Cryptosporidiosis and giardiasis are recognized as significant enteric diseases due to their long-term health effects in humans and their economic impact in agriculture and medical care. Molecular analysis is essential to identify species and genotypes causing these infectious diseases and provides a potential tool for monitoring. This study uses information on species and genetic variants to g...

A multilocus fragment typing approach including eleven variable-number tandem-repeat (VNTR) loci and the GP60 gene was used to investigate the intra-farm and intra-host genetic diversity of Cryptosporidium parvum in sheep farms in a confined area in northeastern Spain. Genomic DNA samples of 113 C. parvum isolates from diarrheic pre-weaned lambs collected in 49 meat-type sheep farms were analyz...

In the present study, we analyzed genetic variation in Cryptosporidium species from humans (n = 62) with clinical cryptosporidiosis in South Australia. Sequence variation was assessed in regions within the small subunit of nuclear rRNA (p-SSU), the 70-kDa heat shock protein (p-hsp70), and the 60-kDa glycoprotein (p-gp60) genes by employing single-strand conformation polymorphism analysis and se...

Cryptosporidium parasite is a cause of diarrhea in humans and other cold and endotherm animals that have been widely distributed throughout the world. This study aimed to determine the genetic diversity of Cryptosporidium in children with diarrhea using the GP60 gene by Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP) method. In this study, stool specimens were coll...

The prevalence of Cryptosporidium and microsporidia in feral horses, which have minimal contact with livestock and humans, is not currently known. We report the findings of a study on Cryptosporidium and microsporidia in 34 Mustangs and 50 Chincoteague ponies in the USA. Fecal samples were screened for presence of Cryptosporidium spp. by analysis of the small-subunit rRNA (SSU) and 60-kDa glyco...

Cryptosporidium chipmunk genotype I is an emerging zoonotic pathogen in humans. The lack of subtyping tools makes it impossible to determine the role of zoonotic transmission in epidemiology. To identify potential subtyping markers, we sequenced the genome of a human chipmunk genotype I isolate. Altogether, 9,509,783 bp of assembled sequences in 853 contigs were obtained, with an N50 of 117,886...

Cryptosporidiosis is a major cause of diarrhoeal illness among African children, and associated with childhood mortality, malnutrition, cognitive development growth retardation. Cryptosporidium hominis the dominant pathogen in Africa, genotyping at glycoprotein 60 ( gp60 ) gene has revealed complex distribution different subtypes across this continent. However, comprehensive exploration metapop...

The main goal of this investigation was to develop and test a new method of treatment for human hepatocellular carcinoma (HCC). We present a method of carbon nanotube-enhanced laser thermal ablation of HepG2 cells (human hepatocellular liver carcinoma cell line) based on a simple multiwalled carbon nanotube (MWCNT) carrier system, such as human serum albumin (HSA), and demonstrate its selective...

Cryptosporidium is a protozoan parasite of humans and animals and has a worldwide distribution. The parasite has a unique epidemiology in Middle Eastern countries where the IId subtype family of Cryptosporidium parvum dominates. However, there has been no information on Cryptosporidium species in Yemen. Thus, this study was conducted in Yemen to examine the distribution of Cryptosporidium speci...

The objective of this study was to determine the prevalence, species and subtypes of Cryptosporidium infecting yaks in the Qinghai Province of Northwestern China. The prevalence of Cryptosporidium spp. was detected by microscopy and nested-PCR. A total of 586 fecal samples were collected from yaks in 6 counties, of which 142 (24.2%) samples tested positive for Cryptosporidium. The small subunit...
