To isolate and detect anthrax spores from soil in different regions of Isfahan, Iran a total of 60 environmental specimens were collected during 2003. Bacterial endospores were extracted via flotation in distilled water and were cultured on blood agar and selective PLET media. Bacillus anthracis was identified using bacteriological and biological tests. Viable Bacillus anthracis spores were iso...

The risk of dengue virus infection to travelers visiting dengue fever endemic regions was studied through the use of mathematical modeling. A Susceptible-Infected-Recovered (SIR) model is used to describe the transmission of dengue fever (DF) in an endemic region into which tourists enter. The dynamics of a new class of human, the traveler, is incorporated into the systems of first order differ...

Black leg has been reported in a variety of animals, but is ofthe most importance in cattle and sheep. A20 days old Holsteindairy calf was examined because of anorexia and lameness from2 days ago. The calf was depressed, tachypneic, tachycardic, andhad a body temperature of 38.5ºC. Both hind limbs proximal tothe tarsal joint were markedly swollen, firm and painful. Nocrepitation was noted on pa...

In rabies endemic regions, a proportionally higher incidence of rabies is often reported in dogs younger than 12 months of age, which includes puppies less than 3 months of age; this presents a serious risk to public health. The higher incidence of rabies in young dogs may be the effect of low vaccination coverage in this age class, partly as a result of the perception that immature immune syst...

The efficacy of co-trimoxazole for the treatment of Plasmodium falciparum parasitaemia in children younger than 5 years of age was evaluated in Malawi. 46 children with P falciparum parasitaemia, 37% of whom also met clinical criteria for a diagnosis of acute lower respiratory tract infection, were treated with 20 mg/kg co-trimoxazole twice daily for five days. Parasitaemia (mean clearance time...

The flora of Mexico includes about 119 endemic or nearly endemic genera of Asteraceae. In this study, the genera are listed and their distribution patterns among the floristic provinces of Mexico analyzed. Results indicate strong affinities of the endemic genera for mountainous and arid or semiarid regions. Since its first appearance in Mexico, the Asteraceae diversified into these kinds of hab...

The upper urothelial carcinomas (UUC) associated with endemic nephropathy and analgesic nephropathy are considerably similar in many characteristics. These similarities diversify them from the same carcinomas in the general population w1x. Bilateral occurrence (simultaneous or successive) of the UUC is observed in about 8% cases of analgesic nephropathy and 10–14% in endemic Balkan nephropathy....

Behçet’s syndrome (BS) is a rare, heterogeneous multisystem inflammatory condition, characterized by recurrent orogenital ulcers and uveitis. Vascular involvement affects 10–30% of patients, is most frequently observed in young males and usually presents as superficial or deep venous thrombosis (DVT) [1]. The spectrum of thrombosis also includes vena cava occlusion (inferior or superior), Budd–...

  Hydatid disease is a parasitic infection caused by Echinococcus granulosus (larval form) in humans with lesions most frequently encountered in the liver and lungs. It can rarely involve extra-hepatic organs. It is endemic in some regions of Iran. The omental hydatid cyst is a very rare manifestation of the disease. This report presents the interesting case of a very large omental hydatid cyst.
