In the present review, the history of zoological expeditions that were undertaken on the Jordanian fauna are presented. The published zoological studies reg&ding mammals, birds, reptiles, freshwater fishes, freshwater Mollusca, Siphonaptera and lxodidae are reviewed.Some remarks are made on recent trends in zoological studies carried out by Jordanian zoologists.

Envisaging the role of Co in theranautics and biomedicine it is immensely important to evaluate its antimicrobial activity. Hence in this study CoO thin nanosheets (CoO-TNs) were synthesized using wet chemical solution method at a very low refluxing temperature ($90^{\circ}C$) and short time (60 min). Scanning electron microscopy of the grown structure revealed microflowers ($2{\sim}3{\mu}m$) composed of thin sheets petals (60~80 nm). The thickness of each individual grown sheet varies from 10~20 nm. Antimicrobial activities of CoO-TNs against two Gram positive bacteria (Micrococcus luteus, and Staphylococcus aureus), and two Gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa) were determined. A 98% and 65% growth inhibition of M. luteus and S. aureus respectively, was observed with $500{\mu}g/ml$ of CoO-TNs compared to 39 and 34% growth inhibition of E. coli and P. aeruginosa, respectively with the same concentration of CoO-TNs. Hence, synthesized CoO-TNs exhibited antimicrobial activity against Gram negative bacteria and an invariably higher activity against tested Gram positive bacteria. Therefore, synthesized CoO-TNs are less prone to microbial infections.

We report here a human case probably mixed-infected with Clonorchis sinensis and Fasciola sp. who was diagnosed by computed tomography (Cn scan, serological findings, and/or fecal examination. The patient was a 43-year-old Korean female and was admitted to Kyung Hee University Hospital with the complaints of fever and abdominal pain. On admission, marked eosinophilia was noted in her peripheral blood. CT scan showed specific lesions for clonorchiasis and fascioliasis in the liver, along with lesions suggestive of amebic abscess. Micro-ELISA revealed positive results for the 2 helminthic infections. Eggs of C. sinensis and trophozoites of Entamoeba histo/ytica were observed in the stool. Treatment with praziquantel followed by metronidazole and tinidazole reduced abnormalities in the liver and eosinophilia. This is the first case report of a possible co-infection with 2 kinds of liver flukes in the Republic of Korea.

Sitophilus oryzae L. (Rice Weevil) is a stored pest of rice that causes extensive loss throughout the world. We tested the leaf powders of 12 plant species viz., Chrysanthemum sp., Cinnamomum zeylanicum, Citrus grandis, Citrus limon, Gliricidia sepium, Gymnema sylvestre, Hemigraphis colorata, Michelia champaca, Moringa oleifera, Murraya koenigii, Polyalthia longifolia, and Sauropus androgynus at dosages of 1.00, 1.50, 2.00 and 3.00g against the adult rice weevil and mortality was recorded at 1, 2, 3, 5, 7, 12 and 2l days after treatment (DAT) by direct contact toxicity for their adulticidal effect. We observed 100 percent adult mortality in C. zevlanicum and M. koenigii among the tested leaf powders. In addition, the first-time tested H. colorata and S. androgynus also caused high mortality compared to other plants. All the plant powders caused moderate to high adult mortality. Hence, these plants could be effective botanical insecticides against S. oryzae as they comprise a potential source of bioactive chemicals and are generally free from toxicants. Applications of these natural derivatives in S. oryzae control could reduce the cost of control methods and storage of rice contamination. Therefore, the present study indicates that some plant extracts can be used as an alternative to toxic synthetic chemicals in the management of rice weevils.

Leucosia anatum, also known as the pebble crab, is a species of crab that belongs to the family Leucosiidae. Crabs are the most conspicuous and abundant components of the epibenthic macrofauna of the mangrove ecosystems. The present investigation was carried out with the objective of enlightening the reproductive system of L.anatum through histological and histochemical studies. Histological analysis of the epithelial cells of vas deferens, the luminal size and shape of the vas deferens was carried out, since the spermatophore material is secreted and molded by the vas deferens. Histochemical analysis of the blood plasma, testis, proximal vas deferens, middle vas deferens, distal vas deferens, seminal plasma and spermatophore was done to reveal the possible transformation of their secretory materials into the spermatophoric components. Biochemical components present in the blood plasma, testis, proximal vas deferens (PVD), median vas deferens (MVD) and distal vas deferens (DVD) regions seminal plasma and spermatophore of pebble crab were analyzed to find out the quantity of free sugars, proteins, and fats. Thus the current study focuses on the histological and histochemical analysis of Testis and Vas Deferens and their secretions in L.anatum.
