Single channel analysis of recombinant major outer membrane protein porins from Chlamydia psittaci and Chlamydia pneumoniae. (1/396)
We recently demonstrated that the major outer membrane protein of Chlamydia psittaci, the primary vaccine candidate for combating chlamydial infections, functions as a porin-like ion channel. In this study, we have cloned, expressed and functionally reconstituted recombinant major outer membrane proteins from C. psittaci and Chlamydia pneumoniae and analysed them at the single channel level. Both form porin-like ion channels that are functionally similar to those formed by native C. psittaci major outer membrane protein. Also, like the native channels, recombinant C. psittaci channels are modified by a native major outer membrane protein-specific monoclonal antibody. This is the first time that native function has been demonstrated for recombinant chlamydial major outer membrane proteins. Future bilayer reconstitution will provide a strategy for detailed structure/function studies of this new subclass of bacterial porins and the work also has important implications for successful protein refolding and the development of improved subunit vaccines. (+info)Role of polymorphonuclear neutrophils in a murine model of Chlamydia psittaci-induced abortion. (2/396)
To assess the role of polymorphonuclear neutrophils (PMNs) in Chlamydia psittaci infection in a pregnant mouse model, pregnant and nonpregnant Swiss OF1 mice were depleted of PMNs by treatment with the RB6-8C5 monoclonal antibody before intraperitoneal infection with C. psittaci serotype 1. Nondepleted mice served as infection controls. Depleted mice aborted earlier and had a much higher mortality rate than nondepleted mice. Bacteriological analysis showed that the number of chlamydiae isolated from the spleens of depleted mice at 5 and 7 days postinfection was 100 times greater than that isolated from nondepleted mice. Histopathological analysis of the placentas of depleted mice showed widespread necrosis of the uteroplacental units, with weak immunoreaction to chlamydial antigen, while the placentas of nondepleted mice showed substantial neutrophil infiltration but no large areas of necrosis, with moderate to strong immunoreaction to chlamydial antigen. The livers of depleted mice showed numerous chlamydial inclusions in the hepatocytes, delayed microgranuloma formation, and in the pregnant animals extensive coagulative periportal necrosis. The livers of nondepleted mice displayed multiple small foci of PMNs and mononuclear cells with microgranuloma formation. Among this group of mice, the pregnant animals always had more hepatic damage than nonpregnant animals. Our results suggest that PMNs play an essential role in the response to C. psittaci primary infection, preventing the uncontrolled multiplication of chlamydiae in the liver and spleen. (+info)The species specificity of the microimmunofluorescence antibody test and comparisons with a time resolved fluoroscopic immunoassay for measuring IgG antibodies against Chlamydia pneumoniae. (3/396)
AIMS: To examine the species specificity of the microimmunofluorescence test (MIF) and assess a time resolved fluoroscopic immunoassay (TRIA) for measuring IgG antibodies to C pneumoniae. METHODS: Sera from 1020 subjects were tested by MIF for IgG, IgM, and IgA antibodies to C pneumoniae, C trachomatis, and C psittaci; 501 serum samples were also tested by TRIA for IgG antibodies to C pneumoniae. RESULTS: C pneumoniae antibody titres as measured by MIF were correlated with those for C psittaci and trachomatis. It was estimated that on average, one third of the twofold dilution steps that make up the final C pneumoniae antibody titre may be due to cross reacting genus specific antibody. The results of TRIA correlated well with those of MIF. In 75% of cases, the TRIA result predicted a three titre range within which the actual MIF result would fall. CONCLUSIONS: MIF does not appear to be as species specific as claimed. TRIA is unlikely to be as specific but as it is completely objective, easier to perform, amenable to automation, and gives reproducible results, it is a rapid and useful method for comparing populations. (+info)Comparative in-vitro activity of moxifloxacin, minocycline and azithromycin against Chlamydia spp. (4/396)
The in-vitro activity of moxifloxacin, a new 8-methoxyquinolone, was compared with minocycline and azithromycin against 40 strains of Chlamydia trachomatis, Chlamydia pneumoniae and Chlamydia psittaci. Both the MIC and the MBC of moxifloxacin ranged from 0.03 to 0.125 mg/L. MICs of minocycline ranged from 0.015 to 0.06 mg/L and MBCs between 0.03 and 0.25 mg/L. MICs of azithromycin ranged from 0.03 to 0.125 mg/L and the MBCs between 0.06 and 0.5 mg/L. MBC values of moxifloxacin were the same as MICs in 32 (80%) of 40 strains tested, whereas those of minocycline and azithromycin were two to four times higher than their MICs. These data confirm those previously obtained indicating that quinolones kill chlamydial strains at concentrations equivalent to their MICs. (+info)Genomic relatedness of Chlamydia isolates determined by amplified fragment length polymorphism analysis. (5/396)
The genomic relatedness of 19 Chlamydia pneumoniae isolates (17 from respiratory origin and 2 from atherosclerotic origin), 21 Chlamydia trachomatis isolates (all serovars from the human biovar, an isolate from the mouse biovar, and a porcine isolate), 6 Chlamydia psittaci isolates (5 avian isolates and 1 feline isolate), and 1 Chlamydia pecorum isolate was studied by analyzing genomic amplified fragment length polymorphism (AFLP) fingerprints. The AFLP procedure was adapted from a previously developed method for characterization of clinical C. trachomatis isolates. The fingerprints of all C. pneumoniae isolates were nearly identical, clustering together at a Dice similarity of 92.6% (+/- 1.6% standard deviation). The fingerprints of the C. trachomatis isolates of human, mouse, and swine origin were clearly distinct from each other. The fingerprints of the isolates from the human biovar could be divided into at least 12 different types when the presence or absence of specific bands was taken into account. The C. psittaci fingerprints could be divided into a parakeet, a pigeon, and a feline type. The fingerprint of C. pecorum was clearly distinct from all others. Cluster analysis of selected isolates from all species revealed groups other than those based on sequence data from single genes (in particular, omp1 and rRNA genes) but was in agreement with available DNA-DNA hybridization data. In conclusion, cluster analysis of AFLP fingerprints of representatives of all species provided suggestions for a grouping of chlamydiae based on the analysis of the whole genome. Furthermore, genomic AFLP analysis showed that the genome of C. pneumoniae is highly conserved and that no differences exist between isolates of respiratory and atherosclerotic origins. (+info)Cytokine release by ovine macrophages following infection with Chlamydia psittaci. (6/396)
Chlamydia psittaci is an obligate intracellular pathogen that causes abortion in both sheep and humans. The disease in sheep (but not humans) is characterized by a long-term persistent phase that appears to be under the control of interferon-gamma. However, nothing is known about cytokine induction that precedes the persistent phase in sheep. Primary alveolar lavage cells recovered from normal adult sheep were used to study cytokine production in the first 72 h of infection with C. psittaci. These cells were phenotypically characteristic of macrophages, being adherent, phagocytic, CD14+ and staining positive for non-specific esterase. In vitro infection of the macrophages with C. psittaci resulted in the release of IL-1beta, IL-8 and granulocyte-macrophage colony-stimulating factor (GM-CSF) as measured by ovine-specific ELISAs. Heat-treated chlamydiae (1 h at 65 degrees C) did not induce the release of IL-1beta, but the release of IL-8 was similar to that induced by untreated organisms. The cells from different sheep varied most notably in their patterns of GM-CSF release in response to heat-treated and untreated organisms. (+info)Multiplex polymerase chain reaction for the simultaneous detection of Mycoplasma pneumoniae, Chlamydia pneumoniae, and Chlamydia psittaci in respiratory samples. (7/396)
AIMS: To develop a multiplex polymerase chain reaction (PCR) for the simultaneous detection of Mycoplasma pneumoniae, Chlamydia pneumoniae, and Chlamydia psittaci in respiratory samples. METHODS: Oligonucleotide primers for the amplification of the DNA of these three organisms were optimised for use in combination in the same reaction. PCR products were detected by hybridisation with pooled internal probes using an enzyme linked immunosorbent assay. Those with positive signals were further differentiated using species specific probes. Quality of DNA extraction and PCR inhibition were controlled by amplification of a human mitochondrial gene. A panel of 53 respiratory samples with known results was evaluated blindly. This was followed by a retrospective study on sputa collected from 244 patients with suspected community acquired pneumonia. RESULTS: The multiplex assay had a lower sensitivity than PCR with individual primers by about one log. The resultant sensitivity was considered acceptable for diagnostic use. Of the panel of 53 samples, nine of 11 M pneumoniae, 11 of 11 C pneumoniae, six of seven C psittaci, and 24 of 24 negative samples were correctly identified. Of the 244 patients with pneumonia, seven (2.9%) had detectable M pneumoniae, six (2.5%) had C pneumoniae, and one (0.4%) had C psittaci. The case notes from 11 patients were studied. The PCR finding was of possible significance in at least eight of these patients. CONCLUSIONS: This multiplex PCR assay has the potential to be used as a diagnostic and epidemiological tool. Further prospective studies are needed to establish its clinical value. (+info)Significance of host cell kinesin in the development of Chlamydia psittaci. (8/396)
The influence of the microtubule-associated motor protein kinesin on Chlamydia psittaci inclusion development in epithelial and fibroblast cell lines was addressed. Kinesin was blocked early after chlamydial internalization (4 h postinfection [p.i.]) and before the initiation of active chlamydial multiplication (8 h p.i.). Chlamydia development was monitored by fluorescence and transmission electron microscopy at different times during the cycle. In both host cell lines, kinesin blockage restricted mitochondria from the chlamydial vacuole. The effects of kinesin blockage on the C. psittaci replication cycle included the presence of multiple inclusions up to late in the cycle, the presence of enlarged pleomorphic reticulate bodies, and a delayed reappearance of elementary bodies. The last effect seems to be greater when kinesin is blocked early after infection. Our results show that kinesin activity is required for optimal development of these microorganisms, most probably acting through the apposition of mitochondria to the C. psittaci inclusions. (+info)Psittacosis is a zoonotic disease caused by the bacterium Chlamydia psittaci. It is primarily transmitted to humans through inhalation of respiratory droplets from infected birds, particularly parrots and parakeets. The disease can also be transmitted through direct contact with infected birds or their feces, as well as through contaminated objects or surfaces. Symptoms of psittacosis can vary depending on the severity of the infection, but may include fever, chills, headache, muscle aches, cough, shortness of breath, and chest pain. In severe cases, the disease can lead to pneumonia, meningitis, and even death. Treatment for psittacosis typically involves the use of antibiotics, such as doxycycline or azithromycin. Prevention measures include avoiding contact with infected birds, wearing protective clothing and gloves when handling birds, and thoroughly cleaning and disinfecting any objects or surfaces that may have come into contact with infected birds.
Chlamydophila infections are a group of bacterial infections caused by the Chlamydiae family of bacteria. These infections can affect various parts of the body, including the respiratory tract, eyes, and genitals. Chlamydophila pneumoniae is a common cause of atypical pneumonia, which is a type of pneumonia that does not respond to typical antibiotics. It can also cause bronchitis, sinusitis, and other respiratory infections. Chlamydia trachomatis is a sexually transmitted infection that can cause infections of the cervix, uterus, fallopian tubes, and eyes. It is the most common cause of sexually transmitted infections in the United States. Chlamydia psittaci is a zoonotic infection that can be transmitted to humans through contact with infected birds or their droppings. It can cause respiratory infections, including pneumonia and bronchitis. Chlamydia suis is a zoonotic infection that can be transmitted to humans through contact with infected pigs or their products. It can cause respiratory infections, including pneumonia and bronchitis. Chlamydia abortus is a zoonotic infection that can be transmitted to humans through contact with infected cattle or their products. It can cause respiratory infections, including pneumonia and bronchitis. Chlamydia pneumoniae and Chlamydia trachomatis are the most common Chlamydophila infections in humans. They are typically treated with antibiotics, although some strains of Chlamydia trachomatis have become resistant to certain antibiotics.
Bird diseases refer to any illness or infection that affects birds, including domesticated birds such as chickens, turkeys, and ducks, as well as wild birds. These diseases can be caused by a variety of factors, including viruses, bacteria, fungi, parasites, and environmental factors such as exposure to toxins or pollutants. Bird diseases can range in severity from mild to life-threatening, and can affect birds of all ages and species. Some common bird diseases include avian influenza, Newcastle disease, fowl pox, Marek's disease, and psittacosis. In the medical field, bird diseases are typically diagnosed and treated by veterinarians who specialize in avian medicine. Treatment may involve medications, vaccines, or other interventions to manage symptoms and prevent the spread of the disease. In some cases, birds may need to be euthanized if the disease is too severe or if treatment is not effective.
Zoonoses are infectious diseases that are transmitted from animals to humans. These diseases can be caused by bacteria, viruses, parasites, or fungi, and can be transmitted through direct contact with animals, their bodily fluids, or their feces, or through the bites of infected insects or ticks. Examples of zoonoses include rabies, Lyme disease, brucellosis, and salmonellosis. Zoonoses can be a significant public health concern, as they can spread rapidly and cause serious illness or even death in humans. They can also have a significant economic impact, as they can affect livestock and wildlife populations, and can lead to the closure of farms or the destruction of animals to prevent the spread of disease.
In the medical field, "Abortion, Veterinary" refers to the intentional termination of a pregnancy in an animal. This can be done for various reasons, such as to prevent the birth of unhealthy or unwanted offspring, to treat certain medical conditions in the animal, or to manage the reproductive health of the animal. There are different methods of veterinary abortion, including surgical procedures and medical treatments. The specific method used depends on the stage of pregnancy, the health of the animal, and the reason for the abortion. It is important to note that veterinary abortions are typically performed by veterinarians who are trained and licensed to do so, and are subject to strict regulations and guidelines to ensure the safety and well-being of the animal.
Poultry diseases refer to any illness or infection that affects birds that are raised for meat, eggs, or other products. These diseases can be caused by a variety of factors, including bacteria, viruses, fungi, parasites, and environmental conditions. Some common poultry diseases include avian influenza, Newcastle disease, fowl pox, coccidiosis, and salmonellosis. These diseases can have significant economic impacts on the poultry industry, as well as pose a risk to human health if the birds are consumed or the disease is transmitted to other animals or humans. Treatment and prevention strategies for poultry diseases include vaccination, proper sanitation and hygiene practices, and the use of antibiotics or other medications as needed.
Bacterial outer membrane proteins (OMPs) are proteins that are located on the outer surface of the cell membrane of bacteria. They play important roles in the survival and pathogenicity of bacteria, as well as in their interactions with the environment and host cells. OMPs can be classified into several categories based on their function, including porins, which allow the passage of small molecules and ions across the outer membrane, and lipoproteins, which are anchored to the outer membrane by a lipid moiety. Other types of OMPs include adhesins, which mediate the attachment of bacteria to host cells or surfaces, and toxins, which can cause damage to host cells. OMPs are important targets for the development of new antibiotics and other antimicrobial agents, as they are often essential for bacterial survival and can be differentially expressed by different bacterial strains or species. They are also the subject of ongoing research in the fields of microbiology, immunology, and infectious diseases.
DNA, Bacterial refers to the genetic material of bacteria, which is a type of single-celled microorganism that can be found in various environments, including soil, water, and the human body. Bacterial DNA is typically circular in shape and contains genes that encode for the proteins necessary for the bacteria to survive and reproduce. In the medical field, bacterial DNA is often studied as a means of identifying and diagnosing bacterial infections. Bacterial DNA can be extracted from samples such as blood, urine, or sputum and analyzed using techniques such as polymerase chain reaction (PCR) or DNA sequencing. This information can be used to identify the specific type of bacteria causing an infection and to determine the most effective treatment. Bacterial DNA can also be used in research to study the evolution and diversity of bacteria, as well as their interactions with other organisms and the environment. Additionally, bacterial DNA can be modified or manipulated to create genetically engineered bacteria with specific properties, such as the ability to produce certain drugs or to degrade pollutants.
Chlamydiaceae infections refer to a group of bacterial infections caused by members of the family Chlamydiaceae. These bacteria are obligate intracellular parasites, meaning they require a host cell to survive and replicate. Chlamydiaceae infections can affect a wide range of hosts, including humans, animals, and plants. In humans, Chlamydiaceae infections can cause a variety of diseases, including sexually transmitted infections (STIs) such as chlamydia and trichomoniasis, as well as respiratory infections such as pneumonia and bronchitis. These infections can be asymptomatic or cause mild to severe symptoms, depending on the type and severity of the infection. Chlamydiaceae infections are typically diagnosed through laboratory testing, such as nucleic acid amplification tests (NAATs) or culture. Treatment typically involves antibiotics, although some strains of chlamydia have become resistant to certain antibiotics. Prevention measures include practicing safe sex, avoiding close contact with infected individuals, and getting vaccinated against certain types of chlamydia.
In the medical field, "Sheep Diseases" refers to a group of illnesses and infections that affect sheep, which are domesticated ruminant mammals. These diseases can be caused by various agents, including bacteria, viruses, fungi, and parasites. Some common sheep diseases include: 1. Scrapie: a fatal neurodegenerative disease caused by a prion protein. 2. Bluetongue: a viral disease that affects the mouth and tongue of sheep and other ruminants. 3. Foot-and-mouth disease: a highly contagious viral disease that affects the mouth, feet, and udder of sheep and other cloven-hoofed animals. 4. Pneumonia: a respiratory disease caused by bacteria or viruses that can be fatal in severe cases. 5. Eimeriosis: a parasitic disease caused by coccidia that affects the digestive system of sheep. 6. Johne's disease: a chronic bacterial infection that affects the digestive system of sheep and other ruminants. 7. Coccidiosis: a parasitic disease caused by coccidia that affects the digestive system of sheep. 8. Anthrax: a bacterial disease that can affect the skin, respiratory system, and digestive system of sheep. 9. Leptospirosis: a bacterial disease that can affect the kidneys and liver of sheep. 10. Brucellosis: a bacterial disease that can affect the reproductive system of sheep and other ruminants. Prevention and control of sheep diseases are essential to maintain the health and productivity of sheep populations. This can be achieved through vaccination, proper nutrition, hygiene, and management practices.
Chlamydia infections are a common sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. The infection can affect both men and women and can cause a range of symptoms, including burning during urination, abnormal vaginal discharge, and pain during sexual intercourse. In women, chlamydia can also cause pelvic inflammatory disease (PID), which can lead to serious complications such as infertility and ectopic pregnancy. Chlamydia infections are typically diagnosed through a urine or vaginal swab test. Treatment typically involves antibiotics, which can cure the infection and prevent complications. However, many people with chlamydia do not experience any symptoms and may not know they have the infection, which is why routine testing and treatment are important for preventing the spread of the disease.
Antibodies, Bacterial are proteins produced by the immune system in response to bacterial infections. They are also known as bacterial antibodies or bacterial immunoglobulins. These antibodies are specific to bacterial antigens, which are molecules found on the surface of bacteria that trigger an immune response. When the immune system detects a bacterial infection, it produces antibodies that bind to the bacterial antigens and mark them for destruction by other immune cells. This helps to neutralize the bacteria and prevent them from causing harm to the body. Bacterial antibodies can be detected in the blood or other bodily fluids using laboratory tests. These tests are often used to diagnose bacterial infections and to monitor the effectiveness of antibiotic treatments.
Pneumonia, Mycoplasma is a type of pneumonia caused by the bacterium Mycoplasma pneumoniae. It is a common respiratory infection that affects the lungs and can cause symptoms such as cough, fever, chest pain, and difficulty breathing. Mycoplasma pneumoniae is a small, non-acid-fast bacterium that is difficult to culture and can be difficult to diagnose. It is typically spread through respiratory droplets when an infected person coughs or sneezes. Treatment for Mycoplasma pneumoniae pneumonia usually involves antibiotics, although some cases may not respond to treatment. In severe cases, hospitalization may be necessary.
Conjunctivitis is an inflammation of the conjunctiva, which is the thin, transparent membrane that lines the inside of the eyelids and covers the white part of the eye. It is commonly known as "pink eye" and can be caused by a variety of factors, including bacteria, viruses, allergies, irritants, and certain medications. The symptoms of conjunctivitis can include redness, itching, tearing, sensitivity to light, and discharge from the eyes. The severity and duration of the symptoms can vary depending on the cause of the inflammation. Treatment for conjunctivitis depends on the underlying cause. For bacterial conjunctivitis, antibiotics may be prescribed. For viral conjunctivitis, there is no specific treatment, but the symptoms can be managed with over-the-counter eye drops or ointments. Allergic conjunctivitis can be treated with antihistamines or allergy drops. In some cases, the conjunctivitis may resolve on its own without any treatment. It is important to seek medical attention if you suspect you have conjunctivitis, as it can be contagious and can spread to others, especially if it is caused by a virus.
In the medical field, "Cat Diseases" refers to any illness or condition that affects cats. These diseases can be caused by a variety of factors, including viruses, bacteria, fungi, parasites, genetics, and environmental factors. Some common cat diseases include upper respiratory infections, feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), urinary tract infections, gastrointestinal diseases, skin conditions, and cancer. The diagnosis and treatment of cat diseases typically involve a combination of physical examination, laboratory tests, imaging studies, and medical interventions such as medications, surgery, and supportive care. It is important for cat owners to be aware of the common diseases that affect their pets and to seek veterinary care promptly if their cat shows any signs of illness or discomfort. Regular veterinary check-ups and preventive measures such as vaccinations and parasite control can also help to prevent the development of cat diseases.
