We describe a method for tracking the endomembrane rupture elicited by the intracellular bacteria Shigella flexneri and Mycobacterium tuberculosis upon host cell invasion. Our assay makes use of CCF4, a host cytoplasmic FRET probe in live or fixed cells. This reporter is degraded by an enzyme activity present on the bacterial surface.

Streptococcus pneumoniae forms discrete non-purulent microscopic lesions in the heart. Outlined is the protocol for a murine model of cardiac microlesion formation. Instruction is provided on microlesion visualization using microscopy, discrimination between early and late microlesions, and methods to detect cardiac remodeling in hearts of convalescent animals.

FAQs
The immediate danger arises when weakened cardiac tissue can no longer withstand the forces acting on it. Once tissue gives way, blood may escape into nearby spaces or move through an abnormal opening, disrupting normal circulation. Because these changes can develop quickly, a patient’s condition may worsen over a short period, making prompt recognition clinically important.
The consequences depend on whether the tear involves the heart muscle, septum, papillary muscle, or surrounding structures. A defect involving the septum can create abnormal flow between chambers, whereas disruption near the pericardial space may allow blood to collect around the heart. Thus, the anatomic site helps determine how circulation is impaired and what findings clinicians seek.
Blood entering the pericardial space can produce hemopericardium, meaning blood accumulation around the heart, and may lead to cardiac tamponade that impairs cardiac function. In contrast, a tear involving the septum can establish abnormal blood flow between chambers. These different pathways create distinct circulatory problems and influence the urgency and focus of clinical evaluation.
Concern should increase when compatible deterioration follows myocardial infarction, cardiac trauma, or an invasive procedure. These settings can leave cardiac tissue damaged or vulnerable to mechanical failure. Symptoms may progress rapidly, so clinicians must connect the timing and context of the event with possible rupture rather than treating the presentation as an isolated circulation problem.
Evaluation combines clinical assessment with cardiac imaging. The clinical assessment identifies a rapidly changing condition and considers the preceding event, while imaging helps examine the heart and surrounding structures for consequences of tissue failure. Together, these approaches support urgent diagnosis, allowing clinicians to recognize impaired circulation and determine the need for emergency intervention.
Cardiac imaging helps clarify how rupture has affected circulation, including whether blood has entered the pericardial space or abnormal flow has developed between chambers. Urgent intervention is important because hemopericardium, cardiac tamponade, or severe circulatory impairment may progress quickly. In research, the same clinical information also supports efforts to improve risk prediction and outcomes.
