We conducted a study in an endemic area of both Oesophagostomum bifurcum and Necator americanus in northern Ghana to examine the possibility of pigs acting as transport hosts for these two human helminth species, due to the commonly observed coprophagic habits of pigs. Under controlled conditions four parasite-free pigs consumed fresh faeces from people heavily infected with both helminths, and faeces were subsequently collected from the rectum of the pigs from 5 to 50 h post-feeding. Four to five per cent of the O. bifurcum and N. americanus eggs fed to the pigs were viable and retrieved as third-stage larvae after coproculture of the pigs' faeces. We discuss the possible impact of the coprophagic habits of pigs as potential parasite transport hosts during different seasons in this area of West Africa.

Bradyrhizobium sp. strain SUTN9-2 demonstrates cell enlargement, increased DNA content, and efficient nitrogen fixation in response to rice (Oryza sativa) extract. This response is attributed to the interaction between the plant's cationic antimicrobial peptides (CAMPs) and the Bradyrhizobium BacA-like transporter (BclA), similar to bacteroid in legume nodules.

To address the challenge of antibiotic-containing wastewater, a novel micromagnetic carrier-modified integrated fixed-film activated sludge system (MC-IFAS) was developed for treating tetracycline (TC)-containing swine wastewater in this study. The magnetic effects of the MC significantly enhanced TC removal by improving TC biosorption and biodegradation in both the suspended activated sludge and the carrier-attached biofilm in the MC-IFAS. The increased electrostatic attraction and number of binding sites in both the activated sludge and the biofilm enhanced their TC biosorption capacities, particularly in the activated sludge.

Amorphous clusters are gaining prominence as prospective hosts for sodium-ion hybrid capacitors (SIHCs), but their efficacy is still affected by atomic coordination. Optimization of ion storage and charge transport can be achieved through high coordination and bimetallic configurations. Herein, high-coordination amorphous P-Nb-W-P (Nb/W-P) clusters are skillfully tailored by bridging Nb into the second shell of W in the W-P configuration, nested in situ in conductive and stable N, P co-doped carbon nanospheres (Nb/W-P@NPC).

causes life-threatening infections in immunocompromised hosts, including hospitalized neonates. This pathogen is intrinsically resistant to fluconazole, while uncommon strains resistant to multiple antifungal drugs, including voriconazole, amphotericin B, and echinocandins, have also been reported from healthcare environments. Thus, understanding how spread, persist, and adapt to healthcare settings could help us develop better infection management strategies.
