Dung samples were collected from dairy calves of south Indian states viz., Andhra Pradesh, Karnataka, Kerala, Tamil Nadu and union territory, Puducherry and are subjected to nested polymerase chain reaction (PCR) targeting 18S rRNA gene for detection of Cryptosporidium infection. Of the 459 dung samples screened 182 were found positive with a prevalence of(More)
Extracellular accumulations of Aβ, hyperphosphorylation of tau and intracellular neurofibrillary tangle formation have been the hallmarks of Alzheimer’s Disease (AD). Although tau and its phosphorylation play a pivotal role in the normal physiology yet its hyperphosphorylation has been a pathological manifestation in neurodegenerative disorders like AD. In(More)
The effects of l-ascorbic acid on the frequency of micronuclei induced by model mutagens, cyclophosphamide (CP), mitomycin-C (MMC) and bleomycin (BLM) hydrochloride were tested using mouse bone marrow. Three doses of ascorbic acid (AsA) viz., 10, 30 and 60 mg/kg b.w. were tested for anticlastogenic effects. The doses of positive mutagens used were, CP-50(More)
Alzheimer's disease (AD) has long been characterized primarily by extracellular deposition of Aβ protein. It is a genetically intricate neurodegenerative disorder. Presenilins (PSs) (presenilin 1 [ PS1] and presenilin 2 [PS2]) and apolipoprotein E (APOE) ε4 allele have been found to be potentially linked to Aβ accumulation and accrual in turn contributing(More)
Despite the crucial role of redox active metals like copper and iron in central biological reactions, their elevated levels are involved in the pathogenesis of Alzheimer's Disease (AD). Similarly reactive oxygen/nitrogen species (ROS/RNS) produced during normal metabolic activities, specifically oxidative phosphorylation of the cell, are scavenged by(More)
Babesia bigemina infection was diagnosed in a 14-day old Jersey female calf. The infected calf showed clinical symptoms of high fever, increased respiratory rate, pale conjunctival mucous membrane and haemoglobinuria. Blood smears were prepared and subjected for Giemsas staining method. Microscopic examination of the stained blood smear confirmed the(More)
Sarcocystis species are the obligate tissue protozoan parasites of livestock causing clinical and subclinical disease resulting in downgrading of the meat and their products thereby leading to economic losses. The present study reveals the prevalence and distribution of sarcocystosis in water buffaloes (Bubalus bubalis) slaughtered at local abattoirs in A.P(More)
An investigation was undertaken to study, for the first time, in vitro acaricidal activity of green silver nanoparticles on deltamethrin resistance Rhipicephalus (Boophilus) microplus. The compounds tested were neem coated silver nanoparticles (N-Ag NPs), deltamethrin neem coated silver nanoparticles (DN-Ag NPs), 2, 3 dehydrosalannol (2,3 DHS), 2, 3 DHS(More)
The objectives of the present study were to report the influence of factors like age, sex, breed, dung consistency and rearing system on prevalence of Cryptosporidium spp. in south Indian cattle. Two-step nested PCR was employed for detection of Cryptosporidium infection in dairy calves of south Indian states viz., Andhra Pradesh, Karnataka, Kerala, Tamil(More)
The utility of green silver nanoparticles (AgNPs) in veterinary medicine is steadily increasing as they have many therapeutic applications against pathogens and arthropods of livestock. In this study, green AgNPs using neem (N-AgNPs), 2,3-dehydrosalanol (2,3-DHS-AgNPs) and quercetin dihydrate (QDH-AgNPs) were synthesised and characterised. Synthesised(More)
