AI Article Synopsis
- - The study aimed to identify the species, hosts, and infection rates of a particular parasite in Zhenghe County, Fujian Province, to locate local infection hotspots.
- - Examination of 4,890 snails revealed a low cercariae infection rate of 0.10%, while 34 crabs showed a significantly higher infection rate of 85.29% for a new species serving as a second intermediate host.
- - Findings indicate a substantial infection presence of the studied parasite in the eastern region of Zhenghe County, highlighting potential public health concerns.
Article Abstract
Objective: To investigate the species and hosts of and its infection rate in eastern part of Zhenghe County, Fujian Province, so as to determine the local foci of .
Methods: The snails, crabs and stools of wild cats were collected for the examinations of cercariae, metacercariae and eggs of . The geographical and environmental conditions of the areas were also investigated.
Results: A total of 4 890 snails and 1 035 snails were examined, and the cercariae of were only found in , with an infection rate of 0.10% (5/4 890). sp. nov. as the second intermediate host of , were examined, and the infection rate was 85.29% (29/34) and the average numbers of metacercariae per crab and per gram of crab tissues were 3.85 and 0.62, respectively. Thirty-six crabs, as the second intermediate host of , were examined, and the infection rate was 38.89% (14/36) and the average numbers of metacercariae per crab and per gram of crab tissues were 6.43 and 0.03, respectively. The eggs of were detected in 1 of 2 muck specimens of wild cats.
Conclusions: The data suggest that there is a focus of middle-to-high level of infection caused by and in the eastern part of Zhenghe County.

Objectives: Delayed diagnosis of patients with Fever of Unknown Origin has long been a daunting clinical challenge. Onco-mNGS, which can accurately diagnose infectious agents and identify suspected tumor signatures by analyzing host chromosome copy number changes, has been widely used to assist identifying complex etiologies. However, the application of Onco-mNGS to improve FUO etiological screening has never been studied before.

To assess the impact of the SARS-CoV-2 booster dose on the immune response against COVID-19, we conducted a cross-sectional study in the Casablanca-Settat region of Morocco. The study included 2,802 participants from 16 provinces, all of whom had received three doses of a SARS-CoV-2 vaccine. IgG antibodies targeting the S1 RBD subunit of the SARS-CoV-2 spike protein were quantified using the SARS-CoV-2 IgG II Quant assay and measured on the Abbott Architect i2000SR instrument.
