(b) Monolayers were fixed at days 1 and 5 p.i. and stained for VE-CAD (Alexa488, green) and nuclei (DAPI, blue). 100× magnification showing the presence of giant cMVEC. Scale bars=100 µm. (c) 400× magnification of giant cMVEC at 5 days p.i. with arrows indicating multiple nuclei, asterisks (*) indicate parasite amastigote nests. Scale bars=20 µm.

Visual judgement of turbidity in test tubes containing MHB and viable count. The black line is placed in the background of the test tubes, and it becomes less visible when the MHB in the test tube becomes turbid. In this examination, all the microbiologists judged test tubes A and B as turbid. In contrast, all the microbiologists judged test tubes F, G and H as non-turbid (clear).

(a) Comparison of the alpha diversity of gut microbiota among different groups, presented as the Shannon index reflecting species evenness. Statistical significance between the NM group and CIH group was assessed by Student’s t-test (*P<0.05), while differences between the 0-week and 6-week groups were evaluated using paired sample t-test (†P<0.05). (b) Comparison of the beta diversity of gut microbiota among different groups, presented as PCoA based on Bray–Curtis distances. (c) PERMANOVA analysis (◊◊P<0.01, 999 permutations).

AMPH-B is the most effective agent in combination with MEPM against E. coli-C. albicans dual-species biofilms. Dual-species biofilms were treated with no antimicrobial drugs, only MEPM (50 µg ml−1) or a combination of MEPM (50 µg ml−1) and antifungals such as FLCZ, AMPH-B or MCFG (10 µg ml−1). The survival of E. coli (a) and C. albicans (b) was quantified by selective plating. Data are presented as means±sd from three replicates.

(b) Biofilm formation of P. aeruginosa isolate PsA9 grown in monoculture or together with three pairs of early (AX-1A, AX-3A and AX-5A) and late (AX-1B, AX-3B and AX-5B) A. xylosoxidans isolates. (c) PsA9 was co-cultured with increasing proportions of A. xylosoxidans AX-3A, followed by quantification of biofilm formation. Each dot in the graphs represents the average value of 3 replicates, and bars represent the mean. *P<0.05, **P<0.01.

Fig. 1. Antibacterial activity of C. chinensis and S. officinalis extracts. Gram-negative and Gram-positive bacteria were treated with ethanolic extracts of C. chinensis (a) and S. officinalis (b). MBC was calculated as microgram of non-volatile constituents per millilitre of extract. MBC values of 800 µg ml−1 indicate no antibiotic activity. Error bars denote the standard deviation from three separate experiments.

Fig. 1. Oral microbial diversity in patients with obesity or obesity with AN. (a–d) Microbial alpha diversity was estimated based on ACE (a), observed species (b), Faith’s PD (c) and Shannon (d) indices in the healthy control (n=50), obesity (n=49) and obesity with AN (Ob_AN, n=50) subgroups. Different lowercase letters indicate significant differences (P<0.05). (e–g) Beta diversity of Bray–Curtis (e), Jaccard (f) and unweighted UniFrac (g) distances in the three groups based on PCoA. Different lowercase letters in a–d indicated significant differences (P<0.05).

Fig. 1: dfrA alleles identified from AnTIC and ALTAR E. coli isolates. Analysis shows the total number of each allele identified with each bar split between the trial source (see key for colour). Bioinformatics identified six alleles (Udf=undefined) that could not be grouped with known alleles by association alone. For this study, these were defined as Axx (n=5) and Ayy (n=1).
