abstract = {The impact of tick-borne pathogens (TBPs) on human health has increased in the last decades, since the incidence of emerging and re-emerging infectious and zoonotic tick-borne diseases has increased worldwide. Tick-borne rickettsiae of the Spotted Fever group (SFGR) are considered as emerging pathogens that can infect humans and cause a variety of non-specific clinical symptoms. Here, we report nine cases of atypical tick-borne diseases (9/460; 1.95%) that occurred over a period of four months (from 15 April 2021 to 16 August 2021) in Serbia, from which five cases were classified as confirmed SFGR infection, two cases as probable SFGR infection and two cases as suspected SFGR infection. Within cases of confirmed SFGR infection, R. helvetica was detected as the causative agent in two cases. The most common clinical finding was non-expanding persistent circular redness, followed by eschar and enlargement of regional lymph nodes, and pain at lesion site. Rickettsia outer membrane protein B (ompB) and citrate synthase (gltA) gene fragments were amplified from clinical samples and ticks attached to patients and IgG reacting with Rickettsia conorii antigen were detected in sera samples of patients, which are highly suggestive of exposure to SFGR. Surveillance and monitoring of rickettsial diseases in Serbia should continue and extended to new areas due to the increasing trend of clinical infections caused by SFGR in the country.},

abstract = {Ticks carry numerous pathogens that, if transmitted, can cause disease in susceptible humans and animals. The present study describes our approach on how to investigate clinical presentations following tick bites in humans. To this aim, the occurrence of major tick-borne pathogens (TBPs) in human blood samples (n = 85) and the ticks collected (n = 93) from the same individuals were tested using an unbiased high-throughput pathogen detection microfluidic system. The clinical symptoms were characterized in enrolled patients. In patients with suspected TBP infection, serological assays were conducted to test for the presence of antibodies against specific TBPs. A field study based on One Health tenets was further designed to identify components of a potential chain of infection resulting in Rickettsia felis infection in one of the patients. Ticks species infesting humans were identified as Ixodes ricinus, Rhipicephalus sanguineus sensu lato (s.l.), Dermacentor reticulatus, and Haemaphysalis punctata. Five patients developed local skin lesions at the site of the tick bite including erythema migrans, local non-specific reactions, and cutaneous hypersensitivity reaction. Although Borrelia burgdorferi s.l., Babesia microti, Anaplasma phagocytophilum, and Candidatus Cryptoplasma sp. DNAs were detected in tick samples, different Rickettsia species were the most common TBPs identified in the ticks. The presence of TBPs such as Rickettsia helvetica, Rickettsia monacensis, Borrelia lusitaniae, Borrelia burgdorferi, Borrelia afzelii, A. phagocytophilum, and B. microti in ticks was further confirmed by DNA sequencing. Two of the patients with local skin lesions had IgG reactive against spotted fever group rickettsiae, while IgM specific to B. afzelii, Borrelia garinii, and Borrelia spielmanii were detected in the patient with erythema migrans. Although R. felis infection was detected in one human blood sample, none of the components of the potential chain of infection considered in this study tested positive to this pathogen either using direct pathogen detection in domestic dogs or xenodiagnosis in ticks collected from domestic cats. The combination of high-throughput screening of TBPs and One Health approaches might help characterize chains of infection leading to human infection by TBPs, as well as prevalence of emerging rickettsial pathogens in the Balkan region.},

requires coordination among major stakeholders (such as veterinarians, physicians, acarologists,

and researchers) for the identification of exposure and infection risks and application of effective

prevention measures. In this review, we summarize our current knowledge on the epidemiology of

tick-borne diseases in Central America and the Caribbean and the challenges associated with the

implementation of ‘One Health’ surveillance and control programs in the region.},

abstract = {Tick-borne pathogens (TBPs) have complex life cycles involving tick vectors and vertebrate hosts. However, there is limited empirical evidence on the zoonotic circulation of TBPs. In this study, we used a One Health approach to study the possible circulation of TBPs in ticks, animals and humans within a rural household in the foothills of the Fruška Gora mountain, northern Serbia. The presence of TBP DNA was assessed using microfluidic PCR (25 bacterial species, 7 parasite species, 5 bacterial genera, 3 parasite genera) in animal, human and tick samples and the presence of tick-borne encephalitis virus (TBEV) RNA was screened for using RT-qPCR on tick samples. In addition, Lyme borreliosis serology was assessed in patient sera. Rhipicephalus sanguineus and Ixodes ricinus ticks were identified on dogs and Haemaphysalis punctata was identified on house walls. Rickettsia helvetica was the most common pathogen detected in pooled R. sanguineus and I. ricinus tick samples, followed by Hepatozoon canis. None of the H. punctata tick samples tested positive for the presence of TBPs. Anaplasma phagocytophilum and Rickettsia monacensis were the most frequent pathogens detected in dogs, followed by Rickettsia felis, whereas Anaplasma bovis was the only pathogen found in one of the goats tested. None of the human blood samples collected from family members tested positive for the presence of TBPs. Although microfluidic PCR did not detect Borrelia sp. in any of the tested tick or blood samples, a family member with a history of Lyme disease was seropositive for Borrelia burgdorferi sensu lato (s.l.). We conclude that, despite the presence of TBPs in tick and vertebrate reservoirs, there is no evidence of infection with TBPs across various components of the epidemiological chain in a rural Fruška Gora household.},

abstract = {Tick-borne encephalitis (TBE), caused by the TBE virus (TBEV), is a life-threatening disease

with clinical symptoms ranging from non-specific to severe inflammation of the central nervous

system. Despite TBE is a notifiable disease in Serbia since 2004, there is no active TBE surveillance

program for the serologic or molecular screening of TBEV infection in humans in the country. This

prospective cohort study aimed to assess the TBEV exposure among tick-infested individuals in

Serbia during the year 2020. A total of 113 individuals exposed to tick bites were recruited for the

study and screened for anti-TBEV antibodies using a commercial indirect fluorescent antibody test

(IFA) test. Blood samples from 50 healthy donors not exposed to tick bites were included as a control

group. Most of the enrolled patients reported infestations with one tick, being I. ricinus the most

frequent tick found in the participants. The TBEV seroprevalence was higher (13.27%, 15 total 113)

in tick-infested individuals than in healthy donors (4%, 2 total 50), although the difference was

not significant. Notably, male individuals exposed to tick bites showed five times higher relative

risk (RR) of being TBEV-seropositive than healthy donors of the same gender (RR= 5.1, CI = 1.6–19;

p = 0.007). None of the seropositive individuals developed clinical manifestations of TBE, but the first

clinical-stage of Lyme borreliosis (i.e., erythema migrans) was detected in seven of them. Potential

TBEV foci were identified in rural areas, mostly in proximity or within the Fruška Gora mountain.

We conclude that the Serbian population is at high risk of TBEV exposure. Further epidemiological

studies should focus on potential TBEV foci identified in this study. The implementation of active

surveillance for TBEV might contribute to evaluating the potential negative impact of TBE in Serbia.},

abstract = {Introduction. The primary objectives of this study were (1) to determine the presence of Borrelia burgdorferi infection in ticks removed from patients for the purpose of singling out sites with increased risk of Lyme borreliosis, and (2) to determine the presence of IgM and/or IgG antibodies against B.  burgdorferi  sensu lato (s. l.) complex in sera of patients who had ticks removed 

Materials  and  Methods.  From  108  ticks  removed  from  patients,  all  were  examined zoologically and a sub-sample of 91 ticks was tested using PCR analysis to determine the presence of DNA indicating B. burgdorferi infection. To detect anti-Borrelia IgM and/or IgG antibodies in 61 patients bitten by ticks, we used line recombinant immunoblot test.

Results and Conclusions. The most common tick identified was Ixodes ricinus. B. burgdorferi s. l. was present in 37 of 91 tested ticks (40.7%). Seroconversion against B. burgdorferi s. l. antigen was detected in 12 of 61 patients (19.7%). Most of the infected ticks were from the province of Vojvodina (11 municipalities), with the city of Novi Sad proving to be the site with the highest number of infected ticks, 6 in total. },
