Background & Aim: Information literacy is a concept emerged through the rapid transformation of information technologies, which is essential to survival in an information community. The present study aimed to determine information literacy and its contributing factors in the students of

Cutaneous leishmaniasis is one of the most important public health problem in many developing countries. The present study was conducted to determine the vector(s), the parasite and the species composition of sand flies in the Dehloran County during May-November 2012. Sand flies were collected by sticky traps and mounted in Puri's medium for species identification. Polymerase chain reaction (PCR) techniques of kDNA, ITS1-rDNA, followed by restriction fragment length polymorphism (RFLP) were used for identification of DNA of Leishmania parasites in infected sand flies. A total of 82443 specimens comprising 15 species of sand flies (5 Phlebotomus and 10 Sergentomyia) were collected and identified. The species of Phlebotomus papatasi was dominant in outdoor and indoor resting places. Among the 280 specimens of female P. papatasi tested by PCR of kDNA, ITS1-rDNA genes of the parasite followed by RFLP, only 5 of them (1.8 %) were positive to Leishmania major parasites. This is the first molecular detection of leishmania infection of P. papatasi to L. major in this region. The results indicated that, P. papatasi was only species found infected by L. major and the principal vector of disease agent to human.

Introduction:American cockroaches, Periplaneta americana, are the most important pests in hospitals and dwelling environments. They are mechanical vectors of some bacterial pathogens.Goal:The present investigation was carried out in Ghods hospital and 5 dwelling localities of Paveh city to evaluate bacterial infestations of American cockroaches in this region of Iran.Methods:The samples were randomly collected from hospital environments and toilets and kitchens of the dwelling localities from December-March 2012 and July-September 2013. The samples were captured using sterile test tubes and sterile hand gloves.Results:Totally, 98 cockroaches were collected from hospital (45.9%) and dwelling (54.1%) environments. Eight groups of bacteria including: Pseudomonas spp., Proteus spp., Klebsiella spp., Staphylococcus spp., Bacillus spp., Serratia spp., Entrobacter spp. and Escherichia coli were extracted.Conclusions:The findings of the present study revealed that the American cockroaches are very important in transmission of some bacterial pathogens, so health education and using the effective control methods to elimination and reduction of cockroaches are necessary.

This descriptive study was carried out to determine bacterial infection rate of cockroaches in the residential dwellings. A total of 650 cockroaches were collected in Sanandaj city houses using sticky traps, direct collection and vacuum cleaner. After determination, 85 of them were examined in base standard methods for bacterial infection. Two species of cockroaches including Blattela germanica (54%) and Periplaneta americana (46%) were collected. 74% of cockroaches had bacterial infection and separated into seven groups including: Pseudomonas, Enterobacter, Escherichia, non pathogens staphylococci, Klebsiella, Proteus and Seratia. Escherichia coli had the most frequency (61.5%) and Seratia (6.1%) had the least.
