Despite the increasing of onychomycosis caused by Candida spp., in referent literature, there is still data insufficiency about this nail infection. The objectives of this retrospective study were to determine epidemiological characteristics of Candida onychomycosis, the antifungal susceptibility of isolated species in vitro, and to compare the results of antifungal susceptibility testing with conducted treatment in period from 2011 to the end of March 2015. Out of 761 patients who were underwent clinical and mycological examinations, 137 had Candida species isolated from nails. The dominant species was Candida albicans (C. albicans) (36.59%) followed by C. parapsilosis (23.78%), C. krusei (9.76%), and C. guilliermondii (6.71%). Antifungal susceptibility in vitro testing showed good susceptibility to antimycotics, except C. krusei, which was resistance to fluconazole (FCZ) and isolates of C. tropicalis and C. glabrata which were dose dependent to itraconazole (ITZ) and fluconazole. Evaluation of medical histories determined that combined therapy, which included pulsed systemic regimen of ITZ with topical application of clotrimazole, had better clinical outcomes regarding the proscribed only topical application of clotrimazole. Multidisciplinary approach of dermatologists and mycologists is required in solving the problem of onychomycosis, which is the dominant nail disease.

During the years 2012-2014, a total of 158 outdoor dogs from Pančevo and Đurđevo (northern Serbia) and Niš and Prokuplje (southern Serbia) were submitted to molecular analyses (PCR and sequencing) for canine babesioses. An overall prevalence of 21.5% was found, due to the species Babesia sp. 'spanish dog' (10.1%), B. gibsoni (5.7%), B. canis vogeli (1.9%), B. caballi (1.9%), and B. microti (1.9%). In addition, sequence analysis showed the presence of Hepatozoon canis in a dog from Niš. No significant difference between infected and noninfected dogs was found by age, sex, and place of residence, whereas there was difference regarding the presence of ticks (p<0.005) and application of preventive measures such as applying of antitick drugs/devices. Moreover, a significant difference was established by area: Dogs from Prokuplje showed infection rates (59.1%) higher than dogs from Pančevo (11.9%), Niš (4.5), and Đurđevo (where infected dogs were not found), and a different geographical distribution of the species was found. The presence of so many Babesia species and the first identification of H. canis will allow investigations on the pathogenic role played by each one and suggests entomological studies on the tick species that are more suitable vectors for each of them. Finally, the presence of so many infected dogs offers the opportunity of evaluating the hypothesis of a possible zoonotic role of babesial species affecting dogs.

In 2009 canine filarial infections were investigated in two northern areas of Serbia (Pančevo and Veliko Gradište), applying morphometry, biochemical staining, and immunological kit to detect Dirofilaria immitis antigens, and two home-made ELISAs to detect antibodies to D. repens and D. immitis somatic/metabolic polyproteins. Moreover, molecular tools were applied to analyze the phylogenetic relationships of the isolates. The microfilariae detected in 21/122 dogs (17.2%) were identified as D. repens (n=21) and D. immitis (n=2). D. immitis antigens were found in another 13 animals with occult infection. All of the 15 heartworm-positive dogs also had antibodies to this parasite, which were detected in another 13 subjects, indicating an overall D. immitis seroprevalence rate of 22.9%. Serology for D. repens revealed evidence of antibodies in 42.6% of the dogs, but was negative for 4 microfilaremic dogs. As for the two different areas, the prevalence of microfilariae and/or D. immitis antigens, mainly due to D. repens microfilaremic animals, was not significantly higher in Veliko Gradište (33.3%) than in Pančevo (22%). However, serology showed a different epidemiological picture. Heartworm infection occurred more often in both areas, and antibodies to dirofilarial nematodes were detected in 72.9% of dogs living in Pančevo, a rate higher than in those living in Veliko Gradište (57.1%). No risk factors for infection were found, confirming the uselessness of prophylactic drugs against D. repens, and suggesting the presence in these areas of sunrise- or sunset-biting mosquitoes as important vectors. The results indicate the need for both appropriate entomological studies and further research on the intra-species variability shown by D. repens.

BackgroundThe Northern part of Serbia is hyperendemic-endemic for canine dirofilarioses. Considering this fact, many human dirofilarial infections could be expected, however only about 30 cases in Serbia have been described until today. Aims of this survey were to assess the people reactivity to the antigens of D. repens and D. immitis and to identify risk factors for the contact exposure.MethodsInvestigation included sera taken from 297 people (179 women and 118 men) living in different areas of Serbia (Pančevo, Novi Sad, Zaječar, Leskovac, Vranje, Niš, Pirot). Sera were analysed by means of two indirect enzyme-linked immunosorbent (ELISA) home-designed that use as antigens adult somatic/metabolic polyproteins of D. repens (DR) and D. immitis (DI), respectively. The results were elaborated using the statistical method of descriptive and quantitative analysis.ResultsSignificant differences by area in the reactivity of human sera to dirofilarial antigens were not observed (p = 0.056). A high seroreactivity was demonstrated in people from the towns of northern Serbia (Pančevo = 27,1%; Novi Sad = 16,3%), as well as in people from Zaječar (eastern Serbia = 15,8%) and Vranje (southern Serbia = 15,1%). No differences were evidenced between people reactivity to polyproteins of the two dirofilarial species, nor differences related to the gender of examinees. Factor risks evidenced were: i) place of residence; ii) spending work time outdoors during the mosquito season; iii) spending time outdoors and nearby rivers, lakes, swamps or canals; unespectedly, iv) cat owning.ConclusionThe findings emerging from this investigation indicate that clinicians and public health authorities should pay greater attention to this zoonosis. Continuing education and training of physicians will greatly contribute to the knowledge of the actual impact of filarial worms on animal and public health, and allow for the planning of suitable measures to prevent the infections.

| INTRODUC TI ONSuperficial fungal infections (SFI) are one of the most common diseases in the world with an exceptionally high prevalence in the range of 22%-25%. 1 The major causative agents of SFI with public and veterinary health relevance are the dermatophytes that infect keratinized tissue (skin, hair and nails) of humans and animals. Pathogenic species in this group are anthropophilic and zoophilic fungi belonging to three genera: Trichophyton, Microsporum and Epidermophyton.Other, clinically less important, dermatophytes are geophilic and zoophilic species divided over Nannizzia, Lophophyton, Arthroderma, Ctenomyces genera and two newly introduced genera, Guarromyces and Paraphyton. 2 Summary Background: Superficial fungal infections (SFI), one of the most prevalent diseases in the world, are infections of keratin-rich structures of human body mostly caused by dermatophytes and yeasts. Objectives: The goal of this study was to determine the possible changes in the epidemiology of SFI on the territory of Southeastern Serbia and to investigate epidemiological characteristics and the influence of SFI on the patient's quality of life. Methods: From 2012 to the end of 2017, samples of 1643 patients (568 males and 1075 females, mean age 40.32 ± 22.44 years) with suspected SFI from Southeastern Serbia were examined using the standard mycological methods. The questionnaires were used to investigate epidemiological characteristics.Results: Superficial fungal infections were diagnosed in 20.5% (n = 336) of patients.In the group of dermatophytes, the most prevalent was Microsporum canis (63.9%, n = 76) followed by Trichophyton mentagrophytes (21.8%, n = 26). Non-albicans Candida species were dominant aetiological agents of superficial candidosis (62.3%).BMI ≥25 kg/m 2 (P = 0.019) was determined as an independent risk factor for SFI.There was a statistically significant difference in the EQVAS score between the groups of patients and the control group (P < 0.001). Conclusions:Results of conducted study indicate that SFI prevalence has not changed in the previous period. However, increase of Candida-SFI prevalence, especially Candida onychomycosis, was established.

We report data on the Toxocara seroprevalence evidenced in 2015 from samples of 40 children and 298 adults of the population living in different areas of Serbia, and on possible association of certain variables with infection. Detection of specific antibodies was performed using an enzyme-linked immunosorbent assay; all ambiguous results and part of the positive and negative sera were further analyzed by confirmatory Western blot test. An overall 23.5% seroprevalence was noticed, which was confirmed in 13.0% of the examined population with no significant difference regarding the age (children = 10.0%; adults = 13.4%) or by country area (East = 18.2%; North = 15.5%, Southeastern = 9.5%; p = 0.005). In contrast, the group of adult women proved more reactive than men (p = 0.001), and subjects both who spend spare time in square/parks (p = 0.041) and with positive onychophagy (p = 0.001) habit turned out more exposed to the infection. Possible reasons of these differences were analyzed, and the medical, veterinary, and economic impact of this soil-transmitted zoonosis were discussed.

The results of this study demonstrate that the common predictive value of several markers is higher than individual predictive value of examined risk factors. Patients with multiple risk factors had higher mortality. Multimarker approach provides an opportunity for better risk stratification in dialysis patients.
