The bacterium Xenorhabdus nematophila is an insect pathogen and an obligate symbiont of the nematode Steinernema carpocapsae. X. nematophila makes a biofilm that adheres to the head of the model nematode Caenorhabditis elegans, a capability X. nematophila shares with the biofilms made by Yersinia pestis and Yersinia pseudotuberculosis. As in Yersinia spp., the X. nematophila biofilm requires a ...

The geographical distribution of Phlebotomine sandflies of the Lutzomyia intermedia complex is presented, based in collections for this study and in personal informations from other workers and bibliography. The subject is discussed, in relation to climate and to altitude and latitude. Lutzomyia intermedia s.s. was found in smaller altitudes and latitudes than Lutzomyia neivai; the last species...

Equine pituitary pars intermedia dysfunction (PPID) is a well-recognized disease in aged horses and ponies, yet the etiology and pathophysiology of this condition remains poorly understood. Immunohistochemistry of formalin-fixed pituitary tissue was used to demonstrate dopaminergic neurodegeneration and oxidative stress in the pars intermedia in horses with PPID. The role of oxidative stress in...

In this study, we report on a case of refractory, unilateral anaerobic conjunctivitis. The predominant anaerobic flora consisted of Prevotella intermedia (formerly Bacteroides intermedius) and Peptostreptococcus micros. By using the technique of restriction endonuclease fingerprinting of genomic DNA, it was shown that the P. intermedia likely originated from the oral cavity. Topically applied a...

Thalassaemia intermedia includes thalassaemias with clinical severity intermediate between asymptomatic thalassaemia minor and transfusion dependent thalassaemia major. By definition patients of thalassaemia intermedia maintain a haemoglobin level of 7-10 g/dl and do not, or only occasionally, require blood transfusion. An eight-year-old girl who was a known case of thalassaemia intermedia and ...
