Comparative analysis of the five major Erwinia chrysanthemi pectate lyases: enzyme characteristics and potential inhibitors
In Erwinia chrysanthemi 3937, pectate lyase activity mainly results from the cumulative action of five major isoenzymes, PelA to PelE, and it is demonstrated that two compounds present in plant tissues, epicatechin and salicylic acid, inhibit the pECTate lyases. Expand
Yersinia enterocolitica type III secretion–translocationsystem: channel formation by secreted Yops
Electrophysiological experiments revealed the presence of channels with a 105 pS conductance and no ionic selectivity that could be responsible for the translocation of Yop effectors, which were generated by mutants devoid of the effectors and by lcrG mutants, as well as by wild‐type bacteria.

Antimicrobial susceptibility of Streptococcus species isolated from clinical mastitis in dairy cows.
The antimicrobial susceptibility was determined for 50 Streptococcus uberis, 42 S. dysgalactiae and S. agalactiae strains isolated from cow mastitis, finding resistance to tetracycline was most frequent, then macrolide and/or lincomycin resistance, and all strains were susceptible to chloramphenicol and rifampicin.

Predicting the Minimal Translation Apparatus: Lessons from the Reductive Evolution of Mollicutes
This analysis showed that slightly different solutions for preserving a functional, albeit minimal, protein synthetizing machinery have emerged in these successive rounds of reductive evolution in Mollicutes, and has broad implications in guiding the reconstruction of a minimal cell by synthetic biology approaches.

Loss of diversity within Mycoplasma bovis isolates collected in France from bovines with respiratory diseases over the last 35 years.
The genotypic diversity between sixty isolates collected in France over the last 35 years was assessed using two molecular subtyping methods that addressed either the long-term epidemiological relationships (Multi Locus Sequence Typing, MLST) or the genetic microvariations (Multiple Locus VNTR Analysis, MLVA).

Identification and Subtyping of Clinically Relevant Human and Ruminant Mycoplasmas by Use of Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry
ABSTRACT Matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS) recently emerged as a technology for the identification of bacteria. In this study, we aimed toExpand
Thylakoid membrane stability to heat stress studied by flash spectroscopic measurements of the electrochromic shift in intact potato leaves: influence of the xanthophyll content
The data presented suggest that de-epoxidized xanthophylls in vivo stabilizeThylakoid membranes and protect thylakoids against heat-induced disorganization. Expand
Temperature-dependent adjustment of the thermal stability of photosystem II in vivo: possible involvement of xanthophyll-cycle pigments
Moderately elevated temperatures induce a rapid increase in the heat and light resistance of photosystem II (PSII) in higher-plant leaves. This phenomenon was studied in intact potato leaves exposedExpand
Mycoplasmoses of ruminants in France: recent data from the national surveillance network
Although VIGIMYC is a passive network and somewhat biased as regards sample collection and processing, it has provided an overview of the main mycoplasmoses of ruminants in France and the French epidemiological situation is compared to those existing elsewhere in the world. Expand
Detection and characterization of tet(M) in tetracycline-resistant Listeria strains from human and food-processing origins in Belgium and France.
In the present study, three Listeria monocytogenes strains and one Listeria innocua strain out of a collection of 241 Listeria isolates from human and food-processing sources were found to displayExpand
