The design of a straightforward one-day workflow scheme for bacterial pathogen diagnostics enables the rapid recognition of bloodstream infections. The inclusion of eight clinically relevant bacterial targets and their antibiotic resistance profiles offers the clinician an initial insight on the same day, which can lead to more adequate therapy.

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.

A PCR-based protocol was adapted to detect Cronobacter spp., Salmonella enterica, and Listeria monocytogenes from body surfaces and alimentary canals of individual wild-caught flies. The goal of this protocol is to detect and isolate bacterial pathogens from individual insects collected as part of an environmental sampling program during foodborne outbreak investigations.

Anxiety is a commonly observed behavioral disorder that stems from fear. It is described as increased restlessness, or unpleasant feelings of fear over anticipated events. Experimenters often use rodent models to better understand anxiety disorders in humans. They use different paradigms, like exposing rodents to bright spaces or loud sounds, which are known to induce fear. These tests combined with other interventions such as surgery or drug-administration may assist researchers in pinpointing...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Wood is a ubiquitous material that has been used in construction from the earliest times. Wood is a renewable, sustainable material with great aesthetic value. Today, there are probably more buildings constructed with wood than any other structural material. Many of these buildings are singlefamily residences, but many larger apartment buildings, as well as commercial and industrial buildings,...
FAQs
Culture-based testing grows microorganisms that remain viable in a sample, providing evidence that living organisms are present under the test conditions. PCR instead detects pathogen-specific genetic material, which can reveal a target even when growth is not demonstrated. This distinction helps interpret results appropriately, especially when assessing contamination in seafood, processing environments, or surrounding waters.
Immunological methods identify microbial antigens, which are substances recognized by specific immune-based reagents. They provide a detection approach that differs from both microbial growth and genetic analysis. Including antigen recognition in the testing strategy can broaden the ways laboratories identify pathogens in seafood or environmental samples, depending on which target and evidence the investigation requires.
Testing only the seafood product may not reveal where contamination originated or whether it persists around production activities. Samples from surrounding waters and processing environments add environmental context, helping connect findings with coastal or aquaculture conditions and sanitation practices. Comparing these sample sources can support contamination monitoring and help identify points requiring closer risk management.
Each approach supplies a different type of evidence: culture demonstrates growth of viable organisms, PCR detects pathogen-specific genetic material, and immunological assays recognize microbial antigens. Agreement among methods can strengthen interpretation, while differing results require attention to what each method actually measures. This complementary perspective is useful when evaluating contamination, investigating outbreaks, or guiding seafood safety decisions.
Investigations may include fish and shellfish, along with samples from processing environments and surrounding waters. Product samples show whether seafood carries a target pathogen, while environmental samples help assess conditions associated with production, handling, or sanitation. Selecting more than one sample type can provide a broader picture of contamination across seafood systems and their surrounding environments.
The testing supports monitoring of aquaculture and coastal environments by examining seafood and related environmental samples for bacteria, viruses, or parasites. Results can help identify contamination concerns before products reach consumers and contribute to ongoing evaluation of production conditions. This environmental focus connects laboratory findings with food safety and public-health protection across seafood operations.
