Under diagnosis of intestinal schistosomiasis in a referral hospital, North Ethiopia
BMC research notes, 2018Co-Authors: Megbaru Alemu, Eyob Zigta, Awoke DerbieAbstract:The present cross-sectional study was aimed at determining the magnitude of under diagnosis of intestinal schistosomiasis among patients requested for routine ova/Parasite Examination at Ayder referral hospital. A total of 280 stool samples were collected and only 5% of the patients were positive for ova of Schistosoma mansoni in the routine direct wet mount microscopy. On the other hand, 12.5% of the patients were positive for ova Schistosoma mansoni when the stool samples were processed by either Kato Kat or formol ether concentration techniques. Moderate test agreement (κ = 0.48) was recorded for wet mount. Formol-ether concentration (κ = 0.89) and Kato-Katz (κ = 0.92) showed excellent agreements with the ‘Gold’ standard. Direct wet mount technique exhibited the poorest sensitivity (35%) of detection of ova of Schistosoma mansoni. Hence, the Kato-Katz technique should be implemented in parallel with the direct wet mount microscopy for Schistosoma mansoni presumptive patients.

comparison of the triage micro Parasite panel and microscopy for the detection of entamoeba histolytica entamoeba dispar giardia lamblia and cryptosporidium parvum in stool samples collected in kenya
Journal of Tropical Medicine, 2012Co-Authors: Brett Swierczewski, Elizabeth Odundo, Janet Ndonye, Ronald Kirera, Cliff P Odhiambo, Edwin V OaksAbstract:Entamoeba histolytica, Giardia lamblia, and Cryptosporidium parvum are three of the most important parasitic causes of acute diarrhea worldwide. Laboratory diagnosis of these Parasites is usually done by ova and Parasite Examination (O&P Examination) via microscopy. The sensitivity and specificity of O&P Examination varies among laboratories and can be labor intensive and time consuming. The Triage Micro Parasite Panel (BioSite, San Diego, California) is an enzyme immunoassay kit that can detect E. histolytica/E. dispar, G. lamblia, and C. parvum simultaneously using fresh or frozen stool. The present study evaluated the Triage Micro Parasite Panel in detecting E. histolytica/E. dispar, G. lamblia, and C. parvum compared to O&P Examination in 266 stool samples collected at medical facilities in Kenya. The sensitivity and specificity results for the Triage Micro Parasite Panel were: for E. histolytica/E. dispar: 100%, 100%, G. lamblia: 100%, 100% and C. parvum: 73%, 100%. There was no evidence of cross reactivity using the kit with other Parasites identified in the stool specimens. These results indicate that the Triage Micro Parasite Panel is a highly sensitive kit that can be used for screening purposes in large scale studies or outbreak investigations or as a possible alternative to O&P Examination.

Copepods associated with a perirectal abscess and copepod pseudo-outbreaks in stools for ova and Parasite Examinations.
Diagnostic microbiology and infectious disease, 1992Co-Authors: Kenneth G. Van Horn, Joseph S. Tatz, Leonard Newman, Gary P. WormserAbstract:Abstract We observed copepods, an intermediate host for several human Parasites, in material obtained from a perirectal abscess of a 22-year-old man with Crohn's disease. We subsequently noted copepod “outbreaks” in stool specimens submitted for ova and Parasite Examination. Copepods in the hospital tap water supply were the source for one “outbreak.”
