Molecular identification, occurrence, and risk factors for small Babesia species among American Stafford Terriers in Serbia
No full textIn Serbia, Babesia canis is the predominant cause of canine babesiosis, while B. gibsoni and B. vulpes have been reported only sporadically. Limited awareness of these small Babesia species often leads to misdiagnosis and inappropriate treatment. International reports in-dicate that American Staffordshire Terriers (ASTs) and related breeds are particularly af-fected. This study examined 101 ASTs over a two-year period to determine the occurrence of small Babesia species and identify dog- and owner-related risk factors. Collected data included age, sex, body condition score (BCS), clinical signs, presence of scars, history of vector-borne diseases (VBD), living conditions, antiparasitic prophylaxis, and tick expo-sure. Molecular identification using PCR and Sanger sequencing revealed that 37 dogs were positive for Babesia spp.; among them, 36 were infected with B. gibsoni and one with B. vulpes. Significant risk factors associated with infection included the presence of scars, low BCS, history of VBDs, tick exposure, and living in rural areas. These findings demon-strate a notably high occurrence of B. gibsoni and the presence of B. vulpes in ASTs in Ser-bia. The results highlight the need for improved awareness, accurate molecular diagnos-tics, and targeted preventive and therapeutic measures. Additionally, observed risk fac-tors suggest chronic infection and support transmission pathways linked to dog bites and tick exposure
Insects pests of bees and bee products
No full textNumerous insects species are parasitic and cause significant health problems by their action or as vector
of diseases. Insects from the Diptera family are the most important parsites among honey bees. The most
common and well-known insects are members of the genera Senotainia and Braula, family Vespidae (genera
Vespula and Vespa) and family Pyralidae. In addition to them, a large number of insects appear as pests of bees
and bee products, which are primarily pests of plant and animal products. Dermestes lardarius, commonly
known as the larder beetle is a common pest of households and storage facilities. It is a hard wing up to 7.5 mm
in size, black in color, with a wide transverse stripe, which in different stages of development can be found on
the plant in the hive or outside it, and damage to the plant is caused by the larvae that develop in it. In addition
to destroying combs, the larder beetle also transmits the causative agent of nosemosis, the American Fulborn
disease. Apiarius (Trichodes apiarius L.) attacks weak bee colonies. Namely, females lay eggs on the flowers of
plants from which bees bring them together with pollen into the hives. They feed on bees, larvae and pupa
shells that fall to the bottom of the hive. The larvae are parasites of bees (hence the name “apiarius”), as the
adults lay the eggs in the nests of solitary bees (Osmia and Megachile species) or in hives of honey bees, eating
larvae and nymphs. Pollen parasites include various acarinae, such as, for example. Tyroglyphus farinae,
Glyciphagus domesticus, Pericystis alvei. In the hive, there are various tree parasites that are introduced with
pollen and as such feed on honey (Lepidopterae). The commensals also include scorpions, some types of flies
and the wine fly Drosophila funebris. These species are mostly omnivores
Wild mammals as sentinels for West Nile virus circulation : evidence from Serbia
No full textWest Nile fever is a mosquito-borne zoonotic disease caused by West Nile virus (WNV), maintained in an enzootic cycle between avian hosts and Culex mosquitoes. While birds are the principal reservoirs, WNV also infects a wide range of mammals, including humans, horses, and wildlife species. In this study, we assessed WNV seroprevalence in wild ungulates, wild boars, golden jackals, and the invasive rodent nutria in Serbia. A total of 522 serum samples from wild animals were tested. Antibodies against WNV were detected across all tested species, with seroprevalence rates of 37% in wild boars, 11.9% in nutrias, 32.4% in golden jackals, 50.6% in red deer, and 9.1% in roe deer. Detection of antibodies in both adults and juveniles provides evidence of recent transmission during the study period. These findings confirm widespread circulation of WNV in Serbian wildlife and suggest that wild ungulates, carnivores, and invasive rodents may serve as useful sentinel species for monitoring WNV prevalence and geographic spread in natural ecosystems
Tackling cyanobacterial blooms: sustainable solutions for improving water quality and ecosystems
No full textFormer food in animal feed
No full textWith the global population on the rise and growing demand for animal products, competition between food sources for humans and animals is intensifying. As a result, the livestock
industry is actively seeking cost-effective feed alternatives that are not suitable for human
consumption. One promising option is the use of former food products (FFPs), which are
derived from leftovers and residues from food processing. Available FFPs offer a potential
substitute for traditional cereals and concentrates in animal diets. This review examines the
relevant regulatory framework alongside recent findings on the application of FFPs in animal nutrition, focusing on their capacity to replace energy-rich feeds while addressing the
associated risks and benefits. Overall, existing research supports the use of FFPs as a sustainable practice in animal feeding, contributing to global efforts to reduce food wasteThe paper was presented at the 63rd International Meat Industry Conference “Food for Thought: Innovations in Food and Nutrition” ‒ Zlatibor, October 05th-08th 2025.Predavanje po poziv
Pasture seeding - basic agrotechnical measure for revitalization and obtaining quality of pasture
No full textMost of the plants on natural pastures are wild species that have survived in those ecosystems
thanks to various types of adaptations. A large number of these plant species are still relatively
poor food for domestic animals, in terms of quality and quantity. On sown and over-sown
pastures, selected plant species, in interaction with fertilization and proper methods of use, give
significantly more good quality fodder in quantity. During a certain period of use, some of the
sown lawns slowly return to their original state, i.e. there are fewer productive species, so it is
necessary to renew them. On the other hand, the continuous breeding improvement of grass and
leguminous species dictates their introduction into grazing and mowing systems, which
improves the performance of domestic animals, regulates pasture production throughout the
growing season, and restores damage from pests, floods, droughts, and natural die-off. Pasture
sowing should be done in March, April and May, depending on the area. This is an
agrotechnical measure that mainly improves natural grasslands in order to increase yields and
improve the quality of the grass mass. However, reseeding has a wider significance for the repair of degraded grasslands, especially pastures in hilly and mountainous areas to protect the
soil from erosion and improve the environment. Sub sowing is sowing, the sowing of grass and
grass-leguminous mixtures into the existing grass cover, when it has been thinned more or in
some places completely destroyed. In this way, the floristic composition of the lawn is
improved, the better grasses are enhanced and the worse weed plants are suppressed, the density
of the grass cover increases, especially its productivity and quality, the soil is more successfully
protected from erosion and the environment as a whole is improved. It is also important to skip
grazing the first year after seeding
Effects of gallic acid on mineral content in a Drosophila melanogaster model of fragile X syndrome
No full textAlternative animal models such as Drosophila melanogaster are widely used in modelling
genetic disorders such as fragile X syndrome (FXS). Drosophila models of FXS can be used
for initial testing and developing novel potential treatment options. On the other hand, natural
polyphenols such as gallic acid (GA) are attracting significant attention in pharmacological
research due to their remarkable diversity, low toxicity, and a broad range of pharmacological
effects. The aim of the study is to compare macro- and microelement content in Drosophila
model of FXS treated with different concentrations of G
Hemijske karakteristike mehanički separisanog pilećeg mesa i upotreba u proizvodnji
No full textMehanički separisano meso (MSM) je nusproizvod živinarske industrije koji zahteva
rutinsku procenu kvaliteta. Cilj ove studije bio je da se prikažu rezultati praćenja
kvaliteta uzoraka mehanički separisanog pilećeg mesa, koji su prikupljeni u
periodu od dve godine, a proizvedeni od istog proizvođača i uzorkovanih na mesečnom
nivou. Kroz hemijsku analizu sadržaja kalcijuma, masti, proteina, vlage,
ukupnog pepela i sastava masnih kiselina je sprovedena kontrola. Osnovna svrha
pregleda je bila da se ukaže na promenu sastava i fluktuaciju rezultata kada je u
pitanju isti proizvođač, a mehanički separisano meso dobijeno istom tehnologijom
proizvodnje i naravno poreklom od živine sa iste farme. Hemijska analiza je
bila fokusirana na sadržaj osnovnih parametara, odnosno masti, proteina, vlage
i ukupnog pepela, koji su važni za njegovu dalju upotrebu u proizvodnji. Srednja
vrednost dobijenih odnosa masnih kiselina upoređena je sa vrednostima odnosa
masnih kiselina analiziranih u proizvodima, kao što je proizvod mini pileća posebna kobasica, koji u svom sastavu sadrži MSM, ali i sa takozvanom, prerađenom pilećom masnoćom koja se takođe dalje koristi u proizvodnji mnogih proizvoda

Two serious conditions, one sudden loss: mesenteric volvulus and dirofilaria immitis in a dog
No full textSudden death has been thoroughly well defined and investigated in human medicine and its definition is not as rigorously established in veterinary medicine. In this case a 7-year-old German Shepherd was brought to the Small Animals Clinic of the Faculty of Veterinary Medicine at the University of Belgrade in very poor state. Despite treatment, the dog died 15 min after being admitted to the clinic. Since poisoning was suspected, the owners requested an autopsy. The dog was taken to the Department of Forensic Veterinary Medicine, Faculty of Veterinary Medicine, University of Belgrade for necropsy. Pathomorphological examinations revealed rupture of the mesentery with mesenteric volvulus. In addition, a large number of adult forms of Dirofilaria immitis were found in the right atrium, ventricle and in truncus pulmonalis. Further examinations of the respiratory system revealed clusters with partially degraded adult parasites in the lobes. The dog died due to mesenteric volvulus which was a rare finding, with an even rarer finding that was lung nodules with adult D. immitis parasites
The influence of sample quality and ELISA kits on the occurrence of single reactors in serological diagnostics of foot-and-mouth disease and peste des petits ruminants
No full textRegular monitoring of susceptible animal species for specific antibodies is essential to achieve or to maintain diseasefree
status for a country. The absence of certain disease in a country for many decades would yield expectation that collected
animal serums would be negative for the presence of specific antibodies. However, large-scale tests often dismiss singlereactor
findings as poor sample quality. The current study aimed to investigate the effect of storage conditions of negative
serum samples and the specificity of ELISA kits on the test results, focusing on two key livestock diseases: foot-and-mouth
disease (FMD) and peste des petits ruminants (PPR). Serum samples from bovine and ovine sources were stored at varying
temperatures and durations, were subjected to freeze-thaw cycles, and were retested. Results were compared with zero-day
tests which were considered to be truly accurate and negative. The quality of ELISA test results is less significantly affected
by serum samples quality (affected by temperature, storage time, and freeze-thaw cycles) and occurrence of false positive
single reactors, than the diagnostic specificity of different ELISA lots. This study challenges the conventional justification
for single-reactor findings and underscores the importance of ELISA kit quality
