MICROORGANISMS 17/06/20 Prevalence and Genotypes of Cryptosporidium in Wildlife Populations Co-Located in a Protected Watershed in the Pacific Northwest, 2013 to 2016. Between October 2013 and May 2016, 506 scat samples were collected from 22 species of wildlife located in a protected watershed of a major municipal water supply in the Pacific Northwest, USA.
Overall prevalence of Cryptosporidium in the wildlife scat was 13.8% (70/506), with 15 species of wildlife found positive for Cryptosporidium. Prevalence of Cryptosporidium varied among species of wildlife, with higher prevalences observed in cougars (50.0%), mountain beavers (40.0%), and bobcats (33.3%), but none of these species are riparian-dependent.
Genotyping of Cryptosporidium by sequencing PCR amplicons from the 18S rRNA gene were successful for seven species of wildlife, including bobcat, unknown predator, black-tailed deer, deer mouse, snowshoe hare, mountain beaver, and western spotted skunk. ►▼ Show Figures Figure 1 ►▼ Show Figures. EUROPEAN JOURNAL OF MICROBIOLOGY AND IMMUNOLOGY - DEC 2019 - Cryptosporidium infection: epidemiology, pathogenesis, and differential diagnosis. Environ Sci Proc , 11/08/20 Cryptosporidium Species in Fish: An Update. Cryptosporidium species have been detected in fish, in a wide range of geographical regions.
Currently, three species are genetically characterized as piscine-host-specific: C. molnari, C. scophthalmi, C. huwi. One potential novel species, 23 additional piscine genotypes, other non-piscine-host-specific Cryptosporidium species (C. parvum, C. hominis, C. scrofarum, C. xiaoi) and the rat genotype III have been genetically characterized in fish. The pathology of cryptosporidiosis is very important for the aquaculture industry, causing mortalities in farmed fish, while the presence of Cryptosporidium zoonotic subtypes in edible fish increases the fish-borne zoonotic potential risk, which is of major importance from a public health point of view.

Résumé traduit : Le cryptosporidium a depuis été reconnu comme l'agent pathogène le plus fréquemment identifié dans les épidémies d'origine hydrique aux États-Unis . Cependant, parce que des personnes en bonne santé par ailleurs se rétablissent spontanément, il continue d'être considéré aux États-Unis principalement comme un pathogène opportuniste provoquant une diarrhée chronique chez les patients atteints du SIDA et d'autres personnes immunodéprimées. En 2013, la publication des premiers résultats de la Global Enteric Multicenter Study (GEMS) a mis en évidence l'impact de ce parasite chez les enfants des milieux à faibles ressources (LRS), dont sept pays africains et asiatiques. Le cryptosporidium s'est révélé être l'un des trois principaux agents pathogènes responsables de la diarrhée chez les enfants de moins de 12 mois et la cause la plus fréquente de mortalité due à une diarrhée modérée à sévère chez les 12 à 23 mois [4,5]. Malgré ce fardeau important et bien documenté, l'impact de la cryptosporidiose est encore sous-reconnu par la communauté mondiale de la santé au sens large: la cryptosporidiose n'est pas désignée comme une maladie tropicale négligée (MTN) par l'Organisation mondiale de la santé et ne figure pas sur la liste des maladies tropicales éligibles à un bon d'examen prioritaire (PRV) de la Food and Drug Administration (FDA) des États-Unis. Nous soulignons ci-dessous les raisons pour lesquelles la cryptosporidiose mérite fortement d'être inscrite sur la liste des maladies tropicales de la FDA et comment cela pourrait aider à stimuler le développement de thérapies améliorées. La boîte à outils actuelle des interventions contre la cryptosporidiose est sévèrement limitée. Il n'existe aucun vaccin approuvé et il n'existe qu'un seul médicament anticryptosporidien, le nitazoxanide. Bien que le nitazoxanide réduise la durée de la maladie chez les adultes immunocompétents, il est inadéquat pour les populations qui en ont le plus besoin. – guatemalt

In Brazil, approximately one-third of these species occur in freshwater ecosystems, which comprise the country’s main watersheds1. Epidemiological studies have demonstrated that the oocysts, which are the infective form of the protozoa belonging to the genus Cryptosporidium and are eliminated into the environment from the feces of infected hosts, can remain infective for several months, depending on the environmental conditions2.

These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of intestinal parasites in the pre‐ and post‐transplant period.
Intestinal parasites are prevalent in the developing regions of the world. With increasing travel to and from endemic regions, changing immigration patterns, and the expansion of transplant medicine in developing countries, they are increasingly recognized as a source of morbidity and mortality in solid‐organ transplant recipients. Parasitic infections may be acquired from the donor allograft, from reactivation, or from de novo acquisition post‐transplantation. Article_id_096_12_1562_1562_0. WIKIPEDIA (anglophone) – Cryptosporidium. Cryptosporidium is a genus of apicomplexan protozoans that can cause gastrointestinal illness with diarrhea in humans.
Cryptosporidium is the organism most commonly isolated in HIV-positive patients presenting with diarrhea. Treatment is symptomatic, with fluid rehydration, electrolyte correction and management of any pain. Cryptosporidium oocysts are 4-6 µm in diameter and exhibit partial acid-fast staining. They must be differentiated from other partially acid-fast organisms including Cyclospora cayetanensis.

Introduction The IUCN status of Mountain gorillas has changed from critically endangered to endangered with a recent population estimate of 1,004 (1), found in two distinct populations: Bwindi Impenetrable Forest in Uganda, and the Virunga Volcanoes in Rwanda, Democratic Republic of Congo (DRC) and Uganda. Human poverty and high human population growth rates affect environmental sustainability, including survival of gorillas, through habitat destruction due to a greater need for firewood and food from the gorillas' habitat (2, 3) and through increased infectious disease incidences in poorer households that come into direct contact with gorillas ranging in their gardens.
At Bwindi Impenetrable National Park and in other remote locations in Uganda bordering protected areas, family sizes often range from 8 to 10, and as such are less able to provide basic modern healthcare to all their children. There have been studies of intestinal helminth parasites in Bwindi gorillas (7, 8). Methods. BMC Veterinary Research 28/03/19 Molecular identification and epidemiological comparison of Cryptosporidium spp. among different pig breeds in Tibet and Henan, China. Among the 23 Cryptosporidium-positive samples identified by PCR, only 5 were detected by microscopy, which may be caused by the low concentration of Cryptosporidium oocyst in fecal specimens. In this study, the Cryptosporidium prevalence in Henan was 4.21%, which is lower than that in many reported areas of China, such as Guangdong (8.33%, 6/72), Zhejiang (14.52%, 18/124), Yunnan (23.00%, 46/200), Shanghai (34.44%, 800/2323), Heilongjiang (55.75%, 63/113), and other regions, but only higher than Shaanxi (3.29%, 44/1337) (Table 2) [21–27].
Surprisingly, the infection rate of Cryptosporidium in Tibet is lower than in any reported areas (Table 2). The present study also indicated that the Cryptosporidium infection rates in both local pig breeds were lower than that in imported pig breed. PLOS 13/07/17 Local and global genetic diversity of protozoan parasites: Spatial distribution of Cryptosporidium and Giardia genotypes. Abstract 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 gain insights into the geographical distribution and spatial patterns of Cryptosporidium and Giardia parasites. Here, we describe the population heterogeneity of genotypic groups within Cryptosporidium and Giardia present in New Zealand using gp60 and gdh markers to compare the observed variation with other countries around the globe.
