Resumo: Objetivou-se com este estudo comparar genotipicamente 35 isolados de Corynebacterium pseudotuberculosis recuperados de conteúdo de abscessos de caprinos e ovinos com linfadenite caseosa, procedentes de cinco municípios localizados no Sertão de Pernambuco, Brasil. Utilizou-se a técnica de fingerprint RFLP-PCR com as enzimas de restrição Hpy-Ch4 e Msp1 aplicada ao gene rpoB e as enzimas Pst I e Msp I para o gene pld. Não houve diferença nos padrões de fragmentos de bandas entre os isolados, independente da espécie hospedeira ou da área geográfica estudada, definindo-se um padrão genotípico homogêneo de C. pseudotuberculosis responsável por abscessos superficiais na região.
[Genotypic comparison between Corynebacterium pseudotuberculosis samples obtained from sheep and goats with caseous lymphadenitis, raised in the semi-arid region of Pernambuco].
Abstract: The objective was to genotypically compare 35 samples of Corynebacterium pseudotuberculosis obtained from abscesses of sheep and goats diagnosed with caseous lymphadenitis originated from 5 different municipalities in the semi-arid region of Pernambuco, Brazil. The RFLP-PCR technique with Hpy-Ch4 and Msp I and Pst I Msp I restriction enzimes was used to fingerprint the genes rpoB and pld, respectively. The results demonstrate that there was no difference on the fragments banding pattern among samples, independently of the host species or geographic area studied, defining a homogeneous profile of C. pseudotuberculosis responsible for superficial abscesses for the region.

Iron bands, fragipans and duripans are common in yellow low-activity clay soils developed from the Barreiras Group in coastal plateaus of northeastern Brazil. Such indurated horizons are found in depressions of the plateaus where sugar cane growth is greatly reduced. Little research has being done on the nature of their bonding agents and their genesis. Research carried out in arid zones has frequently attributed duripan consistency to amorphous silica; however, duripans in northeast Brazil occur under higher rainfall (1500-2000 mm). The objective of this work was to study the nature and distribution of soil features in a plateau to better understand the processes associated with soil hardening. Two transects, across a small and a large depression, were investigated using field soil characterisation, micromorphological techniques, and mineralogical and geochemical analyses. The formation of the indurated horizons studied is due to two sequential processes: development of aquic conditions and incipient podzolization. Such processes have affected the upper part of a thin (<0.6 m in small depressions) or thick (>0.6 m in large depressions) compact clay horizon, showing horizontal plans likely inherited from the sediment. Onset of aquatic conditions formed the first fragipans overlying iron bands. Later, aquic conditions are combined with incipient podzolization to produce bleached loose horizons overlying duripans and iron bands. As the bonding agents in the duripans are organo-metallic complexes, these duripans appear to be very different from those described in arid environments.
