Spices are becoming increasingly important world-wide due to their effectiveness as natural antibiotics, the thing that makes the world nowadays tend to use spices instead of chemical drugs. However, this doesn’t mean they are free of some dangerous pathogens such as Klebsiella spp. which can lead to a wide range of illnesses, notably pneumonia, urinary tract infections (UTIs), and bacteremia. Although we don’t know the natural habitat of this bacterium we find that it thrives in herbs and spices, concluding thus that plants may be its natural habitat. The primary isolation of this bacterium was based first on its growth on general media and then isolation on selective media. Colonies of the microorganisms were counted on different media then Klebsiella was isolated from a selective media. The isolated colonies of Klebsiella were circular, dome-shaped, 3-4 mm in diameter, with mucoid sticky edges, and surrounded by capsule. After this we chose the typical colony and identified it using Polymerase chain reaction PCR and biochemical tests. Our results showed that 32% of examined specimen contained Klebsiella spp.
Leishmaniasis spreads in eighty-eight countries, including the Syrian Arab Republic. This disease is caused by a protozoic parasite of the genus Leishmania. Twenty-two species of leishmania were reported to be pathogenic for human. The disease is presented in three clinical forms: cutaneous, mucocutaneous and visceral leishmaniasis. A set of methods for diagnosis and identifying the type of parasite have been developed in order to give appropriate treatment. These methods include isoenzyme analysis, serological and immunological methods and DNA hybridization. The polymerase chain reaction (PCR), using genomic or kinetoplastid DNA; provides an excellent tool for diagnosis and characterization of leishmania species. In this work, the two types of DNA were extracted in one step from cultured isolates taken from patients. We have used kinetoplastid DNA and specific primers to determine parasite species by PCR. These primers amplify species specific fragment. In this study, we have determined that the causative species of the cutaneous leishmaniasis in all patients was L.tropica.
Enterobacter sakazakii is considered an opportunistic pathogen that has been associated with severe lethal infections especially in neonates, elderly, and Immunocompromised adults. E. sakazakii is a Gram negative, facultative anaerobes rod-shaped bacterium. It belongs to the family Enterobacteriaceae and genus Enterobacter. Although we don’t know the natural habitat of this bacteria we find that it exists in high rate in herbs and spices which indicates that plant may be this natural habitat.
Brucellosis is an endemic zoonosis in Syria, affecting large numbers of animals and an increasing number of humans. Brucella is an intracellular pathogen capable of infecting animals and humans. The aim of this study was to develop a polymerase ch ain reaction (PCR) protocol for the detection of Brucella melitensis in artificially contaminated cheese.
