SINGAPORE \u2013 Every pet owner dreads it when a dog\u2019s itchy skin or a cat\u2019s ear irritation snowballs into costly vet visits and a 14-day regimen of strong antibiotics.<\/p>\n
Not only is it expensive, but \u201cantibiotics can also breed resistance and create superbugs, making it difficult to get rid of the infection\u201d, said biotechnologist Avinanda Banerjee.<\/p>\n
Avinanda, who co-founded Healbac, a deep-tech biotech spin-off from A*STAR, said antimicrobial peptides are the solution.<\/p>\n
Officially launched as a private company in November 2025, Healbac has developed \u201cstem-cell-derived and nature-inspired antimicrobial peptides designed to kill germs\u201d.<\/p>\n
But the peptides were not originally intended as a treatment for pets.<\/p>\n
\u201cThe intention was to design the peptides to replace chemical preservatives such as sodium nitrite in processed meats, deli items and cold-chain foods,\u201d said Avinanda, who was part of the first cohort of Activate Global Fellows \u2013 Singapore, a national fellowship hosted by Nanyang Technological University.<\/p>\n
The fellowship was set up to support promising science and technology ventures in becoming globally competitive companies.<\/p>\n
She received up to $200,000 in stipend support and funding for business development and research and development, alongside mentorship and two immersion trips to the US.<\/p>\n
In October, the group travelled to San Francisco and Silicon Valley, where they met potential customers, investors and industry partners.<\/p>\n
Avinanda said that although sodium nitrite in foods does not directly cause cancer, it can be converted into cancer-causing compounds inside the body or during high-heat cooking.<\/p>\n
\u201cSo food manufacturers and regulators are looking for safe alternatives that do not carry these health risks, yet are able to perform equally well as the chemical preservatives currently used,\u201d she added.<\/p>\n
Almost 73% of antibiotics are used in farm animals. The unnecessary use of antibiotics to prevent microbial spoilage also contributes to antimicrobial resistance (AMR), so the world needs to look for alternatives, she explained.<\/p>\n
\u201cAt Healbac, we understand the problem, and we are trying to solve it using nature\u2019s own selection process. Otherwise, we will be seeing a limb lost to diabetes every 20 seconds in the next 20 years because infections are not getting healed,\u201d she added.<\/p>\n
Avinanda was working with a team of scientists at A*STAR when they first discovered antimicrobial peptides, which are short chains of amino acids modelled on natural defence molecules produced by plants, animals, insects, amphibians and microorganisms.<\/p>\n
They help address AMR in several ways: by attaching themselves to bacterial cell membranes and causing them to burst; attacking multiple structural components simultaneously, making it harder for pathogens to evolve ways to escape them; and shutting down microscopic pumps that drug-resistant strains of bacteria use to actively reject conventional antibiotics.<\/p>\n Avinanda Banerjee is acting chief executive and business lead of Healbac, which develops antimicrobial peptides inspired by nature and derived from stem cells to kill germs.<\/p>\n PHOTO: ACTIVATE GLOBAL FELLOWS – SINGAPORE, NTU<\/p>\n<\/figcaption><\/figure>\n \u201cWe co-cultured human cells with pathogenic bacteria in the laboratory and, as a response, these human cells released defence molecules to protect themselves. We isolated those molecules and identified the antimicrobial peptides… With further chemical modifications, we obtained peptides that were active against bacteria,\u201d Avinanda said.<\/p>\n Healbac was set up to translate stem-cell and peptide research into commercial alternatives to conventional antibiotics and synthetic food preservatives, with the aim of tackling AMR and reducing reliance on potentially harmful food additives.<\/p>\n \u201cWhatever we are seeing is just the tip of the iceberg. If we do not come up with a solution, in 30 years, millions of lives, healthcare systems and food security will be affected,\u201d she said.<\/p>\n However, Healbac is now validating potential applications of its antimicrobial peptides in wound and skincare, focusing on the gap before vets prescribe antibiotics to treat infections.<\/p>\n \u201cWhen an infection happens to a pet dog or a cat, they are often rushed to the vet and the first option they get is an antiseptic. Antiseptics are good for cleaning wounds at the site of the infection, but they do not cure the infection.<\/p>\n \u201cSo the next option vets turn to is a course of antibiotics. But the dogs or cats return in two to three months when the infection is back,\u201d Avinanda said.<\/p>\n With vets seeking topical treatments as alternatives to systemic antibiotics, she said what Healbac has developed from the body\u2019s \u201cnatural defence mechanism would work wonders\u201d.<\/p>\n When an itch becomes more than a nuisance, it can signal a more serious medical issue in dogs. Treating any resulting infections with antibiotics can contribute to drug resistance and create superbugs.<\/p>\n PHOTO: COURTESY OF KENNETH TONG<\/p>\n<\/figcaption><\/figure>\n She said Healbac would need to validate the use of the product before it can be commercialised.<\/p>\n \u201cAnd if we were to commercialise it, there would be multiple benefits at different levels. It would be not only for humans but also for other applications. That was when we started targeting veterinary therapeutics,\u201d she said.<\/p>\n The first \u201cpatient\u201d to be treated with Healbac\u2019s peptide was a French bulldog, whose skin infection cleared within three days of using the topical cream.<\/p>\n Currently, the start-up is working with six vet clinics in Singapore to test the peptide\u2019s effectiveness in treating infections in cats and dogs.<\/p>\n \u201cThis is where we can position our peptide-based, topical, antimicrobial solution for vet therapeutics. We are still generating the clinical database to make sure that whatever we are building has an actual effect and not just (relying) on lab-based data,\u201d Avinanda said.<\/p>\n \u201cOnce successful, we need to understand how we can position our product \u2013 whether it should be sold only at clinics or it should be an over-the-counter product.\u201d<\/p>\n<\/div>\n SINGAPORE \u2013 Every pet owner dreads it when a dog\u2019s itchy skin or a cat\u2019s ear irritation snowballs into costly vet visits and a 14-day…<\/p>\n","protected":false},"author":1,"featured_media":99379,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"","fifu_image_alt":"","footnotes":""},"categories":[2611],"tags":[],"class_list":["post-99378","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-buzz-headlines","wpcat-2611-id"],"_links":{"self":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/99378","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=99378"}],"version-history":[{"count":0,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/posts\/99378\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=\/wp\/v2\/media\/99379"}],"wp:attachment":[{"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=99378"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=99378"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sgbuzz.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=99378"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}<\/picture><\/div>
