Why genes evolve faster on secondary chromosomes in bacteria [PDF]

open access: yes, 2010
In bacterial genomes composed of more than one chromosome, one replicon is typically larger, harbors more essential genes than the others, and is considered primary.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

Microbial diversity in Baltic Sea sediments [PDF]

open access: yes, 2007
This thesis focuses on microbial community structures and their functions in Baltic Sea sediments. First we investigated the distribution of archaea and bacteria in Baltic Sea sediments along a eutrophication gradient.

Comparative genomics of Shiga toxin encoding bacteriophages [PDF]

open access: yes, 2012
Background Stx bacteriophages are responsible for driving the dissemination of Stx toxin genes (stx) across their bacterial host range. Lysogens carrying Stx phages can cause severe, lifethreatening disease and Stx toxin is an integral virulence factor.

Broad-spectrum resistance to bacterial blight in rice using genome editing

open access: yesNature Biotechnology, 2019
Bacterial blight of rice is an important disease in Asia and Africa. The pathogen, Xanthomonas oryzae pv. oryzae (Xoo), secretes one or more of six known transcription-activator-like effectors (TALes) that bind specific promoter sequences and induce, at ...

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

Bacteria under SOS evolve anticancer phenotypes

open access: yesInfectious Agents and Cancer, 2010
Background The anticancer drugs, such as DNA replication inhibitors, stimulate bacterial adhesion and induce the bacterial SOS response. As a variety of bacterial mutants can be generated during SOS, novel phenotypes are likely to be selected under the ...

Analysis of differentially expressed genes in bacterial and fungal keratitis

open access: yesIndian Journal of Ophthalmology, 2020
Purpose: This study was aimed at identifying differentially expressed genes (DEGs) in bacterial and fungal keratitis. The candidate genes can be selected and quantified to distinguish between causative agents of infectious keratitis to improve ...

Recovery of the Structure and Function of the Pig Manure Bacterial Community after Enrofloxacin Exposure

open access: yesMicrobiology Spectrum, 2022
At present, growth-promoting antibiotics are banned in the pig industry in many countries, but therapeutic antibiotics can still be used normally. However, the effect of therapeutic antibiotics on the structure and function of the intestinal bacterial ...

Nasal Bacterial Microbiome: Probing a Healthy Porcine Family [PDF]

open access: yes, 2011
Upper respiratory tract (URT) infection caused the leading and devastating diseases in pigs. It was believed that the normal microbiome of URT plays a vital role in health and disease development.
