Background: Leptospirosis is a zoonotic bacterial disease causing abortion, stillbirths and loss of milk production in livestock resulting huge economic losses. cattle has been under-reported under-diagnosed India due to non-specific symptoms, complex laboratory tests, fastidious nature bacterium lack proper diagnostic facilities. Scanty data pertaining epidemiological status leptospirosis avai...

indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of h. contortus. plate elisa was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. indirect plate elisa was able to demonstrate...

Leptospirosis is worldwide zoonotic disease that is serious problem in south Indian states and now emerging in North India. The focus these days is to develop recombinant outer membrane protein based Enzyme-linked immunosorbent assay (ELISA) for seroprevalence of leptospirosis. The aim of this study was to evaluate indirect ELISA based on recombinant LipL41, Loa22, LipL21, LipL32 and OmpL1 prot...

the purpose of this study was to determine the prevalence of bovine leukemia virus (blv) in khorasan razavi and khorasan shomali provinces which are the main provinces located in the northeast of iran. total number of 429 blood samples were collected from industrial dairy herds. the samples were categorized based on province, age (2-3, 4-6, and 7-10 years old), calving (≤ 2, 3-5, and > 5) and h...

BACKGROUND In late 2011, a new Orthobunyavirus of the Simbu serogroup named Schmallenberg virus (SBV) emerged in continental Europe. The virus is transmitted by hematophagous arthropods, with the Culicoides species as, so far known, main vectors. Infection with the virus can cause clinical signs in adult ruminants including diarrhea, fever and reduced milk production. Transplacental infection o...

The specificity and sensitivity of indirect ELISA, based on the use of four different antigenic extracts obtained from a clinical isolate of Salmonella enteritidis, were compared with those obtained with the gm-flagellin based ELISA (IDEXX). A total of 116 serum samples from salmonellae free, naturally infected and vaccinated hens were studied. The results showed that the indirect ELISA, based ...
