Background: The viability and persistence of engineered bacterium candidates in field conditions is one of the considerable challenges in the paratransgenesis approach to fighting vector-borne diseases. Methods: In this study two engineered bacterium candidates to produce paratransgenic sand flies, Serratia AS1 and Enterobacter cloacae expressing m-Cherry fluorescent were applied on the leaves of the white saxaul plant (Haloxylon persicum), sugar bait, and rodent burrow soil and their persistent time was tested in desert condition, Matin Abad County, Isfahan, August 2022. A PBS suspension of 109 cells/ml was used for sugar bait, spraying on plant leaves (~10 cm2) and 10 cm2 of rodent burrow soil. Sand fly samples were taken daily and were plated on LB Agar and the fluorescent cells were counted after 24 hours. Results: Time course in general caused a decrease in the number of bacteria for both strains. The two strains were persistent in sugar bait and on plant leaves for four days and on soil for two days. Although there were slight differences between the number of the bacteria in sugar baits, which was not significant (P< 0.05). The number of E. cloacae surviving on plant and in soil were significantly (P< 0.0001 and P= 0.046) higher than Serratia AS1. Conclusion: This study shows that plants or sugar bait are useful routes for delivery of the transformed bacteria for the paratransgenesis approach, although, the bacteria ought to be sprayed on plants or sugar baits should be replaced with new ones in four days intervals.

Background: Babesia ovis, an intraerythrocytic parasite carried by ticks and one of the most common subclinical ovine illnesses, was studied to ascertain its seroprevalence and endemic status in ram and ewe populations in East Azerbaijan Province, Iran, in lambs, yearlings, and adults of over two years of age. Methods: A total of 960 sheep from 10 cities were selected from Jan 2018 to Nov 2019. Blood samples were collected from each animal and tested for the presence of B. ovis antibodies by applying a developed enzyme-linked immunosorbent assay (ELISA) technique. Checkerboard titrations were used to determine the optimal dilution of the antigen using negative and positive control sera. To determine whether the disease is endemically stable, inoculation rates for each age group were also calculated. Correlation coefficients were calculated between age and infection rates and also between age and inoculation rates. Results: The results revealed an average infection rate of 49.4% in East Azerbaijan Province. There was a positive correlation between the age of animals and susceptibility to infection except for lambs and yearlings, whereas there was no meaningful difference in exposure to B. ovis between rams and ewes. The negative correlation between age and inoculation rates indicates increased disease instability with age. Inoculation rate results revealed the endemically instable status of B. ovis in the studied area. Conclusion: High prevalence rates and endemically instable status of the disease suggest demand for vaccine development and implementation of appropriate control measures for ovine babesiosis to mitigate the associated economic losses.

Background: Zoonotic cutaneous leishmaniasis (ZCL) is widely distributed in Iran and around the world. Also, Khuzestan Province is an endemic focus of ZCL. This study aims to investigate the natural infection of sand flies with the Leishmania parasite in Karun County. Methods: Sand flies were collected from Jangiyeh, Qaleh Chanan, Kut-e-Navaser, and Ghazavieh in the spring and summer in the year of 2019, by installing 60 sticky paper traps each time (30 traps outdoors and 30 traps indoors). Two hundred female sand flies with different abdominal conditions (empty, blood-fed, semi-gravid, and gravid) were examined for infection rate using the Nested-PCR method. Results: In this study, seven species of sand flies including Phlebotomus papatasi, Ph. alexandri, Ph. sergenti, Ph. caucasicus, Sergentomyia tiberiadis, Se. sintoni, and Se. antennata were reported from Karun County, with a frequency of 79.64%, 16.96%, 1.07%, 0.18%, 0.36%, 1.61%, and 0.18%, respectively. Only eleven specimens of Ph. papatasi were found to be positive for Leishmania major, with an overall infection rate of 7.8%. The infection of Ph. papatasi was specifically reported in blood-fed, gravid, and semi-gravid specimens, with infection rates of 17.02%, 4.35%, and 14.29%, respectively. Conclusion: In this study, the infection of L. major from Ph. papatasi was reported. The results can be used in planning the control of ZCL in the study area.

Background: The common bed bugs, Cimex lectularius, and tropical bed bugs, Cimex hemipterus are the primary species of public health importance in the family Cimicidae. This study aimed to determine the morphometric criteria and prevalent species of bed bugs in eastern Iran. Methods: Bed bugs were collected from March 2021 to June 2022 from infested residential buildings and apartments in eastern Iran, including North Khorasan, Khorasan Razavi, and Sistan and Baluchistan Provinces. The morphological and morphometrical characteristics were used to identify collected bed bugs at inter- and intra-specific levels. Results: A total of 34 isolates comprising 127 adult bed bugs were collected from Bojnord, Mashhad, Neishabur, Taibad, Sabzevar, Kashmer, Zahedan, Saravan, Rask, Pishin and Chabahar. Of these, 33 isolates (n=124) were found to be tropical bed bugs, C. hemipterus, and one population (n=3) was identified as C. lectularius. The index pronotal width/length ratio was calculated from 2.72 to 2.94 and 1.98 to 2.47 for C. lectularius and C. hemipterus, respectively. The length/width ratio of the hind femur was 3.365 in C. hemipterus and 4.267 in C. lectularius. The ratio of length/width of the third femur (F3 l/w) between populations of C. hemipterus was different, and this difference was statistically significant (P< 0.05). Conclusion: The results of this study indicated that C. hemipterus was the dominant bed bug species in the east of Iran and provided more morphometric criteria of C. hemipterus for researchers to identify the species and determine the intraspecific variations in the present and future.

Background: Head louse infestation, pediculosis, is a serious health problem worldwide. Infected children usually suffer from itching, allergies, and secondary infections besides psychological disorders such as depression and lack of self-confidence leading to school failure. This study aimed to investigate the status of pediculosis and its determinant factors among schoolchildren in Amol City, Northern Iran. Methods: This study included 228 schools frequented by about 20017 students. Pediculosis was determined by careful examination of students’ hair on the scalp, back of the neck, and around the ears. The diagnosis was based on observation of live adults, nymphs, and nits. A questionnaire was used to record the personal and demographic characteristics of participants. Results: This study revealed that the prevalence of pediculosis among schoolchildren during all schooling seasons (autumn, winter, and spring) correlated with sex: the prevalence being higher among girls than boys (p= 0.00). In addition, the highest rates of pediculosis occurred during the autumn season (p= 0.00). The public schools accommodated higher numbers of louse-infected students than the private ones (p= 0.00). While head louse occurred at higher frequencies in long hair over the schooling year, dandruff had anti-louse effects (p= 0.00) during cold seasons, autumn, and winter. Socioeconomic status and educational level of parents played determinant roles in head louse prevalence (p= 0.00). Schoolchildren coming from socioeconomically well-situated families had lower rates of head louse infestation. Conclusion: Our results showed that head pediculosis was a serious health problem among schoolchildren in Amol city and its prevalence and severity tended to be multifactorial.

Background: Tularemia is a zoonotic disease (reservoir is usually rodents) caused by Francisella tularensis, especially seen in the northern hemisphere. Hunters are in the risk group for this disease. In this study, it was aimed to determine the seroprevalence of tularemia among hunters and determine the risk factors of tularemia in our country. Methods: The Turkish Republic of Northern Cyprus (TRNC) is divided into four regions (Nicosia, Kyrenia, Famagusta/Trikomo, and Morphou/Lefka) and 100 volunteer hunters randomly selected from these regions were included in our study. Tube agglutination test (TAT) and F. tularensis IgG and IgM (ELISA method) were applied in all sera. All hunters were filled with a pre-prepared questionnaire to determine risk factors for tularemia. Results: TAT positivity was found in 11%. While F. tularensis ELISA IgG positivity was 17%, IgM positivity was not found in any hunters. Hunters with positive F. tularensis ELISA IgG test (17%) were accepted as seropositive in terms of tularemia. There was no statistically significant difference between the mean age of IgG-positive and negative hunters (p= 0.915). Of the 86 hunters who kept at least one hunting dog in their garden, 15 (17.4%) were IgG-positive. There was no significant relationship between feeding hunting dogs and tularemia (p= 0.561). Conclusion: Our study showed that the seroprevalence of tularemia was high (17%) among hunters, who are considered a risk group, in our country. We think that more epidemiological research should be done on tularemia infection and it should not be overlooked in the clinic.

Background: Q fever is a contagious zoonotic disease which is caused by a gram-negative and intracellular Coccobacillus known as Coxiella burnetii ticks play a role in its transmission. Endocarditis is the most common consequence of chronic Q fever. Methods: Here we report a case of endocarditis caused by Q fever. The patient is a 67-year-old, and she had coronary artery bypass graft (CABG) and aortic valve replacement surgery. Results: The result of echocardiography showed a suspicious mass (Vegetation) on the implanted valve. Based on laboratory and clinical assessments, endocarditis caused by C. burnetii was the final diagnosis. Conclusion: Q fever is a tick-transmitted pathogen that has been known as an important cause of culture-negative endocarditis in Iran, and more attention needs to be paid to this disease in Iran by the healthcare system and physicians.

Background: This study's major aim is to investigate the situation of visceral leishmaniasis vectors, with a focus on their distribution and relationships to the disease in Iran and some other old-world nations. Methods: The terms Iran and the Old World, along with the keywords sand flies, vectors, visceral leishmaniasis, distribution, and Phlebotomus, were searched in electronic databases from 1930 to 2018, including Pub-Med, Web of Science, Google Scholar, and MEDLINE. Results: According to the findings, Phlebotomus tobbi was a mountain species, but it was also found in the plains, rodent nests, and rock crevices. This species was considered to be one of the vectors of visceral leishmaniasis in Iran. Phlebotomus kandelakii has been caught in Afghanistan, Iran, Lebanon, Turkey and Georgia. In Iran, the first infection of Phlebotomus kandelakii and Ph. perfiliewi transcaucasicus with Leishmania infantum were reported in northwest of Iran. Phlebotomus major was one of the complex sand flies, and its members include Ph. major (India, Nepal, and Pakistan), Ph. neglectus (Southern Europe, Crimea and Iran), Ph. syriacus (Southwest Asia, Caucasus), Ph. notus (Afghanistan and Iran), Ph. wenyoni (Iran and Iraq), and Ph. wui (China). The first natural infection of Ph. alexandri with Leishmania infantum was reported in 2006 in endemic foci of visceral leishmaniasis in Fars Province, southern Iran. Conclusion: The findings of this project suggest that sand fly species of the subgenus Larrousisus play a key role in the transmission of all types of visceral leishmaniasis in Iran.
背景：本研究的主要目的是调查内脏利什曼病病媒的情况，重点是它们在伊朗和其他一些旧世界国家的分布及其与该疾病的关系。研究方法：以伊朗和旧世界为术语，以沙蝇、病媒、内脏利什曼病、分布和Phlebotomus为关键词，在1930年至2018年的电子数据库中进行了检索，包括Pub-Med、Web of Science、Google Scholar和MEDLINE。结果：根据研究结果，Phlebotomus tobbi是一种山区物种，但在平原、啮齿动物巢穴和岩石缝隙中也有发现。该物种被认为是伊朗内脏利什曼病的病媒之一。阿富汗、伊朗、黎巴嫩、土耳其和格鲁吉亚都曾捕获过 Phlebotomus kandelakii。伊朗西北部首次报告了 Phlebotomus kandelakii 和 Ph. perfiliewi transcaucasicus 感染婴儿利什曼病。Phlebotomus major 是复合沙蝇之一，其成员包括 Ph. major（印度、尼泊尔和巴基斯坦）、Ph. neglectus（南欧、克里米亚和伊朗）、Ph. syriacus（西南亚、高加索）、Ph. notus（阿富汗和伊朗）、Ph. wenyoni（伊朗和伊拉克）和 Ph. wui（中国）。2006 年，在伊朗南部法尔斯省的内脏利什曼病流行区，首次报告了 Ph. alexandri 与婴儿利什曼原虫的自然感染。结论本项目的研究结果表明，Larrousisus 亚属的沙蝇物种在伊朗各种类型的内脏利什曼病传播中起着关键作用。

Background: Malaria has remained the most dreadful vector-borne disease; hence, vector control is the most affordable and achievable approach to mitigate the disease burden. Due to the emergence of resistance and environmental pollution, herbal larvicides are considered an alternative to chemical types. Also, nanotechnology has been proposed as a promising solution to improve the efficiency of plant larvicides. This study aimed to develop an effective herbal larvicide. Methods: The chemical composition of Elettaria cardamomum essential oil (EO) was first investigated. Nanoliposomes containing the EO were then prepared using the ethanol injection method. After that, the larvicidal efficacy of the EO and its liposomal state were compared against Anopheles stephensi in laboratory conditions. Results: Alpha-terpinyl acetate (77.59%), eucalyptol (4.38%), nerolidol (2.96%), linalool (1.77%), and limonene (1.69%) were the five major compounds of the EO. Nanoliposomes containing the EO with a particle size of 73±5 nm and a zeta potential of -16.3±0.8 mV were prepared. Additionally, the ATR-FTIR analysis verified the successful loading of the EO into nanoliposomes. The larvicidal activity of nanoliposomes exhibited remarkable potency, with an LC50 value of 14.35 (10–18) µg/mL, significantly more potent than the non-formulated EO, which had an LC50 value of 33.47 (28–39) µg/mL against Anopheles stephensi larvae. Conclusion: The nanoliposomes containing E. cardamomum EO showed promising efficacy against An. stephensi larvae. It could thus be considered for further application against other species of mosquitoes.

Background: Phlebotomus papatasi (Diptera: Psychodidae) is the main vector of zoonotic cutaneous leishmaniasis (ZCL) in Iran. The nonstandard use of pesticides against pests, particularly in agriculture, indirectly has caused the development of resistance and, consequently, the threat of control measures in ZCL endemic areas. Up to 2023, several reports of resistance in Ph. papatasi have been declared in the Old World. The purpose of this study was to measure the lethal time (LT50 and LT90) of Ph. papatasi sand flies in the ZCL endemic center of Esfahan to DDT and deltamethrin insecticides. Methods: Sand flies were collected in Borkhar and were tested using WHO adult mosquito test kit against DDT 4% and deltamethrin 0.0002%. The sand fly’s survival was recorded during exposure time in 225, 450|, 900, 1800, and 3600-seconds’ intervals for DDT and Deltamethrin and they were allowed to recover for 24 hours. Then LT50 and LT90 were analyzed using probit software. Phlebotomus papatasi were identified using morphological keys and other sand flies’ species were excluded from the analysis. Results: The insecticide against female Ph. papatasi revealed hundred percent mortality when exposed to DDT 4% and deltamethrin 0.0002%. The LT50 and LT90 were 19.32 and 22.74 minutes for DDT 4% and 39.92 and 51.33 minutes for deltamethrin 0.0002% respectively. Conclusion: Results of this study revealed that Ph. papatasi is still susceptible to DDT and deltamethrin. This data provides valuable knowledge to implement effective control strategies against ZCL main vector and help to manage insecticide resistance in the region.
