The Relationship

ABSTRACTA two-step allele replacement mutagenesis procedure, using a conditionally replicating plasmid, was developed to allow the creation of targeted, marker-free mutations inCorynebacterium pseudotuberculosis. The relationship between homologous sequence length and recombination frequency was determined, and enhanced plasmid excision was observed due to the rolling-circle replication of the mutagenesis vector. Furthermore, an antibiotic enrichment procedure was applied to improve the recovery of mutants. Subsequently, as proof of concept, a marker-free,cp40-deficient mutant ofC. pseudotuberculosiswas constructed.

ABSTRACT: The semiarid northeast of Brazil contains a unique biome known as caatinga, with a maximum temperature of 40 ºC and a relativity humidity of 56%. The caatinga is characterized by a variety of plants, including Cereus jamacaru Dc (mandacaru), Poincianella microphylla Mart. ex G. Don (catingueira), Pilosocereus gounellei FAC Weber (xique-xique) and Mimosa tenuiflora (Willd.) Poir (jurema preta). Sheep and goat industries are economically strong in that region, despite the fact that caseous lymphadenitis is highly prevalent. The aim of the present study was to assess the survival and biofilm production of Corynebacterium pseudotuberculosis isolates in the environment and under controlled temperatures (28°C, 37°C and 42°C) under different surfaces (plants, soil, wood, wire and thorns). In addition, we investigated the effects of applying the disinfectants chlorhexidine, hypochlorite and quaternary ammonia in soil, tiles, wood and vegetation cover. Four strains of C. pseudotuberculosis were selected (two from goats and two from sheep) for inoculation according to their in vitro biofilm production. Adherence to microplates was used to assess the biofilm-forming ability of the bacteria. Lower survival rates were observed when isolates of C. pseudotuberculosis were subjected to a temperature of 42°C. In terms of caatinga biome plants, contamination of jurema-preta plants resulted in the lowest survival rates. The disinfectant quaternary ammonia promoted a lower inoculum survival in all surfaces. The disinfectants and the higher temperature contributed to the reduction of biofilm production in isolates of C. pseudotuberculosis. knowledge of these patterns is important for the establishment of disease control measures, given the questionable efficacy of the treatment and the immuno-prophylaxis of caseous lymphadenitis.

Descreve-se presença de lesão pulmonar em cabra (Capra hircus) sugestiva de criptococose. O cultivo bacteriológico realizado a partir de material purulento articular revelou concomitante infecção por Corynebacterium pseudotuberculosis. À microscopia óptica observaram-se estruturas leveduriformes nos espaços alveolares do pulmão, dotadas de espessa cápsula de polissacarídeos PAS positivas, compatíveis com Cryptococcus spp. Casos de criptococose em caprídeos são considerados raros na literatura. Objetiva-se relatar os aspectos epidemiológicos e clínico-patológicos da forma pulmonar de infecção por Cryptococcus spp. em uma cabra no Brasil.

O presente estudo investigou o uso da cito-(73,0%), Arcanobacterium pyogenes (6,0%), Streptococlogia aspirativa com agulha fina no diagnóstico da lin-cus spp. β hemolítico (5,0%) e Escherichia coli (4,0%) fadenite em ovinos e a ocorrência de microrganismos foram os microrganismos mais frequentes nos animais nos linfonodos com lesões, com ênfase no isolamento de com linfadenite. Streptococcus spp. (21,0%) e Staphylo-Corynebacterium pseudotuberculosis. Foram utilizados coccus spp. (7,0%) foram as bactérias isoladas com 100 linfonodos de ovinos com aumento de volume su-maior frequência nos linfonodos sem lesões colhidos em gestivos de linfadenite e 100 linfonodos de ovinos sem abatedouro. A punção aspirativa com agulha fina perlesões, colhidos em abatedouro. C. pseudotuberculosis mitiu identificar microrganismos "corineformes" em 79 (79,0%) animais com linfadenite e, destes, 73 (73,0%) foram identificados como C. pseudotuberculosis. Nenhuma linhagem de C. pseudotuberculosis foi isolada dos linfonodos dos animais sem lesões. Concluiu-se que C. pseudotuberculosis foi o microrganismo mais freqüente nos ovinos com linfadenite, e que a citologia aspirativa pode ser utilizada como método de triagem no diagnóstico da linfadenite caseosa ovina
