Many outbreaks in livestock and humans have reported, the soil and climatic conditions would have supported long-term spore persistence. Hence, the state of Karnataka in India was chosen as an initial pilot site to study, isolate, and characterize Bacillus anthracis. In this study, we integrate molecular typing and soil analysis across endemic and non-endemic areas, an approach that has been scarcely explored and could be a novel contribution. By comparing both endemic and non-endemic regions, it would be an opportunity to examine soil-related ecological factors that could have been linked to the anthrax outbreaks. A total of 45 suspected animal anthrax cases were investigated using culture and PCR-based methods. Colonies with Medusa head-like appearance on blood agar plates were subjected to PCR assays targeting protective antigen (pXO1), capsular gene (pXO2), and the chromosomal rpoB genes. Additionally, soil samples from 12 different sites (six endemic and six non-endemic) were processed using the Ground Anthrax Bacillus Refined Isolation (GABRI) method, which was used to enhance the detection of B. anthracis spores by reducing environmental contaminants that may inhibit spore germination and growth.</p><p><strong>Results: </strong>Out of 45 suspected animal anthrax cases, 09 isolates were confirmed as Bacillus anthracis with colony characteristics of greyish-white, frosted-glass on blood agar, further verified through PCR analysis. Phylogenetic analysis based on the rpoB gene demonstrated a close genetic relationship among these isolates, suggesting that the transmission of spores was localized and likely facilitated by animal movement. The soil analysis showed that the endemic sites had an alkaline pH of 7.81-8.9, higher organic carbon 0.45-4.36 %, elevated phosphorus 10.32 to 123.7 kg/ha, and greater clay content up to 45 % in Bellary, contributing to higher survivability and retention of spores in endemic regions. In contrast, non-endemic soil exhibited neutral to slightly acidic pH (6.1-6.85), lower phosphorus levels, and sandy clay loam texture that may limit long-term spore retention.</p><p><strong>Conclusion: </strong>The study offers significant insights into the environmental and genetic factors contributing to the persistence of Bacillus anthracis in both endemic and non-endemic regions. The finding shows that soil plays a crucial role in the survival and transmission of anthrax spores, with higher retention observed in endemic areas. The close genetic relationship among isolates further suggests localized transmission, likely influenced by animal movement.

Genomic DNA was extracted using three methods: Qiagen DNeasy kit, Zymo bead-based method, and phenol-chloroform extraction. The inclusion of ampicillin during initial incubation in the phenol-chloroform method enhanced DNA yield by selectively eliminating vegetative cells without inducing sporulation.

Phylogenetic analysis with bootstrap replicates revealed conserved sequences in plasmid genes, while rpoB exhibited notable diversity, suggesting chromosomal variation among the isolates.

These changes in part correlated with altered WTA glycosylation patterns as shown by WTA-specific antibodies and for the resistant strain resulted in compromised phage therapy as shown in a Galleria mellonella infection model.

Conidia are used for inoculating the fungus onto French soft cheeses and are produced industrially by submerged fermentation. However, the impact of mycelium macromorphology on conidial production for this type of fermentation has been little investigated. By studying the physiological effect of different sources and concentrations of carbohydrates at the laboratory scale, it was observed that the fungus takes on different morphologies associated with varying ability to produce conidia. Especially, a dispersed morphology was not always associated with production of conidia. Through RNA-seq transcriptomic analyses, we followed the expression profiles of P. camemberti genes during the time course of liquid cultures made in the presence of two concentrations of glucose, one of sucrose and one with a mix of glucose and fructose, which are conditions for which P. camemberti presents varying morphologies and efficiencies to produce conidia. This led to confirm that, like other ascomycetes, P. camemberti likely uses the conidiation pathway first described in the model fungus Aspergillus nidulans. It also enabled the identification of a potential conidiation-inhibiting transcription factor, specific to Eurotiales and only upregulated in conditions without conidia production.
