Corynebacterium diphtheriae is the etiological agent of diphtheria and occurs in 2 forms, respiratory and cutaneous diphtheria. Respiratory diphtheria may be further classified into pharyngeal, tonsillar, laryngeal, and the less common anterior nasal diphtheria. Due to vaccination programs in the United States, diphtheria is now a rarely reported disease. Corynebacterium diphtheriae is primarily spread by droplets from coughing or sneezing. The incubation period averages 2 to 5 days. The illness is characterized by fever, malaise, and sore throat with a distinguishing thick pseudomembrane present over the involved mucosa. A swab from beneath the pseudomembrane is the preferred specimen for culture. The organisms multiplying at the infection site produce a toxin, diphtheria toxin, which may result in systemic complications affecting the heart, nervous system, etc.

As a general rule, invading pathogens, such as bacteria, viruses, fungi and so on, cause a lot of harm on their own. For example, a virus may take over a cell for reproduction, which may end up destroying that cell in the process. Sometimes, however, it's not the pathogen itself that causes a lot of harm, it's what the pathogen releases. I like to think of one particular bacterium as a kind of alien mother ship that shoots out laser beams that end up doing more damage than the mother ship itself.

Testing should buy keflex 250mg not be ordered to monitor the effectiveness of treatment or for those who are symptomatic.

Molecular tests may remain positive for weeks after someone is cured and asymptomatic.

Some of these will go on to develop fulminant CDI, resulting in approximately 300 deaths per day. It may be also used to treat other conditions, such as IBS, colitis, constipation and some neurological conditions.
