Babesia orientalis is the causative agent of babesiosis in water buffalo (Bubalus babalis, Linnaeus, 1758). In this study, a TaqMan real-time PCR assay was developed for quantitative detection of B. orientalis in water buffalo. Hybridization probe and oligonucleotide primers were designed based on the v4 region of 18S rRNA gene. Detection limit was determined at 2 parasites. Blood samples were collected from experimentally infected water buffalo, as well as from 180 field samples, which were collected from 4 different geographical locations to the north and south of the Yangtse River. The parasite was detected by real-time PCR on day 2 until day 39 post-infection, while reverse line blot (RLB) was on day 6 until day 36 in experimentally infected water buffalo. For the results of 180 field samples, statistical analysis showed no significant difference in relative effectiveness of real-time PCR and RLB. The analysis also indicated that there was no difference in the prevalence of B. orientalis between the regions of south and north of the Yangtse River by both the real-time PCR assay and RLB detection. These results indicated that the parasite infection has spread to the north of the Yangtse River.

Hypervirulent Klebsiella pneumoniae (hvKP) pose significant challenges to clinical anti-infective treatment and has emerged as a major threat to global public health. In this study, we employed the loop-mediated isothermal amplification (LAMP) assays with OTG (orange to green) visual dye and multiplex quantitative real-time PCR (qRT-PCR) assay to rapidly detect hvKP. We determined the detection limits of the LAMP methods for K.

We determined the frequency, genotypes, phenotypes, and mobility of extended-spectrum β-lactamase (ESBL)-encoding genes in Enterobacteriaceae isolated from retail seafood products. Overall, 288 samples of fresh shrimps, catfish and seabass imported from Asia were collected from three supermarket chains in the UK (96 each). After enrichment in MacConkey broth supplemented with cefotaxime, total DNA was screened for the presence of CTX-M, SHV and TEM by real-time PCR.

The increasing frequency of cyanobacterial blooms, particularly those induced by Microcystis aeruginosa (M. aeruginosa), poses severe economic, ecological and health challenges due to the production of microcystins (MCs). Environmental parameters such as light and nutrient availability influence MCs production, while the role of dissolved organic matter (DOM) photochemical processes in regulating these remains unclear.

Introduction: Nakaseomyces glabratus is considered a high priority of attention according to WHO, and also is an important yeast species due to its high rate of intrinsic/acquired resistance against fluconazole. This study aimed at the possible mechanisms of action of thymol, as the promising new antifungal agent, in N. glabratus.

Unlabelled: Hepatitis E virus (HEV) is a globally prevalent zoonotic pathogen that is primarily spread through the fecal-oral route, such as by consuming undercooked or contaminated pork. HEV infection leads to an estimated 3.3 million symptomatic cases of viral hepatitis and 70,000 deaths in human populations each year.
