Helicobacter pylori is a bacteria that lives in the lining of your stomach.h py lori It has been linked to stomach inflammation (gastritis) and peptic ulcers of the stomach, which are sores in the lining of your stomach or small intestine (duodenum).h py lori H. pylori infection is also a risk factor for certain types of stomach cancer. About two-thirds of the world’s population is infected with h pylori, which is more common in developing countries.h py lori People who are traveling or living in these countries may be more at risk of acquiring h pylori than people who live and work in their home country.h py lori H. pylori can be spread through close contact, such as sharing food or eating in the same restaurant. People can also get h pylori by drinking untreated water or ingesting contaminated food. h pylori is very delicate and needs to be cultured as soon as possible after sampling.h py lori If you have a peptic ulcer or are unsure if you have one, talk to your doctor about getting a sample of your stomach lining (biopsy) and sending it to the laboratory for testing for h pylori.h py lori Biopsies can be obtained by a flexible viewing tube…

Diagnostic medical involves the process of identifying a disease or health condition from its signs and symptoms.diagnostic medical The goal of this is to allow healthcare professionals to provide patients with the best care possible. Diagnostic services include clinical examination, laboratory tests, and imaging to help identify problems such as cancer, infections, or heart conditions. Diagnostic procedures often involve the use of a combination of tools to ensure the most accurate diagnosis, such as combining imaging techniques with lab tests like blood work or biomarker analysis in cases of suspected cancer. The diagnostic process is an iterative one in which clinicians collect information through a variety of approaches and then integrate and interpret this data to establish a working diagnosis (Varghese, 2011).diagnostic medical Gathering and evaluating the information may be done by taking a patient’s history, performing a physical exam, ordering diagnostic testing, consulting or referring with other practitioners, or using other resources such as electronic health records. A patient’s demeanor, complexion, posture, and level of distress can also be assessed to determine a diagnosis. This information can help narrow the list of potential diagnoses and may assist in avoiding unnecessary diagnostic testing or treatment options. Once a working diagnosis is determined, the next step in the process is to

During the first 3 days after a dengue fever infection, the immune system produces IgM antibodies to neutralize the virus.dengue ns1 igg igm This test detects the presence of these IgM antibodies in your blood sample. If the test result is negative, it means that you have not been infected or that your IgM antibodies have reverted back to normal (during early phase of infection). On the other hand, if the test result is positive, then you probably have been infected recently and that your IgG antibodies are still present in the body. This test can also be used to check for past infections as well. The test detects antibodies to the NS1 protein of the dengue virus in your blood sample.dengue ns1 igg igm It is a rapid chromatographic immunoassay and can be performed on whole blood, serum or plasma samples. It is easy to use and the results can be interpreted within 15-20 minutes. The result can be used to aid in the diagnosis of the disease as well as follow up of patients with suspected acute or convalescent dengue fever. Dengue is a mosquito-borne disease and spreads due to bite of infected aedes aegpti mosquito. It can lead to severe disease in some patients and even death.

Dengue is one of the most important mosquito-borne viruses worldwide and causes significant disease burden in tropical and subtropical regions.dengue ns1 Early diagnosis of the disease significantly reduces associated morbidity and mortality. The non-structural protein 1 (NS1) of the virus is a highly conserved target for serological diagnostic tests and can be measured in blood samples taken during the first 7 days of illness to indicate current or recent infection.dengue ns1 A positive NS1 test result meets the laboratory criteria for confirmation of a dengue case in the National Notifiable Diseases Surveillance System (NNDSS). There are several commercial NS1 ELISA tests available in the market and some public health and private laboratories use these kits. However, a negative NS1 result does not rule out a recent dengue virus infection, as the sensitivity and specificity of the tests may vary. Our objective was to evaluate the performance of a bedside NS1 antigen rapid test in predicting the severity of dengue in patients admitted to hospital.dengue ns1 We recruited 186 patients hospitalized with dengue fever who underwent serum determination of NS1 on day 3-8 of their illness. Patients were grouped according to the occurrence of warning signs and/or severe dengue (defined as fluid leakage, bleeding manifestations or platelet count 25,000 cells/mm3). The bedside NS1 antigen rapid test had comparable

Cryptococcus neoformans and its cousin Cryptococcus gattii are opportunistic fungal pathogens that cause life-threatening infections in immunocompromised individuals.cryptococcus neoformans They belong to the Basidiomycota and are facultative intracellular yeasts (Chang, 2008). They are found in the environment as basidiospores or desiccated yeast cells and can be inhaled from contaminated dust. The infections they cause can occur throughout the body, but most commonly in the lungs and central nervous system (cryptococcal meningitis, CCM). C. neoformans is globally distributed and most cases of infection are related to inhalation of the fungus from bird droppings (most commonly, pigeon feces) or from close contact with pigeons. Direct human-to-human transmission is rare, but has been reported after organ transplantation and in patients with severe combined immune deficiency. Initially, cryptococcosis develops in the lungs as a pneumonia-like illness with nonspecific symptoms, but can also spread to the brain and other parts of the body, including the skin.cryptococcus neoformans This infection can be difficult to diagnose and is more common in people with advanced HIV/AIDS. Other risk factors include long-term corticosteroid use and hematologic cancers. It is not known if the infections caused by these two species differ in severity or pathogenesis, but their different clinical presentations have led

Immunoassays are a critical tool for clinical diagnostic laboratories.chemiluminescence immunoassay They are used to detect antibodies, antigens, hormones, and disease markers in biological samples. They are also used in forensic sciences for criminal investigations and paternity testing. There are many different immunoassay methods, but chemiluminescence is one of the most popular for its sensitivity, wide dynamic range, and linear relationship between light intensity and concentration. Chemiluminescence immunoassay is a variation of enzyme-linked immunosorbent assay (ELISA).chemiluminescence immunoassay It uses antibody or antigen to bind with a luminescent substrate, which emits light when oxidized. This process is triggered by an enzyme, such as horseradish peroxidase. This oxidation creates a free radical that is detected by a luminometer. This luminescent signal is directly proportional to the concentration of the analyte in the sample. A chemiluminescent assay can be a great choice for analyzing a large number of samples because of its fast results and high sensitivity. It is also simple to use, and it does not require any special equipment or training. In addition, chemiluminescence immunoassay can detect low-concentration analytes that are not detectable by other assay methods. This makes it a very useful technique for laboratories with limited space or budget. Various types of chemiluminescent immunoassays

When a part of the heart is damaged during a heart attack, it releases troponin into the bloodstream.cardiac troponin A high level of troponin can tell a doctor that part of the heart muscle has been injured, but it can’t tell if it was a heart attack or something else that caused the damage. Troponin tests are usually used in the emergency room to help diagnose a heart attack or other problems that may be causing chest pain and other symptoms. A phlebotomist (a health care worker who draws blood samples) will use a needle to take a small sample of your blood and send it to a lab for testing.cardiac troponin A new version of the test is more sensitive and can detect even smaller amounts of troponin in your blood. This can help doctors get more accurate results more quickly. The new versions of this test are also less likely to be affected by dietary supplements like vitamins B7 and C, which can make the results look lower than they actually are. Most people who are having a heart attack have higher-than-normal levels of troponin in their blood.cardiac troponin The higher troponin levels stay in the blood for about 12 hours after the heart

Carbapenemase kpc is an emerging resistance mechanism for a broad range of Gram-negative bacteria including Klebsiella pneumonia.carbapenemase kpc Detection of the gene encoding for this carbapenemase enables the clinician to identify resistant strains in patients with suspected GNB infections. Various diagnostic platforms based on molecular methods can rapidly identify the presence of blaKPC in positive blood cultures and rectal swabs. Some of these are able to detect blaKPC and other clinically relevant resistance genes in as little as 1 hour compared to conventional microbiological methods that can take up to 72 hours. The occurrence of resistance mechanisms such as carbapenemases is a major challenge to the effectiveness of antibiotic therapy in hospitalised patients.carbapenemase kpc Rapid detection of the blaKPC gene in such strains is important to ensure early initiation of appropriate and targeted therapies. There are several diagnostic platforms that can detect the presence of blaKPC in a single reaction with lysates from gram-negative bacteria. These include a commercial real-time polymerase chain reaction (PCR) system called Xpert Carba-R which can identify blaKPC and other resistance genes from positive blood cultures or swabs in a single assay, and a mass spectrometry-based system such as FilmArray BC-ID that can detect the presence of blaKPC and other resistance genes in

Humans generally acquire the disease through direct contact with infected animals, by eating or drinking contaminated animal products or by inhaling airborne agents. Most cases are caused by ingesting unpasteurized milk or cheese from infected goats or sheep.      Brucellosis is one of the most widespread zoonoses transmitted by animals and in endemic areas, human brucellosis has serious public health consequences. Expansion of animal industries and urbanization, and the lack of hygienic measures in animal husbandry and in food handling, partly account for brucellosis remaining a public health hazard. Who is at risk?  Brucellosis is found globally and is a reportable disease in most countries. It affects people of all ages and both

Blood culture system is a method of testing a sample of your blood for infection. A laboratory technician places your blood in a special dish (culture) that contains an artificial medium that supports the growth of bacteria and some types of fungus. Then, the technician watches to see if any germs grow in the culture. If the results show that you have an infection, your doctor may prescribe antibiotics to treat it. Blood cultures help your doctor diagnose infections in many parts of your body, such as the lungs, heart, joints, and bones. A blood culture can also show how extensive the infection is and whether it has spread to other parts of your body, including the brain (septic shock). Blood cultures are used to help determine the best course of treatment and to monitor progress during treatment. Whether a blood culture is helpful or not depends on the ability of your body to fight the infection and how long the organisms are present in your bloodstream. Blood culture sensitivity decreases in certain groups of patients, such as neutropenic cancer patients. Also, blood culture sensitivity can be reduced by repeated blood draws and inadequate sampling. In addition, a single set

Adenovirus is a family of viruses that infects various parts of the human body. Symptoms of infection range from mild common cold-like symptoms (sore throat, runny nose, coughing, chills) to bronchitis, pneumonia or pink eye. Young children and people with weakened immune systems are more likely to develop severe adenovirus infections. Adenovirus can spread by close contact (shaken hands, kissing, hugging), through respiratory droplets released in sneezes and coughs, and by touching surfaces or objects with the virus on them and then touching your eyes, mouth or nose before washing your hands. Occasionally, intestinal adenovirus can cause a serious medical emergency called intussusception, in which one part of the intestine slides over another section like a telescope and causes abdominal pain, vomiting and diarrhea. A slender, rod-shaped virus with a diameter of 70 to 100 nm, adenovirus consists of 252 capssomeres forming the icosahedral structure, each bearing two major core proteins and a short fiber that extends from the center of the capsid. Adenoviruses replicate in cells by dividing their genomes twice and then inserting the new DNA into the cell nucleus. The resulting DNA fragments are then packaged into capssomeres for further replication and release. Adenoviruses have also been used as vector systems in approaches
