Common questions

What does Neisseria Lactamica cause?

What does Neisseria Lactamica cause?

lactamica causes septic arthritis, as there are case reports of septic arthritis, discitis, or bursitis caused by other commensal Neisseria spp., including N. sicca, N. subflava, and N. mucosa.

What common illness does Neisseria meningitidis cause?

Bacteria called Neisseria meningitidis cause meningococcal disease. About 1 in 10 people have these bacteria in the back of their nose and throat without being ill. This is called being ‘a carrier’. Sometimes the bacteria invade the body and cause certain illnesses, which are known as meningococcal disease.

Where is Neisseria Lactamica found?

Neisseria lactamica is a common and normally harmless commensal of the upper respiratory tract found especially in young children. In the July 2006 edition of this journal, Zavascki and colleagues reported the first case of N. lactamica causing cavitatory lung disease in an adult organ transplant recipient (3).

How do I know if I have Neisseria gonorrhoeae?

A Definitive diagnosis of gonorrhea requires: isolation of N. gonorrhoeae from sites of exposure (e.g., urethra, endocervix, throat, rectum) by culture (usually a selective medium) and demonstrating typical colonial morphology, positive oxidase reaction, and typical gram-negative morphology and.

Is Neisseria Lactamica normal flora?

Neisseria lactamica is a gram-negative diplococcus bacterium. It is strictly a commensal species of the nasopharynx.

What does Neisseria meningitidis do to the body?

Neisseria meningitidis (Nm, the meningococcus) is a leading cause of bacterial meningitis throughout the world. Besides meningitis, meningococci can cause sepsis, pneumonia and, occasionally, focal infections such as arthritis, myocarditis, pericarditis, endophthalmitis, epiglottitis, otitis and urethritis.

What is major cockle rash?

A rash can develop under the skin due to blood leakage that may leave red or brownish pinprick spots, which can develop into purple bruising. Meningococcal rash can usually be confirmed by a glass test in which the rash does not fade away under pressure.

What kind of acid does Neisseria lactamica produce?

One strain is known to be lactose-negative; this strain, however, produced beta-galactosidase in an enzyme substrate test Among the Neisseria species, N. lactamica is the probably the easiest species to identify. N. lactamica is the only species that produces acid from lactose and beta-galactosidase.

Can a Neisseria lactamica be misidentified?

Thus, with a rare exception (one known, unpublished report of a lactose-negative strain), this species should not be misidentified. An identification of N. lactamica may be confirmed by detection of beta-galactosidase in an enzyme substrate test.

Which is the best description of Neisseria sicca?

Neisseria sicca Characteristic Illustration Gram stain Cell Morphology Gram-negative diplococcus Colony Morphology Pigmentation Oxidase Test

What kind of phenol does Neisseria sicca produce?

In the 1960s, Berger and co-workers showed that Neisseria spp. produced consistent patterns of acid production from carbohydrates if isolates were tested in an appropriate medium, a medium with a low protein to carbohydrate ratio with phenol red as the pH indicator.
