NEISSERIA MENINGITIDIS SEROGROUP B DNA Ctrl
Neisseria meningitidis or meningococcus is a Gram-negative,
oxidase-positive, aerobic, coccal bacterium that appears
microscopically under diplococcal arrangement. Strains are
serogrouped on the basis of their capsular polysaccharides.
The meningococcus usually inhabits the human nasopharynx
without causing detectable disease. It may cause
Toxoplasma gondii is a protozoan that presents three stages in
its developmental life cycle: oocyst, tachyzoite and bradyzoite.
While only members of the family Felidae can be definitive
hosts of the parasite, a great variety of animals can harbour
the tissue cysts. Although consuming contaminated food is the
most common way of becoming infected, transplacental
infection may occur. The disease is normally benign, but
central nervous system disease may appear in
immunocompromised patients and the newborn.
Helicobacter pylori has a worldwide distribution and a high prevalence.
The infection with H. pylori is well established as a major cause of gastric
and duodenal ulcers. The persistent infection with H. pylori is a risk factor
for the development of gastric carcinoma and lymphoma. The infection
produces elevated levels of specific H. pylori IgG and IgA antibodies in
serum. IgM specific levels has not proven useful in the clinical laboratory.
ELISA tests for the detection of H. pylori antibodies are sensitive, specific
and cost effective in untreated patiens. The detection of H. pylori specific
IgA alone is less sensitive than the detection of specific IgG antibodies. In
untreated persons specific IgG and IgA remain elevated for years and
successful eradication decreases the IgG and IgA levels, although in some
individuals specific antibodies can persist during a long time. Because the
infection with H. pylori is so prevalent the test should be performed only
on individuals with symptoms. The prevalence of H. pylori antibodies
increases with the age. A positive result only indicates that the patient has
antibodies to H. pylori and if the individual has not been treated, a positive
result very likely indicates an active infection with H. pylori. A definitive
diagnosis should be given only when the clinical signs and symptoms of
the patient are compatible.
Papillomaviruses are non-enveloped, icosahedral, double
stranded DNA viruses with a diameter of 45 to 55 nm. They
infect epithelial tissues throughout the body leading to both
benign and malignant lesions, including common and genital
warts. Papillomas caused by some types, such as human
papillomaviruses 16 and 18, are strongly associated with
cervical cancer. The control contains DNA from CaSki cells that
are reported to bear an integrated human papillomavirus type
Herpes simplex is an enveloped, icosahedral, double stranded
DNA virus with a diameter of 120 to 200 nm. Although primary
infections by herpes simplex virus type 2 can be asymptomatic,
it causes herpes genitalis; recurrent infections are common.
Zika virus (ZIKV) is an enveloped and icosahedral singlestranded
RNA virus belonging to the genus Flavivirus, member
of the Flaviviridae family and therefore evolutionarily related
to other mosquito-borne arboviruses such as dengue, yellowfever
(YFV) and West Nile virus. Clinical picture is characterized
as a 'dengue-like' syndrome, with abrupt onset of fever and an
early onset evanescent rash, often pruritic. The possible link
between Zika virus infection and microcephaly in newborns has
Bacteria of the genus Borrelia are highly motile spirochetes
with a Gram-negative bacterial type cell wall, that grow under
microaerophilic or anaerobic conditions. Borrelia burgdorferi
sensu lato is the causal agent of Lyme disease and includes
three human-pathogenic species: B. burgdorferi sensu stricto,
B. afzelii and B. garinii. The three species are present in
Europe, while only the former is found in North America. They
are transmitted to humans by the bite of ticks.
Parechovirus belongs to the family Picornaviridae, which
includes nonenveloped, icosahedral, single stranded RNA (+)
virus of small size (30 nm). Human parechoviruses are divided
into 14 genetic types. They replicate in the respiratory and
gastrointestinal tract. Infection is particularly prevalent in
young children but it is often asymptomatic. They may cause
respiratory infections and diarrhea. They have been
occasionally associated to infections of the central nervous
Competitive immunoenzymatic colorimetric method for quantitative determination of Aldosterone concentration in human serum, human plasma or urine.
Aldosterone ELISA kit is intended for laboratory use only.
Type 1 diabetes, also known as insulin-dependent diabetes mellitus (IDDM), results from a chronic autoimmune destruction of the insulin-secreting pancreatic beta cells, probably initiated by exposure of genetically susceptible host to an environmental agent. Autoimmune destruction of beta cells is thought to be completely asymptomatic until 80 - 90 % of the cells are lost. This process may take years to complete and may occur at any time.
Rickettsia are obligate intracellular, coccobacillary bacteria
with a Gram-negative cell wall structure. Rickettsia conorii is
maintained in its natural cycle by transovarian transmission in
ticks. It is the causal agent of the Mediterranean spotted fever.
