AI Article Synopsis
- Neospora caninum is a protozoan parasite linked to abortions in goats, causing significant economic losses.
- A study was conducted to assess the prevalence of this parasite in Tunisian goats, collecting 121 meat samples and finding a molecular prevalence of 19%.
- The highest prevalence was in goats aged 2-4 years, with the study being the first to provide genetic characterization of N. caninum in North African goats.
Article Abstract
Neospora caninum is an intracellular protozoan parasite from the phylum Apicomplexa, mainly associated with abortions and causing enormous economic losses. We aimed, by the present study, to estimate the molecular prevalence and phylogenetic analyses of natural infection with N. caninum in Tunisian goats. A total number of 121 meat samples were collected from slaughtered goats in the regional slaughterhouse of Béja (Northwest Tunisia) and tested from N. caninum ITS1 gene using PCR followed by sequencing of PCR products. Phylogenetic analyses were used to identify this parasite infecting goats in Nortwest Tunisia. The overall molecular prevalence was 19% (23/121). The highest molecular prevalence of N. caninum was observed in goats aged between 2 and 4 years (31.9 ± 13.27%) (P = 0.004). There was no difference in the overall molecular prevalence of N. caninum according to both localities and animal breeds. Comparison of the partial sequences of the ITS1 gene revealed 99-100% similarity with GenBank sequences. A high similarity with all the blasted genotypes was reported for N. caninum sequences. This is the first molecular study and genetic characterisation of N. caninum in North African goats.

Host-seeking behavior of Culicoides species was examined from 2018 to 2019 in West Bengal, India, which elucidated diel activity, feeding success, attack rate, biting rate, and preferential landing of adult Culicoides on the cattle. A comparative assessment was done between the light trap and the aspirator. The host-seeking experiment involved a substantial timeframe of 297 h of catch collections over 27 nights.

Purpose Of Review: To date, there is relatively limited research investigating changes in red blood cells (RBCs), particularly qualitative changes, in cancer patients and cancer patients receiving treatment. These changes may be important in better understanding cancer-associated anemia, which is the most prevalent hematological disorder in cancer patients with wide-ranging implications on patient care and quality of life. This review aims to summarize available evidence regarding qualitative and quantitative changes in RBCs in individuals with cancer prior to treatment and in patients undergoing treatment.

Objectives: Premature ovarian insufficiency (POI) affects 1 in 10,000 children, with its molecular causes largely unknown. Adult studies suggest that low androgen levels induce ovarian insufficiency, but data on about this in children is limited. This study aims to assess the prevalence of low androgen levels in childhood POI and its relationship with adrenal insufficiency.

Importance: Recently, the US Food and Drug Administration gave premarketing approval to an algorithm based on its purported ability to identify individuals at genetic risk for opioid use disorder (OUD). However, the clinical utility of the candidate genetic variants included in the algorithm has not been independently demonstrated.
Objective: To assess the utility of 15 genetic variants from an algorithm intended to predict OUD risk.

Importance: Although differences in the prevalence of key cancer-specific somatic mutations as a function of genetic ancestry among patients with cancer has been well-established, few studies have addressed the practical clinical implications of these differences for the growing number of biomarker-driven treatments.
Objective: To determine if the approval of precision oncology therapies has benefited patients with cancer from various ancestral backgrounds equally over time.
Design, Setting, And Participants: A retrospective analysis of samples from patients with solid cancers who underwent clinical sequencing using the integrated mutation profiling of actionable cancer targets (MSK-IMPACT) assay between January 2014 and December 2022 was carried out.
