What are the pyogenic infections?

Infections in which pus is produced are known as pyogenic, that is, pus-producing infections. A wound, whether surgical or accidental, has a tendency to become infected. Strains of Staphylococcus aureus, which are resistant to many of the available antibiotics, are not uncommon in hospitals.

What are the common infections of CNS?

Acute CNS infections fall broadly into three categories—meningitis, encephalitis, and abscesses—and generally result from blood-borne spread of the respective microorganisms.

What bacteria causes pyogenic infections?

About 65% of the clinical specimens were positive for the bacterial growth and Gram positive bacteria (57.4%) were the leading pathogens among pyogenic wound infections. Staphylococcus aureus (412, 49.28%), Escherichia coli (136, 16.27%), Klebsiella spp. (88, 10.53%), and Pseudomonas spp.

How is pyogenic infection diagnosed?

Diagnosis of pyogenic liver abscess

an abdominal ultrasound to locate an abscess.
a CT scan with intravenous contrast, or injected dye, to find and measure the abscess.
blood tests to look for signs of infectious inflammation, such as an increased serum white blood count and neutrophil level.

What causes CNS infection?

The most common causes are enteroviruses (e.g., Coxsackie A & B, echovirus). Herpes simplex virus (HSV, types 1 and 2), cytomegalovirus (CMV), Epstein-Barr virus (EBV), varicella zoster virus (VZV), mumps virus, and HIV may also cause viral meningitis.

What is pyogenic meningitis?

Pyogenic meningitis, also referred as bacterial meningitis, is a life-threatening CNS infectious disease affecting the meninges, with elevated mortality and disability rates. Three bacteria (Haemophilus influenzae, Streptococcus pneumoniae, Neisseria meningitidis) account for the majority of cases 4,5.

What causes pyogenic infection?

Some of the common etiological agents responsible for causing pyogenic infections are bacteria such as Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Klebsiella spp., Proteus spp., Pseudomonas spp., and Acinetobacter spp.

What is pyogenic skin infection?

The chapter discusses two important types of pyogenic skin infection which illustrate the different ways in which the skin and deeper tissues respond to infection with two types of bacterium. The coverings of the brain and spinal cord may become infected with a variety of microorganisms when the result is meningitis.

What is miscellanous pyogenes?

MISCELLANEOUS PYOGENIC INFECTIONS is an acute pyogenic infection involving mainly the urethra in the male, and in the female also the cervix of the uterus. It is caused by the coccus Neisseria gonorrhoeae, the ‘gonococcus’.

What is the difference between normal and pyogenic meningitis?

In pyogenic meningitis large numbers of leucocytes will be found whereas normal The Pyogenic Infections 83 c.s.f. contains only very occasional cells. Also bacteria can often be seen in stained films.

What are the signs and symptoms of pyogenic reactions to herpes zoster (shingles)?

A typical pyogenic reaction occurs but obvious pus is rarely to be seen. Instead the infection spreads rapidly through the skin and subcutaneous tissues, and is seen as a diffuse spreading redness.
