Insights

Vector-borne pathogens exploit host lipids in blood for survival and disease. This review explores how microbes like Plasmodium falciparum and Borrelia burgdorferi hijack lipids in mammals and vectors.

Area of Science:

  • Medical Microbiology
  • Parasitology
  • Vector-Borne Diseases

Background:

  • Vector-borne illnesses are a major global health concern, causing 17% of all infections.
  • Blood-feeding arthropods transmit numerous pathogens to mammalian hosts.
  • Host lipids are crucial for microbial survival, replication, and pathogenesis within blood.

Purpose of the Study:

  • To review the critical role of lipid hijacking by vector-borne microbes.
  • To explore how pathogens manipulate host lipids for growth and persistence.
  • To examine lipid utilization in both mammalian hosts and arthropod vectors.

Main Methods:

  • Literature review of scientific studies on vector-borne pathogens and host lipids.
  • Analysis of lipid metabolism and scavenging by microbes such as Plasmodium falciparum and Borrelia burgdorferi.
  • Synthesis of findings on lipid manipulation for microbial survival, replication, immune evasion, and disease severity.

Main Results:

  • Pathogens scavenge and manipulate host lipids for essential functions.
  • Lipid hijacking supports microbial structural integrity, metabolism, and replication.
  • Altered lipid metabolism contributes to immune evasion and increased disease severity.

Conclusions:

  • Lipid hijacking is a key survival strategy for vector-borne pathogens.
  • Understanding lipid-host interactions is vital for controlling vector-borne diseases.
  • Targeting microbial lipid metabolism presents a potential therapeutic avenue.

Intracellular Movement of Viruses and Bacteria

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...

Bacterial Phylum Spirochaetes

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Receptor-mediated Endocytosis

Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
