Summary
Triatominae bugs, vectors of Chagas disease, are spreading globally. This review explores their potential to transmit other infectious agents, like Serratia marcescens and Bartonella, to humans.
Area of Science:
- Medical Entomology
- Public Health
- Infectious Diseases
Background:
- Triatominae bugs transmit Chagas disease, a significant public health issue, particularly in Latin America.
- Global population mobility facilitates the spread of these vectors to non-endemic regions.
- The worldwide distribution of Triatominae raises concerns about their potential to harbor and transmit diverse pathogens.
Purpose of the Study:
- To review the literature on infectious agents transmitted to humans by Triatominae bugs.
- To assess the competence of Triatominae as vectors for pathogens beyond Trypanosoma cruzi.
- To understand how co-infections might influence Chagas disease transmission.
Main Methods:
- Comprehensive literature search for studies on Triatominae and human infectious agents.
- Analysis of reported cases and experimental evidence of pathogen transmission by Triatominae.
- Review of research on the impact of co-infections on vector competence.
Main Results:
- Triatominae species are found globally, not just in the Americas.
- Evidence suggests Triatominae may transmit pathogens such as Serratia marcescens, Bartonella, and Mycobacterium leprae.
- Co-infections with other microorganisms can alter Triatominae's ability to transmit Trypanosoma cruzi.
Conclusions:
- Triatominae's global presence poses a risk for the spread of various infectious diseases.
- Further research is needed to fully understand the vector competence of Triatominae for diverse pathogens.
- Interactions between pathogens within Triatominae could impact Chagas disease epidemiology.

In electrostatics, the electric field can be written as the negative gradient of the potential. In magnetostatics, the zero divergence of the magnetic field ensures that the magnetic field can be expressed as the curl of a vector potential. This potential is known as the magnetic vector potential.

3.6K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Vectors are mathematical entities characterized by both magnitude and direction. Unlike scalars, which are defined solely by magnitude, vectors represent quantities like displacement, velocity, and force, where direction is essential. Vectors are graphically represented as directed line segments, extending from an initial point to a terminal point, denoted with bold letters or arrows placed above the symbol. Two vectors are deemed equal if they share identical magnitudes and directions,...

42.7K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...
