Abstract
Clinical identification of the pathogenic bacterium Moraxella catarrhalis in cultures relies on the detection of bacterial butyrate esterase (C4-esterase) using a coumarin-based fluorogenic substrate, 4-methylumbelliferyl butyrate. However, this classical probe may give false-positive responses because of its poor stability and lack of specificity. Here, we report a new colorimetric and fluorogenic probe design employing a meso-ester-substituted boron dipyrromethene (BODIPY) dye for the specific detection of C4-esterase activity expressed by M. catarrhalis. This new probe has resistance to nonspecific hydrolysis that is far superior to the classical probe and also selectively responds to esterase with rapid colorimetric and fluorescence signal changes and large "turn-on" ratios. The probe was successfully applied to the specific detection of M. catarrhalis with high sensitivity.

Abstract
Sixteen strains belonging to three families of the Rhizobiales order (Bradyrhizobiaceae, Phyllobacteriaceae and Rhizobiaceae) were evaluated according their specific growth rates (micro) and the activity of intracellular alpha-esterase and beta-esterase isoenzymes. The average esterase activity of 48 isoenzymes assayed belonging to five strains with low (micro(max) = 0.08-0.12 h(-1)), four medium (micro(max) = 0.13-0.22 h(-1)) and seven high (micro(max) = 0.24-0.28 h(-1)) growth rate values were 22.1 +/- 4.3; 8.7 +/- 2.2 and 3.9 +/-1.7 U g(-1) respectively. An inversely proportional relationship between the activity of the whole pattern of esterases and micro(max) was found. Our results illustrate a feature of intracellular esterases, ascribable in a variety of cellular functions, which might be related to characteristics micro(max) of legume infecting bacteria.

Abstract
AIMS To evaluate the esterase phenotype in Lactococcus lactis strains isolated from traditional Tunisian dairy products. METHODS AND RESULTS A collection of 55 L. lactis strains isolated from traditional fermented milk products and three reference strains were identified at species and subspecies level using molecular methods targeted to the 16S rRNA gene and to the histidine operon. The genotypic data obtained allowed the identification of the strains as L. lactis ssp. lactis and L. lactis ssp. cremoris with the prevalence of the ssp. lactis. The phenotypic identification based on arginine hydrolysis, the growth at 40 degrees C and in presence of 4% NaCl showed several discrepancy with the identification data based on genotypic analysis. Additional experiments carried out evaluating the esterase electrophoretic patterns revealed four classes of esterases identified on the basis of their electrophoretic mobility and specific activity on alpha- and beta-naphthyl ester of acetate and propionate. Esterase profiles discriminated the strains in two main groups corresponding to the subspecies cremoris and lactis according to a DNA-based identification. CONCLUSIONS The evaluation of esterase activity represents a novel phenotype for the taxonomic discrimination of the L. lactis ssp. lactis and cremoris. SIGNIFICANCE AND IMPACT OF THE STUDY Besides the DNA-based techniques that allow the rapid and accurate species/subspecies identification, the electrophoretic esterase profiles of L. lactis strains represents: (i) a new phenotypic tool to understand the physiology and the ecology of this species; and (ii) a new test for the potential selection of flavour producing strains.

Abstract
Listeria monocytogenes is a major concern to producers of ready-to-eat foods because of the high mortality rate associated with listeriosis and the widespread nature of the organism. To investigate the prevalence of this pathogen in different ready-to-eat food products on the Belgian market, a variety of 252 ready-to-eat food products, mainly fish and meat products, were analyzed. Overall, L. monocytogenes was detected in 23.4% of the samples. The highest prevalence of L. monocytogenes was found in prepared minced meat (42.1%) and smoked halibut (33.3%). Contamination levels were in most cases low (<10 CFU/g); however, levels higher than 100 CFU/g were detected in some samples of smoked salmon, smoked halibut, and prepared minced meat. A high prevalence of Listeria innocua (15.8%) and Listeria welshimeri (36.8%) was detected in prepared minced meat. L. monocytogenes strains isolated from different contaminated products were subjected to repetitive element sequence-based PCR (REP-PCR) typing to determine possible associations with product type, producer, or market. REP-PCR patterns were analyzed using BioNumerics software, and seven different groups with at least 90% similarity were identified. The cluster analysis indicates that cross-contamination occurred at the producer and retail level. Serotype identification of the strains by PCR revealed that most belonged to the 1/2a(3a) serotype group.

Abstract
41 clinical Listeria monocytogenes strains recovered from seven feto-maternal and 34 non-pregnancy associated cases of human listeriosis documented between 1997 and 2000 underwent serotyping and typing by pulsed-field gel electrophoresis (PFGE) applying the enzymes AscI, ApaI and SmaI. The pulsotypes of the clinical strains were compared to the pulsotypes of three L. monocytogenes strains isolated from healthy fecal carriers and nine reference strains isolated from seven outbreaks in Europe and the USA. The 41 clinical strains of Austrian provenance showed 37 pulsotypes. Five sets of two Austrian strains each were indistinguishable by PFGE typing. Epidemiological links were absent between these indistinguishable isolates. One unique pulsotype (AB) was found in three fecal isolates. Five pulsotypes (A, Q, R, AC and AD) were distinguished among the strains associated with outbreaks. Clusters consisting of two, five and six Austrian strains each were indistinguishable from the outbreak-associated pulsotypes A, Q and R, respectively, after PFGE analysis with AscI. Three strains of AscI pulsotype Q and five strains of AscI pulsotype R could be further differentiated by restriction with ApaI and SmaI. One strain each from sporadic cases shared a combined pulsotype with the outbreak strains of pulsotypes A and R, respectively. These PFGE data suggest that a similar genetic background can be found in strains which have been contributing to outbreaks world-wide and in isolates associated with sporadic listeriosis in Austria.

Abstract
Populations of Listeria monocytogenes strains isolated in Belgium from cheese and from patients with listeriosis were characterised by randomly amplified polymorphic DNA (RAPD) analysis using two 10-mers primers (OPA-04 and OPA-13). High discrimination levels were obtained with each of these primers alone (discrimination indices (DI) of 0.899 and 0.935 for OPA13 and OPA04, respectively) or in combination (DI of 0.960). The clustering of strains obtained by RAPD was compared with a clustering previously made using serotyping and esterase typing. RAPD allowed the subdivision of each serovar cluster and of most of the clusters determined by the polymorphism of the bacterial esterases. Our analysis indicates that the population of strains of L. monocytogenes found in cheese differs from the one isolated from patients with listeriosis during the same period.

Abstract
Human lice (Phthiraptera: Pediculidae) from Africa, America and Europe were electrophoresed for 28 enzymes, with special interest in metabolic factors likely to be involved with insecticide resistance. Zymogram profiles of the body louse (Pediculus humanus L. from France and U.S.A.) and the head louse (P. capitis DeGeer from France, Madagascar, Mali & Senegal) were compared. Only esterase two enzymes, phosphoglucomutase (Pgm) and 3 (Est-3), showed electrophoretic variation. In our starch gel electrophoresis conditions, P. humanus showed three electromorphs of Pgm migrating anodally 6, 11 and 16 mm (designated alleles a, b, c, respectively). Of the putative Pgm alleles, b and c occurred in all samples of both species of lice, whereas allele a was found only in P. humanus lab strain from U.S.A. Esterase 3 had four electromorphs migrating 23, 26, 30 and 35 mm (designated alleles a, b, c and d). Among putative Est alleles, a was found only in P. capitis from Bamako (all 14 specimens aa homozygotes), allele d was found only in P. capitis from Dakar (39% frequency), whereas Est-3 alleles b and c showed apparently balanced polymorphism in all samples of both P. humanus and P. capitis except that from Bamako. Despite the limited amount of isoenzyme variation detected (only 2/31 polymorphic loci), divergences of Est-3 and Pgm among Pediculus populations may be relevant to their biosystematics and resistance.

Abstract
Listeria monocytogenes strains possess short repetitive extragenic palindromic (REP) elements and enterobacterial repetitive intergenic consensus (ERIC) sequences. We used repetitive element sequence-based PCR (rep-PCR) to evaluate the potential of REP and ERIC elements for typing L. monocytogenes strains isolated from humans, animals, and foods. On the basis of rep-PCR fingerprints, L. monocytogenes strains were divided into four major clusters matching origin of isolation. rep-PCR fingerprints of human and animal isolates were different from those of food isolates. Computer evaluation of rep-PCR fingerprints allowed discrimination among the tested serotypes 1/2a, 1/2b, 1/2c, 3b, and 4b within each major cluster. The index of discrimination calculated for 52 epidemiologically unrelated isolates of L. monocytogenes was 0.98 for REP- and ERIC-PCR. Our results suggest that rep-PCR can provide an alternative method for L. monocytogenes typing.

Abstract
Five typing methods were compared in a study designed to adapt a strategy for epidemiologically typing large numbers of Listeria monocytogenes strains. The methods studied were serotyping, electrophoretic typing of esterases (zymotyping), restriction fragment length polymorphism of ribosomal DNA (ribotyping), random amplified polymorphic DNA (RAPD) and pulsed-field gel electrophoresis (PFGE). Data were analysed by computer-assisted statistical analysis. Included in the analysis were 35 strains of L. monocytogenes, including 14 epidemic strains isolated during outbreaks in France in 1992 and 1993, and 21 strains isolated from food and the environment. Five serotypes, eight zymotypes, ten ribotypes, 13 RAPD patterns and 12 PFGE patterns were identified among the 35 strains. The most discriminating combination of typing methods was ribotyping and PFGE typing [27 types, discriminatory index (D.I.) = 0.978]. A factorial analysis of correspondence for each method differentiated the epidemic strains from the environmental strains. This study shows that computer-assisted statistical treatment of the data, combined with the use of discriminating typing methods, is a powerful tool for the epidemiological analysis of Listeria monocytogenes.

Abstract
Listeria monocytogenes is an intracellular gram-positive organism responsible for severe infections in both humans and animals. Whereas the food-borne transmission of listeriosis was demonstrated in several outbreaks, most cases of listeriosis occur sporadically and are rarely linked with consumption of contaminated foods. In this paper a case of septicaemia with L. monocytogenes in a 73-year-old immunocompromised man is described. Evidence for the association of this case of listeriosis with the consumption of a contaminated 'Camembert' cheese is provided by serotyping, esterase typing, DNA macrorestriction patterns analysis and level of virulence of the isolated strains for mice.

Abstract
Multiple bands of alpha-naphthyl-propionyl esterase (alpha NPE) activity observed following starch gel electrophoresis of cell extracts allowed 219 Listeria monocytogenes isolates from milk, nondairy foods, and clinical and veterinary sources to be assigned to 17 different alpha NPE types. Multilocus enzyme electrophoresis (MEE) analysis was used to obtain electrophoretic mobility data for alpha NPEs and nine other metabolic enzymes; on the basis of these data, the 219 strains were assigned to 59 electrophoretic types. Each of the methods separated the strains into two main groups, and there was extensive agreement on assignment of the strains to the groups. Although the method is less discriminatory than MEE, the usefulness of alpha NPE electrophoresis alone as a rapid, simple typing method for L. monocytogenes for certain purposes is indicated by agreement among alpha NPE, MEE, and restriction fragment length polymorphism types as molecular markers for persistent and transient L. monocytogenes strains found in sequential raw-milk and nondairy food samples obtained from different processors.

Abstract
Listeria monocytogenes strains isolated in Belgium from different foodstuffs and in sporadic cases of human listeriosis were analyzed. The distribution of serovars differed in each of these populations. The bacteria isolated from cheeses and from human patients with listeriosis were further studied by esterase typing. The twenty esterase patterns defined were not equally distributed in these two populations. The secretion of the virulence determinant phosphatidylinositol-specific phospholipase C and the pathogenicity level of strains in immunocompromised mice could not explain the unequal distribution of esterase types. The discrimination index of esterase typing (DI = 0.868) was compared with that of serotyping (DI = 0.666) and with that of the two combined methods (DI = 0.899).
