The advances in medical technology in recent years has brought highly progressive developments into diagnostic microbiology. Therefore, it is not feasible to enumerate all the recent advances in clinical microbiology; attempts are made here to discuss only those developments of clinical relevance. The two major aspects of advances in microbiology are the discovery or isolation of new pathogens and the breakthrough in new technology. Of equal importance are some known pathogens which have taken on new roles either as the cause of a new clinical syndrome or as the leading cause of a known clinical syndrome.

“…Humans are an accidental host of the parasite. In humans, Anisakis have been found in the mucosa of the stomach and intestine and less commonly in the omentum, liver, pancreas, and lung [3][4][5]. Clinical manifestations of enteric anisakiasis include colicky abdominal pain, nausea, and vomiting [6].…”

Anisakiasis of the gastrointestinal tract is caused by the consumption of raw or undercooked seafood infected with Anisakis larvae. Penetration of Anisakis larvae into the gastrointestinal mucosa leads to severe epigastric pain, nausea, and vomiting, usually within hours of ingestion of the parasite. Suspicion for gastrointestinal Anisakiasis should be raised in patients with a compatible dietary history. Definitive diagnosis can be made by direct visualization of larvae via endoscopic examination. Although symptoms are self-limiting, the removal of larvae by gastroscopy can hasten relief of symptoms. There are a large number of cases of gastric anisakiasis reported from Japan, Korea, and Western Europe, where it is customary to consume raw fish. Cases reported from the United States are less common, and given the nonspecific symptoms of anisakiasis, the diagnosis can be missed. We report a patient who presented with gastroesophageal reflux disease like symptoms that started after ingesting raw fish. He was found by esophagogastroduodenoscopy to have white, filiform worms penetrating into the wall of his stomach, consistent with a diagnosis of gastric anisakiasis.

Anisakiasis

Anisakiasis is a zoonotic disease caused by the ingestion of larval nematodes in raw seafood dishes such as sushi, sashimi, ceviche, and pickled herring. Symptoms of anisakiasis include abdominal pain, nausea, vomiting, and diarrhea. Because symptoms are vague, this disease is often misdiagnosed as appendicitis, acute abdomen, stomach ulcers, or ileitis. Endoscopic examination with biopsy forceps has facilitated the diagnosis of gastric anisakiasis. Worms can be removed and identified, and a definitive diagnosis can be made. Patients generally recover with no further evidence of disease. Worms can become invasive, however, and migrate beyond the stomach, penetrating the intestine, omentum, liver, pancreas, and probably the lungs. Surgery is often necessary for treatment of invasive anisakiasis. With the increase in popularity of eating lightly cooked or raw fish dishes, the number of cases of anisakiasis may be expected to increase.
