Fulminant Pneumonia and Sepsis due to Aeromonas hydrophila in an Alcohol Abuser.

Abstract

A 69-year-old alcoholic manwith pneumonia and sepsis due to Aeromonashydrophila is presented. He died of suffocation by a copious amount of hemoptysis six hours after his first symptoms of abdominal pain, diarrhea and dyspnea. Aeromonas hydrophila was isolated from blood and bronchial secretion. A fulminant form of pneumonia could develop in patients with predisposing underlying conditions such as alcoholism with chronic hepatitis and diabetes mellitus. Aeromonas hydrophila pneumonia may be characterized by hemoptysis and rapid clinical deterioration with a high mortality rate. (Internal Medicine 35: 410-412, 1996)

Aeromonas spp. clinical microbiology and disease

“…61e63 However, such cases are extremely rare with Aeromonas linked pneumonia and lung abscesses usually as a result of an underlying medical condition such as cardiovascular disease or alcohol abuse. 64 …”

Prospective Nationwide Study of Aeromonas Infections in France

“…on May 11, 2018 by guest http://jcm.asm.org/ respiratory tract pathogen, although rarely encountered (2,11,13,15,25,26,28,33), our cases with mixed culture were categorized as "possible infection" to better reflect the RTI frequency. Finally, four specific infections included ocular infection, hepatobiliary infection, urinary tract infection, and peritonitis with mesenteric ulcer perforation, all occasionally reported (4,5,13,27).…”

Pathogenic Aeromonas hydrophila Serogroup O:14 and O:81 Strains with an S Layer

“…The distribution of the surface array protein genes of A. hydrophila TF7 and A. salmonicida A450 among our autoagglutinating and S-layer-positive strains was assessed by colony hybridization. The most striking finding was the lack of hybridization with the structural genes for the Aeromonas S layers, vapA (3) and ahsA (45), in our O:14 and O:81 A. hydrophila strains, although these isolates possessed an S layer ( Table 2). As expected, colony hybridization assays detected the presence of the ahsA and vapA genes in A. hydrophila TF7 and A. salmonicida A450 ( Table 2).…”

“…A. hydrophila has been increasingly reported as one of the most common Aeromonas species associated with human intestinal disease (1,24,36) and systemic illnesses in immunocompromised patients (14,15,45). One group of A. hydrophila strains with high virulence for trout was reported (8,32).…”
