Legionella Pneumophila SG1 IgM
Legionella Pneumophila SG1 IgM
  • More than 30 species have been reported, but Legionella pneumophila serogroup 1 is responsible for most infections in humans. Atypical pneumonia is often associated with systemic manifestations. It is responsible for 10% of cases of pneumonia acquired in both the community and hospitals. During the infection, an immune response is produced against the L. pneumophila group related antigen. In the serological diagnosis of the disease, the only standardized technique is IFA. It is necessary to prove seroconversion in order to confirm a serological diagnosis since high titers may be found in healthy population. A high titer in a single serum sample together with clinical symptoms suggests illness. The use of pools of different Legionella serogroups shows seroconversions that are not confirmed with monovalent antigens. L. pneumophila serogroup 1 antigen alone should enable the serological diagnosis of 65-70% of the cases of legionnaires´s disease and avoid false positive results (Edelstein, 1992).

CANDIDA ALBICANS IFA IgG
CANDIDA ALBICANS IFA IgG
  • Invasive candidiasis is a disease of fungal ethiology with an increasing incidence, specially in immunosuppressed patients (graft receivers, neutropenic and AIDS patients, etc), long-stay hospitalized and catheterized patients, as well as those subjected to extense surgery or receiving broad spectrum antibiotic therapy. The diagnosis of invasive candidiasis is specially difficult due to the absence of pathognomonic symptoms specific of the disease and the low recovery of the microorganism in culture. The present commercial diagnostic techniques show a low specifity and sensitivity, being some of them too difficult to be carried out in a Clinical microbiology laboratory. In order to overcome these problems, a technique for the serologic diagnosis of invasive candidiasis has been developed. This test is based upon the detection of specific antibodies against antigens located on the cell wall surface of the micelium of Candida albicans. These antibodies are normally present in sera from patients with invasive candidiasis caused by C. albicans and other species of this genus. The assay is performed by indirect immunofluorescence after removal of other anti-candida antibodies usually found in most human serum, thus avoiding possible false positive results. This test can be performed with equipment available in a clinical laboratoy and is completed in 3 hours.

ENTEROCOCCUS FAECALIS (vanB) DNA Ctrl
ENTEROCOCCUS FAECALIS (vanB) DNA Ctrl
  • Bacteria in the genus Enteroccoccus are non-spore forming, facultatively anaerobic, Gram-positive cocci that often occur in pairs or short chains. E. faecalis are non-motile enterococci that can be commonly found as commensal organisms in the intestines of humans. They are able to survive in low-enriched environments such as water, soil or food. Enterococci have both an intrinsic and acquired resistance to antibiotics, making them important nosocomial pathogens, with the ability to cause life-threatening infections in humans. Infections commonly caused by enterococci include urinary tract infections, endocarditis, bacteremia, catheter-related infections, wound infections, and intra-abdominal and pelvic infections. Many infecting strains originate from the patient's intestinal flora.

Syphilis IgG/IgM
Syphilis IgG/IgM
  • Syphilis is still a common sexually transmitted disease in many areas of the world. In 1999 the WHO estimated that the worldwide annual incidence of sexually acquired syphilis was 12 million cases. Venereal syphilis is divided into: early syphilis subdivided into primary, secondary and early latent stages; late syphilis that may occur after extended periods of latent syphilis. Serological tests for syphilis are subdivided into: non treponemal tests that measure IgM and IgG antibodies to lipoidal material released from damaged host cells and antibodies to lipoprotein-like material and cardiolipin released from the treponemes. The most commonly used are RPR card and VDRL. The tests are used for screening and for determining the efficacy of threatment. They lack sensitivity in early primary syphilis and in late syphilis and it can appear a prozone reaction or false positive results. Treponema tests use T. pallidum subsp. pallidum or its derivates (recombinant proteins). They are used as confirmatory tests and in stablishing the diagnosis of late latent or late syphilis. The most commonly used tests are: FTA-ABS, TP-PA (T. pallidum particle agglutination) and MHA-IP (micro hemagglutination assay to T. pallidum). Several tests using enzyme immunoassays (EIA) have being used as confirmatory test for syphilis. they have sensitivities and specificities similar to those of the other treponemal tests.

Chlamydia Pneumoniae IgA
Chlamydia Pneumoniae IgA
  • Chlamydia has a great ability to cause respiratory infections, particularly bronchitis and pneumonia. The species most implicated in respiratory infections are Chlamydophila pneumoniae and Chlamydophila psittaci. The higher incidence takes place in elderly people and it is considered responsible of 10% of all the cases of pneumonia, although it has been considered by some authors as the most frequent cause of those cases of known ethiology. C. pneumoniae has been associated with the stablishment of ateromatous disease and heart attach. The seroprevalence to C. pneumoniae is low in infants but it can be higher than 50% in adults. In primoinfections IgM antibodies appear before than IgG antibodies while in reinfections IgM is rare, but IgG seroconversion takes place before. COMP (Complexes of Outer Membrane Proteins) antigen is used in the present assay, with LPS removed to avoid cross-reaction with other Chlamydias.

SALMONELLA ENTERITIDIS DNA Ctrl
SALMONELLA ENTERITIDIS DNA Ctrl
  • Salmonella are Gram-negative, facultative anaerobic, motile, rod-shaped bacteria belonging to the family Enterobacteriaceae. Most types of Salmonella live in the intestinal tracts of animals and birds and are transmitted to humans through contaminated food. Salmonella enterica serotype enteritidis is one of the most common serotypes of Salmonella bacteria reported worldwide and an important cause of human illness. Infection causes fever, abdominal cramps, and diarrhea beginning 12 to 72 hours after consuming a contaminated food. Eggs have been the most common food source linked to infection by serotype enteritidis, since it can silently infect the ovaries of healthy hens and contaminate the eggs before the shells are formed.

Dengue IgM (Capture)
Dengue IgM (Capture)
  • Dengue (DF) and dengue hemorrhagic fever (DHF) are caused by one of four closely related, but antigenically distinct, virus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4), of the genus Flavivirus. DF and DHF are primarily diseases of tropical and sub tropical areas, and the four different dengue serotypes are maintained in a cycle that involves humans and the Aedes mosquito. Infections produce a spectrum of clinical illness ranging from a nonspecific viral syndrome to severe and fatal hemorrhagic disease. Clinical manifestations include rash, sudden onset of fever, chills, severe headache, nausea, myalgias and arthralgias, leukopenia, thrombocytopenia and hemorrhagic manifestations. It occasionally produces shock and hemorrhage, leading to death. Important risk factors for DHF include the strain of the infecting virus, as well as the age, and especially the prior dengue infection history of the patient. Dengue viraemia appears to be universal in febrile patients with dengue; it occurs prior to the onset of fever and symptoms and peaks 2–3 days after the onset of illness. A diagnosis of acute infection with dengue virus can be made by isolating the virus or by detecting viral genome or antigen. Serologically, a primary infection with dengue virus results in detectable levels of IgM antibodies by the third afebrile day after infection. These IgM antibodies persist for 1–2 months after infection. IgG antibodies are detected approximately 14 days after onset of primary infections. Secondary infections with dengue virus are characterized by a rapid increase in IgG antibody levels. Owing to the relatively late increase in antibody levels to a concentration that can be detected diagnostically, a negative result for an antibody test early in the course of disease is not definitive. Specimens should be collected at least 7 days after the onset of symptoms in order to rule out the possibility of an acute infection with dengue virus. Serology is the most widely applied method used in routine diagnosis. Traditionally, hemagglutination inhibition and virus neutralization tests have been used. At present ELISAs for IgM and IgG antibodies are the standards for the serological analysis of dengue virus infections, as they are simple and allow large numbers of samples to be tested.
