A collection of 307 pneumococcal isolates form 84 children and 223 adults admitted to Siriraj Hospital were separated into two groups, penicillin-susceptible (PSSP) and penicillin-nonsusceptible (PNSP). Each group was tested for susceptibilities to 12 drugs (cefuroxime, amoxicillin, chloramphenicol, tetracycline, cefotaxime, ceftriaxone, imipenem, meropenem, ciprofloxacin, ofloxacin, erythromyc...

Phytophthora parasitica, being able to attack a wide variety of plants, is a very important plant pathogen in Taiwan. It has been shown that isolates of P. parasitica from tobacco, dieffenbachia, and loquat differed significantly from other isolates in morphology and pathogenicity and were recognized as “atypical” types of the fungus. In the current study, a partial sequence of the reverse tran...

The genus of Salmonella is very polymorphic and comprised of a number of genetically closely related serotypes. It is one of the emerging pathogen in food-borne disease which is often found in contaminated chicken eggs. Salmonella enterica is considered one of the major pathogens in public health worldwide. A total of 31 Salmonella isolates identified by specific antisera, which included Salmon...

both zoonotic and anthroponotic cutaneous leishmaniasis (cl) caused by l. major and l. tropica, respectively, are endemic in different parts of iran. this study was performed to investigate the new changes in epidemiological pattern of cl, and to identify the species of leishmania and the strains of l. major isolated from different endemic areas of iran. seventy-two isolates from 245 samples co...

Detection of Mycoplasma synoviae (MS) by culture and polymerase chain reaction (PCR) has been reported from commercial chicken farms in different provinces of Iran. In some reports the phylogenetic analysis of MS isolates based on 16S rRNA and variable lipoprotein hemagglutinin (vlhA) genes have been carried out. The PCR product containing partial 16S rRNA genes of Iranain isolates was sequence...
