Gastrointestinal nematodes (GINs) nowadays present a serious threat to sustainable sheep breeding. Various classes of commercial anthelmintics were used to control these parasites. However, due to the development of anthelmintic resistance (AR), the efficacy of these drugs has decreased, which in turn resulted in high economic losses. For thes...

Herbal products such as essential oils may play a promising role in the treatment of infections caused by gastrointestinal nematodes (GINs). The aim of this study was to evaluate the in vitro potential of 11 essential oils (EOs) and one binary combination of isolated EO compounds, as well as the in vivo anthelmintic efficacy of two EO formulations....

For the living world, in the existing ecosystem, for the reproduction, production and spread of plant species, bees are one of the most important parts of nature. In the pollination of certain field and fruit-vegetable plant species, bees participate with almost 100%. Any factor that contributes to reducing the presence of bees in nature, directly...

Nosemosis is a bee disease practically present in all countries of the world. Control of the presence of Nosema apis and Nosema ceranae is of great importance. The consequences for bees will depend on the degree of infection of the bees colony.Weakening of bee colonies, reduction of production possibilities, contamination with bee feces of hives, d...

The development of resistance to commercial anthelmintics, particularly in different species of gastrointestinal nematodes (GINs), requires the search for alternatives. Within that context, the aim of this study was to evaluate the in vitro ovicidal activity of five different essential oils (EOs): Origanum vulgare, Satureja hortensis, Thymus vulgar...

The pig production is considered to be amongst the animal husbandry sectors with the highest antimicrobial usage. In Serbia, antimicrobials have wide application at pig farms as therapeutic but also as a prophylactic treatment. The aim of the research study was assessment of the antimicrobial usage in different stages of pig production in commercia...

The economic losses caused by gastrointestinal nematodes of small ruminants are increasing today due to the development of anthelmintic resistance. Therefore, researchers from different parts of the world are searching for new, alternative strategies to control these parasites. As a valuable natural resource, medicinal plants and their products hav...

Modern livestock production inevitably involves the use of antimicrobial drugs. Adequate application thereof depends on the application of appropriate biosafety measures as well as timely and accurate diagnostics of the diseases. Administration of antimicrobial drugs without previous identification of “zootechnical errors” or relevant laboratory an...

Background: Dirofilaria immitis is vector borne parasite of carnivores, with zoonotic potential, endemic in many parts of the world, including Europe. The aim of this study was to determine the prevalence of Dirofilaria immitis infection in dogs from shelters, especially compared to their lifestyle. Dogs living in shelters in Serbia may be at high...

Leishmaniosis is a zoonotic disease caused by Leishmania spp. Serbia was an endemic region for this disease until the second half of the 20th century. Nowadays, canine leishmaniosis appears to be a re-emerging vector-borne disease in Serbia. Its spread is enabled by the presence of Phlebotomus spp. sandflies in this region. The objective of this st...

Cardiopulmonary dirofilariosis in dogs and other carnivores is caused by Dirofilaria immitis, while Dirofilaria repens usually causes a subcutaneous infection. The importance of red foxes and golden jackals in the epidemiology of dirofilariosis remains unknown. Thus, the aim of this study was to conduct a cross-sectional molecular survey of Dirofil...

Ovine brucellosis can cause epididymitis and reduce fertility in rams and therefore is an important disease in sheep and rams from economic point of view. Sometimes it causes abortions and increased perinatal mortality in sheep as well, but it primarily affects male animals. Brucella ovis was first identified in northern region of Serbia, in 2008-2...

Dermanyssus gallinae or the poultry red mite is currently the most im-portant ectoparasite aff ecting egg-laying hens in several countries causing reduced poultry welfare, mortality and even allergic reactions in poultry farms workers. Its short life cycle, which in optimal conditions can be com-pleted within 7 days, and ability to survive in extre...

The aim of our study was to determine whether and to what extent certain species of helminths and protozoa are present in the wild boar population living in hunting grounds in Vojvodina. For this purpose, 52 faecal samples of hunted wild boars (aged 6 months to 2 years) were examined. Examination of the faeces was performed using classical coprosco...

The quality of drinking water depends on the water sources, but also on the quality of the water distribution system which supplies the water on to the final user. In addition, the possibility of contamination of water used for watering animals in the farm buildings depends on the hygienic conditions on farms. Microbiological quality of water on fa...

Diagnostics of the uterus and fertility control include clinical, bacteriological, cytological and histopathological examinations. Bacteriological studies should be accompanied by cytological and pathological tests, because the presence of inflammatory processes is the most important for diagnosis and prognosis. Although, there is no standard metho...

Skin lesions caused by dermatophytes are classified depending on the infected skin structure: surface layer of cutis, fur layer, clutches or nails. Surface mycoses are caused by dermatophytes: Epidermophyton, Microsporum and Trichophyton species (also important are Malassezia spp., Candida spp., and Trichosporon). Skin is the target tissue for fung...

Mycotoxins are secondary metabolites of fungi that can contaminate animal feeds at all stages of food production chain. Consumption of feed contaminated with mycotoxins may result in immunosuppression, which represents a predisposing factor for occurence of infectious diseases in livestock. The influence on immune system is of special interest in s...

In our country a certain number of wild boars is controlled and reared on enclosed hunting ground, while a number of free-ranging population is mainly unknown. The control of health status of wild boar population is quite demanding and it is not easy to achieve. Also, often is not possible entirely to perform a complete diagnostic examination in wi...
