Abstract
Background Medico legal forensic entomology is the science and study of cadaveric arthropods related to criminal investigations. The study of beetles is particularly important in forensic cases. This can be important in determining the time of death and also obtain qualitative information about the location of the crime. The aim of this study was to introduce the Saprinus planiusculus on a rat carrion as a beetle species of forensic importance in Khuzestan province. Methods This study was carried out using a laboratory bred rat (Wistar rat) as a model for human decomposition. The rat was killed by contusion and placed in a location adjacent to the Karun River. Observations and collections of beetles were made daily during May to July 2015. Results Decomposition time for rat carrion lasted 38 days and S. planiusculus was seen in the fresh to post decay stages of body decomposition and the largest number of this species caught in the decay stage. Conclusion The species of beetle found in this case could be used in forensic investigations, particularly during the warm season in the future.

Abstract
OBJECTIVE Crimean-Congo haemorrhagic fever (CCHF) is a viral zoonotic disease with potentially fatal systemic effects on man. We aimed to determine the presence of CCHF virus among collected ticks from domestic livestock from October 2012 to September 2013. METHODS A total of 1245 hard and soft ticks were collected from naturally infested ruminants in Marvdasht County, Fars Province, south of Iran. Nine tick species and one unidentified species in four disparate genera were detected. A total of 200 ticks were randomly selected and analysed by reverse transcription-polymerase chain reaction (RT-PCR) for the presence of CCHF virus genome. RESULTS The viral genome was detected in 4.5% (9 samples) of the studied tick population. The infected ticks belonged to the species of Hyalomma marginatum' Hyalomma anatolicum and Rhipicephalus sanguineus. The viruses detected in these three tick species were clustered in the same lineage as Matin and SR3 strains in Pakistan and some other Iranian strains. These results indicate that the ticks were wildly infected with a genetically closely related CCHF virus in the region. CONCLUSION Regular controls and monitoring of livestock to reduce the dispersion of ticks and providing information to those involved in high-risk occupations are urgently required.

Abstract
Human cutaneous leishmaniasis (CL) is a major notifiable public health problem in many parts of Iran. It is often caused by the zooflagellate parasite Leishmania major which is mainly transmitted by the bites of female phlebotomine sandflies belonging to the genus Phlebotomus (Diptera: Psychodidae). The annual incidence of CL in Fars province, southern Iran, was about 108-144 in 2007. The leishmanial infections of wild sandflies that may act as vectors were thus investigated at an endemic focus in this province. In all 330 female Phlebotomus sandflies were screened for the detection of Leishmania-specific kinetoplast DNA (kDNA) by polymerase chain reaction (PCR) methods. A two stage nested PCR protocol was used to establish the identity of Leishmania major species in naturally infected sandflies. The L. major kDNA was detected in 18 (5.5%) individual sandflies which belonged to four different Phlebotomus species (Phlebotomus papatasi, Phlebotomus salehi, Phlebotomus sergenti and P. major group). For the first time, one naturally infected P. salehi specimen contained the kDNA of the protozoan parasite, L. major, with a main band of 560 base pairs identified using the nested PCR method. It seems most likely therefore that P. salehi is potentially a rare sylvatic vector of L. major parasites in parts of this province. This is the first combined morphological and molecular studies of P. salehi in Iran.

Abstract
Gerbillus nanus Blanford, 1875 known as Baluchistan gerbil, is a granivorous solitary naked-footed species. No evidence of its natural infection with the protozoan parasite, Leishmania, has so far been provided. Cutaneous leishmaniasis (CL) is a major public health problem in many parts of the world, including Iran. The annual nationwide incidence of human CL due to Leishmania major (CLM) in endemic rural areas was above 18,000 cases in 2008. The detection of L. major in rodents is of fundamental importance for incriminating them as potential reservoirs of CLM infection. Between April 2007 and April 2008, following detection of 245 clinical cases in Jask region of south-east Iran, wild rodents were captured and checked by the microscopic slide smears for leishmanial infections. Overall, 106 gerbilline rodents were captured from which 17 were identified as Gerbillus nanus. Females of Meriones hurrianae, Tatera indica and G. nanus were found to be naturally infected with L. MAJOR. The presence of these parasites in G. nanus has never been reported before. All the amastigote-infected rodents came from the eastern plain of this region, except one T. indica from the western plain which was found to be smear-positive or kinetoplast DNA-positive by PCR. The highest (11·8%) prevalence of infection among rodents confirmed by PCR to be infected with L. major was attributed to Baluchistan gerbil, G. nanus, which is thus incriminated as a potential reservoir host of L. major in Iran.

Abstract
Human cutaneous leishmaniasis (CL) is of increasing public-health importance in Iran. On 10 July 2003, two mild earthquakes struck the rural town of Zarindasht in the southern Iranian province of Fars. The results of passive detection of CL cases in this town (in which patients with any skin lesions were evaluated) from April 2002 to April 2004 indicated that the earthquakes may have led to an outbreak of the disease; annual incidence increased from 58·6 detected cases/100,000 in the 12 months before the earthquakes to (an outbreak peak of) 864 detected cases/100,000 in the following 12 months. In addition, the incidence of detected CL in the town that was struck by the earthquakes in 2003 was significantly higher in the 12 months after the earthquakes than that recorded, over the same 12 months, for Fars province as a whole (P<0·05). Most (70%) of the cases detected in the town were aged ≤10 years, about half (50·4%) of the detected skin lesions were on the face, and most (89·7%) of the skin lesions were caused by Leishmania major. Incidence over the study period showed marked seasonality, with most (79·5%) of the detected cases occurring between November and February. In areas where the disease is endemic, CL may need to be considered among the health threats posed by natural disasters such as earthquakes, and increased surveillance for CL after future earthquakes may be justified.

Abstract
Linear dermatitis (or dermatitis linearis, DL) is a skin blistering inflammatory lesion caused by exposure to the pederin toxin from rove beetles. Although it is prevalent in many countries of the Middle East region, this is not a notifiable disease. In recent years, a number of clinical symptoms outbreaks of DL has been reported from a few neighboring countries of Iran, but no report of experimental treatment among small laboratory rodents is known. This is a prerequisite to ascertain the nature of the best treatment strategy in cases of infestation with these beetles, as it occurs among local settlers during hot seasons in certain parts of the southern Iranian province of Fars. Live Paederus beetles were collected, identified to species level, sexed apart and partly processed to obtain their hemolymph toxin pederin in ethanol for dermal application on guinea pigs. Two Paederus species were found. Paederus ilsae (Bernhauer) (Coleoptera: Staphylinidae) was more abundant than P. iliensis (Coiffait). Recovery from DL due to live P. ilsae beetles was quicker and less complex than that of pederin in ethanol on guinea pigs. The application of potassium permanganate with calamine to heal DL was also more effective than fluocinolone treatment. This topical corticosteroid is thus considered less able to avert the cytotoxic action of pederin on the skin of guinea pigs than the antipruritic and cleansing agents. It seems likely that fluocinolone has certain effects which delays the recovery period for the treated skin.

Abstract
Continuous and indiscriminate use of pesticides, especially in tropical countries for public health or agriculture purpose, has led many vector populations to become resistant to organochlorides, organophosphates, and even to carbamates and pyrethroids. Development of resistance by a vector population has been one of the reasons for the failure of the control measures in many countries. This investigation demonstrates the efficacy of piperonyl-butoxide (PBO) with deltamethrin, as pyrethroid insecticide, against the field-collected mosquitoe larvae of five species, Aedes aegypti, Anopheles culicifacies, An. stephensi, An. vagus, and Culex quinqufasciatus, and two morphological variants of Cx. tritaeniorhynchus (type A from grand pools of Mysore city and type B from rice fields of Mandya district). For testing the synergistic effect of PBO, stock solutions of deltamethrin and PBO were mixed in 1:6 ratio. The synergistic ratio and the percent suppression in deltamethrin tolerance were calculated by using LC(50) values. From the results, it is clear that, PBO is an effective synergist with deltamethrin against all of species undertaken in this investigation. So, it is suggested that PBO is a good synergist in this area for decreasing the use of pesticides in environment in vector control.

Abstract
The main purpose of this study was to assess the pulmonary reactions associated with exposure to raw materials used in ceramic production (RMCP). This was a cross sectional study in which 33 male workers with current exposure to RMCP and 20 healthy male unexposed workers (referent group) were interviewed and respiratory symptom questionnaires were administered to them. Furthermore, they underwent chest X-ray and lung function tests. Additionally, personal dust monitoring for airborne inhalable and respirable dust was carried out at dusty areas of the industry. To determine the chemical composition, possible silica phases and SiO(2) contents of dust samples, they were analyzed by both X-ray diffraction (XRD) and X-ray fluorescence (XRF) techniques. Demographic and socioeconomic variables of both groups were similar, except that referent individuals were, to some extent, older and heavier than their exposed counterparts. Personal dust monitoring showed that the concentrations of inhalable and respirable dust were very high and dust contained large amounts of crystalline silica. Additionally, respiratory symptom questionnaires revealed that exposed workers, compared to their unexposed counterparts, had higher prevalences of cough, wheezing, phlegm and shortness of breath. Likewise, significant decrements in some parameters of pulmonary function were noted and most of the exposed subjects showed abnormalities in their chest radiographs. These data provide further evidence in favor of the notion that exposure to RMCP, probably due to their silica contents, is associated with respiratory symptoms, radiographic abnormalities and functional impairments.

Abstract
Development of insecticide resistance has been a challenging problem for a long time and new solutions are yet to emerge. In this regard, the use of synergist with the insecticide is thought to play a key role in reducing the resistance levels. Present study demonstrates the efficacy of PBO with deltamethrin against the field collected mosquito larvae of five species of Aedes, Anopheles and Culexfrom in and around Mysore.

Abstract
Studies on Culex tritaeniorhynchus Giles, were undertaken to find deviation if any, on the mean of siphonal index, comb scales, pecten teeth, denticles on apical pecten tooth, anal gills index and length of basal hair tufts on siphon in the fourth instar larvae from ground pools of Mysore city and paddy fields outside Mysore. A total of 344 larvae including 172 samples from Mysore and 172 samples from a 26 km radius outside Mysore were collected. Analysis of variance demonstrated significant differences between the two populations on 7 parameters based on morphological characteristics such as comb scales, length of siphon, width of siphon at the middle, length of anal gills, siphonal index, anal gills index and the length of basal hair tufts. So Cx. tritaeniorhynchus from different breeding places in and around Mysore city in south India can be different varieties. One variety comparatively has shorter siphon index ratio, less comb scales, less anal gills index ratio and longer basal hair tufts on siphon than the other one. Mating behavior of these varieties show that, variety from the city pools was moderate eurygamous and the one from mainly paddy fields, moderate stenogamous.
