  • PRESENTING CONCERNS A 63-year-old Vietnamese man, retired worker, underwent travel health examination in our hospital. Physical examination showed that his height was 159 cm and weight was 41 kg.[journals.lww.com]
Chronic Infection
  • We believe that an acute IB infection through fecal-oral transmission may progress to chronic infection of the hepatobiliary system, leading to biliary obstruction and jaundice.[ncbi.nlm.nih.gov]
Cervical Lymphadenopathy
  • In August, 1974, he noticed cervical lymphadenopathy for the first time and it was diagnosed as undifferentiated type of malignant lymphoma. He died in December, 1974.[ncbi.nlm.nih.gov]
Chronic Watery Diarrhea
  • The infection was associated with chronic watery diarrhea and weight loss that was clinically indistinguishable from disease caused by the related coccidia cryptosporidium.[ncbi.nlm.nih.gov]
  • Sx included chronic watery diarrhea & weight loss. In all pts with isosporiasis, diarrhea stopped within2 days of beginning oral TMP-SMX. Recurrent symptomatic isosporiasis developed in 47%, but responded promptly to re-initiation of therapy.[hopkinsguides.com]
  • We believe that an acute IB infection through fecal-oral transmission may progress to chronic infection of the hepatobiliary system, leading to biliary obstruction and jaundice.[ncbi.nlm.nih.gov]
  • The study medications were generally well tolerated but had to be discontinued in the cases of two patients because of severe pruritus.[ncbi.nlm.nih.gov]
  • […] diffuse dilatation of the biliary tree; the common hepatic and pancreatic duct diameters increased to 1.86 cm and 0.61 cm, respectively.Endoscopic retrograde cholangiopancreatography was performed and a 10-Fr model plastic biliary stent was inserted and flushed[ncbi.nlm.nih.gov]
  • When dark green thick bile drained out from the stent, we placed the endoscopic catheter insert to the orifice of the stent and flushed with 20 cc normal saline through the endoscopic catheter.[journals.lww.com]
  • We suggest that Isospora belli may be a sexually transmitted pathogen which should be considered in the diagnosis of homosexual patients with diarrhea.[ncbi.nlm.nih.gov]
  • All cases were followed for 15 months, without findings suggestive of active biliary disease that suggests immunocompetant individuals don’t have ongoing problems with infection. Legua P, Seas C. Cystoisospora and cyclospora.[hopkinsguides.com]
  • We suggest that treatment with TMP-SMZ should be initiated and continued for a prolonged period of time in immunocompromised patients with I. belli diarrhea. 1.[ncbi.nlm.nih.gov]
  • Figure 3 Hematoxylin and eosin stained section of duodenal mucosa with numerous sub-nuclear cytoplasmic inclusions (arrows), suggestive of protozoal infection (A—40 and B—200 ).[academic.oup.com]


  • Tests for HTLV-1 and 2 antibody must be part of the routine workup, especially in individuals living in developed countries as it can cause immunocompromise similar to HIV.[ncbi.nlm.nih.gov]


  • The challenge for emergency physicians is to swiftly and accurately differentiate disease etiology and institute prompt treatment.[ncbi.nlm.nih.gov]
  • OBJECTIVE: To compare 1 week of trimethoprim-sulfamethoxazole treatment and 1 week of ciprofloxacin treatment in HIV-infected patients with chronic diarrhea caused by I. belli and C. cayetanensis. DESIGN: Randomized, controlled trial.[ncbi.nlm.nih.gov]
  • Patients undergoing such immunosuppressive treatment are more susceptible for infectious pathogens.[ncbi.nlm.nih.gov]
  • Although Entamoeba histolytica and other nonpathogenic enteric protozoa were observed along with Isospora belli in this patient's stool specimens, they were promptly eradicated after metronidazole (flagyl) treatment.[ncbi.nlm.nih.gov]
  • Treatment is based on trimethoprim-sulfamethoxazole. In 2006 we performed an isolated intestinal transplantation in a patient with ultra-short bowel syndrome.[ncbi.nlm.nih.gov]


  • Abstract The study of 11 cases of isosporiasis (Isospora belli) shows that this opportunistic coccidia, alone or with Cryptosporidium, causes severe prolonged diarrhoea which worsens the prognosis and evolution of AIDS patients.[unboundmedicine.com]


  • The challenge for emergency physicians is to swiftly and accurately differentiate disease etiology and institute prompt treatment.[ncbi.nlm.nih.gov]
  • Each part surveys individual infections caused not only by well-known etiologic agents, but also by new and emerging species often taxonomically closely related to a major disea- producing microorganism and until recently not considered to be human pathogens[books.google.it]
  • 抄録 The emerging protozoan parasites Cryptosporidium, Cyclospora cayetanensis and Isospora belli have altered the etiological spectrum of diarrhea.[jstage.jst.go.jp]
  • We cannot determine the etiology of the diarrhea symptoms among our study population since no other bacterial or virus results were at hand.[omicsonline.org]
  • […] lymphoma and thymoma [1] , [2] , [3] , [4] and post transplant patients. [5] , [6] , [7] Stool samples from the immunosuppressed patients and children received in the Department of Medical Parasitology from year 2008 to 2012 for investigation of parasitic etiology[ijpmonline.org]


  • The pathology, epidemiology, clinical findings and therapy of human intestinal infection with Isospora belli are also addressed.[ncbi.nlm.nih.gov]
  • The simple fecal sample collection procedure, the high-throughput potential, and the possibility of quantification makes the I. belli real-time PCR assay a powerful diagnostic tool for epidemiologic studies with possibilities for extension to other helminthes[ncbi.nlm.nih.gov]
  • Each chapter of this monograph covers the history, morphology, life cycle, global epidemiology, risk factors, immunology, symptoms, diagnosis, treatment and perspectives of control for each relevant protozoan parasite that can be found in contaminated[books.google.it]
