Background. Infections caused by Nocardia spp. can occur in immunocompromised as well as immunocompetent individuals. Although nocardiosis is rare, it is being increasingly recognized owing to the rise in occurrence rate over the years. The documentation of pleural involvement in nocardiosis is rare in India. Case. We report a case of pulmonary nocardiosis in an immunocompromised individual caused by Nocardia otitidiscaviarum. Discussion. Pulmonary nocardiosis caused by Nocardia otitidiscaviarum may go unnoticed without clinical suspicion. Correct and timely identification is the key to proper patient management. Conclusion. Coordination between clinicians and microbiologists is necessary for early diagnosis and appropriate management of nocardiosis.

The infratemporal fossa (ITF) is an anatomically complex cavity that houses a variety of muscular and neurovascular structures at the base of the skull. Infections involving the ITF, though uncommon, can be fatal due to the difficulties of accessing this anatomical space and its proclivity to evolve into a cavernous venous thrombosis (CVT). As a result, a multi-disciplinary approach involving several surgical and medical subspecialists is often warranted. We present a case of an infratemporal fossa abscess (IFA) after wisdom teeth extraction with a very complicated clinical course and a distinct microbiologic profile.

The contamination of pharmaceutical products by micro-organisms poses a significant risk to public health. This study was conducted to detect and characterize micro-organisms associated with unsealed drugs sold in Ihiagwa community in Owerri, Imo State, Nigeria. A variety of microbiological techniques were employed to analyse samples from unsealed drug containers. The identification process involved morphological, biochemical and sugar utilization methods, aiding in the accurate determination of microbial species. Microbial contamination was observed in 42 (84 %) out of 50 samples, with contaminants including bacteria and fungi. The range of contamination is between 1.2±0.01×103 and 2.3±0.02×103 c.f.u. ml−1 for viable count, 0.1±0.02×102 and 0.3±0.01×102 c.f.u. g−1 for coliform count and 0.2±0.01×101 and 0.5±0.01×101 c.f.u. g−1 for fungi count. The identified microbes were Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger. The most common bacterial isolate was S. aureus (51.8 %), while C. albicans (73.3 %) was the most prevalent fungus. Among the pharmacies and healthcare facilities examined, the Uchems pharmacy had the highest proportion of bacterial isolates (37 %), followed by the Stepwise pharmacy (22.2 %), while the lowest proportion was found at the Roseline Health Clinic (7.4 %). The identification of potentially harmful micro-organisms in these unsealed drug container samples emphasizes the importance of stringent quality control measures and improved handling, storage and packaging practices to ensure product safety and efficacy, especially among pharmacetical dealers.

In July 2023, the World Health Organization (WHO) began recommending targeted next-generation sequencing (tNGS), due to its ability to detect resistance to many drugs with a single test. In March 2023, South Africa further adopted the GeneXpert XDR cartridge, which detects mutations associated with resistance to second-line injectable drugs. Here, we consider the feasibility for implementing tNGS in South Africa, what such a facility might look like and the specific context of this upper-middle-income country. Whilst the WHO now recommends tNGS for TB diagnostics and DST, there are many economic and infrastructural challenges opposing its deployment. In lieu of this, we instead recommend a stratified diagnostic pipeline that utilizes South Africa’s existing GeneXpert technologies, attempting to reduce the costs associated with implementation of tNGS.

Xanthomonas euvesicatoria the primary causal agent of bacterial spot of pepper (BSP), poses a significant global challenge, resulting in severe defoliation and yield losses for pepper growers. We present the whole genome sequences of eight X. euvesicatoria strains associated with BSP in Vietnam. These genomes contribute to representation of pepper production regions in the global sample of X. euvesicatoria genomes, enabling the development of precise global disease management strategies.
