Methicillin-Resistant Staphylococcus aureus
Identification in methicillin-susceptible Staphylococcus hominis of an active primordial mobile genetic element for the staphylococcal cassette chromosome mec of methicillin-resistant Staphylococcus aureus. (1/18)
We previously reported that the methicillin resistance gene mecA is carried by a novel type of mobile genetic element, SCCmec (staphylococcal cassette chromosome mec), in the chromosome of methicillin-resistant Staphylococcus aureus (MRSA). These elements are precisely excised from the chromosome and integrated into a specific site on the recipient chromosome by a pair of recombinase proteins encoded by the cassette chromosome recombinase genes ccrA and ccrB. In the present work, we detected homologues of the ccr genes in Staphylococcus hominis type strain GIFU12263 (equivalent to ATCC 27844), which is susceptible to methicillin. Sequence determination revealed that the ccr homologues in S. hominis were type 1 ccr genes (ccrA1 and ccrB1) that were localized on a genetic element structurally very similar to SCCmec except for the absence of the methicillin-resistance gene, mecA. This genetic element had mosaic-like patterns of homology with extant SCCmec elements, and we designated it SCC(12263) and considered it a type I staphylococcal cassette chromosome (SCC). The ccrB1 gene identified in the S. hominis strain is the first type 1 ccrB gene discovered to retain its function through the excision process as judged by two criteria: (i) SCC(12263) was spontaneously excised during cultivation of the strain and (ii) introduction of the S. hominis ccrB1 into an MRSA strain carrying a type I SCCmec whose ccrB1 gene is inactive generated SCCmec excisants at a high frequency. The existence of an SCC without a mec determinant is indicative of a staphylococcal site-specific mobile genetic element that serves as a vehicle of transfer for various genetic markers between staphylococcal species.

Bacterial infections are frequent in cadaveric organ donors and can be transmitted to the transplantation recipient, which could have devastating consequences for the recipients if adequate preventive measures are not adopted. From the 355 consecutive brain dead cadaveric organ donors procured at our center in the last four years, 2000-2003, four of them (1.1%) had bacterial endocarditis as cause of death. The bacteria responsible for the endocarditis were Staphylococcus epidermidis, coagulase-negative Staphylococcus, Staphylococcus hominis and Streptococcus viridans, respectively. We performed five kidney and two liver transplantations on seven recipients. All donors and recipients received antibiotic treatment against the germ causing the respective endocarditis. Infection by the bacteria responsible for the endocarditis in the respective donors was not transmitted to any of the recipients. Six of the seven recipients were alive with normal-functioning grafts after between 13 and 24 months' follow-up. Transplantectomy was performed on one kidney recipient due to thrombosis of the renal vein of the graft not related to the endocarditis. Liver and kidney transplantation from donors dying from bacterial endocarditis can be performed without causing the transmission of infection to the recipient or the dysfunction of the graft.

From 2002 to 2003, 32 isolates of Staphylococcus hominis subsp. novobiosepticus (SHN) were recovered from 21 patients, 18 of whom were neonates, with 13 considered to have late-onset SHN sepsis. All isolates from neonates had an indistinguishable pulsed-field gel electrophoresis pattern. Our data support SHN as an important nosocomial pathogen in neonates.

Structural and genetic analysis indicated that the bacteriocin is a variant of nukacin ISK-1, a type-A(II) lantibiotic, and we termed the bacteriocin nukacin KQU-131. There were three different amino acid residues between nukacin ISK-1 and nukacin KQU-131, one residue in the leader peptide and the other two in the mature peptide.

(+info)Resistance of bacterial biofilms formed on stainless steel surface to disinfecting agent. (8/18)
The natural ability of microorganisms for adhesion and biofilm formation on various surfaces is one of the factors causing the inefficiency of a disinfection agent, despite its proven activity in vitro. The aim of the study was to determine the effectiveness of disinfecting substances on bacterial biofilms formed on stainless steel surface. A universally applied disinfecting agent was used in the tests. Bacterial strains: Listeria innocua, Pseudomonas putida, Micrococcus luteus, Staphylococcus hominis strains, were isolated from food contact surfaces, after a cleaning and disinfection process. The disinfecting agent was a commercially available acid specimen based on hydrogen peroxide and peroxyacetic acid, the substance that was designed for food industry usage. Model tests were carried out on biofilm formed on stainless steel (type 304, no 4 finish). Biofilms were recorded by electron scanning microscope. The disinfecting agent in usable concentration, 0.5% and during 10 minutes was ineffective for biofilms. The reduction of cells in biofilms was only 1-2 logarithmic cycles. The use of the agent in higher concentration--1% for 30 minutes caused reduction of cell number by around 5 logarithmic cycles only in the case of one microorganism, M. luteus. For other types: L. innocua, P. putida, S. hominis, the requirements placed on disinfecting agents were not fulfilled. The results of experiments proved that bacterial biofilms are resistant to the disinfectant applied in its operational parameters. Disinfecting effectiveness was achieved after twofold increase of the agent's concentration. (+info)"Staphylococcus hominis" is a species of grampositive, facultatively anaerobic bacteria that belongs to the genus Staphylococcus. It is commonly found on the skin and mucous membranes of humans, particularly in the nostrils and groin area. While it is generally considered to be a commensal organism, meaning that it can exist harmlessly on the body without causing disease, S. hominis has been associated with some types of infections, such as bloodstream infections (bacteremia) and device-related infections (such as catheter-associated infections). However, these infections are relatively rare compared to those caused by other Staphylococcus species like S. aureus.
It's worth noting that while S. hominis is a normal part of the human microbiome, it can sometimes cause infections if it enters the body through a break in the skin or if it colonizes medical devices such as catheters. In these cases, it may be necessary to treat the infection with antibiotics. However, because S. hominis is resistant to many commonly used antibiotics, identifying the specific species of bacteria causing an infection can help guide appropriate treatment decisions.
Staphylococcus is a genus of Gram-positive, facultatively anaerobic bacteria that are commonly found on the skin and mucous membranes of humans and other animals. Many species of Staphylococcus can cause infections in humans, but the most notable is Staphylococcus aureus, which is responsible for a wide range of illnesses, from minor skin infections to life-threatening conditions such as pneumonia, endocarditis, and sepsis.
Staphylococcus species are non-motile, non-spore forming, and typically occur in grape-like clusters when viewed under a microscope. They can be coagulase-positive or coagulase-negative, with S. aureus being the most well-known coagulase-positive species. Coagulase is an enzyme that causes the clotting of plasma, and its presence is often used to differentiate S. aureus from other Staphylococcus species.
These bacteria are resistant to many commonly used antibiotics, including penicillin, due to the production of beta-lactamases. Methicillin-resistant Staphylococcus aureus (MRSA) is a particularly problematic strain that has developed resistance to multiple antibiotics and can cause severe, difficult-to-treat infections.
Proper hand hygiene, use of personal protective equipment, and environmental cleaning are crucial measures for preventing the spread of Staphylococcus in healthcare settings and the community.
Coagulase is a type of enzyme produced by some bacteria, including Staphylococcus aureus. This enzyme helps the bacteria to clot blood plasma by converting an inactive precursor (prothrombin) into thrombin, which then converts fibrinogen into fibrin to form a clot. The ability of S. aureus to produce coagulase is often used as a diagnostic criterion for this bacterium, and it also plays a role in the virulence of the organism by helping it to evade the host's immune system.
Staphylococcus aureus is a type of gram-positive, round (coccal) bacterium that is commonly found on the skin and mucous membranes of warm-blooded animals and humans. It is a facultative anaerobe, which means it can grow in the presence or absence of oxygen.
Staphylococcus aureus is known to cause a wide range of infections, from mild skin infections such as pimples, impetigo, and furuncles (boils) to more severe and potentially life-threatening infections such as pneumonia, endocarditis, osteomyelitis, and sepsis. It can also cause food poisoning and toxic shock syndrome.
The bacterium is often resistant to multiple antibiotics, including methicillin, which has led to the emergence of methicillin-resistant Staphylococcus aureus (MRSA) strains that are difficult to treat. Proper hand hygiene and infection control practices are critical in preventing the spread of Staphylococcus aureus and MRSA.
Staphylococcus epidermidis is a type of coagulase-negative staphylococcal bacterium that is commonly found on the human skin and mucous membranes. It is a part of the normal flora and usually does not cause infection in healthy individuals. However, it can cause serious infections in people with weakened immune systems or when it enters the body through medical devices such as catheters or artificial joints. Infections caused by S. epidermidis are often difficult to treat due to its ability to form biofilms.
Medical Definition: Staphylococcus epidermidis is a gram-positive, catalase-positive, coagulase-negative coccus that commonly inhabits the skin and mucous membranes. It is a leading cause of nosocomial infections associated with indwelling medical devices and is known for its ability to form biofilms. S. epidermidis infections can cause a range of clinical manifestations, including bacteremia, endocarditis, urinary tract infections, and device-related infections.
Staphylococcal infections are a type of infection caused by Staphylococcus bacteria, which are commonly found on the skin and nose of healthy people. However, if they enter the body through a cut, scratch, or other wound, they can cause an infection.
There are several types of Staphylococcus bacteria, but the most common one that causes infections is Staphylococcus aureus. These infections can range from minor skin infections such as pimples, boils, and impetigo to serious conditions such as pneumonia, bloodstream infections, and toxic shock syndrome.
Symptoms of staphylococcal infections depend on the type and severity of the infection. Treatment typically involves antibiotics, either topical or oral, depending on the severity and location of the infection. In some cases, hospitalization may be necessary for more severe infections. It is important to note that some strains of Staphylococcus aureus have developed resistance to certain antibiotics, making them more difficult to treat.
'Blastocystis hominis' is a species of microscopic single-celled organisms (protozoa) that can inhabit the human gastrointestinal tract. It is often found in the stool of both healthy individuals and those with gastrointestinal symptoms. The role of 'Blastocystis hominis' as a pathogen or commensal organism remains a subject of ongoing research and debate, as some studies have associated its presence with various digestive complaints such as diarrhea, abdominal pain, and nausea, while others suggest it may not cause any harm in most cases.
Medical professionals typically do not consider 'Blastocystis hominis' a primary pathogen requiring treatment unless there is clear evidence of its involvement in causing symptoms or if the individual has persistent gastrointestinal issues that have not responded to other treatments. The recommended treatment, when necessary, usually involves antiprotozoal medications such as metronidazole or tinidazole. However, it's essential to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan.
"Methicillin resistance" is a term used in medicine to describe the resistance of certain bacteria to the antibiotic methicillin and other related antibiotics, such as oxacillin and nafcillin. This type of resistance is most commonly associated with Staphylococcus aureus (MRSA) and coagulase-negative staphylococci (MRCoNS) bacteria.
Bacteria that are methicillin-resistant have acquired the ability to produce an additional penicillin-binding protein, known as PBP2a or PBP2'', which has a low affinity for beta-lactam antibiotics, including methicillin. This results in the bacteria being able to continue growing and dividing despite the presence of these antibiotics, making infections caused by these bacteria more difficult to treat.
Methicillin resistance is a significant concern in healthcare settings, as it can lead to increased morbidity, mortality, and healthcare costs associated with treating infections caused by these bacteria. In recent years, there has been an increase in the prevalence of methicillin-resistant bacteria, highlighting the need for ongoing surveillance, infection control measures, and the development of new antibiotics to treat these infections.
Anti-bacterial agents, also known as antibiotics, are a type of medication used to treat infections caused by bacteria. These agents work by either killing the bacteria or inhibiting their growth and reproduction. There are several different classes of anti-bacterial agents, including penicillins, cephalosporins, fluoroquinolones, macrolides, and tetracyclines, among others. Each class of antibiotic has a specific mechanism of action and is used to treat certain types of bacterial infections. It's important to note that anti-bacterial agents are not effective against viral infections, such as the common cold or flu. Misuse and overuse of antibiotics can lead to antibiotic resistance, which is a significant global health concern.
Microbial sensitivity tests, also known as antibiotic susceptibility tests (ASTs) or bacterial susceptibility tests, are laboratory procedures used to determine the effectiveness of various antimicrobial agents against specific microorganisms isolated from a patient's infection. These tests help healthcare providers identify which antibiotics will be most effective in treating an infection and which ones should be avoided due to resistance. The results of these tests can guide appropriate antibiotic therapy, minimize the potential for antibiotic resistance, improve clinical outcomes, and reduce unnecessary side effects or toxicity from ineffective antimicrobials.
There are several methods for performing microbial sensitivity tests, including:
1. Disk diffusion method (Kirby-Bauer test): A standardized paper disk containing a predetermined amount of an antibiotic is placed on an agar plate that has been inoculated with the isolated microorganism. After incubation, the zone of inhibition around the disk is measured to determine the susceptibility or resistance of the organism to that particular antibiotic.
2. Broth dilution method: A series of tubes or wells containing decreasing concentrations of an antimicrobial agent are inoculated with a standardized microbial suspension. After incubation, the minimum inhibitory concentration (MIC) is determined by observing the lowest concentration of the antibiotic that prevents visible growth of the organism.
3. Automated systems: These use sophisticated technology to perform both disk diffusion and broth dilution methods automatically, providing rapid and accurate results for a wide range of microorganisms and antimicrobial agents.
The interpretation of microbial sensitivity test results should be done cautiously, considering factors such as the site of infection, pharmacokinetics and pharmacodynamics of the antibiotic, potential toxicity, and local resistance patterns. Regular monitoring of susceptibility patterns and ongoing antimicrobial stewardship programs are essential to ensure optimal use of these tests and to minimize the development of antibiotic resistance.
Methicillin-Resistant Staphylococcus aureus (MRSA) is a type of bacteria that is resistant to many antibiotics, including methicillin and other related antibiotics such as oxacillin, penicillin, and amoxicillin. This bacterium can cause a range of infections, from skin infections to more severe and potentially life-threatening conditions such as pneumonia, bloodstream infections, and surgical site infections.
MRSA is often associated with healthcare settings, where it can spread through contaminated surfaces, equipment, and direct contact with an infected person or carrier. However, community-associated MRSA (CA-MRSA) has also emerged as a significant public health concern, causing infections outside of healthcare facilities, such as in schools, gyms, and other community settings.
It's important to note that while MRSA is resistant to certain antibiotics, there are still some treatment options available for MRSA infections, including vancomycin, linezolid, daptomycin, and others. However, the emergence of MRSA strains with reduced susceptibility to these antibiotics has become a growing concern, highlighting the importance of infection control measures and the development of new antimicrobial agents.
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.

- Water from each site was also cultured using methods specific to growing Staphylococcus . (flintwaterstudy.org)
Patterns1
- The optimal growth temperature range was around 28 to 40 °C, but good growth is still observed at 45 °C, while no growth is observed at 15 °C. S. hominis can be differentiated from staphylococci by its colony morphology and pigmentation patterns, predominant tetrad cell arrangement, poor growth in thioglycolate, low tolerance of NaCl, and carbohydrate reaction pattern.

Body1
- Researchers from the University of York worked with Unilever and discovered body odour has likely plagued Homo sapiens since we first evolved. (osvilt.com)
Culture1
- A total of 54 adult patients with moderate to severe AD of the ventral arms and who were culture positive for Staphylococcus aureus were enrolled in the study. (dermatologyadvisor.com)
Mice1
- All mice (40) injected intramuscularly (i.m.) with different concentrations of the purified lyophilized staphylokinase and streptokinase for 12 days, and immunized with 10% SRBCs (i.p) on day 4 and 8 of the schedule, and Staphylococcus aureus suspension and normal saline for positive and negative control groups.
