Mycobactins and Exochelins of Mycobacterium tuberculosis, M. bovis, M. africanum and Other Related Species [PDF]

Microbiology, 1988
Following iron-deficient growth, mycobactins and exochelins were isolated from 11 strains of Mycobacterium tuberculosis (including type strains of the virulent H37Rv and avirulent H37Ra organisms) as well as from M. bovis (one strain), M. bovis BCG (two strains), M. africanum (eight strains) and M. xenopi (one strain) but not from M.

Morphological and Molecular Characterization of Eimeria saudiensis From Arabian Oryx (Oryx leucoryx) Held in Captivity in the Sultanate of Oman 阿曼苏丹国圈养阿拉伯羚羊 (Oryx leucoryx) 体内沙特艾美球虫 (Eimeria saudiensis) 的形态学与分子特征

Wildlife Letters, EarlyView.
Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

Comparative transcriptomic signatures of virulent and attenuated Mycobacterium bovis growing in vitro and in mice

Frontiers in Cellular and Infection Microbiology
Bovine tuberculosis (bTB), caused by Mycobacterium bovis (M. bovis), poses a significant global health and economic burden. Despite extensive research, a comprehensive understanding of M.

Interleukin 10 knock-down in bovine monocyte-derived macrophages has distinct effects during infection with two divergent strains of Mycobacterium bovis.

PLoS ONE, 2019
Mycobacterium bovis is the causative agent of bovine tuberculosis (TB), a cattle disease of global importance. M. bovis infects bovine macrophages (Mø) and subverts the host cell response to generate a suitable niche for survival and replication.

Vaccination of neonatal calves withMycobacterium bovisBCG induces protection against intranasal challenge with virulentM. bovis [PDF]

Clinical and Experimental Immunology, 2004
SummaryVaccination of neonates with Mycobacterium bovis bacillus Calmette–Guérin (BCG) may be a strategy that overcomes reduced vaccine efficacy associated with exposure to environmental mycobacteria in humans and cattle. Preliminary comparisons indicated that 2-week-old calves produced an immune response to vaccination at least as intense as that ...

DsiRNA‐mediated silencing of Ceratitis capitata transformer or transformer‐2 leads to masculinization of XX embryos and systemic gene silencing in ovaries

Insect Science, EarlyView.
We carried out functional studies using Dicer‐substrate small interfering RNAs (DsiRNAs), targeting the sex determination genes Cctransformer (Cctra) and Cctransformer‐2 (Cctra‐2) in the Mediterranean fruit fly (Ceratitis capitata). Microinjection of DsiRNAs into XX embryos (0‐1 h old) rapidly triggered the expression of male‐specific Cctra isoforms ...

Evolution of cell types and T-cell subsets in the spleens of Mycobacterium bovis BCG-resistant and M. bovis BCG-susceptible strains of mice after infection with M. bovis BCG [PDF]

Infection and Immunity, 1985
In mice, the early host response to intravenous infection with small doses of dispersed Mycobacterium bovis BCG is controlled by the Bcg gene. After infection with a low dose of M. bovis BCG, Lyt-1+ cells were generated in the spleens of BCG-susceptible mice (Bcgs) in parallel with an increase in the proportion of phagocytic cells.

The Paediatric BCG Vaccine Century: From Historical Success to Future Innovations

Acta Paediatrica, EarlyView.
ABSTRACT Aim The tuberculosis (TB) vaccine, Bacille‐Calmette‐Guérin (BCG), protects infants against severe forms of primary TB. Yet, it does not protect against pulmonary reactivation TB in adults. Methods A literature review was conducted between 1st January and 28th February 2025 using PubMed, Google Scholar and reports of the World Health ...
