Background Schistosoma japonicum is a parasitic flatworm that causes human schistosomiasis, which is a significant cause of morbidity in China, the Philippines and *** hupensis (Gastropoda: Pomatiopsidae) is the unique intermediate host ofS. japonicum. A complete genome sequence ofO. hupensis will enable the fundamental understanding of snail biology as well as its co-evolution with theS. japonicum parasite. Assembling a high-quality reference genome ofO. hupehensis will provide data for further research on the snail biology and controlling the spread ofS. *** The draft genome was de novo assembly using the long-read sequencing technology (PacBio Sequel II) and corrected with Illumina sequencing data. Then, using Hi-C sequencing data, the genome was assembled at the chromosomal level. CAFE was used to do analysis of contraction and expansion of the gene family and CodeML module in PAML was used for positive selection analysis in protein coding *** A total length of 1.46 Gb high-qualityO. hupensis genome with 17 unique full-length chromosomes (2n = 34) of the individual including a contig N50 of 1.35 Mb and a scaffold N50 of 75.08 Mb. Additionally, 95.03% of these contig sequences were anchored in 17 chromosomes. After scanning the assembled genome, a total of 30,604 protein-coding genes were predicted. Among them, 86.67% were functionally annotated. Further phylogenetic analysis revealed thatO. hupensis was separated from a common ancestor ofPomacea canaliculata andBellamya purificata approximately 170 million years ago. Comparing the genome ofO. hupensis with its most recent common ancestor, it showed 266 significantly expanded and 58 significantly contracted gene families (P < 0.05). Functional enrichment of the expanded gene families indicated that they were mainly involved with intracellular, DNA-mediated transposition, DNA integration and transposase *** Integrated use of multiple sequencing technol

Cooperation and networking are powerful tools in the combating against tropical diseases. Cooperation on a global scale is essential due to the transboundary nature of tropical diseases. Networking plays a pivotal role in facilitating such cooperation. Both cooperation and networking can foster innovation in disease control programmes. Collaborative research can lead to the development of new drugs and vaccines, while shared surveillance data can enable the early detection and control of disease epidemics. Therefore, consensus of cooperation and networking has been reached during the 7th Symposium on Surveillance-Response Systems Leading to Tropical Diseases Elimination, which reflected in the two documents, i.e.,Consensus for Transboundary Tropical Diseases Control, andAction Consensus of the Network of WHO Collaborating Centres Related to NTDs. These documents will improve the efforts in the fighting against tropical diseases through collective actions to achieve the United Nations’ Sustainable Development Goals (SDGs).

The incidence of Mycobacterium avium complex pulmonary disease (MACPD) has been globally increasing. The present study aims to provide a comprehensive analysis of clinical characteristics and treatment response among patients in the amazon region of Brazil and conduct a retrospective cohort study at a prominent referral hospital in the State of Par, Brazil, from 2012 to 2020. The M. avium group represented 58.9% of cases, followed by M. intracellulare (35.7%), M. colombiense (3.6%), and M. chimaera (1.8%). The majority of patients (73.2%) were female and with an average age of 63 years. Primary clinical manifestations included persistent cough and sputum production. The Charlson comorbidity index (CCI) averaged 2.47, with 36.3% of patients having a CCI score equal to higher than 3. Notably, over 70% of patients had received treatment for pulmonary tuberculosis before initiating treatment for MAC infection. The fibrocavitary radiologic form was the most prevalent (55.4%), frequently exhibiting a bilateral distribution (53.6%). Antimicrobial susceptibility revealed a significant prevalence of MAC resistance to drugs in the therapeutic regimen. Despite this, most of the patients experienced clinical improvement (50%). In conclusion, this study highlights a higher prevalence of MAC infections among middle-aged women, with a history of pulmonary tuberculosis treatment and presenting the fibrocavitary radiological form was predominant.

Infants exhibit diminished susceptibility to external infections， a phenomenon closely linked to the pervasive presence of the bifidobacterial community within their intestinal tract. Nonetheless， a significant knowledge gap remains concerning the distinct species of bifidobacteria initiating anti-infection immune responses during the early developmental stages. In this study， the impact of early intervention with Bifidobacterium bifidum (B. bifidum)， B. breve， and B. longum on neonatal rats infected with Salmonella enterica serovar Typhimurium (S. typhimurium) SL1344 were compared. The study encompasses various immunity levels， including gut immunity， central immunity (thymus)， peripheral immunity (spleen)， and brain immunity. Following Salmonella infection， significant alterations in neonatal rats were observed in growth and developmental levels， immune markers， cytokine levels， balance of T lymphocyte subpopulations， intestinal barrier function， and blood-brain barrier integrity. Compared with B. breve and B. longum， B. bifidum demonstrated more pronounced efficacy in regulating these physiological processes. By conducting multi-level analyses of gut microbiota， bifidobacterial community， colonic content metabolomics， and serum metabolomics， the significance of B. bifidum's role is underscored， and the immune-enhancing function of messenger metabolites is unveiled. Among these metabolites， γ-L-Glutamyl-L-glutamic acid and Orotic acid were found to be shared by all three species， while Hippuric acid and 1a，1b-dihomo Prostaglandin F2α were unique to B. bifidum， and DL-Arginine was specific to B. longum. Overall， this study has provided novel insights into the intervention and immunomodulation by Bifidobacterium in early-life infections， emphasizing the significant role of B. bifidum.
