serovar Hvittingfoss, a member of the non-typhoidal group, is an important foodborne serovar most frequently identified in regions (Australia, Belgium, and the United States) with active surveillance systems. This serovar has been implicated in outbreaks of foodborne illness. Soft cheese, crab cocktail, beef, and rock melon are commonly involved in these outbreaks. Although the definitive host of this serovar is not yet established, Hvittingfoss can be found in wild animals (Feral pigs), bird populations (Bar-tailed godwit, Plumed whistling ducks, White-naped crane, and Sharp-tailed sandpiper), and domestic birds like chickens. We report the first case of serovar Hvittingfoss causing acute gastroenteritis in a 52-year-old male labourer and agriculturist from a rural area of Mysuru, South India. This is the first documented case of Hvittingfoss causing acute gastroenteritis in India. While non-typhoidal infections typically resolve on their own, they can be particularly dangerous for certain demographics, such as children, the elderly, and those with compromised immune systems. Therefore, studying the different serotypes of these infections in both clinical and subclinical cases is crucial for targeting effective surveillance, hygiene practises, and food safety measures that can mitigate their impact on public health.
血清型Hvittingfoss是非伤寒菌群的成员，是一种重要的食源性血清型，在有主动监测系统的地区（澳大利亚、比利时和美国）最为常见。该血清型与食源性疾病暴发有关。软奶酪、蟹肉鸡尾酒、牛肉和甜瓜通常与这些暴发有关。虽然该血清型的最终宿主尚未确定，但在野生动物（野猪）、鸟类种群（斑尾塍鹬、羽冠啸鸭、白枕鹤和尖尾沙锥）以及鸡等家禽中都能发现Hvittingfoss。我们报告了首例血清型Hvittingfoss导致一名来自印度南部迈索尔农村地区的52岁男性劳工和农民患急性肠胃炎的病例。这是印度首例有记录的Hvittingfoss导致急性肠胃炎的病例。虽然非伤寒感染通常会自行痊愈，但对某些人群，如儿童、老年人和免疫系统受损者来说，可能特别危险。因此，在临床和亚临床病例中研究这些感染的不同血清型对于确定有效的监测、卫生习惯和食品安全措施至关重要，这些措施可以减轻它们对公众健康的影响。
