in the urine of a patient with chronic prostatitis, renal microlithiasis and acute cystitis we found the ciliate protozoa colpoda spp . , both in vegetative and cystic form. the entry point was most likely the urinary tract. keeping in mind that only four more cases of colpoda spp . existent in human urine have already been described, and that in the case of our patient the ciliate was present ...

Protozoa are eukaryotic cells distributed worldwide in nature and are receiving increasing attention as reservoirs and potential vectors for the transmission of pathogenic bacteria. In the environment, on the other hand, many genera of the protozoa are human and animal pathogens. Only limited information is available on these organisms in developing countries and so far no information on their ...

Studies on Legionella show a continuum from environment to human disease. Legionellosis is caused by Legionella species acquired from environmental sources, principally water sources such as cooling towers, where Legionella grows intracellularly in protozoa within biofilms. Aquatic biofilms, which are widespread not only in nature, but also in medical and dental devices, are ecological niches i...

BACKGROUND Intestinal parasites are still a serious public health problem in the world, especially in developing countries. This study aimed to assess the prevalence of intestinal protozoa infections and associated risk factors among schoolchildren in Sanandaj City, Iran. METHODS This cross-sectional study involving 400 schoolchildren was carried out in 2015. Each student was selected using s...

BACKGROUND The repertoire of free-living protozoa in contact lens solutions is poorly known despite the fact that such protozoa may act as direct pathogens and may harbor intra-cellular pathogens. METHODS Between 2009 and 2014, the contact lens solutions collected from patients presenting at our Ophthalmology Department for clinically suspected keratitis, were cultured on non-nutrient agar ex...

Caryospora simplex is reported for the first time from the feces of a captive female Kaznakov's viper (Vipera kaznakovi) in Albuquerque, New Mexico (USA). Coccidian meronts and gamonts were observed in the intestinal epithelial cells of another female Kaznakov's viper that died in October 1993.
