Is Aeromonas infection contagious?
Aeromonas-induced diarrhea is a contagious disease seen in both industrialized and developing countries in all age groups (3).
How do you get Aeromonas infection?
Wound infections are the second-most common type of human infection associated with Aeromonas. They are associated with penetrating wounds or abrasions that place the wound in contact with fresh water or soil.
How is Aeromonas hydrophila transmitted to humans?
MODE OF TRANSMISSION: Infection is spread via fecal-oral transmission during direct ingestion or drinking of contaminated water or foods 1, 11, 14. Infection can also be transmitted by eating contaminated meat, dairy, shrimp, or fish 1.
What disease does Aeromonas cause?
Diarrheal disease is the most common manifestation of Aeromonas infection. The organism has also been associated with a variety of extraintestinal presentations, including wound infections and bacteremia.
How do you treat Aeromonas?
Intravenous gentamicin or a fluoroquinolone such as ciprofloxacin is recommended for the treatment of serious Aeromonas infections. Trimethoprim and ciprofloxacin are good choices for oral therapy. Abrutyn, E. (1988).
How can you tell Aeromonas?
Approach to Identification: Aeromonas species are facultative anaerobes that are oxidase and catalase positive. This test must be performed on media without a fermentable sugar (ie MacConkey agar), because the fermentation process results in acidification of the medium and a false-negative result may result.
What antibiotic treats Aeromonas hydrophila?
Successful drainage in addition to appropriate antibiotic therapy is essential for successful treatment. Fluoroquinolones, 3rd- or 4th-generation cephalosporins, and aminoglycosides are considered the drugs of choice for patients with Aeromonas biliary tract infections (22, 125).
How do you treat an infection in Aeromonas?
Is Aeromonas a fermenter?
Aeromonas spp are oxidase-positive, polar flagellated, glucose-fermenting, facultatively anaerobic, gram-negative rods that are resistant to the vibriostatic agent O/129 and unable to grow in 6.5 percent NaCl.
How many Aeromonas species are there?
Of the 14 species in the genus, Aeromonas hydrophila, Aeromonas veronii, Aeromonas caviae, Aeromonas jandaei, and Aeromonas schubertii have been associated with human disease; the first three are defined as major pathogens and the species associated with gastroenteritis.
What is the role of Aeromonas spp in human health?
Aeromonads are important enteric pathogens, but, with the growing level of immunosuppression in the population, they have been associated with various extraintestinal infections, such as skin and soft-tissue infections, traumatic wound infections, and lower respiratory tract/urinary tract infections.
What are the diseases caused by Aeromonas?
Aeromonas spp. can produce several diseases in wild and farmed freshwater and marine fish species impacting the economy of the aquaculture sector. Most common human clinical presentations of Aeromonas infections are diarrhea, wound and soft-tissue infections and bacteremia.
Are Aeromonas autochthonous to water?
Aeromonas are considered autochthonous of the aquatic environments, and in agreement with that, water was the origin in the description of 11 of the 32 (34.4%) species, with seven from fish and two from shellfish (Table 1). The second most frequent origin, with nine species (28.1%) is human.
What are the characteristics of Aeromonas species?
Species of Aeromonas are Gram-negative, non-spore-forming, rod-shaped, facul- tatively anaerobic bacteria that occur ubiquitously and autochthonously in aquatic environments.
What are the treatment options for Aeromonas Aeromoniasis?
Treatment of chronic diarrhea with trimethoprim-sulfamethoxazole (131) and acute diarrhea in a putative outbreak with ciprofloxacin ( 117) has been reported. Nevertheless, due to lack of controlled clinical trials and the increasing antibiotic resistance in Aeromonas species, the optimal regimen for such infections is not defined.
