The main objective of this study was to describe the trend in the distribution of HCV genotypes and subtypes from 2013 to 2023 in the Cameroonian population. Viral loads were determined using the Abbott real-time assay, and genotyping/subtyping was based on nested and semi-nested reverse transcription polymerase chain reaction (RT-PCR) amplification of the regions encoding the core and non-structural protein 5B (NS5B) regions, respectively, followed by sequencing and phylogenetic analysis. A total of 512 patients with NS5B and core sequencing results were included in our study. Genotyping revealed a predominance of both genotype 4 (38.48%) and genotype 1 (37.11%), followed by genotype 2, detected in 22.46% of patients. Interestingly, 10 samples (1.95%) had discordant genotypes in both regions, suggesting the presence of putative recombinant forms of HCV. Twelve different subtypes were detected during the study period, with a predominance of subtypes 4f (18.95%) and 1e (16.02%). Furthermore, phylogenetic analysis failed to assign a subtype to a relatively high proportion of sequences (38.67%) for the two genomic regions, and their classification was limited to genotype assignment.

In this study, we identified three double-stranded RNA (dsRNA) viruses coinfecting a strain of <i>Conidiobolus taihushanensis</i>. These viruses were identified as Conidiobolus taihushanensis totivirus 1 (CtTV1), Conidiobolus nonsegmented RNA virus 1–2 (CNRV1-2), and Conidiobolus taihushanensis virus 1 (CtV1). Through high-throughput sequencing and RNA-ligase-mediated rapid amplification of cDNA ends (RLM-RACE), we determined their complete genome sequences. The genome of CtTV1 is 6,921 nucleotides in length, containing two open reading frames (ORFs). ORF1 encodes a 1,124-amino-acid capsid protein (CP) with a molecular weight of 125.07 kDa, and ORF2 encodes a 780-amino-acid RNA-dependent RNA polymerase (RdRp) with a molecular weight of 88.05 kDa. CNRV1-2, approximately 3.0 kb in length, also contains two ORFs, which are predicted to encode a 186-amino-acid hypothetical protein (HP) and a 758-amino-acid RdRp. CtV1 has a smaller genome consisting of 3,081 base pairs (bp) with two ORFs: one encoding a 244-amino-acid HP (26.85 kDa) and the other encoding a 707-amino-acid RdRp (80.64 kDa). Phylogenetic analysis based on RdRp sequences revealed that CtTV1 shows the highest similarity to Phytophthora pluvialis RNA virus 1, with 38.79% sequence identity, and clusters with members of the family <i>Orthototiviridae</i>, and it is most closely related to Utsjoki toti-like virus. In contrast, CtV1 formed a unique branch and might represent a new genus. The genome sequence of CNRV1-2 is 99.74% identical to that of the previously described Conidiobolus non-segmented RNA virus 1 (CNRV1). Our findings indicate that CtTV1 and CtV1 are distinct novel viruses, while CNRV1-2 appears to be a variant of CNRV1.
