What is Psychrobacter sp?

Psychrobacter is a genus of mostly psychrotrophic cocco-bacilli, Gram-negative, catalase, and oxidase-positive species. A common species found in milk, Psychrobacter immobilis, are aerobic, but some strains can also be anaerobic. Similarly, Acinetobacter are Gram-negative, oxidase-negative rods but strict aerobes.

Where is Psychrobacter found?

Psychrobacter spp. usually live in deep sea environments and cold habitats, such as Antarctic ice or Siberian permafrost. Members of the Psychrobacter genus are small Gram-negative coccobacilli.

Can Psychrobacter phenylpyruvicus cause infection?

Psychrobacter species rarely cause infections in human. We reported herein a 62-year-old cirrhotic patient who presented with fever and diarrhoea after the consumption of raw geoduck clam. Blood culture grew Psychrobacter phenylpyruvicus which was sensitive to most anti-microbial agents.

Can humans get Psychrobacter phenylpyruvicus from raw geoduck clam?

Blood culture grew Psychrobacter phenylpyruvicus which was sensitive to most anti-microbial agents. The patient responded promptly to intravenous antibiotics. This is the first report of human infection with this unusual organism which illustrates the potential health hazards of eating raw geoduck clam in patients with advanced liver disease.

Is Psychrobacter sanguinis susceptible to penicillin resistance?

P. sanguinis has previously been described as broadly susceptible ( 7 ); however, Psychrobacter spp. have displayed penicillin resistance ( 1 ). We describe a case of P. sanguinis infection in a healthy person after wound exposure to squid bait and seawater of the Pacific Northwest Coast.

What is Psychrobacter spp?

Psychrobacter spp. are opportunistic pathogens found in a wide range of environments. Clinicians should be aware of Psychrobacter spp. and perform 16S rRNA sequencing if this pathogen is suspected.
