A young man is reported with recurrent Staphylococcus aureus joint sepsis associated with dermatomyositis. His dermatomyositis failed to resolve on treatment with antimicrobial agents alone, indicating that if staphylococcal infection was the triggering event for the dermatomyositis then the subsequent process was apparently self perpetuating, requiring cytotoxic agents for its control. This ca...

THE CONCEPT of intestinal antisepsis is not new. I t was under taken without success in the preceding century. Not unti l 1941,20 with the discovery of succinylsulfathiazole, was a practical intestinal antiseptic available. T h e sulfa drugs are bacteriostatic-not bactericidal--agents. Consequently, they must be administered for a considerable period of t ime and the resident organisms must be ...

Olive (Olea europaea) is a crop of great agronomic, economic and cultural interest for the Mediterranean Basin, although increase in world demand olive oil expanding its cultivation by other countries southern hemisphere. The main pathogens include bacteria (Pseudomonas savastanoi pv. savastanoi, Xylella fastidiosa), fungi (Colletotrichum spp., Verticillium dahliae, Fusarium spp. Rhizoctonia so...

In vitro tests were carried out to assess the activity of 26 Brazilian isolates of predatory fungi of the genus Arthrobotrys on a free-living nematode (Panagrellus sp.) and on infective larvae of Haemonchus placei, a parasitic gastrointestinal nematode of cattle. The results showed that the free-living nematode Panagrellus sp. was the most preyed upon, compared to H. placei, for all the fungal ...

Endocarditis due to fungal etiology is rare, but it is the most severe form of infective endocarditis. Fungal endocarditis is commonly complicated by systemic embolizations, and the difficulty in isolating the fungi with routine blood cultures complicates the diagnostic process. In these culture-negative cases of endocarditis, etiologic diagnosis is made with histopathologic examination of the ...

Application of chemotherapy in cancerous children leads to reduction of immune system efficiency. Therefore, these children are prone to various infectious diseases. The excessive use of antibiotics can bring about antibiotic resistant strains. Hence, it is essential to investigate new therapies for this problem. On the other hand, the emergence of resistance against multiple drugs is a major p...

Antifungal susceptibility tests are performed on fungi that cause disease, especially if they belong to a species exhibiting resistance to commonly used antifungal agents. Antifungal susceptibility testing is also important for resistance surveillance, for epidemiological studies and for comparing the in-vitro activity of new and existing agents. Dilution methods are used to establish the MICs ...

There are two main groups of biological agents regarded as occupational hazards: allergenic and/or toxic agents forming bioaerosols, and agents causing zoonoses and other infectious diseases. Bioaerosols occurring in the agricultural work environments comprise: bacteria, fungi, high molecular polymers produced by bacteria (endotoxin) or by fungi (β-glucans), low molecular secondary metabolites ...

Introduction: Environmental fungi, molds and yeasts, can infest the nasal cavity through inhaled air. There is some evidence that they could be the main cause of Chronic Rhinosinusitis (CRS) but little is known about the normal fungal flora in the human nose. The objective of this study was to assess the normal fungal flora of the nasal mucus in adults in Kerman. Materials and Methods: We ...
