It then spread through his bloodstream and into both legs.<\/p>\n<p>&#8220;Shewanella species are found in aquatic environments and can cause skin and soft tissue infections, bloodstream infections and other serious illnesses,&#8221; they said.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/nz\/wp-content\/uploads\/2026\/06\/shewanella-GVVY6XIODZFL7J56VKLWBPRI6Y.jpg\" alt=\"A 3D-rendering of Shewanella, which are rod-shaped bacteria found in marine environments.\" width=\"800\" height=\"450\" loading=\"lazy\"\/><\/p>\n<p class=\"ImageMetadata__MetadataParagraph-sc-hi5x8q-0 cWTYyG image-metadata\">A 3D-rendering of Shewanella, which are rod-shaped bacteria found in marine environments. (Source: istock.com)<\/p>\n<p>Documented infections of this bacterium are rare in New Zealand.<\/p>\n<p>Two local cases<\/p>\n<p>According to the report, only two locally acquired Shewanella infections have previously been described in New Zealand medical literature. <\/p>\n<p>One involved a fisherman in the Bay of Plenty who developed cellulitis after sustaining cuts from a fishing bin, while another followed freshwater exposure in the Rotorua region.<\/p>\n<p>The patient responded to antibiotic treatment and was discharged 10 days later.<\/p>\n<p>However, his recovery was complicated by underlying diabetes and poor wound healing. <\/p>\n<p>Later that year, he developed a severe bone infection in his left foot and ankle, ultimately requiring a below-knee amputation. Samples taken during surgery again identified Shewanella algae among the organisms present.<\/p>\n<p>The authors of the report said the case was a reminder for marine bacteria to be considered in patients with severe infections after overseas travel.<\/p>\n<p>They also urged clinicians not to dismiss cellulitis simply because both legs are affected, especially when a patient shows signs of serious infection.<\/p>\n<p class=\"text-greyDarkFaded\">The morning&#8217;s headlines in 90 seconds, including Trump flipflops on Iran attack, and a shark attack caught on camera.
