A family of parasitic organisms in the order EIMERIIDA. CRYPTOSPORIDIUM is the most important genus.
A subclass of protozoans commonly parasitic in the epithelial cells of the intestinal tract but also found in the liver and other organs. Its organisms are found in both vertebrates and higher invertebrates and comprise two orders: EIMERIIDA and EUCOCCIDIIDA.
A genus of coccidian parasites of the family CRYPTOSPORIDIIDAE, found in the intestinal epithelium of many vertebrates including humans.
Common name for the order Pleuronectiformes. A very distinctive group in that during development they become asymmetrical, i.e., one eye migrates to lie adjacent to the other. They swim on the eyeless side. FLOUNDER, sole, and turbot, along with several others, are included in this order.
Intestinal infection with organisms of the genus CRYPTOSPORIDIUM. It occurs in both animals and humans. Symptoms include severe DIARRHEA.
Zygote-containing cysts of sporozoan protozoa. Further development in an oocyst produces small individual infective organisms called SPOROZOITES. Then, depending on the genus, the entire oocyst is called a sporocyst or the oocyst contains multiple sporocysts encapsulating the sporozoites.
A species of parasitic protozoa that infects humans and most domestic mammals. Its oocysts measure five microns in diameter. These organisms exhibit alternating cycles of sexual and asexual reproduction.
Infections with protozoa of the phylum CILIOPHORA.
A genus of protozoan parasites of the subclass COCCIDIA. Various species are parasitic in the epithelial cells of the liver and intestines of man and other animals.
A genus of flagellate intestinal EUKARYOTES parasitic in various vertebrates, including humans. Characteristics include the presence of four pairs of flagella arising from a complicated system of axonemes and cysts that are ellipsoidal to ovoidal in shape.
An infection of the SMALL INTESTINE caused by the flagellated protozoan GIARDIA LAMBLIA. It is spread via contaminated food and water and by direct person-to-person contact.
A species of parasitic EUKARYOTES that attaches itself to the intestinal mucosa and feeds on mucous secretions. The organism is roughly pear-shaped and motility is somewhat erratic, with a slow oscillation about the long axis.
Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks.

Kinetic characterization of bifunctional thymidylate synthase-dihydrofolate reductase (TS-DHFR) from Cryptosporidium hominis: a paradigm shift for ts activity and channeling behavior. (1/3)

This study presents a kinetic characterization of the recently crystallized bifunctional thymidylate synthasedihydrofolate reductase (TS-DHFR) enzyme from the apicomplexa parasite, Cryptosporidium hominis. Our study focuses on determination of the C. hominis TS-DHFR kinetic mechanism, substrate channeling behavior, and domain-domain communication. Unexpectedly, the unique mechanistic features of C. hominis TS-DHFR involve the highly conserved TS domain. At 45 s(-) (1), C. hominis TS activity is 10-40-fold faster than other TS enzymes studied and a new kinetic mechanism was required to simulate C. hominis TS behavior. A large accumulation of dihydrofolate produced at TS and a lag in product formation at DHFR were observed. These observations make C. hominis TS-DHFR the first bifunctional TS-DHFR enzyme studied for which there is clear evidence against dihydrofolate substrate channeling. Furthermore, whereas with Leishmania major TS-DHFR there are multiple lines of evidence for domain-domain communication (ligand binding at one active site affecting activity of the other enzyme), no such effects were observed with C. hominis TS-DHFR.  (+info)

Issue a boil-water advisory or wait for definitive information? A decision analysis. (2/3)

OBJECTIVE: Study the decision to issue a boil-water advisory in response to a spike in sales of diarrhea remedies or wait 72 hours for the results of definitive testing of water and people. METHODS: Decision analysis. RESULTS: In the base-case analysis, the optimal decision is test-and-wait. If the cost of issuing a boil-water advisory is less than 13.92 cents per person per day, the optimal decision is to issue the boil-water advisory immediately. CONCLUSIONS: Decisions based on surveillance data that are suggestive but not conclusive about the existence of a disease outbreak can be modeled.  (+info)

Roxburgh and Lake Roxburgh Village were put on boil-water notices on Wednesday, while Alexandra was added to the list on Thursday, following high water levels on the Clutha River.. Increased levels meant water supplies were at risk of containing harmful micro-organisms.. People in affected areas should bring tap water to a full rolling boil for one minute and then let it cool before using it.. A Central Otago District Council spokeswoman has also encouraged people to conserve water until the situation improved.. Roxburgh and Lake Roxburgh Village were put on boil-water notices at 5.30pm on Wednesday, while Alexandra was added to the list at 11am yesterday.. The announcements were made after tests showed the water supply to those towns potentially contained harmful micro-organisms, following high water levels on the Clutha River.. As a result, levels of silt were elevated, a council spokeswoman said.. More rain is forecast, so we need to be cautious.. Water from the river is entering the ...
LAKE JACKSON, Texas (AP) - A boil-water notice was lifted Tuesday from the drinking-water system of a Houston-area city where water tainted with a deadly, microscopic parasite was blamed for the death of a 6-year-old boy. In a statement, the Texas Commission on Environmental Quality said Lake Jackson officials lifted the notice Tuesday after disinfectant […]
The Labrador community of Nain issued a boil-water advisory Friday morning after two teenagers found a dead dog in the water supply.

On Earth Magazine. When Josie Nieto visits her relatives in Mexicali, Mexico, she luxuriates in long showers. And when shes thirsty, she enjoys a glass of water straight from the kitchen tap. At Nietos own house, the water pressure is so low it can take her 45 minutes to shower and shampoo. And sometimes theres no water at all, which is why some of her neighbors hoard water in buckets. Its fine for laundry and houseplants, but Nieto isnt keen on drinking the stuff. The main pipe of her community water system runs straight down the middle of an irrigation ditch. Ive seen dead animals in there, Nieto says.. The plastic water pipe itself suffers frequent breaks, which can allow contaminants to seep into the system. Washer screens on fixtures routinely trap sand and flecks of rust; a neighbor without a screen once drew from his tap a tall glass of polliwogs. In response to bacterial spikes, the water-system operator sends out boil-water notices, but boiling when nitrate levels rise would ...
Several areas affected by the wildfires are experiencing electrical outages that may cause water systems to lose pressure and may allow harmful contaminants into water lines, said the Washington State Department of Health. Residents who have lost water pressure should boil their tap water when service is restored. Guidance for customers of affected water systems can be found online.. In order to kill germs, water should be heated to a brisk boil for one minute and allowed to cool before use, the department advises. The boil-water advisory remains in effect until tests show the water is safe to drink. People who are unsure about whether their water is safe to drink should contact their water system.. The department said its also important that people in wildfire areas pay attention to current air quality information, which can be found on the Washington State Department of Ecologys website. Breathing smoke from wildfires can make anyone cough or wheeze, and people who have asthma or another ...
Cryptosporidium spp. are protozoan parasites of the phylum Apicomplexa, class Sporozoasida, subclass Coccidia, order Eucoccidiorida, family Cryptosporidiidae
The translocase of the outer membrane (TOM complex) forms the entry gate for the majority of mitochondrial precursor proteins. Subsequently, specific protein complexes sort the precurcor proteins into the different subcompartments. The presequence translocase (TIM23 complex) transport proteins across and into the inner membrane. The TIM23 complex cooperates with the presequence-translocase associated motor (PAM) for transport into the mitochondrial matrix. The carrier translocase (TIM22 complex) inserts proteins into the inner membrane. The activity of the respiratory chain generates a membrane potential that drives both protein import pathways. The MIA machinery transports cysteine-rich proteins into the intermembrane space. Outer membrane proteins with β-barrel structure are first transported across the TOM machinery and then inserted into the outer membrane by the sorting and assembly machinery (SAM complex). Finally, the mitochondrial import machinery (MIM) promotes biogenesis of outer ...
SWISS-MODEL Template Library (SMTL) entry for 3dl6. Crystal Structure of the A287F/S290G Active Site Mutant of TS-DHFR from Cryptosporidium hominis
Cryptosporidium hominis and Cryptosporidium parvum belong to the family of Cryptosporidiidae, unicellular parasites that cause the clinically manifested diarrhoea disease cryptosporidiosis. Species such as C. canis or C. felis seldomly infect humans. In particular, livestock such as cattle, horses and goats as well as domestic animals including dogs, cats and birds are regarded as sources and hosts of zoonotic cryptosporidia. Infections with C. hominis originate exclusively from humans themselves. First recorded as a human pathogen in 1976, cryptosporidia can currently be detected in the faeces in two to four percent of diarrhoeal patients in industrialised countries. The pathogen forms four to six micrometre (μm) large oocysts - a microscopically visible stage in the life cycle of parasitic protozoa - which are then excreted by the host. The sporozoites - the infectious developmental stage of the parasites - are then responsible for an infection. ...
