Parasites & Vectors 20/04/17 Cryptosporidium and Giardia in Africa: current and future challenges.

Genotyping of Cryptosporidium species in Africa have identified at least 13 species and genotypes in humans including C. hominis, C. parvum, C. meleagridis, C. ubiquitum, C. viatorum, C. andersoni, C. bovis, C. canis, C. cuniculus, C. felis, C. muris, C. suis and C. xiaoi [23, 25, 26, 86, 97, 101, 102, 115, 139, 140, 141, 142] (see Table 2).

Parasites & Vectors 20/04/17 Cryptosporidium and Giardia in Africa: current and future challenges

Cryptosporidium hominis and C. parvum are the main species infecting humans [6, 143, 144, 145]. Out of the 56 molecular studies in African countries analysed, C. hominis was the most prevalent (2.4–100%) Cryptosporidium species in humans in 38 of the studies followed by C. parvum (3.0–100%) in 13 studies and C. meleagridis (75%) in one study, C. viatorum and C. hominis (40% each) in one study and a single species of C. muris, C. suis and C. viatorum in the remaining three studies (See Table 2). Recently a gp60 subtyping assay has been developed for C. viatorum [161], the only species that to date has been found exclusively in humans.

Asian Pacific Journal of Tropical Biomedicine Volume 7, Issue 5, May 2017 First molecular identification of Cryptosporidium by 18S rRNA in goats and association with farm management in Terengganu

Methods A total of 478 fecal samples were randomly collected from goats in three farms; 199 samples were collected from intensive farm, 179 samples from semi-intensive farm and 100 samples from extensive farm. Results Out of 478 goats, 207 (43.3%) were found to be infected with Cryptosporidium. Conclusions. PLOS 27/03/17 Identification and discrimination of Toxoplasma gondii, Sarcocystis spp., Neospora spp., and Cryptosporidium spp. by righ-resolution melting analysis. Abstract The objective of this study was to standardize the high-resolution melting method for identification and discrimination of Toxoplasma gondii, Sarcocystis spp., Neospora spp., and Cryptosporidium spp. by amplification of 18S ribosomal DNA (rDNA) using a single primer pair.

PLOS 27/03/17 Identification and discrimination of Toxoplasma gondii, Sarcocystis spp., Neospora spp., and Cryptosporidium spp. by righ-resolution melting analysis

The analyses were performed on individual reactions (containing DNA from a single species of a protozoan), on duplex reactions (containing DNA from two species of protozoa in each reaction), and on a multiplex reaction (containing DNA of four parasites in a single reaction). The proposed method allowed us to identify and discriminate the four species by analyzing the derivative, normalized, and difference melting curves, with high reproducibility among and within the experiments, as demonstrated by low coefficients of variation (less than 2.2% and 2.0%, respectively). This is the first study where this method is used for discrimination of these four species of protozoa in a single reaction.

Parasite Epidemiology and Control Volume 1, Issue 2, (June 2016) Prevalence and risk factors for shedding of Cryptosporidium spp. oocysts in dairy calves of Buenos Aires Province, Argentina. Abstract In order to determine the prevalence and risk factors for shedding of Cryptosporidium spp. in dairy calves, a cross-sectional study was carried out in the northeastern region of Buenos Aires Province, Argentina.

Parasite Epidemiology and Control Volume 1, Issue 2, (June 2016) Prevalence and risk factors for shedding of Cryptosporidium spp. oocysts in dairy calves of Buenos Aires Province, Argentina

Fecal samples from a total of 552 calves from 27 dairy herds were collected, along with a questionnaire about management factors. Cryptosporidium spp. oocysts were detected by light microscopy using Kinyoun staining. Putative risk factors were tested for association using generalized linear mixed models (GLMMs). Oocyst shedding calves were found in 67% (CI95% = 49–84) of herds (corresponding to a true herd prevalence of 98%) and 16% (CI95% = 13–19) of calves (corresponding to a true calve prevalence of 8%).

ETContact: Media Relations (404) 639-3286 The Cryptosporidium parasite can spread when people swallow something that has come into contact with the feces (poop) of a sick person, such as pool water contaminated with diarrhea. Outbreaks of a parasitic infection linked to swimming pools and water playgrounds are increasingly being reported to CDC, with twice as many outbreaks in 2016 as in 2014. At least 32 outbreaks caused by Cryptosporidium (also known as “Crypto”) linked to swimming pools or water playgrounds in the United States were reported in 2016, compared with 16 outbreaks in 2014, according to preliminary data published today in CDC’s Morbidity and Mortality Weekly Report.

The role of urbanization in the transmission of Cryptosporidium from wildlife. The public health significance and implications for water authorities. Abstract Cryptosporidium is an enteric parasite that is transmitted via the faecal–oral route, water and food. Keywords Cryptosporidium; Zoonotic; Wildlife; Epidemiology 1. More than 15% of the world's population has no access to safe drinking water (Cauchie et al., 2014).

In less developed countries, lack of basic infrastructure for providing safe drinking water is considered a major cause of poor water quality which contributes to the spread of endemic/epidemic waterborne diseases. Waterborne parasitic protozoans are responsible for the majority of waterborne outbreaks worldwide, with socio-economic impacts even in developed countries (Cotruva et al., 2004, Pond, 2005, Baldursson and Karanis, 2011 and Cauchie et al., 2014).

Li, Y. Guo, L. Wang, Y. Suggested citation for this article Abstract Cryptosporidium ubiquitum is an emerging zoonotic pathogen. Cryptosporidium infection is a leading cause of diarrhea in humans (1). C. ubiquitum is of public health concern because of its wide geographic distribution and broad host range. Thus far, showing an association between human and animal cases of C. ubiquitum infection has not been possible because of the lack of suitable genetic markers for subtyping.
