Application of a modified human enzyme-linked immunosorbent assay kit for diagnosis of hydatidosis in sheep

Cystic hydatid disease (hydatidosis) is one of the most important zoonosis that is caused by the larval stage of Echinococcus granulosus . As its diagnosis by clinical symptoms alone is difficult and confusing, serologic diagnostic techniques are used to confirm the disease. These techniques can also be used for   epidemiologic studies. The present study was performed with a commercial human en...

Molecular cloning, sequence analysis, and expression in Escherichia coli of the cDNA for guanidinoacetate methyltransferase from rat liver.

Five cDNA clones encoding rat liver guanidinoacetate methyltransferase (S-adenosyl-L-methionine: guanidinoacetate N-methyltransferase, EC 2.1.1.2) were isolated from a lambda gt11 cDNA library by use of a polyclonal antibody to the purified enzyme. Sequence analysis of the longest cDNA indicated that it consisted of 711 base pairs (bp) of coding region, 51 bp of 5' noncoding region, and 162 bp ...

Development of a Latex Agglutination Method for Diagnosis of Rotavirus Infections

Background: Rotavirus is a major cause of morbidity and mortality among children with gastroenteritis. Since the discovery of rotaviruses, several techniques have been used for their laboratory diagnosis; those included Electron Microscopy (EM) and enzyme immunoassay. These methods, however, are expensive and not readily available everywhere. We have developed a technique which can be used for ...

Guanidinoacetate methyltransferase (GAMT) deficiency: a rare but treatable epilepsy.

Epilepsy commonly presents in childhood as part of a syndrome, and some such children may reach adult services without an underlying syndromic diagnosis. For adult neurologists taking over their care, it is often unclear how hard to search for an underlying diagnosis. The diagnostic yield may be small and such a diagnosis may not change management. Young adults with learning difficulties are al...
