The genus Sarcocystis is not usually considered as an important enteric pathogen in immune compromised patients. It might be expected that species for which humans are the final host (Sarcocystis hominis and Sarcocystis suihominis as well as possibly others) would be encountered increasingly often in immunodeficient persons. This study aimed to address how to detect and differentiate Sarcocysti...

Despite recent advances in diagnostic technology, microscopic examination of stool specimens remains central to the diagnosis of most pathogenic intestinal protozoa. Microscopy is, however, labor-intensive and requires a skilled technologist. New, highly sensitive diagnostic methods have been developed for protozoa endemic to developed countries, including Giardia lamblia (syn. G. intestinalis/...

It has been hypothesized that chronic renal failure (CRF) predisposes patients to infection with intestinal protozoa. We tested this hypothesis with a matched case-control study to determine the prevalence of these protozoa and their diarrhea associated symptoms among 50 patients with CRF (cases) from Taif, western Saudi Arabia. Fifty diarrheal patients without CRF were recruited in the study a...

The demand for tilapia fishing goods has recently expanded on a national scale. One of the difficulties this fish farming operation encountered was parasite-caused illness. aims study were to explore parasites in (Oreochromis niloticus) from local seller Dramaga, Bogor, West Java. A total 14 sampled, with an average length 22 cm and body weight 195 grams. Fish gills, pectoral fins, caudal tail ...

Among the micro-organisms that may affect the respiratory apparatus are the protozoa. The diseases they may give rise to constitute a relatively uncommon group of respiratory ailments with, in the majority of cases, an underlying clinical situation corresponding to states of suppressed immunity (AIDS, transplants, malign haemopathies, corticotherapy, etc.). Other factors, such as visits to ende...

The International Centre for Diarrhoeal Disease Research, Bangladesh, is a major center for research into diarrheal diseases. The center treats more than 100,000 patients a year. To obtain useful information representative of all patients, a surveillance system in which a 4% systematic sample of all patients is studied in detail, including etiological agents of diarrhea, was installed in Octobe...
