CHITOSAN INHIBITION TEST AGAINST E. coli AND DIGESTIBILITY OF THE RATION IN THE IN-VITRO METHOD

open access: yesJurnal Pendidikan Matematika dan IPA, 2020
Diarrhea and vomiting are often caused by E coli bacteria. E coli bacteria has a strain of Shigatoxigenic Escherichia coli (STEC), producing Shiga poisons or poisons such as Shiga (verotoxin) which are harmful and pollute nature.

Enterohemorrhagic Escherichia coli with particular attention to the German outbreak strain O104:H4 [PDF]

open access: yes, 2012
This review deals with the epidemiology and ecology of enterohemorrhagic Escherichia coli (EHEC), a subset of the verocytotoxigenic Escherichia coli (VTEC), and subsequently discusses its public health concern.

Draft Genome Sequence of an Escherichia coli O157:H43 Strain Isolated from Cattle [PDF]

open access: yes, 2013
Here we report the draft genome sequence of an Escherichia coli O157:H43 strain, designated T22, with an atypical virulence gene profile and isolated from healthy cattle.

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

open access: yesThe FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

New high-affinity monoclonal antibodies against Shiga toxin 1 facilitate the detection of hybrid Stx1/Stx2 in vivo. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Shiga toxin-producing E. coli (STEC) are a group of common and potentially deadly intestinal pathogens expressing Shiga toxin (Stx) as a primary virulence factor.

Whole-genome sequencing for national surveillance of Shiga toxin–producing Escherichia coli O157 [PDF]

open access: yes, 2015
Background. National surveillance of gastrointestinal pathogens, such as Shiga toxin–producing Escherichia coli O157 (STEC O157), is key to rapidly identifying linked cases in the distributed food network to facilitate public health interventions.

Sequence of Shiga Toxin 2 Phage 933W fromEscherichia coliO157:H7: Shiga Toxin as a Phage Late-Gene Product [PDF]

open access: yesJournal of Bacteriology, 1999
ABSTRACTLysogenic bacteriophages are major vehicles for the transfer of genetic information between bacteria, including pathogenicity and/or virulence determinants. In the enteric pathogenEscherichia coliO157:H7, which causes hemorrhagic colitis and hemolytic-uremic syndrome, Shiga toxins 1 and 2 (Stx1 and Stx2) are phage encoded.

Degradomics for large‐scale mechanistic insights on proteases and proteolysis in human health

open access: yesThe FEBS Journal, EarlyView.
Proteolysis has an important role in human disease but remains relatively unexplored. Degradomics, the uncovering of proteolysis in tissues, cells, and proteins, uses mass spectrometry‐based terminomics to identify protein termini occurring therein (forward degradomics) and to define the actions of proteases (reverse degradomics).

Occurrence of Escherichia coli carrying Shiga toxin-producing genes in buffaloes on smallholdings in Bangladesh [PDF]

open access: yesVeterinary World, 2018
Background and Aim: Shiga toxin-producing Escherichia coli (STEC) has emerged as significant foodborne pathogens. Ruminants are the primary reservoir of the zoonotic STEC. In Bangladesh, previous studies reported the presence of STEC in cattle, goat, and

Ricin trafficking in plant and mammalian cells [PDF]

open access: yes, 2011
Ricin is a heterodimeric plant protein that is potently toxic to mammalian and many other eukaryotic cells. It is synthesized and stored in the endosperm cells of maturing Ricinus communis seeds (castor beans).
