Vibrio alginolyticusAssociated Chronic Myringitis Acquired in Mediterranean Waters of Turkey

Abstract

Vibrio alginolyticus was originally classified as biotype 2 of Vibrio parahaemolyticus. Most clinical isolates are recovered from superficial wounds or the external ear infections. V. alginolyticus is acknowledged to be nearly nonpathogenic in humans. The reason for presence of V. alginolyticus's virulence is uncertain. We describe a chronic myringitis case in a 47-year-old female due to V. alginolyticus. According to her anamnesis, it was detected that she had sea bathing history in Mugla Coast in Turkey. Pure isolation of V. alginolyticus was obtained from external auditory canal's culture. Investigation and antimicrobial susceptibility of the isolate were performed by the automatized BD Phoenix system and Kirby-Bauer disk diffusion method, respectively. The bacteria were sensitive to all antibiotics. This case was presented to pay attention to Vibrio alginolyticus infections.

Reduced redox‐dependent mechanism and glucose‐mediated reversal in gentamicin‐resistant Vibrio alginolyticus

“…Vibrio alginolyticus was previously designated as a biotype 2 of V . parahaemolyticus (Citil et al ., ), and several V . alginolyticus strains carry virulence genes derived from pathogenic V .…”

“…Vibrio alginolyticus is an important etiological factor of vibriosis, presenting opportunistic infections to humans ingested with raw seafood as well as causing severe infections in aquaculture (Sasikala and Srinivasan, 2016;Economopoulou et al, 2017;Jacobs et al, 2017;Yang et al, 2018c). Vibrio alginolyticus was previously designated as a biotype 2 of V. parahaemolyticus (Citil et al, 2015), and several V. alginolyticus strains carry virulence genes derived from pathogenic V. parahaemolyticus and V. cholerae strains (Hernández-Robles et al, 2016). Recently, antibiotic-resistant V. alginolyticus has been found at a high frequency around all coastal areas worldwide (Sperling et al, 2015;Zavala-Norzagaray et al, 2015), especially in Asia (Tra et al, 2016).…”

Fast, simple and highly specific molecular detection of Vibrio alginolyticus pathogenic strains using a visualized isothermal amplification method

“…V. alginolyticus is a Gram-negative, rod-shaped, flagellar bacterium that has halophilic features and widely exists in ocean and estuarine areas [1][2][3]. V. alginolyticus is considered one of the most harmful Vibrio species and is pathogenic to both humans and aquatic animals [2,4]. In humans, soft tissues, the ear, and superficial wounds are easily invaded by V. alginolyticus when exposed to contaminated seawater [4].…”

In humans, soft tissues, the ear, and superficial wounds are easily invaded by V. alginolyticus when exposed to contaminated seawater [4]. Clinical symptoms include chronic diarrhea, otitis and wound infection [5,6].…”

NaCl promotes antibiotic resistance by reducing redox states in Vibrio alginolyticus

“…V. alginolyticus is among the species commonly known to cause human illnesses and leads to great losses in aquaculture (Adams and Boopathy, 2013;Economopoulou et al, 2017). V. alginolyticus was originally classified as biotype 2 of V. parahaemolyticus (Citil et al, 2015) and is considered a slightly halophilic marine bacterium (Unemoto and Hayashi, 1979). The bacterium grows in NaCl concentrations ranging from 0.2 to 1.5 M and maintains their total internal solute concentration higher than the external medium (Unemoto and Hayashi, 1979).…”
