This video demonstrates the generation of a mouse model with a CNS infection. A suckling pup is injected with the virus both intracranially and intraperitoneally. The virus spreads, infecting the CNS causing neuronal cell death and inflammation. The pup is assessed for symptoms of infection as the disease progresses.

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations for hemodynamic monitoring, medication delivery, and blood sampling. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the femoral vein. Central venous access via the subclavian vein has several advantages over other possible locations. The subclavian...

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT Central venous access devices (CVAD), commonly known as central lines or central catheters, are large-bore intravenous (IV) catheters that are introduced into the central circulation. Typically, CVADs terminate in the superior vena cava, just outside of the right atrium of the heart, but they may also terminate in any one of the great veins (i.e., aorta, inferior vena cava, brachiocephalic...

FAQs
After microorganisms attach to the catheter surface, they can organize into biofilms, which act as a persistent microbial reservoir. This growth makes the organisms more difficult for host defenses and antimicrobial treatment to reach or eliminate. The mechanism explains why preventing contamination at every access point is important, rather than relying only on treatment after bloodstream infection develops.
Microorganisms may enter through the insertion site, contaminated hands or equipment, or the catheter hub. These routes represent different prevention challenges: insertion requires sterile technique and skin antisepsis, while handling requires hand hygiene and careful equipment practices. Hub disinfection addresses contamination introduced during catheter access. Separating these pathways helps clinical teams target prevention measures more precisely.
A central line that is no longer needed continues to provide a surface and access point through which microorganisms may reach the bloodstream. Removing it eliminates those ongoing opportunities for contamination, attachment, and biofilm persistence. In clinical practice, reviewing whether the catheter remains necessary and removing it promptly when it does not support care is therefore an important risk-reduction measure.
Standardized CLABSI definitions give healthcare teams a consistent framework for identifying and counting infections associated with central venous catheters. The resulting surveillance data can reveal infection patterns, support quality-improvement work, and help evaluate whether prevention practices are reducing risk. These definitions therefore connect individual catheter safety practices with broader monitoring of healthcare-associated infection outcomes.
Prevention begins with sterile insertion and continues through hand hygiene and appropriate skin antisepsis. These measures address contamination from personnel and the insertion site before microorganisms can reach the catheter or bloodstream. Treating them as a coordinated practice is important because failure at one stage can provide an entry route even when other parts of the insertion process are performed correctly.
The catheter hub is a potential access point for microorganisms whenever the line is handled. Disinfecting it helps reduce contamination introduced during catheter access, while hand hygiene limits transfer from the hands of healthcare workers. Together, these practices address maintenance-related risks that occur after insertion and complement sterile technique and skin antisepsis used at the beginning of catheter placement.
Clinical teams can combine standardized infection surveillance with review of insertion, maintenance, and catheter-necessity practices. Monitoring outcomes helps identify whether hand hygiene, skin antisepsis, hub disinfection, sterile insertion, and timely line removal are being applied effectively. This approach links infection-control procedures to patient safety, reduced preventable illness, and improvement in outcomes associated with central venous catheter care.
