Carrier. 1. A person or animal harboring a specific Infectious Agent in the absence of discernible clinical disease and which serves as a potential source of infection. The carrier state may occur in an individual with an infection that is inapparent throughout its course (known as a healthy or asymptomatic carrier) or the carrier state may ...

Vector and carrier are two types of agents involved in the transmission of diseases between organisms. The main difference between vector and carrier is that a vector does not show any symptoms of the disease whereas a carrier is an infected organism capable of transmitting the disease-causing microorganisms to a healthy individual. Anopheles mosqu...
Vector refers to an organism that spreads diseases by conveying pathogens from the host to another individual but without causing diseases by itself. Typically, vectors are blood feeding (haematophagous) arthropods such as mosquitoes, sandflies or ticks. Malaria, dengue fever, leishmaniasis, and West Nile virus are some examples of vector-borne dis...
Carrier refers to an organism that harbors a specific infectious agent in the absence of discernible clinical disease and serves as a potential source of infection. A carrier can be divided into three categories based on the type of disease they carry and symptoms they display: asymptomatic carrier, genetic carrier, and symptomatic carrier.
Vector and carrier are two types of agents that transmit diseases between organisms.Both vector and carrier transmit disease-causing microorganisms.Both vector and carrier are involved in the biological mechanical transfer of diseases.Disease-causing microorganisms may live on or in the body of both vector and carrier.Definition
Vector: Vector refers to an organism that spreads diseases by conveying pathogens from the host to another individual, but without causing diseases by itself. Carrier: Carrier refers to an organism that harbors a specific infectious agent in the absence of discernible clinical disease and serves as a potential source of infection.
Symptoms of the Disease
Vector: Vector does not show any symptoms of the disease. Carrier: Generally, carrier shows the symptoms of the disease as it is also an infected organism.
Genetic Diseases
Vector: Vectors generally do not transmit genetic diseases. Carrier: Carrier also transmit genetic diseases.

Bacterial carrier strains can be attenuated by targeted disruption of virulence genes allowing the fine-tuning of pathogenicity, immunogenicity and/or adjuvanticity. Molecular syringes can be modified such that modified pathogenicity factors and/or heterologous antigens are delivered to host cells.
6 Challenges and perspectives. The rapid development of synthetic biology and the integration of nanoscience and nanotechnology have brought new vitality to the use of bacteria as drug carriers. Bacterial drug carriers have attracted worldwide attention and are undergoing rapid development.
Fimbriae (plural): modern term for short, hair-like projections or appendages (organelles) on the outer surface of certain bacteria composed of protein subunits ( pilin) extending outward from the surface that act as a virulence factor by promoting adherence; formerly known as pili; fimbria (singular)

Pathogens often have elaborate adaptations to exploit host biology, behavior, and ecology to live in and move between hosts. Hosts have evolved defenses against pathogens, but because their rates of ….
Sep 5, 2022 · The classical features of an individual said to be a carrier of Streptococcus pyogenes (Group A streptococcus) is the confirmed presence of the organism in their posterior pharynx, without any of the usual attendant clinical symptoms of acute pharyngitis. This chapter provides an overview and discussion of relevant topics of S. pyogenes carriage, including its prevalence, longitudinal studies ...
