The development of a rapid, sensitive, specific method for detecting foodborne pathogens is paramount for supplying safe food to enhance public health safety. Despite the significant improvement in pathogen detection methods, key issues are still associated with rapid methods, such as distinguishing living cells from dead, the pathogenic potential or health risk of the analyte at the time of consumption, the detection limit, and the sample-to-result. Mammalian cell-based assays analyze pathogens’ interaction with host cells and are responsive only to live pathogens or active toxins. In this study, a human embryonic kidney (HEK293) cell line expressing Toll-Like Receptor 5 (TLR-5) …

The human respiratory and circulatory systems collaborate intricately to ensure oxygen delivery to all cells, which is vital for ATP production and maintaining physiological functions and structures. During limited oxygen availability, hypoxia-inducible factors (HIFs) are stabilized and play a fundamental role in maintaining cellular processes for hypoxia adaptation. First discovered during investigations of erythropoietin production regulation, HIFs influence physiological and pathological processes, including development, inflammation, wound healing, and cancer. HIFs promote extracellular adenosine signaling by enhancing adenosine generation and receptor signaling, representing an endogenous feedback mechanism that curbs excessive inflammation, supports injury resolution, and enhances hypoxia tolerance. This is especially …

Digital Journal of Clinical Medicine
Azathioprine is a pro-drug and is metabolized by the TPMT enzyme in the body. In South Asians, Azathioprine is known to cause alopecia and bone marrow suppression in patients with TPMT enzyme deficiency. In India, the prevalence of TPMT mutation varies from 1.2- 10%. A new mutation was detected in 2014, NUDT15 whose incidence varies from 8.5-16%. Patients with mutation in both TPMT and NUDT15 develop myelosuppression faster. In our case, alopecia manifested as the first clinical feature of Azathioprine myelosuppression. Physicians need to recognize early clinical clues (alopecia) to avoid the impending development of myelosuppression and to look for …

The Balm Framework Of Clinical Excellence: An Adoptable Model For Sub-Saharan Africa., Taoreed Adegoke Azeez
Digital Journal of Clinical Medicine
Clinical excellence is the ability to provide rigorous, evidence-based, and rewarding care to the right patients. The BALM (brilliance, attitude, leadership, and materials) framework is a novel model for adjudicating clinical excellence. There are a few models and frameworks for evaluating clinical excellence, but each has its flaws and does not consider the peculiarities of economically-challenged regions such as sub-Saharan Africa. Coincidentally, such low-resource areas have an urgent need for a framework to assess clinical excellence because of their low health-related indices. The five-step mode of professional excellence is a well-recognised tool and was the model upon which the BALM …

Sneathia vaginalis (Sv) is a gram-negative anaerobic bacterium associated with adverse reproductive outcomes. Sv can traverse the fetal membrane and damage epithelial cells in vitro by producing a pore-forming cytotoxin, cytopathogenic toxin A (CptA). To further understand the transition of Sv from normal flora to a pathogen, an animal in vivo model needs to be created to observe the preliminary ascending infection before we begin to study the effects on pregnancy. Experimentation was conducted to optimize mouse breed, bacteria administration methods, and other variables that arise when working in vivo. The C57BL/6 mouse strain displayed the most consistent …

Tsetse flies and trypanosomosis significantly impact bovine production and human health in sub-Saharan Africa, exacerbating underdevelopment, malnutrition, and poverty. Despite various control strategies, long-term success has been limited. This study evaluates the combined use of entomopathogenic fungi (EPF) and the sterile insect technique (SIT) to combat tsetse flies. Eleven EPF isolates were tested against teneral males of Glossina pallidipes, focusing on mortality rates, radial growth, and impacts on fly fitness. Temperature effects on conidial growth, sporulation, and spore yield of SIT-compatible/tolerant strains were also assessed. The fungal isolates significantly influenced mortality rates in both unirradiated and irradiated (SIT-treated) males (p < 0.0001). Metarhizium anisopliae strains ICIPE 20, ICIPE 32, ICIPE 41, ICIPE 62, ICIPE 78, and Beauveria bassiana ICIPE 603 showed higher SIT compatibility/tolerance with LT50 values of 11–30 days, compared to other more virulent isolates with LT50 values of 4–9 days. Temperature significantly affected the radial growth of SIT-compatible EPF strains (p < 0.0001), with M. anisopliae ICIPE 78 exhibiting the fastest conidia growth at 25°C. Spore yield varied significantly across temperatures (15–40°C), and the thermal range for conidia germination of SIT-compatible strains was 8.1–45.4°C, with an optimal range of 26.7–31.1°C. Moreover, infected unirradiated females and irradiated males (donors) successfully transmitted conidia to untreated flies (receivers) without significant differences in survival rates (p = 0.6438) and no observed sex dimorphism. Our findings highlight the potential of combining EPF and SIT as a novel dual approach that could effectively and synergistically suppress tsetse fly populations.

Background: Tick-borne pathogen (TBP) surveillance studies often use whole-tick homogenates when inferring tick-pathogen associations. However, localized TBP infections within tick tissues (saliva, hemolymph, salivary glands, and midgut) can inform pathogen transmission mechanisms and are key to disentangling pathogen detection from vector competence. Methods: We screened 278 camel blood samples and 504 tick tissue samples derived from 126 camel ticks sampled in two Kenyan counties (Laikipia and Marsabit) for Anaplasma, Ehrlichia, Coxiella, Rickettsia, Theileria, and Babesia by PCR-HRM analysis. Results: Candidatus Anaplasma camelii infections were common in camels (91%), but absent in all samples from Rhipicephalus pulchellus, Amblyomma gemma, Hyalomma dromedarii, …

The aquaculture industry is a big part of the global economy, supplying food and supporting many livelihoods, yet it faces formidable challenges from diverse aquatic pathogens, especially viruses. Effective antiviral treatments are lacking for both humans and economically significant farmed fish like rainbow trout (Oncorhynchus mykiss). When viruses invade host cells, pattern recognition receptors detect viral components, initiating intracellular signaling and type I interferon (IFN-I) production. IFN-I triggers interferon-stimulated genes (ISGs) that establish an antiviral state in infected and nearby cells, curbing viral spread. In rainbow trout, a particularly understudied ISG is viral hemorrhagic septicemia virus (VHSV)-induced gene 3 (vig-3), …
