The worldwide problem of infectious diseases has appeared in recent years, and antimicrobial agents are crucial in reducing disease emergence. Nevertheless, the development and distribution of multidrug-resistant (MDR) strains in pathogenic bacteria, such as Escherichia coli, Staphylococcus aureus, Salmonella Typhi and Citrobacter koseri, has become a major society health hazard. Essential oils could serve as a promising tool as a natural drug in fighting the problem with these bacteria. The current study aimed to investigate the antimicrobial effectiveness of tea tree (Melaleuca alternifolia (Maiden and Betche) Cheel), rosemary (Rosmarinus officinalis L.), eucalyptus (Eucalyptus obliqua L’Hér.), and lavender (Lavandula angustifolia Mill) essential oils. The antimicrobial properties of essential oils were screened against four pathogenic bacteria, E. coli, S. aureus, S. Tyhpi, and C. koseri, and two reference bacterial strains, while for the testing, the agar well diffusion method was used. Gas chromatography (GC) and gas chromatography–mass spectrometric (GC–MSD) analyses were performed on essential oils. The obtained results showed that M. alternifolia essential oil is the richest in terpinen-4-ol, R. officinalis and E. oblique essential oils in 1,8-cineole, and L. angustifolia essential oil in α-terpinyl acetate. In addition, the main bioactive compounds present in the essential oil of tea tree are rich in α-pinene (18.38%), limonene (7.55%) and γ-terpinene (14.01%). The essential oil of rosemary is rich in α-pinene (8.38%) and limonene (11.86%); eucalyptus essential oil has significant concentrations of α-pinene (12.60%), p-cymene (3.24%), limonene (3.87%), and γ-terpinene (7.37%), while the essential oil of lavender is rich in linalool (10.71%), linalool acetate (9.60%), α-terpinyl acetate (10.93%), and carbitol (13.05%) bioactive compounds, respectively. The obtained results from the in vitro study revealed that most of the essential oils exhibited antimicrobial properties. Among the tested essential oils, tea tree was discovered to demonstrate the strongest antimicrobial activity. The recorded MIC of S. Typhi was 6.2 mg/mL, 3.4 mg/mL of C. koseri, 3.1 mg/mL of E. coli, and 2.7 mg/mL of E. coli ATCC 25922, compared to M. alternifolia. Similarly, only S. aureus ATCC 25923 showed antimicrobial activity towards R. officinalis (1.4 mg/mL), E. oblique (2.9 mg/mL), and L. angustifolia (2.1 mg/mL). Based on the obtained results, it is possible to conclude that tea tree essential oil might be used as an ecological antimicrobial in treating infectious diseases caused by the tested pathogens.

The aim of this research was the visual characterization and investigating the effects of Alternaria spp. contaminated wheat grains in the starter stage of broilers nutrition on productive parameters and oxidative stress. The research was divided into two phases. Bunches of wheat in post-harvest period of year 2020 was collected from a various locality in Serbia and Albania. In the first phase, collected samples were visual characterized by Alternaria spp. presence by color measurement methods. Gained results are conferred in the range of the color properties of grain color properties of Alternaria toxins. Wheat grain samples were significantly different (p < 0.05) in terms of all measured color parameters (L*, a*, b*). Classification of field fungi in analyzed wheat grain samples showed that the significant field fungi were Rhizopus spp., followed by Alternaria spp., and Fusarium spp. In the second phase, biological tests with chickens were carried out during the broiler chickens’ dietary starter period in the first 14th days of age. At the beginning of the experiment, a total of 180-day-old Ross 308 strain broilers were equally distributed into three dietary treatments, with four replicates each. Dietary treatments in the experiments were as follows: basal diet without visual contamination of Alternaria spp. with 25% wheat (A1), a basal diet with visual contamination of Alternaria spp. with 25% wheat from Serbia (A2), basal diet with visual contamination of Alternaria spp. with 25% wheat from Albania (A3). The trial with chickens lasted for 14 days. After the first experimental week, wheat infected with Alternaria spp. in treatment A2 and A3 expressed adverse effects. The highest body weight of chickens of 140.40 g was recorded in broilers on control treatment A1 with statistically significant differences (p < 0.05) compared to treatments A2 (137.32 g) and A3 (135.35 g). At the end of the second week of test period, a statistically significant (p < 0.05) difference in body weight of broiler chickens could be noticed. The highest body weight of 352.68 g was recorded in control treatment A1, with statistically significant differences compared to other Alternaria spp. treatments. The lowest body weight of chickens was recorded in treatment A3 (335.93 g). Results of feed consumption and feed conversion ratio showed some numerical differences between treatments but without any statistically significant differences (p > 0.05). Alternaria spp. contaminated diet increased glutathione (GSH), glutathione reductase (GR), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) and decreased peroxidase (POD) and superoxide dismutase (SOD) serum levels, respectively. Built on the achieved results, it can be concluded that the wheat contaminated with Alternaria spp. in broilers nutrition negatively affected growth, decreased oxidative protection and interrupted chicken welfare in the first period of life.

The organic food is progressively enticing purchasers’ attention, as it is recognized to be better than the food produced by the conventional agriculture and more sustainable for the natural environment. Pesticides and their metabolites can enter the human body via food and water. In the food production, over 60 thousand chemical agents are applied, while 90% of the harmful substances are consumed. The organic production is based on the qualitative and healthy food using the natural resources in an ecologically sustainable way. The European Regulations set the maximum pesticide levels (MRLs) in the organic products, which are also regulated by The United States Department of Agriculture in their National program supported by The United States Environmental Protection Agency. It is imperative to bear in mind that in the products from the organic production, the multiple detections cannot be tolerated, i.e., that one product cannot contain more than two detected pesticide residues. In this paper, a multi-residue pesticide method has been developed to determine the pesticides in the agricultural products from the organic and conventional production. In this work, 60 pesticides were analyzed using a simple QuEChERS sample preparation procedure, followed by LC-MS/MS. The tomato, potato, apple, and carrot samples from the organic and conventional products were collected from the market and the pesticide residues assessment comparing the organic to the conventional was done.

Inadequate choice and application of control measures for agricultural pests, ectoparasites of livestock and domestic animals, vectors and reservoirs of various diseases of human medicine and veterinary importance in urban areas has caused the resistance occurrence and cross-resistance in a large number of arthropods. Their control is becoming increasingly difficult and challenging. For example, the use of acaricides is indispensable in the control of European red mite (Panonychus ulmi, Acari: Tetranychide), but also for other species from this family that are all significant pests in agricultural production, horticulture and forestry. The resistance occurrence and maintenance and cross-resistance in arthropods is a global phenomenon. The aim of this paper was to present the resistance factors and mechanisms in Panonychus ulmi control and to list the active substances for which there was an evidence that resistance has been acquired, all with the goal of pointing out the problem of resistance in this species and highlight the ways to prevent it. The occurrence and evolution of resistant arthropod populations could have multiple consequences that can be observed from an agricultural, economic, health, and environmental perspective.

This paper evaluates the occurrence of the TAs in 71 food products samples. The analysis comprised the following samples: 18 corn puffs, 12 popcorn, 16 corn and 25 corn grits samples, obtained from the shops in Belgrade and Novi Sad during 2019. and 2020. The overall number of the samples with the atropine and scopolamine detections below the LOQ was 61,97%. The percentage of the detection of the tropane alkaloids above the limit of quantification, which may have a negative effect on the health of humans and animals, was 29,57%. The atropine and scopolamine detections are equal in the number of corn puffs, popcorn and corn samples, while 7 samples of corn grits contained the atropine, and 6 of them contained the scopolamine. The highest mean concentrations of the atropine and scopolamine were detected in corn grits, followed by popcorn, then in the corn, while the lowest were in the corn puffs.

The food of animal origin that is the most consumed is the table egg, but laying hens treated with antibiotics can produce eggs contaminated with antibiotic residues. Residues of antibiotics may present a risk for consumer health. Keeping in mind that laying hens almost always suffer from Mycoplasma (Mycoplasma synoviae), for which they are treated with antibiotics, high-quality egg production is even harder. Our research aimed to investigate the influence of three different antibiotics compared to the tea tree (Melaleuca alternifolia) essential oil administered to naturally infected laying hens with M. synoviae, on antibiotic residues in eggs as well as the egg nutritive and sensory qualities. A total of 20,000 laying hens, housed in one facility and divided into four lines each consisting of 5000 hens naturally infected with M. synoviae, was used. For the antimicrobial therapy, tetracycline (TC), oxytetracycline (OTC) and chlortetracycline (CTC) were used, respectively. As a control, tea tree essential oil (TT) was used. Based on the gained results all tetracyclines treatment residue values were significantly (p < 0.05) higher compared to the control treatment (TT), but without any significant differences (p > 0.05) between themselves. The results showed no differences in the nutritive and the sensory qualities of eggs between the control and the experimental treatments (p > 0.05). Keeping in mind the obtained results from this study, it can be concluded that tea tree essential oil could be successfully used as a natural antibiotic in the treatment of M. synoviae, without any adverse effects on table egg quality.

The level of production in a variety of organic production systems is often lower than in other traditional production systems. In poultry production, there is also a direct negative effect of the small scale regarding sustainable organic poultry production. Regardless of differences between organic and conventional production systems, this experiment aimed to investigate the usage of tea tree Melaleuca alternifolia (Maiden and Betche) Cheel essential oils as a natural alternative to antibiotics in hen nutrition on productive parameters, table egg quality and eggs fatty acid profile as a promising sustainable organic agricultural tool. A total of 360 Lohmann Brown hens, aged 54 weeks, divided into three different treatment diets, were supplemented with 0 (T1), 40 (T2) and 80 mg/kg (T3) of M. alternifolia essential oil, respectively. Experimental treatments were replicated four times within 30 birds each. The experiment lasted for a total of 56 days (55 to 62 weeks of hens age). A 56-day experimental had two timetable periods of 28 days each: period 1 (55 to 58 weeks of hen age) and period 2 (59 to 62 weeks of hen age). For compound feed supplemented with M. alternifolia essential oil, daily egg production and the efficiency of nutrient utilization (FCR) was improved significantly (p < 0.05) until the end of week 58, with a significant (p < 0.05) increase in the thickness of eggshell, as well as egg production (p < 0.05). However, egg mass, feed consumption, FCR and albumen height, Haugh unit, and eggshell strength did not show any significant (p > 0.05) differences influenced by essential oil feed supplementation. Lower concentrations of saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA), and higher concentrations of polyunsaturated fatty acid (PUFA), were recorded with M. alternifolia essential oil supplementation, but without significant (p > 0.05) differences. At the end of the experiment, the obtained results showed that the addition of M. alternifolia essential oil to hen nutrition had a positive effect on production parameters and eggs fatty acid profile, with increased eggshell thickness (p < 0.05).

Continental inland saline wetlands are among the most endangered habitats in Europe. In the Danube-Tisza-Danube canal network (Serbia, Southeastern Europe), which is one of the largest canal networks on the continent, the rare and endangered inland saline wetland Bolboschoenus maritimus community (BMC) has been found at only two locations. Two vegetation types of the community have been identified: (i) with Bolboschoenus maritimus and Marsilea quadrifolia (BMC-M) dominance and (ii) with Bolboschoenus maritimus and Butomus umbellatus (BMC-B) dominance. The aim of the study was to compare the habitats of the ascertained vegetation types in terms of 55 water and soil properties that influence their development, floristic composition and differentiation. The main properties influencing the community development and differentiation were water alkalinity, chemical oxygen demand, CO32−, water pH, soil conductivity, K+ and Ca2+ content in the soil. Both vegetation types grow in non-saline, slightly alkaline, nutrient-rich habitats with eutrophic water. When compared to BMC-B, BMC-M was found on heavy clay soils with higher conductivity, CaCO3, humus, nutrients, macroelements, and Na+ content, in shallower water with higher suspended solids and oxygen content, lower contents of nutrients, dissolved salts, HCO3−, macroelements, conductivity, and alkalinity. The study provides new data on the BMC distribution in this part of Europe and the first detailed information on its habitat conditions. Thirty-one species from the European Red List of Threatened Species were found in the stands. These results may be useful when deciding on the appropriate preservation measures aimed to rehabilitate other wetland habitats and biodiversity.

Bisphenol A is a monomer used primarily in the production of polycarbonate plastics and epoxy resins. Polycarbonate plastic is used in a wide variety of digital media products, electrical and electronic equipment, sport safety equipment, reusable food and drink containers, etc. Epoxy resins are used in engineering applications, paints and adhesives and also in a variety of protective coatings in metal cans for foods, bottle tops and water supply pipes. The content of BPA was evaluated in 16 samples (6 baby bottles and 10 drinking containers - can) collected during 2018/2019, of which three baby bottles and 8 cans were collected in 2018, while three baby bottles and 2 cans in 2019. A simple HPLC-FLD analytical method was validated for the quantitation of BPA from baby feeding bottles and cans. The separation was performed on a C18 column. Good linearity was obtained over the concentration range of 0.3-6.0 ?g/mL with the regression coefficient (R2) of 0.9998. The limit of detection (LOD) and limit of quantification (LOQ) were 0.01 and 0.03 ?g/mL, respectively. The repeatability of the method (%RSD) was between 4 and 6%, while the recovery ranged from 104.3 to 109.7%. The extraction of BPA was done in accordance with SRPS EN 13130-1:2008. The methods were applied to determine BPA release from baby bottles, performing repeated procedures according to EU and national regulations (SRPS CEN/TS 13130-13 (2008)). The conformity was evaluated according to National and EU requirements. The results show that Bisphenol-A was not detectable in any of the analysed samples.

This study was conducted in order to assess the effect of inoculation of soybean (Glycine max L.) seeds with Trichoderma asperellum, followed by mites (Tetranychus urticae) exposure on lipid peroxidation (LP) process and the activity of antioxidant enzymes. T. urticae is an occasional pest of soybean that causes biotic stress. Biotic stress leads to overproduction of reactive oxygen species (ROS) which may cause damage to vital biomolecules. Enzymatic antioxidant defense systems protect plants against oxidative stress. T. asperellum is commonly used as biocontrol agent against plant pathogens. It has been suggested that previous inoculation of seeds with T. asperellum may cause induced resistance against biotic stress. The aim of this study was to determine LP intensity and antioxidant enzymes activity in inoculated and non-inoculated soybean seedlings with and without exposure to mites. Noticeably higher LP intensity was detected in non-inoculated group treated with mites compared to control group. Inoculated soybean seedlings treated with mites had lower LP intensity compared to noninoculated group. Also, it has been noticed that inoculation with Trichoderma asperellum itself, produced mild stress in plants. In addition, positive correlation between enzymes activity and LP was noticed. The level of oxidative stress in plants was followed by the change of LP intensity. According to results obtained, it was concluded that the greatest oxidative stress occurred in non-inoculated group treated with mites and that inoculation successfully reduced oxidative stress. The results indicate that inoculation of soybean seeds with T. asperellum improves resistance of soybean seedlings against mites attack.

In Europe, of all the vector transmitted diseases, the occurrence of lyme disease is the one most often registered, and the most significant vector Borrelia burgdorferi is the tick Ixodes ricinus. Both humans and animals contract lyme disease. The risk of the occurrence of lyme disease is in correlation with potential exposure to tick bites and depends on the density of the tick population in the endemic area, the percentage of ticks infected with the cause of lyme disease, the duration and the nature of the activity of the susceptible population in a certain area. The objective of these investigations was to determine the entomological and the ecological risk index, as well as to assess the risk of transmission of the cause of lyme disease in the territory of Vojvodina Province in the Republic of Serbia. Ticks were collected at 12 locations in the South Backa District of Vojvodina. A total of 1400 ticks were identified up to the level of species. After establishing the infection of ticks with the cause of lyme disease, the entomological and the ecological index was determined for the given regions using microscopic examination in a dark field. Two species of ticks aere identified in this geographic region (Ixodes ricinus and Dermacentor marginatus). Examining I. ricinus, the prevalence of infection B. burgdorferi was established, ranging up to 33.1%. The ecological risk index indicates that there is a potential risk of humans and animals becoming infected at 8 localities. It was determined for 3 localities that there is a definite actual risk of the transferrence of causes of lyme disease.

Species composition and population dynamics of spider mites (Panonychus ulmi (Acari: Tetranychidae) (Koch) and Tetranychus urticae Koch (Acari: Tetranychidae)) and predaceous mites (Amblyseius andersoni (Chant) (Acari: Phytoseiidae) and Zetzellia mali (Ewing) (Acari: Stigmaeidae)) were studied for eight months each year (March–October) during 2005–2007 at two localities with different intensities of pesticide use. Using Berger–Parker's dominance index and Sorenson's coefficient, the index of dominance and predator–predator, predator–prey, and prey–prey associations were defined among each of these species to determine changes in species compositions and population densities and comprehend the influence of pesticide use in pest management on populations of spider and predatory mites in apple orchards. Sorenson's coefficient helped to measure the intensity of positive, neutral, or negative interspecific associations for each species and Berger–Parker's dominance index clarified the dominance of specific species. During 2005 the dominant species in both localities was P. ulmi, but during 2006–2007 at one locality both species of spider mites showed almost equal dominance. The results of Sorenson's coefficient confirmed that there was significant predator–prey association among P. ulmi and A. andersoni and P. ulmi and Z. mali, and prey–prey association between P. ulmi and T. urticae in both localities. The analysis of the population dynamics showed delayed occurrence of predatory mites compared with the spider mites, from 48 to 106 days for A. andersoni and 91 to 137 days for Z. mali depending on the research period and locality.
