Insights

Rickettsioses, infectious diseases in Europe, are evolving. New tick-borne and flea-borne Rickettsia species now cause human infections, with potential for epidemic typhus reemergence.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Public Health

Background:

  • Rickettsioses are endemic infectious diseases in Europe.
  • Mediterranean spotted fever (Rickettsia conorii) was historically the primary recognized tick-borne rickettsiosis.
  • Recent discoveries reveal emerging tick-borne and flea-borne Rickettsia species impacting human health.

Purpose of the Study:

  • To review the current landscape of rickettsioses in Europe.
  • To highlight newly identified Rickettsia species involved in human infections.
  • To underscore the potential for future emergence and reemergence of rickettsial diseases.

Main Methods:

  • Literature review of recent epidemiological and etiological data on rickettsioses in Europe.
  • Analysis of newly implicated Rickettsia species in human pathology.
  • Assessment of factors contributing to disease emergence.

Main Results:

  • Several new Rickettsia species (R. slovaca, R. sibirica mongolotimonae, R. helvetica) are now linked to tick-borne human infections.
  • Flea-borne rickettsioses caused by R. typhi and R. felis have been documented.
  • The potential for epidemic typhus reemergence in central and southern Europe requires vigilance.

Conclusions:

  • The spectrum of rickettsioses in Europe is expanding beyond Mediterranean spotted fever.
  • Emerging tick-borne and flea-borne Rickettsia infections pose a growing public health concern.
  • Climate change and other factors may drive the emergence of novel rickettsial diseases.

Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Rabies01:28

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
American Trypanosomiasis01:22

American Trypanosomiasis

Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Bacterial Phylum Spirochaetes01:30

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 by a...
Intracellular Movement of Viruses and Bacteria01:10

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 virus that...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
