“…Susceptibility to different antibiotics was determined using minimum inhibitory concentration test strips on Mueller-Hinton agar (not the broth method recommended by CLSI). The results showed that the four strains were susceptible to ampicillin, azithromycin, aztreonam, chloramphenicol, erythromycin, fosfomycin, rifampicin, tetracycline and trimethoprim, which is in contrast to the patterns of M. aurum NCTC 10437 T (resistant to rifampicin, troleandomycin and vancomycin), M. austroafricanum CCUG 37667 T (resistant to troleandomycin and vancomycin), M. monacense JCM 15658 T (B9-21-178 T in [33]; variable to trimethoprim-sulfamethoxazole), M. murale JCM 13392 T (resistant to ceftazidime, chloramphenicol and penicillin G) and M. sarraceniae JCM 30395 T (resistant to aztreonam and trimethoprim) [12,[33][34][35].…”

Four bacterial strains (LJ126T/S18 and Z-34T/S20) recovered from faecal samples of Tibetan antelopes on the Qinghai–Tibet Plateau of China were analysed using a polyphasic approach. All four isolates were aerobic, short rod-shaped, non-motile, Gram-stain-positive, acid-fast and fast-growing. Phylogenetic analyses based upon 16S rRNA and whole-genome sequences showed that the two pair of strains formed two distinct branches within the evolutionary radiation of the genus Mycolicibacterium . Strains LJ126T/S18 and Z-34T/S20 were most closely related to Mycolicibacterium austroafricanum CCUG 37667T, Mycobacterium aurum NCTC 10437T, Mycobacterium pyrenivorans DSM 44605T, Mycobacterium monacense JCM 15658T, Mycolicibacterium sarraceniae JCM 30395T, Mycolicibacterium tokaiense JCM 6373T and Mycobacterium murale JCM 13392T, but readily distinguished from the known species by a combination of chemotaxonomic and phenotypic features and by low average nucleotide identity values (74.4–84.9 %). Consequently, the two strain pairs are considered to represent different novel species of Mycolicibacterium for which the names Mycolicibacterium baixiangningiae sp. nov. and Mycolicibacterium mengxianglii sp. nov. are proposed, with LJ126T (=CGMCC 1.1992T=KCTC 49535T) and Z-34T (=CGMCC 1.1993T=DSM 106172T) as the respective type strains.

“…The genus Mycobacterium was divided into five genera, including an emended genus Mycobacterium , and four novel genera, namely, Mycolicibacterium gen. nov., Mycolicibacter gen. nov., Mycolicibacillus gen. nov., and Mycobacteroides gen. nov. by Gupta et al ( 2018 ) on the basis of phylogenomic and comparative genomic studies of 150 out of 188 type strains. Moreover, there were other novel species belonging to the genus Mycobacterium being published (Nouioui et al, 2018 ) at the same time. Therefore, the taxonomic statuses of more than 38 species belonging to the emended genus Mycobacterium must be confirmed.…”

In eutrophic water, attached bacteria of Microcystis play an important role in the formation, development, and degradation of Microcystis blooms. A novel actinobacterium, designated as JXJ CY 35T, was isolated from the culture mass of Microcystis aeruginosa FACHB-905 (Maf) collected from Lake Dianchi, Yunnan Province, China. Strain JXJ CY 35T was gram-positive, acid-fast staining, aerobic, with short rod-shaped cells, positive for catalase, and negative for oxidase. The isolate was able to grow at 10.0–36.0°C, pH 4.0–10.0, and tolerate up to 5.0% (w/v) NaCl, with optimal growth at 28°C, pH 7.0–8.0, and 0% (w/v) NaCl. Cell-wall peptidoglycan contains aspartic acid, glutamic acid, glycine, and alanine, with mannose, ribose, galactose, and arabinose as whole-cell sugars. Polar lipids consist of diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), glycolipid (GL1-3), phosphoglycolipid (PGL), phosphatidylinositol (PI), and unidentified lipid (L1). The predominant menaquinone was MK-9. Major fatty acids (>10%) were C17:1ω7c (37.0%) and C18:1ω9c (18.9%). The complete genome sequence of strain JXJ CY 35T was 6,138,096 bp in size with a DNA G + C content of 68.3%. Based on 16S rRNA gene sequences, it has 98.2% similarity to Mycolicibacterium arabiense JCM 18538T. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values between strain JXJ CY 35T and the closest five type strains M. arabiense JCM 18538T, M. goodii ATCC 700504T, M. mageritense DSM 44476T, M. austroafricanum DSM 44191T, and Mycobacterium neglectum CECT 8778T were 52.1, 20.3, 20.3, 20.6, and 19.8%, and 92.7, 75.5, 75.6, 76.0, and 75.2%, respectively. On the basis of the above taxonomic data and differences in physiological characteristics from the closely related type strain, strain JXJ CY 35T was determined to represent a novel species of genus Mycolicibacterium, for which the name Mycolicibacterium lacusdiani sp. nov., is proposed. The type strain is JXJ CY 35T (=KCTC 49379T = CGMCC 1.17501T). Different inoculation dosages of the type strain JXJ CY 35T could exhibit different effects on the growth of Maf and its toxin synthesis and release. Strain JXJ CY 35T could promote the growth of Maf by providing it with available phosphorus, nitrogen, probably vitamins, and plant growth hormones.

“…3 The bacteriological analysis of healthy goats in this study revealed that goats could harbor a variety of zoonotic pathogens in their intestines during their growth, especially in the pre-weaning stage. These zoonotic bacteria mainly include the previous reported Lactococcus garvieae, 8 Helicobacter pylori, 8,9 Klebsiella pneumoniae, 10 Shigella sonnei, 11 Shigella boydii, 12 Campylobacter coli, 13 Salmonella enterica, 14 Acinetobacter baumannii, 15 Shigella flexneri, 12 Shigella dysenteriae, 12 Clostridium perfringens, 16 Campylobacter jejuni, 13 Campylobacter lanienae, 17 Salmonella bongori, 18 Campylobacter fetus, 19,20 Listeria monocytogenes, 21 Acinetobacter haemolyticus, 22 Mycobacterium tuberculosis, 23 Mycobacterium neglectum, 24 and Burkholderia pseudomallei. 25 The results suggest that goats may act as a reservoir for many zoonotic bacteria.…”

The risk of zoonosis transmission when handling livestock or animal products is substantial, ‘One Health’ interventions should be an effective strategy for the control of many zoonotic bacteria. In this study, 26 fresh fecal samples from 2 clinically healthy goats were collected at different day ages to survey goat-borne zoonotic bacterial infection, and 19 fresh fecal samples from diarrhetic goats were tested to evaluate the possible role of zoonotic pathogens in goat diarrhea. Following all samples were analyzed by Metagenomic Sequencing, a total of 20 kinds of zoonotic bacteria were screened from healthy goats, and 11 (55%) of them were infection mainly during the preweaned period. Of the 19 fresh fecal samples from diarrhetic goats, all were confirmed to be zoonotic bacterial infection positive (range from 11 to 12 species). After comparison with healthy samples of the same or similar day-age goats, it was found that Lactococcus garvieae, Helicobacter pylori, Klebsiella pneumoniae, Shigella sonnei, Shigella boydii, Campylobacter coli, Salmonella enterica, Acinetobacter baumannii, Shigella flexneri, Shigella dysenteriae and Clostridium perfringens and Campylobacter fetus were highly increased incases in some diarrheic cases, while the remains had no significant change. The results suggest that goats may act as a reservoir for many zoonotic bacteria, and some of them may be associated with goat intestinal inflammation.
