Abstract
Crimean-Congo hemorrhagic fever (CCHF) is an infection caused by a tick-borne virus (genus: Nairovirus, family: Bunyaviridae). The most important vector for CCHF is the ixodid tick. Along with tick bite, direct contact with the virus-affected animal is responsible for its spread. Pakistan witnessed its first case of CCHF in 1976 and has been a major victim of CCHF for years, but spikes in cases are seen after Eid-ul-Adha, an Islamic festival involving the sacrifice of cattle. The disease, in particular, is common among butchers, veterinarians, and livestock workers. From the start of this year till June 22, 2022, a total of four cases have been reported across the country. Pakistan faces major challenges in combating CCHF every year due to its specific geographical position and a majority of the population being involved with animal husbandry. There is no approved vaccine for its prevention. All these factors contribute to the burden on the already weakened healthcare system of Pakistan. Strict actions should be taken to contain the spread of the disease. The need of the hour is to engage the general population, raise awareness, and develop policies to ensure disease surveillance. This should be accompanied by fostering collaboration among animal and human health departments for efficient communication and early intervention. The focus should be on medical research to find an efficacious treatment and prophylaxis for the CCHF virus, which will be the cornerstone of future CCHF prevention and control strategies.

Occurrence, genetic characterization, and zoonotic importance of Giardia duodenalis in various species of rodents (Mus musculus, Rattus norvegicus, and Rattus rattus). Comp Immunol Microbiol Infect Dis 2022; 85:101812.

Abstract
Giardia duodenalis is a well-known flagellated parasite and the causative agent of protozoal diarrhea in animals and humans worldwide. Current study was aimed at determination of G. duodenalis prevalence, genetic variation and zoonotic significance in various species of rodents in Shiraz, southwestern Iran. In brief, 120 fecal specimens were collected from rodents (Rattus rattus, Rattus norvegicus, and Mus musculus) during May up to November 2021 and microscopically examined for Giardia cysts. Further molecular characterization of positive samples was done by nested-PCR, followed by nucleotide sequencing of the triose phosphate isomerase (tpi) gene. A total prevalence of 3.3% (4/120) was observed in rodents, with highest rate in black rats [5% (2/40)]. Regarding brown rats and house mice, only one sample was found to be positive, showing 2.5% and 2.5% prevalence, respectively. It is noteworthy that Giardia B and G assemblages were found in black rats (one case/genotype), whereas the only positive samples from brown rats and house mice were characterized as assemblage G. The major findings of the present study were the presence of both zoonotic and non-zoonotic Giardia assemblages in examined rats in Shiraz and the potential of black rats to harbor Giardia infection to humans. These concerns should be taken seriously in terms of public health. Nevertheless, the true epidemiology and assemblage distribution of Giardia is still open to question.

Infection of hard ticks in the Caspian Sea littoral of Iran with Lyme borreliosis and relapsing fever borreliae. Ticks Tick Borne Dis 2020; 11:101500.

Abstract
The Caspian Sea littoral of Iran is home to various hard tick species, including Ixodes ricinus, the notorious vector of Lyme borreliosis (LB) in Eurasia. Here, in this area, we examined I. ricinus and other hard ticks, along with common rodents and small mammals for LB and relapsing fever (RF) borreliae infection. Ticks were collected from various mammalian hosts, including sheep, goats, cattle, camels, horses, dogs, donkeys, rodents, and hedgehogs. Rodents and small mammals were live-captured from different habitats. A real-time PCR for 16S rRNA sequence revealed borrelial DNA in 71 out of 501 (≈14 %) specimens belonging to I. ricinus and Rhipicephalus ticks. None of the rodents and small mammals showed borrelial infection in the viscera. PCR amplification and sequencing of a 600-bp sequence of the flaB identified Borrelia bavariensis, Borrelia garinii, Borrelia afzelii, and Borrelia valaisiana, and the RF Borrelia, B. miyamotoi in I. ricinus ticks. The RF-like Borrelia in Rhipicephalus ticks shared the highest identity (98.97 %) with an isolate infecting Haemaphysalis megaspinosa ticks in Japan. Our phylogeny and BLAST analysis suggest the range extension of the European I. ricinus-associated borreliae into the north of Iran.

Abstract
Background and Aim: Zoonotic rodents (Rodentia: Muridae: Gerbillinae) and Phlebotominae sand flies are the major reservoir hosts and vectors of Leishmania major causing zoonotic cutaneous leishmaniasis, respectively. This study was carried out to evaluate the epidemiological aspects of cutaneous leishmaniasis (CL) in Tangestan County, Southwest Iran.
Materials and Methods: This descriptive cross-sectional study was carried out on human cases, probable reservoirs, and vectors of CL at Tangestan County in 2017. The data of patients were taken on health centers and analyzed. To determination faunistic of sand flies, they were collected using sticky paper traps and identified using identification keys. The rodent samples were captured using Sherman live traps and determined for amastigote infection.
Results: A total of 436 cases occurred during 2005-2017 and the incidence rate of disease was 0.2-12/100,000 people. Six species of sand flies including three species of Phlebotomus and three species of Sergentomyia including Phlebotomus papatasi, Phlebotomus sergenti, Phlebotomus alexandri, Sergentomyia tiberiadis, Sergentomyia baghdadis, and Sergentomyia clydei were identified. From 185 trapped rodents, 9 species were identified. We founded, 2 out of 132 Tatera indica (1.53%) were positive with Leishmania spp. using the microscopic method.
Conclusion: According to the existence of human leishmaniasis cases as a host, T. indica with high abundance and infected to Leishmania as a reservoir, and existence of P. papatasi with high abundance as a suspected vector of disease; there is a potential for transmission of disease in the area. Design of exact control and prevention strategies is highly recommended.

Abstract
Floods are one of the natural disasters occurring worldwide which have a massive range of health impacts. In addition to immediate dangers such as drowning, floods can increase the transmission of some communicable diseases. Up to now there was no report of viral infection outbreaks after 2019 spring floods in Iran. This review explains the possible viral infections which may occur during or after floods.
