First isolation of Sarcocystis hominis from cattle in Japan. (1/64)

Sarcocystis hominis was first isolated from slaughtered cattle raised in Japan. Cysts were 1,220-4,460 x 80-384 microns in size and their wall was 3 to 6 microns thick and appeared radially striated in the histopathological sections because of the presence of palisade-like villar protrusions on the surface. The protrusions were 3.1-4.3 x 0.7-1.1 microns in size and had many microtubules in the core. Two cynomolgus monkeys, Macaca fascicularis, fed with the Sarcocystis cysts began to pass sporocysts, which measured a size of 14.3-15 x 9.5-10 microns, in the feces 10 days after ingestion.  (+info)

An outbreak of acute eosinophilic myositis attributed to human Sarcocystis parasitism. (2/64)

Seven members of a 15-man U.S. military team that had operated in rural Malaysia developed an acute illness consisting of fever, myalgias, bronchospasm, fleeting pruritic rashes, transient lymphadenopathy, and subcutaneous nodules associated with eosinophilia, elevated erythrocyte sedimentation rate, and elevated levels of muscle creatinine kinase. Sarcocysts of an unidentified Sarcocystis species were found in skeletal muscle biopsies of the index case. Albendazole ameliorated symptoms in the index case; however, his symptoms persisted for more than 5 years. Symptoms in 5 other men were mild to moderate and self-limited, and 1 team member with laboratory abnormalities was asymptomatic. Of 8 team members tested for antibody to Sarcocystis, 6 were positive; of 4 with the eosinophilic myositis syndrome who were tested, all were positive. We attribute this outbreak of eosinophilic myositis to accidental tissue parasitism by Sarcocystis.  (+info)

Improvement of western blot test specificity for detecting equine serum antibodies to Sarcocystis neurona. (3/64)

Equine protozoal myeloencephalitis (EPM) is a neurological disease of horses and ponies caused by the apicomplexan protozoan parasite Sarcocystis neurona. The purposes of this study were to develop the most stringent criteria possible for a positive test result, to estimate the sensitivity and specificity of the EPM Western blot antibody test, and to assess the ability of bovine antibodies to Sarcocystis cruzi to act as a blocking agent to minimize false-positive results in the western blot test for S. neurona. Sarcocystis neurona merozoites harvested from equine dermal cell culture were heat denatured, and the proteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis in a 12-20% linear gradient gel. Separated proteins were electrophoretically transferred to polyvinylidene fluoride membranes and blocked in 1% bovine serum albumin and 0.5% Tween-Tris-buffered saline. Serum samples from 6 horses with S. neurona infections (confirmed by culture from neural tissue) and 57 horses without infections (horses from the Eastern Hemisphere, where S. neurona does not exist) were tested by Western blot. Horses from both groups had reactivity to the 62-, 30-, 16-, 13-, 11-, 10.5-, and 10-kD bands. Testing was repeated with another step. Blots were treated with bovine S. cruzi antibodies prior to loading the equine samples. After this modification of the Western blot test, positive infection status was significantly associated with reactivity to the 30- and 16-kD bands (P<0.001, Fisher's exact test). The S. cruzi antibody-blocked Western blot had a sample sensitivity of 100% and sample specificity of 98%. It is concluded that the specificity of the Western blot test is improved by blocking proteins not specific to S. neurona and using reactivity to the 30- and 16-kD bands as the criterion for a positive test.  (+info)

Sarcocystis sp. from cattle slaughtered in Japan. (4/64)

Sarcocystis sp. was detected from cattle slaughtered in Saitama Prefecture, Japan. The cysts were 3,400-4,400 x 198-238 microm in size and had the thick cyst wall which was 7 to 10 microm thick and provided with finger-like villar protrusions. The protrusions were 8-9.5 x 2-2.5 microm in size and had microtubules in the core.  (+info)

Binding of a monoclonal antibody to sporozoites of Sarcocystis singaporensis enhances escape from the parasitophorous vacuole, which is necessary for intracellular development. (5/64)

Early intracellular development in vitro of the cyst-forming protozoon Sarcocystis singaporensis and the influence of a monoclonal antibody on invasion, intracellular localization, and development of sporozoites were studied. As revealed by immunofluorescence using parasite-specific antibodies which labeled the parasitophorous vacuole membrane (PVM) and by ultrastructural analysis, sporozoites invaded pneumonocytes of the rat via formation of a parasitophorous vacuole (PV). About half of the sporozoites left this compartment within the first 8 h postinfection to enter the host cell cytosol. By semiquantitative analysis of acetyl-histone H4 expression of sporozoites, a marker linked to early gene expression of eukaryotic cells, we show (supported by ultrastructural analysis) that escape from the PV appears to be necessary for early intracellular development. More than 90% of sporozoites located in the cytosol expressed high levels of acetylated histone H4 in the nucleus, whereas only a quarter of the intravacuolar sporozoites exhibited a similar signal. As revealed by ultrastructural analysis, young schizonts all resided in the cytosol. Specific binding of a monoclonal antibody (11D5/H3) to sporozoites before invasion significantly enhanced their escape from the PV, whereas cell invasion itself remained unaffected. The antibody actually increased proliferation of the parasites in vitro, providing a further link between residence in the cytosol and successful intracellular development. Monoclonal antibody 11D5/H3 precipitated a major 58-kDa antigen from oocyst-sporocyst extracts and reacted with the cytoplasm and the surface of sporozoites in immunofluorescence assays. Collectively, the observed antibody-parasite interaction suggests the existence of a signaling event that influences intracellular development of Sarcocystis.  (+info)

Experimental induction of the two-host life cycle of Sarcocystis cruzi between dogs and Korean native calves. (6/64)

Eight dogs were experimentally infected with Sarcocystis by oral inoculation of cardiac muscle from naturally infected cattle. The infected dogs commenced discharging of sporocysts in the feces after 10 to 12 days of inoculation, and continued until 20 and 35 days after inoculation. Three dogs were reinfected with cardiac muscle from the naturally infected cattle. Sporocysts reappeared in the feces on 12 to 13 days after reinfection. Sarcocystis sporocysts collected from the experimentally infected dogs were fed to each of the two 30-day-old Korean native calves. The infected calves remained clinically normal, except for the high fever (> or = 40 degrees C) and decreased hematocrit values on day 30 to 40 post inoculation. Muscular cysts of Sarcocystis were found from infected calves on day 40 post inoculation. Proliferative forms of Sarcocystis were also observed in the muscle of infected calves. These results suggest that the Sarcocystis cruzi found in Korean native cattle has a 2-host life cycle with dogs as the definitive host and Korean native calves as the intermediate host.  (+info)

Reduced levels of nitric oxide metabolites in cerebrospinal fluid are associated with equine protozoal myeloencephalitis. (7/64)

Equine protozoal myeloencephalitis (EPM) is a disease of horses that is primarily associated with infection with the apicomplexan Sarcocystis neurona. Infection with this parasite alone is not sufficient to induce the disease, and the mechanism of neuropathogenesis associated with EPM has not been reported. Nitric oxide (NO) functions as a neurotransmitter, a vasodilator, and an immune effector and is produced in response to several parasitic protozoa. The purpose of this work was to determine if the concentration of NO metabolites (NO(x)(-)) in the cerebrospinal fluid (CSF) is correlated with the development of EPM. CSF NO(x)(-) levels were measured before and after transport-stressed, acclimated, or dexamethasone-treated horses (n = 3 per group) were experimentally infected with S. neurona sporocysts. CSF NO(x)(-) levels were also compared between horses that were diagnosed with EPM after natural infection with S. neurona and horses that did not have clinical signs of disease or that showed no evidence of infection with the parasite (n = 105). Among the experimentally infected animals, the mean CSF NO(x)(-) levels of the transport-stressed group, which had the most severe clinical signs, was reduced after infection, while these values were found to increase after infection in the remaining groups that had less severe signs of EPM. Under natural conditions, horses with EPM (n = 65) had a lower mean CSF NO(x)(-) concentration than clinically normal horses with antibodies (Abs) against S. neurona (n = 15) in CSF, and horses that developed ataxia (n = 81) had a significantly lower mean CSF NO(x)(-) concentration than horses that did not have neurologic signs (n = 24). In conclusion, lower CSF NO(x)(-) levels were associated with clinical EPM, suggesting that measurement of CSF NO(x)(-) levels could improve the accuracy of diagnostic tests that are based upon detection of S. neurona-specific Abs in CSF alone and that reduced NO levels could be causally related to the development of EPM.  (+info)

Pathology of sarcocystis neurona in interferon-gamma gene knockout mice. (8/64)

Pathologic changes were studied in 27 interferon-gamma gene knockout mice 34-54 days after being fed graded doses of Sarcocystis neurona sporocysts derived from a naturally infected opossum. The target tissue for S. neurona infection was the central nervous system. Characteristic histopathologic changes present in all mice consisted of an inflammatory infiltrate consisting of mostly neutrophils and macrophages, fewer eosinophils, and rare multinucleated giant cells. Intralesional protozoa and scattered subacute perivascular cuffs were present. Where the infiltrates were extensive, neuropil rarefaction was frequent. Pathologic changes were much more frequent and severe in the caudal portion of the brain, especially in the cerebellum, than in the middle and cranial portions. Changes were present in all spinal cords examined (10 of 10). Lesions were equally distributed in white and gray matter of the brain and spinal cord and their meningeal linings.  (+info)

Sarcocystis are intracellular protozoan parasites that are characterised by their ability to invade muscle tissue and form intramuscular sarcocysts. A muscular sarcocystosis outbreak was reported by travellers returning from Tioman Island in 2011 and 2012 where Sarcocystis nesbitti was identified as the main cause. The source of the S. nesbitti that was involved has remained elusive, although water is hypothesised to be the main cause of transmission. A surveillance study was therefore undertaken in the northern regions of Tioman Island to identify the source of S. nesbitti by screening rivers, water tanks, wells and seawater. Water samples were collected from rivers, water tanks, wells and seawater on Tioman Island over the course of April to October 2015. Water samples were indirectly screened for Sarcocystis species by obtaining sediment from respective water sources. PCR amplification of the 18S rRNA gene region was conducted to identify positive samples. Microscopy was

Sarcocystis neurona is the most common cause of Equine Protozoal Myeloencephalitis (EPM), affecting 0.5-1% horses in the United States during their lifetimes. The objective of this study was to evaluate the equine immune responses in an experimentally induced Sarcocystis neurona infection model. Neurologic parameters were recorded prior to and throughout the 70-day study by blinded investigators. Recombinant SnSAG1 ELISA for serum and CSF were used to confirm and track disease progression. All experimentally infected horses displayed neurologic signs after infection. Neutrophils, monocytes, and lymphocytes from infected horses displayed significantly delayed apoptosis at some time points. Cell proliferation was significantly increased in S. neurona-infected horses when stimulated nonspecifically with PMA/I but significantly decreased when stimulated with S. neurona compared to controls. Collectively, our results suggest that horses experimentally infected with S. neurona manifest impaired ...
Sarcocystosis is caused by species of Sarcocystis, an intracellular protozoan parasite in the phylum Apicomplexa. These parasites have an indirect life cycle, cycling between a definitive and an intermediate host. Intestinal infections occur in the definitive host, and tissue invasion is seen in the intermediate host. More than a hundred species of Sarcocystis are parasites of domestic and wild animals. Many of these infections are asymptomatic, particularly in the definitive host. Equine protozoal myeloencephalitis is usually caused by Sarcocystis neurona. Neospora caninum and/or Neospora hughesi, not discussed in this outline, have also been implicated in some cases. Symptomatic infections caused by Sarcocystis species are reported occasionally in other domestic animals. Humans are a definitive host for S. suihominis, found in pork, and S. hominis, found in beef. These parasites infect the intestines. Humans can be intermediate hosts for a variety of other Sarcocystis species. The parasites are found
The aim of the study was to diagnose Sarcocystis sp. infections in cattle and to detect coinfections by Toxoplasma gondii and/or Neospora caninum. Blood, diaphragm, esophagus, and myocardium from 90 beef cattle from Argentina were collected. Histopathological, immunohistochemical, polymerase chain reaction assays, and direct microscopical examination were carried out. Sarcocysts from myocardium were measured and counted. Indirect fluorescent antibody test (IFAT) for the three protozoans was performed. Sarcocystis cruzi sarcocysts were found in 100% of myocardium samples. Sarcocysts per gram ranged from 8 to 380 with higher values found in adult cattle (p < 0.001). T. gondii and N. caninum were not detected by immunohistochemistry. T. gondii DNA was found in myocardium of 2/20 seropositive animals, while N. caninum DNA was not found. Antibodies against S. cruzi were detected in all samples, those against N. caninum in 73% and against T. gondii in 91% of the samples (IFAT titer >/=25). It is ...
The present study examined the seroprevalence of Toxoplasma gondii and Sarcocystis neurona in a population of beavers (Castor canadensis) from Massachusetts. Sixty-two blood samples were collected during the field seasons over 3 consecutive years from different animals. Blood was collected onto filter paper and shipped to the Department of Biomedical Sciences, Virginia Tech, Blacksburg, Virginia, for parasite testing. The samples were tested at dilutions of 1:25. 1:50, and]:100 against each parasite antigen by modified agglutination tests to determine whether antibodies to either parasite were present in the blood. Six of 62 samples (10%) were positive for T. gondii, with 2 samples having titers of 1:25 and 4 having titers of 1:50. Four of 62 samples (6%) were positive for S. neurona, with 2 samples having titers of 1:25 and 2 having titers of 1:50 ...

An adult female sea otter housed for 5 years in an outdoor habitat in an aquarium developed signs of neurologic disease. Bilateral caudal paresis was evident initially and other neurologic signs consistent with CNS disease developed rapidly. Diagnostic work-up included CBC, serum biochemical analyses, determination of serum antibody titers, radiography of the vertebral column, CSF analysis, muscle biopsy, computed tomography of the brain, and assays for mercury, lead, and thiamine. A tentative diagnosis of encephalitis caused by a Sarcocystis neurona-like organism was made on the basis of detection of CSF antibodies by use of Western blot analysis. Response to treatment was not satisfactory and the sea otter was euthanatized. Immunohistochemical staining revealed S neurona-like organisms within foci of inflammation in the brain and spinal cord. This report provides evidence that, for sea otters, there may be a mode of transmission of an S neurona-like organism that does not involve ...
The effect of temperature and relative humidity (RH) on the survival of sporocysts of S. cruzi were investigated in vitro. Under all experimental conditions (temperature of 4°C, 37°C or room temperature; RH of 18%, 75%, or 100%) some sporozoites retained their viability to excyst for at least 90 days. The best conditions for survival were 4°C at 100% RH (more than 240 days) and 37°C at 18% RH (more than 180 days). Sporocysts maintained at room temperature at all humidities had the lowest level of survival. It is concluded that sporocysts of S. cruzi are able to survive in most environments for several months and that the fluctuation of the daily ambient temperature is likely to influence the viability of the sporocysts.. ...

The widespread protozoan parasite Toxoplasma gondii interferes with host cell functions by exporting the contents of a unique apical organelle, the rhoptry. Among the mix of secreted proteins are an expanded, lineage-specific family of protein kinases termed rhoptry kinases (ROPKs), several of which have been shown to be key virulence factors, including the pseudokinase ROP5. The extent and details of the diversification of this protein family are poorly understood. In this study, we comprehensively catalogued the ROPK family in the genomes of Toxoplasma gondii, Neospora caninum and Eimeria tenella, as well as portions of the unfinished genome of Sarcocystis neurona, and classified the identified genes into 42 distinct subfamilies. We systematically compared the rhoptry kinase protein sequences and structures to each other and to the broader superfamily of eukaryotic protein kinases to study the patterns of diversification and neofunctionalization in the ROPK family and its subfamilies. We identified

DIAGNOSIS: TOXOPLASMOSIS. DISCUSSION:. The immunohistochemical study was positive for Toxoplasma gondii demonstrating positive staining for the bradyzoites within the cysts and pseudo-cysts as well as individual tachyzoites in the necrotic tissue. Histopathological diagnosis of toxoplasmosis could be difficult due to the fact that cysts are difficult to recognize. These cysts may resemble those seen in other infections such as Leishmania donovani, Trypanosoma cruzi, Sarcocystis, Besnoitia and so on (1) Immunohistochemical stains now reveal the true nature of the microorganism, although electron microscopy can be used. Toxoplasmosis is a common CNS infection in AIDS patients (2,3). The characteristic lesion is a necrotizing acute abscess (1). Toxoplasmosis is well known as an intrauterine infection with devastating consequences but it is far more rare in settings outside of these. Although reported in post-transplanted patients, there have been virtually no reports of CNS toxoplasmosis in ...
Beyond the evidence presented at the trial, PETA has never backed up its claim with any evidence to suggest that it only takes in injured or otherwise unadoptable dogs and cats. That said, it was very hard for me to listen to my cats begging for food even though I was strong in my conviction that I was heading them in the best direction for optimal health.

Summary The pathogenesis of toxoplasmosis is discussed under the headings of Host, Microorganism, Treatment and Time, in an attempt to integrate the many factors operating during infection. The obligate intracellular development of Toxoplasma, its ability to grow in many cells and the formation of a relatively inert cyst are the major microorganismal attributes determining pathogenesis. Whereas many natural hosts appear relatively resistant to many of the strains, the inability of some hosts to overcome infection or to develop an effective immunity and, furthermore, the presence of an infection-immunity (premunition), the development of hypersensitivity with chronic infection and the results of cyst rupture are the major host factors complicating pathogenesis. Our knowledge of the shifting relative importance of each factor while infection progresses is inadequate. The analysis of the pathogenesis must take into account the effects of superimposition of different rates of a variety of processes. It has

Nikotinski acetilholinski receptori (nAChR) su holinergički receptori koji formiraju ligandom kontrolisane jonske kanale u ćelijskim membranama pojedinih neurona i na postsinaptičkoj strani neuromaskularnog spoja. Kao jonotropni receptori, nAChR su direktno vezani za jonske kanale i ne koriste sekundarne glasnike (poput metabotropnih receptora). Nikotinski acetilholinski receptori su najbolje ispitani među jonotropnim receptorima.[1] Poput drugih tipova acetilholinskih receptora (npr. muskarinskih acetilholinskih receptora - mAChR) nAChR se iniciraju vezivanjem neurotransmitera acetilholina (ACh). Dok su muskarinski receptori isto tako aktivirani muskarinom, nikotinski receptori mogu da budu aktivirani nikotinom. Iz tog razloga se nazivaju nikotinskim receptorima.[1][2][3] Postoje tri tipa nikotinskih receptora: mišićni, ganglijski i CNS.[4] ...

OBJECTIVES: To determine whether vitamin A supplements result in reduced mortality among HIV-infected and uninfected children. DESIGN: Randomized, double blind, placebo-controlled trial. METHODS: Starting in April, 1993, we randomized 687 children age 6 months to 5 years who were admitted to the hospital with pneumonia. Children who were severely malnourished or had clinical signs of vitamin A deficiency were excluded. At baseline children received placebo or 400 000 IU (or half that for infants) of vitamin A, in addition to standard treatment for pneumonia. They received further doses of the same regimen 4 and 8 months after hospital discharge. Sera from children were tested for HIV antibodies by enzyme-linked immunosorbent assay and Western blot tests. For positive children ,15 months of age, HIV infection was confirmed by amplified heat-denatured ...

Through 2 international traveler-focused surveillance networks (GeoSentinel and TropNet), we identified and investigated a large outbreak of acute muscular sarcocystosis (AMS), a rarely reported zoonosis caused by a protozoan parasite of the genus Sarcocystis, associated with travel to Tioman Island, Malaysia, during 2011-2012.; Clinicians reporting patients with suspected AMS to GeoSentinel submitted demographic, clinical, itinerary, and exposure data. We defined a probable case as travel to Tioman Island after 1 March 2011, eosinophilia (,5%), clinical or laboratory-supported myositis, and negative trichinellosis serology. Case confirmation required histologic observation of sarcocysts or isolation of Sarcocystis species DNA from muscle biopsy.; Sixty-eight patients met the case definition (62 probable and 6 confirmed). All but 2 resided in Europe; all were tourists and traveled mostly during the summer months. The most frequent symptoms reported were myalgia (100%), fatigue (91%), fever ...
Equine protozoal myeloencephaltis is a serious health concern for horse owners. Although more than half of horses infected with this disease will respond to treatment, about 40% do not and eventually die from the deterioration of their central nervous system. Sadly, only one-tenth of infected horses completely recover from the infection. Learning the equine protozoal myeloencephalitis symptoms can help you get treatment for your horse quickly.. Recognizing Symptoms. The equine protozoal myeloencephalitis symptoms can be different in the infected horses because the infection causes lesions to appear in different areas of the brain. Depending on where these lesions show up, the symptoms change. Most of the more common symptoms involve lameness, loss of coordination, changes in the horses gait, and muscle atrophy. Other symptoms can include head tilting, leaning against the stall wall for balance, paralysis of the face, and loss of feeling in the head and neck area. When your horse begins showing ...
Sarcocystosis is characterized by the invasion of muscles and sometimes other tissues by protozoa of the genus Sarcocystis, of which S. hominis (intermediate host domestic cattle) and S. suihominis (domestic pig) are the most significant to humans, to whom they are transmitted by ingestion of uncooked beef or pork. Humans serve as either intermediate or final host: (1) intermediate host-presence of cysts in muscle is usually asymptomatic, but may cause myositis or myopathy; detected on clinical examination or muscle biopsy; (2) final host-may be asymptomatic or cause fever and gastrointestinal upset; oocysts or sporocysts can be detected in faeces. There is no specific treatment. Prevention is by not eating uncooked meat from any animal....

Until the availability of molecular testing, it was almost impossible to definitively identify the causative agent and infection status of an affected horse. If a horse showed signs of neurologic problems, the veterinarian began a process of elimination to determine what was NOT causing the symptoms. Traditional EPM tests were only effective at determining that the horse did not have EPM. If traditional EPM test results were positive, that only definitively revealed that the horse had been exposed in the past to the parasites that cause EPM. Testing could not show whether the horse had an active infection by those parasites. ...

A 7-year-old lioness was found in the Nairobi National park in January 1990 paralysed from the neck down. The lioness was destroyed and PM examination revealed congested spleen and lungs, chronic interstitial nephritis and hyaline degeneration of nephrons and the intestinal mucosa covered in thick creamy matter and diffusely infiltrated by lymphocytes. Two roundworms, Toxocara canis and a mass of entangled tapeworms, Taenia gonyami were present in the small intestine. Numerous cysts of Microbesnoitia leoni measuring 22 to 32 by 43 to 88 µm were present in the cardiac and skeletal muscles. Numerous sarcocysts measuring 113 to 114 by 730 to 760 µm were present in skeletal muscles. Negri bodies were present in the cytoplasm of neurones in the caudate nucleus, hippocampus, around the third ventricle in the mesencephalon, pons and medulla oblongata. They were larger and more numerous in the Purkinje cells of the cerebellum than in the hippocampus. A mild lymphocytic meningitis was seen over the ...

Maureen Long is a PeerJ user. Bio: Our laboratory investigates primarily vector-borne pathogens that affect humans and animals. Research interests include several equine and large animal infectious diseases with emphasis currently on mosquito borne flaviviruses and alphaviruses. Other pathogens currently under investigation include the human pathogens Dengue virus and recently Zika virus. We are interested primarily in using an -omics approach to determine why certain animals/people actually develop diseases while others do not. We have studied WNV in horses and birds and performed surveillance in horses and people for several mosquito-borne viruses. We have just complete work using a transcriptomic approach to comparing viral infection of the brain (West Nile virus) to protozoal infection of the brain (Sarcocystis neurona) in the horse. We have an area of investigation in the mosquito borne disease of dogs, Dirofilaria immitis, which causes heartworm. We have a large collection of reference materials
A $1.86 million grant from the National Science Foundation - National Institutes of Health Ecology of Infectious Disease Grant Program will expand the investigations of a UC Davis-led research team tracking how a deadly parasite moves from land to sea to infect and kill sea otters (Enhydra lutris nereis) in California. Weve already identified the single-celled parasite, Toxoplasma gondii, that causes high rates of mortality in threatened southern sea otters, says Patricia Conrad, professor of parasitology at the UC Davis School of Veterinary Medicine. Conrad, the principal investigator, says, Toxoplasma infections are killing southern sea otters and are one of several factors reducing the potential for sea otter population recovery. Sea otters do not prey on known intermediate hosts for T. gondii, says Conrad, so the most likely source of infection is highly infectious, egg-like oocysts shed in the feces of cats and transported via freshwater runoff into the marine ecosystem. Toxoplasma ...

The U.S. Food and Drug Administration announced May 15 that four horses have died after receiving compounded drug products, containing pyrimethamine and toltrazuril, used to treat equine protozoal myeloencephalitis. The compounds originated at Wickliffe Pharmacy in Lexington, Ky.. Six additional horses have suffered adverse effects, including fever and seizure, from the medication but are now recovering.. One lot of the compound was a paste and one was an oral suspension. The FDA reports that all of the products in the lots are accounted for and are no longer in distribution.. [The] FDA is working with the pharmacy and state partners to investigate these adverse events, stated an FDA release. At this time, FDA testing indicates that one lot of product contained higher levels of pyrimethamine than the labeling indicates. Adverse events associated with high doses of pyrimethamine include seizures, fever and death. Two of the horses were located in Kentucky and eight in Florida.. These ...
Competing Friday in the 53rd annual Abdallah Shrine Rodeo at the Leavenworth County Fairgrounds had extra significance for Paige Boylan.. The 2011 Tonganoxie High School graduate not only competed in her hometown in the barrel-racing event of the Shrine Rodeo for the first time but also its is part of what she is calling a rebuilding year with her teammate: her quarterhorse Queenie.. A year ago, her horse was diagnosed with equine protozoal myeloencephalitis, a condition in which a parasite affects the central nervous system. Three months later, Queenie suffered a bone infection in one of her back legs and lost 200 pounds in the process.. Ive had a big support group throughout my horse being sick and people upping my confidence and my horse getting better, she said. I thought she was done after last year.. But a resilient Queenie has gained back the weight and now weighs nearly 1,100 pounds.. Looking at her today, you would have never known she was sick last year, Boylan said.. Though an ...
Southern Sea Otters (Enhydra lutris nereis) are a fixture in Monterey Bay, California. On our whale watch last year, we saw this little whiskered fellow hanging out by a kelp forest and munching on a clam. At first, he was floating on his back in the water with a clam on his chest and next he had cracked the clam and was eating. They are such delightful creatures. Although the Southern Sea Otter population is much larger than earlier in the 20th Century, they are still dying at alarming rates and struggling to survive. The Monterey Bay Aquarium is doing a lot of research on these otters and has a wonderful exhibit of otters who are unable to be released back into the wild ...

Adriano Aguzzi, a professor of neuropathology and director of the Swiss National Creutzfeldt-Jakob Disease Surveillance Center in Zurich, Switzerland, said in an e-mail that IHC can be as sensitive as the Western blot method in certain specific instances. Aguzzis institution, however, routinely runs a Western blot test enhanced with another step on every suspect case, because of its unrivalled specificity and because in most cases we find it to be much more sensitive than immunohistochemistry.. In the months since the November announcement, the USDA came under intense pressure from organizations such as Consumers Union for failing to conduct a Western blot test on the suspect cow.. Activists at Consumers Union pointed to reports in veterinary literature which suggested IHC could miss some cases.. Michael Hansen, a senior research associate with Consumers Union, says he confronted USDA officials about the issue during the June 6 meeting of Institute of Medicine of the National ...

Eritropoietin (eritropoetin, hemopoietin, EPO) je glikoproteinski hormon koji kontroliše eritropoiezu, produkciju crvenih krvnih zrnaca. On je citokin (proteinski signalni molekul) za prekursore eritrocita u koštanoj srži. Ljudski EPO ima molekulsku težinu od 34,000. Eritropoietin proizvode interstinalni fibroblasti u bubrezima zajedno sa peritubularnim kapilarima i tubularnim epitelnim ćelijama. On se takođe formira u perisinusoidnim ćelijama u jetri. Dok je produkcija u jetri predominantna u fetalnom i perinatalnom periodu, renalna produkcija je predominantna kod odraslih osoba. Eritropoietin je hormon koji prvenstveno reguliše produkciju crvenih krvnih zrnaca, ali ima i niz drugih bioloških funkcija. Na primer on učestvuje u moždanom odgovoru na povredu neurona.[1] EPO takođe učestvuje u procesu zarastanja rana.[2] ...
