Objective. To determine the Cryptosporidium spp. infection frequency by using Ziehl-Neelsen and Auramine stains on samples obtained from diarrheic calves from milking farms of the Valdivia province. To compare both diagnostic tests and to determine the geospatial distribution of the infections caused by this protozoan. Materials and methods. 221 fecal samples of diarrheic calves of 24 milking f...

Cryptosporidium parasite has gained an attention as an emerging pathogen in the last few decades. It is a zoonotic and is transmitted via the fecal-oral route; this has been implicated as one of the more important opportunistic infections in patients with Acquired immune deficiency syndrome. The results showed the presence of Cryptosporidium oocyst in fecal of sheep (11.1 and 22.2%), goats (15....

AIMS To evaluate the use of a gene amplification and hybridisation method for detecting mycobacterial nucleic acid as a possible diagnostic method for cutaneous tuberculosis infection. METHODS Biopsy specimens from 20 patients with various skin conditions of possible tuberculous aetiology were studied. Six patients had ulcerative nodules, seven lupiform lesions, two non-necrotic granulomas, o...

faecal samples from 291 dairy calves from 10 dairy herds in kerman were examined to investigate theprevalence of cryptosporidium infection. cryptosporidium spp. oocysts were identified by using themodified ziehl-neelsen staining technique in 63 (21.65%) calves. calves were grouped according to theirage as follows:

causes human intestinal cyclosporiasis. It is more common in the immunocompromised patients and mainly seen people living with HIV/AIDS (PLHA), post-renal transplant (PRT) children (IC). Diagnostic microscopy for oocysts of parasite less sensitive, requiring examination multiple stool samples. Here we developed a new single run polymerase chain reaction (PCR) assay detection it was used to know...

Wastewater treatment is a widely used health protection measure that can be applied to control the transmission of wastewater-related infectious diseases communities exposed wastewater. This study determined efficiency three full-scale constructed wetlands (CWs) in removing pathogenic parasites and fecal coliform (FC) bacteria from samples were collected CW systems located Dar es Salaam Iringa ...

Cryptosporidium parvum is a zoonotic protozoan parasite with a wide range of vertebrate hosts. The present study was conducted to determine the prevalence of Cryptosporidium parvum in urban and rural dogs of the Ahvaz area. Faecal samples were collected randomly from 93 dogs between May 2005 and September 2007. The studied dogs were divided into two groups (urban and rural) and based on age int...
