Genomic Islands of Pseudomonas syringae pv. tabaci 6605: Identification of PtaGI‐1 as a Pathogenicity Island With Effector Genes and a Tabtoxin Cluster

Molecular Plant Pathology, Volume 26, Issue 5, May 2025.
Pseudomonas syringae pv. tabaci genomic island PtaGI‐1 has effector and tabtoxin genes and is necessary for virulence. It is a dynamic element that is excised from the chromosome and circularised. ABSTRACT Genomic islands (GIs) are 20–500 kb DNA regions that are thought to be acquired by horizontal gene transfer.

Examining marginal sequence similarities between bacterial type III secretion system and Trypanosoma cruzi surface proteins: Horizontal gene transfer or convergent evolution? [PDF]

arXiv, 2012
The cell invasion mechanism of Trypanosoma cruzi has similarities with some intracellular bacterial taxa especially regarding calcium mobilization. This mechanism is not observed in other trypanosomatids, suggesting that the molecules involved in this type of cell invasion were a product of (1) acquired by horizontal gene transfer; (2) secondary loss ...

Advances in Fecal Microbiota Transplantation for Gut Dysbiosis‐Related Diseases

Advanced Science, Volume 12, Issue 13, April 3, 2025.
This article reviews the use of fecal microbiota transplantation (FMT) to treat intestinal diseases like recurrent Clostridioides difficile infection (rCDI), inflammatory bowel disease (IBD), and irritable bowel syndrome (IBS). It discusses FMT's efficacy, influencing factors such as donor selection, recipient characteristics, and treatment protocols ...

Salmonella chemoreceptors McpB and McpC mediate a repellent response to L-cystine: a potential mechanism to avoid oxidative conditions [PDF]

Lazova, M. D., Butler, M. T., Shimizu, T. S., and Harshey, R. M., Salmonella chemoreceptors McpB and McpC mediate a repellent response to L-cystine: a potential mechanism to avoid oxidative conditions. Mol Microbiol 84 (4), 697 (2012), 2013
Chemoreceptors McpB and McpC in Salmonella enterica have been reported to promote chemotaxis in LB motility-plate assays. Of the chemicals tested as potential effectors of these receptors, the only response was towards L-cysteine and its oxidized form, L-cystine.

Increased risk for malaria in chronically malnourished children under 5 years of age in rural Gambia.

, 2002
Malaria and malnutrition cause high morbidity and mortality in rural sub-Saharan Africa. To explore the relationship between nutritional status and malaria, a cohort of Gambian children under 5 years of age was followed weekly during one malaria season ...

Cryptosporidium Priming Is More Effective than Vaccine for Protection against Cryptosporidiosis in a Murine Protein Malnutrition Model [PDF]

, 2016
Cryptosporidium is a major cause of severe diarrhea, especially in malnourished children. Using a murine model of C. parvum oocyst challenge that recapitulates clinical features of severe cryptosporidiosis during malnutrition, we interrogated the effect ...

A rapid molecular approach to determining the occurrence of pathogen indicators in compost [PDF]

arXiv, 2014
An accurate method for enumerating pathogen indicators, such as Escherichia coli (E. coli), and Salmonella spp. is important for assessing the safety of compost samples. This study aimed to determine the occurrence of pathogen indicators in compost samples by using a molecular approach known as Polymerase Chain Reaction (PCR).
