Summary Conventional wastewater treatment relies on a complex microbiota; however, much of this community is still to be characterized. To better understand the origin, dynamics and fate of bacteria within a wastewater treatment plant: untreated primary wastewater, activated sludge and post‐treatment effluent were characterized. From 3163 exact sequence variants (ESVs), 860 were annotated to species‐level. In primary wastewater, 28% of ESVs were putative bacterial species previously associated with humans, 14% with animals and 5% as common to the environment. Differential abundance analysis revealed significant relative reductions in ESVs from potentially human‐associated species from primary wastewater to activated sludge, and significant increases in ESVs from species associated with nutrient cycling. Between primary wastewater and effluent, 51% of ESVs from human‐associated species did not significantly differ, and species such as Bacteroides massiliensis and Bacteroides dorei increased. These findings illustrate that activated sludge increased extracellular protease and urease‐producing species, ammonia and nitrite oxidizers, denitrifiers and specific phosphorus accumulators. Although many human‐associated species declined, some persisted in effluent, including strains of potential health or environmental concern. Species‐level microbial assessment may be useful for understanding variation in wastewater treatment efficiency as well as for monitoring the release of microbes into surface water and the wider ecosystem.

“…skin and blood). Moraxella species, including Moraxella osloensis, are recognised as common bacterial inhabitants of mucosal surfaces and have been isolated from the respiratory tracts of a range of mammalian hosts 46 and from multiple environmental sources 47 . Thus, the predominance of Rothia amarae, Enhydrobacter aerosaccus and Moraxella osloensis in the elephants' trunks is unsurprising, as the trunk represents a unique interface between the animal's upper respiratory tract and its environment, given its function in breathing, feeding, olfactory perception and tactile exploration 48 .…”

Hypervariable region sequencing of the 16S rRNA gene plays a critical role in microbial ecology, offering insights into bacterial communities within specific niches. While providing valuable genuslevel information, its reliance on limited genetic data from targeted regions of this gene limits its overall utility. Advances in sequencing have enabled characterisation of the full-length 16S rRNA gene, enhancing species-level classification. Third-generation sequencing technologies can sequence genes in single reads, yet challenges in cost and accessibility persist. Although Illumina's short-read platforms are cost-effective and precise, they lack full-length 16S rRNA amplicon sequencing capability. This study aimed to evaluate the feasibility of a modified 150 bp paired-end 16S rRNA amplicon shortread sequencing technique on the Illumina iSeq 100 by utilising a mock microbial community and subsequently performing exploratory characterisation of captive (zoo) and free-ranging African elephant (Loxodonta africana) respiratory microbiota. Our findings support the viability of the sequencing technique through taxonomic assignment that is consistent with the microbial standard’s theoretical composition. Tentative bacterial signatures, potentially representative of distinct respiratory tract compartments (trunk and lower respiratory tract) were observed, necessitating further investigation with larger sample sizes to gain deeper insights into its implication for elephant physiology and health.

Nocardia causes rare opportunistic infections, that can be challenging to diagnose because of atypical features on conventional microbiological identification techniques. Immunosuppressed patients are more susceptible to infections from Nocardia and are associated with multi-organ involvement. We report a case of a 63-year-old male who developed peritonitis from Nocardia farcinica that rarely causes infections in humans. The nonspecific symptoms, negative blood cultures, and slow growth can make diagnosis difficult. Despite aggressive therapy, the virulence and inherent resistance to the antibiotics can result in high mortality from Nocardia farcinica infections.
