and vaccination programs are crucial to controlling and preventing outbreaks in susceptible herds.
"Mycoplasma mycoides" is a species of bacteria that lack a cell wall and are characterized by their small size. They are part of the class Mollicutes and are known to cause various diseases in animals, particularly ruminants such as cattle, goats, and sheep. The most well-known disease caused by M. mycoides is contagious bovine pleuropneumonia (CBPP), a severe and highly contagious respiratory disease in cattle that can lead to pneumonia, pleurisy, and death.
M. mycoides has been the subject of scientific research due to its small genome size and minimal genetic requirements for growth and survival. In fact, it was the first species of Mycoplasma to have its genome fully sequenced, and it has been used as a model organism in synthetic biology studies.
It's important to note that M. mycoides is not known to cause disease in humans. However, other species of Mycoplasma can cause respiratory and urogenital infections in humans.
Mycoplasma infections refer to illnesses caused by bacteria belonging to the genus Mycoplasma. These are among the smallest free-living organisms, lacking a cell wall and possessing a unique molecular structure. They can cause various respiratory tract infections (like pneumonia, bronchitis), urogenital infections, and other systemic diseases in humans, animals, and birds.
The most common Mycoplasma species that infect humans include M. pneumoniae, M. genitalium, M. hominis, and Ureaplasma urealyticum. Transmission usually occurs through respiratory droplets or sexual contact. Symptoms can vary widely depending on the site of infection but may include cough, chest pain, difficulty breathing, fatigue, joint pain, rash, and genital discharge or pelvic pain in women. Diagnosis often requires specific laboratory tests due to their unique growth requirements and resistance to many common antibiotics. Treatment typically involves macrolide or fluoroquinolone antibiotics.
I believe there may be a misunderstanding in your question. "Goat diseases" refers to illnesses that affect goats specifically. It does not mean diseases that are caused by goats or related to them in some way. Here are some examples of goat diseases:
1. Caprine Arthritis Encephalitis (CAE): A viral disease that affects goats, causing arthritis, pneumonia, and sometimes encephalitis.
2. Caseous Lymphadenitis (CL): A bacterial disease that causes abscesses in the lymph nodes of goats.
3. Contagious Caprine Pleuropneumonia (CCPP): A contagious respiratory disease caused by mycoplasma bacteria.
4. Johne's Disease: A chronic wasting disease caused by a type of bacterium called Mycobacterium avium subspecies paratuberculosis.
5. Pasteurellosis: A bacterial disease that can cause pneumonia, septicemia, and other infections in goats.
6. Salmonellosis: A bacterial disease caused by Salmonella bacteria, which can cause diarrhea, fever, and septicemia in goats.
7. Soremouth (Orf): A viral disease that causes sores and scabs around the mouth and nose of goats.
These are just a few examples of diseases that can affect goats. If you have any specific questions about goat health or diseases, I would recommend consulting with a veterinarian who specializes in small ruminants.
Acholeplasma is a genus of bacteria that are characterized by their lack of a cell wall and their ability to grow in the absence of cholesterol, which is required for the growth of related genera such as Mycoplasma. These organisms are commonly found in various environments, including water, soil, and animals, and can cause opportunistic infections in humans and other animals.
Acholeplasma species are small, pleomorphic bacteria that lack a cell wall and therefore do not stain with Gram's stain. They are typically spherical or coccoid in shape, but can also appear as rods or filaments. These organisms are resistant to many antibiotics due to their lack of a cell wall and the absence of a peptidoglycan layer.
In humans, Acholeplasma species have been associated with respiratory tract infections, urinary tract infections, and bloodstream infections, particularly in immunocompromised individuals. However, these organisms are often considered to be commensals or colonizers rather than true pathogens, as they can also be found in healthy individuals without causing any symptoms.
Overall, Acholeplasma species are important bacteria that can cause opportunistic infections in humans and other animals, but their role in health and disease is still not fully understood.
I'm sorry for any confusion, but "goats" is not a term commonly used in medical definitions. It is a common noun referring to the domesticated animal species Capra aegagrus hircus. If you have any questions about a specific medical condition or term, please provide that and I would be happy to help.
*Acholeplasma laidlawii* is a species of bacteria that belongs to the class Mollicutes. It is a wall-less, pleomorphic organism that can exist in various shapes such as coccoid, rod-like, or filamentous. This bacterium is commonly found in the environment, including water, soil, and plants, and can also be part of the normal microbiota of animals, including humans.
*Acholeplasma laidlawii* is an obligate parasite, meaning it requires a host to survive and reproduce. It is typically associated with causing opportunistic infections in immunocompromised individuals or as a contaminant in laboratory settings. This bacterium can be difficult to culture and identify due to its small size and lack of a cell wall.
It's worth noting that *Acholeplasma laidlawii* is not considered a significant human pathogen, and infections caused by this organism are rare and usually mild. However, it has been used as a model organism in various research studies, including those investigating the mechanisms of bacterial cell division, membrane composition, and interactions with host cells.
Pleuropneumonia is a medical condition characterized by inflammation that affects both the lung tissue (pneumonia) and the pleural space (pleurisy) surrounding the lungs. It is often caused by bacterial infections, such as Streptococcus pneumoniae or Haemophilus influenzae, that spread from the lungs to the pleural space.
The inflammation can cause symptoms such as chest pain, cough, fever, and difficulty breathing. In severe cases, it may lead to complications such as pleural effusion (accumulation of fluid in the pleural space), lung abscesses, or empyema (pus in the pleural space).
Pleuropneumonia can be diagnosed through physical examination, medical history, imaging studies such as chest X-rays or CT scans, and laboratory tests such as blood cultures or analysis of sputum or pleural fluid. Treatment typically involves antibiotics to eliminate the infection, along with supportive care such as pain management, hydration, and respiratory support if necessary.
Mycoplasma hominis is a species of bacteria that lack a cell wall and are among the smallest free-living organisms. They are commonly found as part of the normal flora in the genitourinary tract of humans, particularly in the urethra, cervix, and vagina. However, they can also cause various infections, especially in individuals with compromised immune systems or in the presence of other risk factors.
M. hominis has been associated with several types of infections, including:
1. Genital tract infections: M. hominis can cause pelvic inflammatory disease (PID), cervicitis, urethritis, and endometritis in women. In men, it may lead to urethritis and prostatitis.
2. Postpartum and post-abortion fever: M. hominis can contribute to febrile morbidity following delivery or abortion.
3. Respiratory tract infections: While rare, M. hominis has been implicated in some cases of respiratory tract infections, particularly in immunocompromised individuals.
4. Joint and soft tissue infections: M. hominis can cause septic arthritis, osteomyelitis, and other soft tissue infections, especially in patients with underlying joint diseases or compromised immune systems.
5. Central nervous system (CNS) infections: Although uncommon, M. hominis has been associated with CNS infections such as meningitis and brain abscesses, primarily in immunocompromised individuals.
6. Bloodstream infections: Bacteremia due to M. hominis is rare but can occur in immunocompromised patients or those with indwelling catheters.
Diagnosis of M. hominis infections typically involves the detection of the organism through various laboratory methods, such as culture, polymerase chain reaction (PCR), or serological tests. Treatment usually consists of antibiotics that target mycoplasmas, such as macrolides (e.g., azithromycin) or tetracyclines (e.g., doxycycline). However, resistance to certain antibiotics has been reported in some M. hominis strains.
Mycoplasma genitalium is a small, bacteria that lack a cell wall and can be found in the urinary and genital tracts of humans. It's known to cause several urogenital infections, such as urethritis in men and cervicitis in women. In some cases, it may also lead to pelvic inflammatory disease (PID) and complications like infertility or ectopic pregnancy in women. Mycoplasma genitalium can be sexually transmitted and is often associated with HIV transmission. Due to its small size and atypical growth requirements, it can be challenging to culture and diagnose using standard microbiological methods. Molecular tests, such as nucleic acid amplification tests (NAATs), are commonly used for detection in clinical settings.
Bacterial DNA refers to the genetic material found in bacteria. It is composed of a double-stranded helix containing four nucleotide bases - adenine (A), thymine (T), guanine (G), and cytosine (C) - that are linked together by phosphodiester bonds. The sequence of these bases in the DNA molecule carries the genetic information necessary for the growth, development, and reproduction of bacteria.
Bacterial DNA is circular in most bacterial species, although some have linear chromosomes. In addition to the main chromosome, many bacteria also contain small circular pieces of DNA called plasmids that can carry additional genes and provide resistance to antibiotics or other environmental stressors.
Unlike eukaryotic cells, which have their DNA enclosed within a nucleus, bacterial DNA is present in the cytoplasm of the cell, where it is in direct contact with the cell's metabolic machinery. This allows for rapid gene expression and regulation in response to changing environmental conditions.
"Mycoplasma fermentans" is a type of bacteria that lacks a cell wall and is commonly found as a commensal organism in the human respiratory and urogenital tracts. However, it can also cause opportunistic infections, particularly in individuals with weakened immune systems. It is known to be associated with chronic respiratory infections, inflammatory diseases, and has been suggested as a possible co-factor in the pathogenesis of certain conditions such as rheumatoid arthritis and chronic fatigue syndrome.
The medical definition of "Mycoplasma fermentans" is:
A species of small, gram-negative, pleomorphic bacteria belonging to the genus Mycoplasma, which lacks a cell wall and is capable of causing opportunistic infections in humans. It is commonly found as a commensal organism in the respiratory and urogenital tracts, but has been associated with chronic respiratory infections, inflammatory diseases, and other conditions. Its identification typically requires specialized laboratory tests, such as polymerase chain reaction (PCR) or culture-based methods.
Bacterial RNA refers to the genetic material present in bacteria that is composed of ribonucleic acid (RNA). Unlike higher organisms, bacteria contain a single circular chromosome made up of DNA, along with smaller circular pieces of DNA called plasmids. These bacterial genetic materials contain the information necessary for the growth and reproduction of the organism.
Bacterial RNA can be divided into three main categories: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). mRNA carries genetic information copied from DNA, which is then translated into proteins by the rRNA and tRNA molecules. rRNA is a structural component of the ribosome, where protein synthesis occurs, while tRNA acts as an adapter that brings amino acids to the ribosome during protein synthesis.
Bacterial RNA plays a crucial role in various cellular processes, including gene expression, protein synthesis, and regulation of metabolic pathways. Understanding the structure and function of bacterial RNA is essential for developing new antibiotics and other therapeutic strategies to combat bacterial infections.
"Mycoplasma agalactiae" is a species of bacteria that belongs to the genus Mycoplasma. It is a small, wall-less organism that can cause contagious diseases in animals, particularly in ruminants such as goats and sheep. The infection caused by this bacterium is known as contagious agalactia, which is characterized by symptoms like mastitis (inflammation of the mammary gland), arthritis, keratoconjunctivitis (inflammation of the cornea and conjunctiva of the eye), and sometimes pneumonia. It's worth noting that "Mycoplasma agalactiae" is not known to infect humans.
"Mycoplasma hyopneumoniae" is a type of bacteria that primarily affects the respiratory system of pigs, causing a disease known as Enzootic Pneumonia. It is one of the most common causes of pneumonia in pigs and can lead to reduced growth rates, decreased feed conversion efficiency, and increased mortality in infected herds.
The bacteria lack a cell wall, which makes them resistant to many antibiotics that target cell wall synthesis. They are also highly infectious and can be transmitted through direct contact with infected pigs or contaminated fomites such as feed, water, and equipment. Infection with "Mycoplasma hyopneumoniae" can lead to the development of lesions in the lungs, which can make the animal more susceptible to secondary bacterial and viral infections.
Diagnosis of Mycoplasma hyopneumoniae infection typically involves a combination of clinical signs, laboratory tests such as serology, PCR, or culture, and sometimes histopathological examination of lung tissue. Control measures may include antibiotic treatment, vaccination, biosecurity measures, and herd management practices aimed at reducing the spread of the bacteria within and between pig populations.
A base sequence in the context of molecular biology refers to the specific order of nucleotides in a DNA or RNA molecule. In DNA, these nucleotides are adenine (A), guanine (G), cytosine (C), and thymine (T). In RNA, uracil (U) takes the place of thymine. The base sequence contains genetic information that is transcribed into RNA and ultimately translated into proteins. It is the exact order of these bases that determines the genetic code and thus the function of the DNA or RNA molecule.
"Mycoplasma bovis" is a species of bacteria that lack a cell wall and are characterized by their small size. They can cause various diseases in cattle, including pneumonia, mastitis (inflammation of the mammary gland), arthritis, and otitis (inflammation of the ear). The bacteria can be transmitted through direct contact between animals, contaminated milk, and aerosols. Infection with Mycoplasma bovis can result in decreased productivity and increased mortality in affected herds, making it a significant concern for the cattle industry. Diagnosis is often made through culture or PCR-based tests, and treatment typically involves the use of antibiotics, although resistance to certain antibiotics has been reported. Prevention strategies include biosecurity measures such as testing and culling infected animals, as well as good hygiene practices to limit the spread of the bacteria.
A bacterial gene is a segment of DNA (or RNA in some viruses) that contains the genetic information necessary for the synthesis of a functional bacterial protein or RNA molecule. These genes are responsible for encoding various characteristics and functions of bacteria such as metabolism, reproduction, and resistance to antibiotics. They can be transmitted between bacteria through horizontal gene transfer mechanisms like conjugation, transformation, and transduction. Bacterial genes are often organized into operons, which are clusters of genes that are transcribed together as a single mRNA molecule.
It's important to note that the term "bacterial gene" is used to describe genetic elements found in bacteria, but not all genetic elements in bacteria are considered genes. For example, some DNA sequences may not encode functional products and are therefore not considered genes. Additionally, some bacterial genes may be plasmid-borne or phage-borne, rather than being located on the bacterial chromosome.
A codon is a sequence of three adjacent nucleotides in DNA or RNA that specifies the insertion of a particular amino acid during protein synthesis, or signals the beginning or end of translation. In DNA, these triplets are read during transcription to produce a complementary mRNA molecule, which is then translated into a polypeptide chain during translation. There are 64 possible codons in the standard genetic code, with 61 encoding for specific amino acids and three serving as stop codons that signal the termination of protein synthesis.
Molecular sequence data refers to the specific arrangement of molecules, most commonly nucleotides in DNA or RNA, or amino acids in proteins, that make up a biological macromolecule. This data is generated through laboratory techniques such as sequencing, and provides information about the exact order of the constituent molecules. This data is crucial in various fields of biology, including genetics, evolution, and molecular biology, allowing for comparisons between different organisms, identification of genetic variations, and studies of gene function and regulation.
Bacterial proteins are a type of protein that are produced by bacteria as part of their structural or functional components. These proteins can be involved in various cellular processes, such as metabolism, DNA replication, transcription, and translation. They can also play a role in bacterial pathogenesis, helping the bacteria to evade the host's immune system, acquire nutrients, and multiply within the host.
Bacterial proteins can be classified into different categories based on their function, such as:
1. Enzymes: Proteins that catalyze chemical reactions in the bacterial cell.
2. Structural proteins: Proteins that provide structural support and maintain the shape of the bacterial cell.
3. Signaling proteins: Proteins that help bacteria to communicate with each other and coordinate their behavior.
4. Transport proteins: Proteins that facilitate the movement of molecules across the bacterial cell membrane.
5. Toxins: Proteins that are produced by pathogenic bacteria to damage host cells and promote infection.
6. Surface proteins: Proteins that are located on the surface of the bacterial cell and interact with the environment or host cells.
Understanding the structure and function of bacterial proteins is important for developing new antibiotics, vaccines, and other therapeutic strategies to combat bacterial infections.
"Mycoplasma pulmonis" is a species of bacteria that belongs to the genus Mycoplasma, which are characterized as the smallest free-living organisms. "M. pulmonis" is known to primarily infect rodents, particularly mice and rats, causing respiratory diseases. It colonizes the upper and lower respiratory tract, leading to conditions such as murine respiratory mycoplasmosis (MRM).
The bacteria lack a cell wall, which makes them resistant to many antibiotics that target cell wall synthesis. They can cause chronic inflammation and damage to the respiratory system, including airway obstruction, bronchiolitis, and alveolitis. Transmission of "M. pulmonis" typically occurs through direct contact with infected animals or their aerosolized secretions.
It is important to note that "Mycoplasma pulmonis" does not infect humans and is primarily a research model for studying bacterial respiratory infections and host immune responses.
"Mycoplasma gallisepticum" is a species of bacteria that belongs to the class Mollicutes and the genus Mycoplasma. It is a significant pathogen in birds, particularly in poultry such as chickens and turkeys, causing chronic respiratory disease (CRD) and infectious sinusitis. The bacterium lacks a cell wall, which makes it resistant to many antibiotics that target the cell wall. Mycoplasma gallisepticum can be transmitted through direct contact with infected birds or contaminated equipment and is highly contagious. It can cause significant economic losses in the poultry industry due to decreased growth rates, poor feed conversion, and increased mortality. In addition to poultry, Mycoplasma gallisepticum has also been found to infect wild bird species, such as house finches, leading to population declines in some areas.
Species specificity is a term used in the field of biology, including medicine, to refer to the characteristic of a biological entity (such as a virus, bacterium, or other microorganism) that allows it to interact exclusively or preferentially with a particular species. This means that the biological entity has a strong affinity for, or is only able to infect, a specific host species.
For example, HIV is specifically adapted to infect human cells and does not typically infect other animal species. Similarly, some bacterial toxins are species-specific and can only affect certain types of animals or humans. This concept is important in understanding the transmission dynamics and host range of various pathogens, as well as in developing targeted therapies and vaccines.
Mycoplasma penetrans is a species of bacteria that lack a cell wall and are therefore resistant to many antibiotics that target the cell wall. It is a sexually transmitted infection (STI) that can infect the urogenital tract, causing inflammation and damage to the cells lining the urinary and reproductive systems.
M. penetrans has been associated with several health problems, including urethritis (inflammation of the urethra), cervicitis (inflammation of the cervix), pelvic inflammatory disease (PID), and increased risk of HIV transmission. However, its role in these conditions is not fully understood and further research is needed to determine the exact nature of its pathogenicity.
Diagnosis of M. penetrans infection typically involves nucleic acid amplification tests (NAATs) or direct detection of the organism in clinical specimens. Treatment usually involves antibiotics such as macrolides, fluoroquinolones, or tetracyclines, although resistance to these drugs has been reported.
It is important to note that M. penetrans infection can be asymptomatic and may not cause any noticeable symptoms in some people. Therefore, it is recommended to practice safe sex and get regular STI screenings to detect and treat infections early.
Mycoplasma synoviae is a species of bacteria that lack a cell wall and can cause chronic respiratory infections and inflammation of the synovial membranes (synovitis) in birds, particularly in poultry such as chickens and turkeys. The infection can lead to decreased growth rate, reduced egg production, and lameness in affected birds. Mycoplasma synoviae is transmitted horizontally through direct contact with infected birds or contaminated equipment and vertically from infected hens to their offspring. It is important to note that Mycoplasma synoviae is not known to cause disease in humans.
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.
"Mycoplasma hyorhinis" is a species of bacteria belonging to the genus Mycoplasma, which are characterized as the smallest free-living organisms. They lack a cell wall and have a unique cell membrane structure. "Mycoplasma hyorhinis" specifically infects pigs, causing respiratory infections and polyserositis (inflammation of the serous membranes lining the thoracic and abdominal cavities). It can also be found as a commensal organism in the upper respiratory tract. In recent years, it has been identified as a potential low-grade pathogen in humans, associated with certain types of cancer and joint inflammation, although its exact role in these conditions remains unclear.
Mycoplasma arthritidis is not a recognized medical term or a specific disease entity in humans. Mycoplasmas are a type of bacteria that lack a cell wall and can cause various infections in humans and animals. However, Mycoplasma arthritidis is a strain that has been primarily studied in animal models, particularly in mice, where it can cause joint inflammation (arthritis).
In mice, Mycoplasma arthritidis infection can lead to a severe and chronic form of arthritis. The bacteria colonize the synovial membrane, which lines the joint cavity, and induce an immune response that results in inflammation and tissue damage. This model has been used to study the pathogenesis of arthritis and potential therapeutic interventions.
However, it is important to note that Mycoplasma arthritidis is not known to cause disease in humans, and its relevance to human health is limited to the insights it provides into the basic mechanisms of bacterial infection and joint inflammation.
