Lernaea cyprinacea and occurrence of Lernaeasis in farmed and wild warm water fishes is a major problem of aquaculture industry in Iran. The present study was conducted to compare the rate of L. cyprinacea infection between two separate populations of common carp, i.e., fish cultured in ponds and sampled from rice fields. To this end, fish sampling was done during 3 months in summer. After fish sampling, fish were transferred to lab for parasite study. Parasite incidence percent and density were calculated for two population carps. According to obtained results, the parasite incidence percent and density were significantly higher in fish samples taken from fish ponds than in those from rice fields (P < 0.05). In fact, fish from rice fields were more healthy compared to fish from monoculture ponds. In conclusion, our results show that the polyculture of carp with rice can control Lernaea infection. These results may be in relation to the controlling effects of used pesticides in particular diazinon in rice field on this parasite. © 2015, Springer-Verlag London.

Background: Zoonotic Cutaneous Leishmaniasis (ZCL) is a polymorphic disease. It is generally accepted that bacterial superinfection may play a role in the clinical appearance of the lesions and may delay or prevent the healing process. However, the pattern of bacterial pathogens involved has rarely been investigated. Material/Methods: The aim of this study was to identify the bacterial species contaminating the suspected ZCL and their susceptibility to commonly used antibiotics. Microscopic examination of stained smears and cultures were used to differentiate ZCL from non-ZCL lesions in a rural area north of Isfahan, Iran from July to December 2009. Bacteria were isolated from the lesions and identified and antibiotic susceptibility was determined by standard microbiological techniques. Results: The results show that 602 (68%) of 855 patients were positive for ZCL, of which 83.4% with volcano- shape, 8.8% psoriasiform, 6.6% popular form and 1.2% with other atypical forms of ZCL. The bacteria were isolated from 66.8% of ZCL (70% of volcano-shape, 60% of psoriasiform and 25% of popular form) and 64.7% of non-ZCL lesions. The most common species were Staphylococcus aureus (41.7%) and S. epidermidis (28%) followed by Bacillus sp. Streptococcus pyogenes, Escherichia coli, Klebsiella sp., Proteus sp., Enterobacter sp. and Pseudomonas aeroginosa. Ciprofloxacin, Erythromycin, Cefazolin and Clindamycin were the most effective antibiotics. Conclusions: Bacterial superinfection appears to be very common in ZCL, but its prevalence is not different from that of non-ZCL lesions and it has little effect on the clinical appearance of anthroponotic cutaneous Leishmaniasis (ACL). Local lesion care and management of bacterial superinfection must be considered in the treatment of ZCL.

Background & objectives: Leishmaniasis has an annual incidence of 0.5-1.5 million new cases and is endemic in 88 countries throughout the world. About 90% of cases of cutaneous leishmaniasis (CL) are reported from seven countries including Iran. Evidence suggests the increased annual incidence of this disease in Iran. Intracellular protozoan parasite, Leishmania, is an obligatory parasite. Sandflies transfer infectious forms of the parasite or its metacyclic promastigotes to its vertebrate hosts such as humans by biting. In order to review the epidemiology of CL in Isfahan, Iran, factors such as incidence, disease causes, geographic features, age, and sex distribution, nationality, and occupation of patients, and the clinical spectrum of disease were evaluated. Methods: During the study, 1315 patients with CL, who referred to the Dermatology and Leishmaniasis Research Center at Isfahan, were evaluated. Results: The highest prevalence of CL was observed in fall (54%) and in northern areas of Isfahan (60.9%). Although CL was prevalent in both men and women, it had higher incidence in men (61.8%). The majority of patients (31.2%) aged 21-30 yr old. Most lesions were nodule-shaped (36.5%) and in upper extremities (48.3%) particularly in men (32.4%). While 81.2% of the subjects were Iranian, others were Afghani or with other nationalities. Most patients had multiple lesions on their bodies and 141 individuals (10.7%) had a previous history of disease. Among all occupations, the highest prevalence of CL was detected in students (18.1%). The response to treatment with compounds of meglumine antimoniate (glucantime) was better than other treatments. Interpretation & conclusion: Unfortunately, the results showed that the prevalence of CL has been increasing annually in some provinces of Iran, especially in Isfahan Province. Nevertheless, further studies are required to determine the vectors, reservoirs, and species of disease and to design appropriate strategies to control the disease.

Free radical-induced neural damage is implicated in neurodegenerative diseases and antioxidants have protective activity. In the present study, we examined the effect of gallic acid (GA; 50, 100 and 200 mg/kg, p.o. for 10 days) on memory deficit and cerebral oxidative stress induced by 6-hydroxydopamine (6-OHDA; 8 μg/2 μL) injected into the medial forebrain bundle (MFB, full nigral lesion) as an animal model of Parkinson's disease (PD). The results showed that 6-OHDA significantly reduced the passive avoidance memory performance, non-enzymatic (total thiol) and enzymatic [glutathione peroxidase (GPx)] antioxidant contents and increased the level of malondialdehyde (MDA) in the hippocampus and striatum of vehicle-treated group as compared to sham-operated rats. Furthermore, oral administration of GA significantly increased the passive avoidance memory, total thiol and GPx contents and also decreased MDA levels in the above tissues. The results suggest that GA has neuroprotective activity against 6-OHDA-induced oxidative stress via enhancement of cerebral antioxidant defence. © 2012 Elsevier Ltd. All rights reserved.

Brachiopod fauna from central Iran, recorded in the upper part of the Shemshak Group and attributed to the upper Toarcian (Pseudoradiosa-Aalensis zones), are reported for the first time in Iran. The assemblage recognized includes six different taxa: Homoeorhynchia sepahanensis nov. sp., formally described in this paper, Globirhynchia subobsoleta, Pseudogibbirhynchia sp., Tetrarhynchiidae sp. indet., Monsardithyris? aff. haresfieldensis, and Zeilleria cf. leckenbyi. Analysis of faunal affinities with other paleobiogeographical regions shows a free connection of the central Iranian brachiopod fauna and wide areas of the northern shelf margin of the Tethys Ocean. This is due to an apparent disruption of bioprovinciality inferred for the late Toarcian-earliest Aalenian, congruent with a connection through the northern seaway across the peri-Laurasian epicontinental platforms. © 2014 Elsevier Masson SAS.
