    garA is required for growth of M . tuberculosis in vitro , survival in macrophages, and virulence in mice. ( A ) M . tuberculosis lacking garA was unable to grow on standard <t>7H10</t> medium unless supplemented with asparagine. Plasmid-borne garA restored the defect, but variants of garA with mutations at threonine 21 in the phosphorylation motif (ETTS) gave only partial complementation. Strains were grown in <t>Middlebrook</t> 7H9 plus 30 mM asparagine then washed and diluted in standard 7H9 and spotted onto standard 7H10 with or without 10 mM asparagine. Photographs are representative of at least 3 independent experiments. ( B ) M . tuberculosis lacking garA (red squares) had a defect in growth and survival in differentiated THP-1 cells compared to parental M . tuberculosis H37Rv (black circles). Re-introduction of GarA (black triangles) or variants of GarA lacking a single phosphorylation site (grey crosses and squares) restored growth but variant GarA lacking both phosphorylation sites (green triangles) did not. Data points show the mean and standard deviation from four replicates and are representative of two independent experiments. ( C ) M . tuberculosis lacking garA was avirulent in mice as it was eliminated from the lungs. BALB/C mice were infected intranasally with 10 5 bacilli and bacterial burden was measured on days 1, 7, 21 and 28. Data points show the bacterial burden in individual animals. The bacterial burden of mice infected with Δ garA Mt (red squares) was significantly lower than those infected with M . tuberculosis H37Rv (black circles), or complemented Δ garA Mt (black triangles) at all time points from day 7 (p

    Effects of euglycaemic and hyperglycaemic culture conditions on H37RV infection and cytokine production in vitro. (A) CD14 + selected monocytes were differentiated into M2 macrophages in the presence of 5 mmol/L glucose, 5 mmol/L glucose and 20 mmol/L mannitol or 25 mmol/L glucose. The macrophages were infected for 1 hour with H37Rv at an MOI of 10. After infection the macrophages were washed and fresh media containing the different glucose media was added. After 24 hours supernatants were collected and the cells were lysed by osmotic pressure. (B) Cell lysates were serially diluted and plated on <t>Middlebrook</t> <t>7H10</t> agar. CFUs were counted after 2–3 weeks of growth at 37°C. Data are shown as mean ± SEM of two independent experiments (n = 4). (C) Pro-inflammatory cytokines TNF-α and IL-6 were measured along with the anti-inflammatory cytokines IL-10 and IL-1RA. Data are shown as mean ± SEM.

MØs were incubated with apocynin or L-NIL for 30 minutes, then infected with Mtb wild-type or Δ( ku,ligD,recA ) for 2 hours (MOI = 10) and washed with HBSS. On the day of infection and after 6 days of culture, MØs were lysed with Triton X-100 and cell lysates were plated onto <t>Middlebrook</t> <t>7H10</t> agar supplemented with 10% OADC. After 21 days of culture, CFUs were counted. Data are presented as fold increase in CFUs, expressed as means ± SEM (n = 5; #p≤0.04, Δ( ku,ligD,recA ) vs. Δ( ku,ligD,recA ) + apocynin or L-NIL; Mann-Whitney U test).

(B) The accumulation of [ 14 C]chenodeoxycholate by M. smegmatis SMR5 (wild type; closed circles) and M. smegmatis MN01 (Δ mspA ; open circles) was measured. Regression analysis yielded uptake rates of 0.09 and 0.03 nmol mg −1 min −1 for 20 μM chenodeoxycholate for the wild-type and mutant strains of M. smegmatis , respectively.

    MspA-dependent sensitivities and permeabilities of M. smegmatis to hydrophobic compounds. (A) The sensitivities of wild-type M. smegmatis (black bars), the Δ mspA mutant (white bars), and the Δ mspA mutant transformed with the mspA expression vector pMN014 (gray bars) to erythromycin were determined by serial dilution in <t>Middlebrook</t> <t>7H10</t> agar (c, concentration). The number of surviving cells was normalized to the number of cells counted on plates without antibiotic for each strain, and the results are expressed as relative CFU (percent CFU). (B) The accumulation of [ 14 C]chenodeoxycholate by M. smegmatis SMR5 (wild type; closed circles) and M. smegmatis MN01 (Δ mspA ; open circles) was measured. Regression analysis yielded uptake rates of 0.09 and 0.03 nmol mg −1 min −1 for 20 μM chenodeoxycholate for the wild-type and mutant strains of M. smegmatis , respectively. The assay was performed at 37°C. The structures of the compounds are shown in the corresponding graphs. The sensitivity and uptake experiments were done in triplicate, and the results are shown with their standard deviations. The asterisks denote the datum points that differed significantly ( P

( A ) M . tuberculosis lacking garA was unable to grow on standard 7H10 medium unless supplemented with asparagine. Plasmid-borne garA restored the defect, but variants of garA with mutations at threonine 21 in the phosphorylation motif (ETTS) gave only partial complementation. Strains were grown in Middlebrook 7H9 plus 30 mM asparagine then washed and diluted in standard 7H9 and spotted onto standard 7H10 with or without 10 mM asparagine. Photographs are representative of at least 3 independent experiments. ( B ) M . tuberculosis lacking garA (red squares) had a defect in growth and survival in differentiated THP-1 cells compared to parental M . tuberculosis H37Rv (black circles). Re-introduction of GarA (black triangles) or variants of GarA lacking a single phosphorylation site (grey crosses and squares) restored growth but variant GarA lacking both phosphorylation sites (green triangles) did not. Data points show the mean and standard deviation from four replicates and are representative of two independent experiments.

(B and C) MØs were infected with Mtb wild-type or its mutants (B) or complemented strains Δ( ku,ligD,recA )- P recA recA – complemented strain I or Δ( ku,ligD,recA )- P kuligD ku-ligD – complemented strain II (C) for 6 days. On the day of infection and after 6 days of culture, MØs were lysed with Triton X-100 and cell lysates were plated onto Middlebrook 7H10 agar supplemented with 10% OADC. After 21 days of culture, CFUs were counted. Data are presented as fold increase in CFUs, expressed as means ± SEM (n = 5; *p≤0.05, Δ( ku,ligD,recA ) vs. wild-type; #p≤0.05, complemented strain I and II vs. Δ( ku,ligD,recA ) Mann-Whitney U test).

    MspA-dependent sensitivities and permeabilities of M. smegmatis to hydrophobic compounds. (A) The sensitivities of wild-type M. smegmatis (black bars), the Δ mspA mutant (white bars), and the Δ mspA mutant transformed with the mspA expression vector pMN014 (gray bars) to erythromycin were determined by serial dilution in Middlebrook 7H10 agar (c, concentration). The number of surviving cells was normalized to the number of cells counted on plates without antibiotic for each strain, and the results are expressed as relative CFU (percent CFU). (B) The accumulation of [ 14 C]chenodeoxycholate by M. smegmatis SMR5 (wild type; closed circles) and M. smegmatis MN01 (Δ mspA ; open circles) was measured. Regression analysis yielded uptake rates of 0.09 and 0.03 nmol mg −1 min −1 for 20 μM chenodeoxycholate for the wild-type and mutant strains of M. smegmatis , respectively. The assay was performed at 37°C. The structures of the compounds are shown in the corresponding graphs. The sensitivity and uptake experiments were done in triplicate, and the results are shown with their standard deviations. The asterisks denote the datum points that differed significantly ( P
