Strongyloidiases are caused by nematodes of the suborder Strongylida and are the most widely prevalent group of gastrointestinal helminthiases of sheep in many regions of the world. Among gastrointestinal strongylids, the helminths of the genus Nematodirus are represented by the largest number of species and highest infection rates in sheep. Nematodirosis causes significant economic losses in the sheep industry through decreased sheep productivity, delayed growth and development of young animals, and a reduced resistance to other diseases. Timely and accurate diagnosis of nematodirosis and identification of the pathogen will effectively prevent the disease and help to carry out treatment and prevention measures. Therefore, the aim of the work was to study the definitive morphometric characters of mature males and females of Nematodirus spathiger Railliet, 1896, obtained from the small intestine of domestic sheep. The results of experimental studies showed that nematodes of this species morphologically are characterized by a thin filiform body, a vesicle at the head end and a chitinous tooth in a short oral capsule. The differential morphological features of male nematodes of N. spathiger include specifics of the structure of spicules, their distal end and the shape and location of the rays of the caudal bursa; in females, those are the features of the structure of the vulva and tail end. In identification of male nematodes of N. spathiger, it is proposed to use 40 metric parameters, of which 11 characterize the overall size of the body, esophagus and vesicles, 24 refer to the size of the tail bursa, 5 to the size of the spicules and the enveloping membrane. To help identify the females of N. spathiger, 25 parameters are chosen, of which 14 also characterize the overall size of the body, esophagus and head vesicle, 6 refer to the size of the cuticular formations of the vulva and its location, and 5 to the size of the tail end, the location of the anus and the size of the tail spike.

Significant economic losses to poultry farms are caused by infectious, especially viral diseases, including infectious avian encephalomyelitis (IAE). A possible threat to the profitability of the poultry industry in Ukraine at present is the epizootic disadvantage of poultry infectious encephalomyelitis. Economic losses from IAE include losses from increased poultry death, reduced productivity, hatchability of chickens, additional costs for disease prevention and elimination. Quick and effective diagnosis of the disease, in this case, makes it possible to predict the development of the epizootic process, assess possible economic losses, timely and correctly develop a plan of treatment and prevention measures. Permanent immunity is formed after the disease (again, the poultry is usually not sick), as well as during vaccination. The only effective method of IAE prevention is preventive vaccination of parent flocks and laying hens with live vaccine before laying eggs (in immune herds of laying hens, the virus is not transmitted vertically). In Ukraine, live - mono and combined vaccines have been registered for the specific prevention of IAE, including: mono- vaccines - 5 (45.4 %) and combined - 6 (54.6 %). During selective serological monitoring of blood sera of poultry eggs from some poultry farms of Ukraine for the presence of antibodies to the IAE virus of poultry, different levels of average titers were found. In total, the blood sera of laying hens from 34 batches from 15 poultry farms were tested for the presence of medium antibodies to the IAE virus. Medium antibody titers in poultry that were vaccinated with live IEM vaccines once at the age of 62-70 days ranged from 999 to 12785. Below the baseline, medium titers were found in 2 batches, namely among birds aged 13 and 22 weeks. When determining the effectiveness of the vaccine VIR 110, Biovak (Israel), which was used on 29 batches of laying hens, it was found that the average titers to IAE virus ranged from 222 to 10520. Moreover, the average titers of antibodies to IAE were below baseline (from 5000 - 12,000) among birds of 3 batches at 13, 15, and 45 weeks of age, which is 10.3 %. The effectiveness of the vaccine VIR 110 (Biovac) against IAE was 89,7 %. Continuous serological monitoring is necessary to monitor the effectiveness of IAE vaccinations and the epizootic welfare of poultry.

Passalurus ambiguus (Nematoda, Oxyuroidae) is one of the most common parasites of digestive tract of domestic and wild rabbits and rodents. Passalurus spp. are cosmopolitan, and the mature nematodes are localized in the appendages and large intestine of animals. The passaluariasis infections remain quite relevant in modern rabbit breeding, because the disease is highly contagious, with the possibility of unlimited spread inducing significant economic losses. The aim of the study was to determine the identifying morphological species characteristics of P. ambiguus nematodes, which were isolated from the colon of domestic rabbits (Oryctolagus cuniculus domesticus). The identifying characters of Passalurus include morphological features, namely the presence of a spherical bulb in the esophagus, and the presence of three teeth in the oral capsule. Males of P. ambiguus have a characteristic structure of the tail end, namely the presence of papillary protrusions and a massive narrowed part with a spicule handle, and five papillae around the cloaca. Twenty-eight metric indicators are proposed that characterize the size of the body, oral capsule, esophagus in different parts of it, the tail end, spicules, the location of the cloaca. Two different morphotypes of mature females of P. ambiguus were revealed – short-tailed and long-tailed, which were larger by 19 indicators (by 3.2–43.6%). The morphotypes of P. ambiguus females are characterized; the length of the tail, body length and width in different areas, depth of the oral capsule, esophageal size and its structural elements, the location of the vulva and nerve ring, the width of the caudal process. At the same time, the parameters of esophageal bulb length and caudal process in short-tailed females were higher (by 13.9% and 11.9%, respectively) than in the long-tailed females. A total of 25 morphometric parameters were proposed for the identification of P. ambiguus females. The obtained data indicate the feasibility of further research on the causes of occurrence of such morphotypes in P. ambiguus females and the need to take into account the existence of such forms of females for their differential diagnosis taking into account their proposed morphometric parameters.

Nematodoses of the sheep’s digestive tract is distributed both in Ukraine and abroad. Pathogens of these diseases in the form of monoinvasions, as well as associative with other invasive diseases, cause sheep farms considerable economic losses. Systematic monitoring studies that are carried out to establish a helminthofauna specific to a particular region are a key to successful control of parasitic diseases. Information on the species composition of pathogens causing invasive diseases in animals in the territory of a certain region, allows us to conduct scientifically based selection of drugs and to conduct effective, cost-based treatment and prevention measures. Therefore, the purpose of our research was to establish the distribution of nematodoses of the digestive canal of sheep and their peculiarities in the conditions of sheep farms in the territory of the Kyiv region (Central region of Ukraine). The research was conducted in conditions of sheep farms in the Kyiv region (Baryshivka, Bila Tserkva, Zghurivka, Pereiaslav-Khmelnytskyi, Skvyra, Tarashcha, Fastiv and Yahotyn districts). Helminthoscopy of fecal samples was performed using the McMaster’s method. As a result of scatoscopy diagnostics of sheep, a considerable distribution of nematodoses of the digestive canal was established on the territory of the Kyiv region (the severity of the invasion was 48.79 %). According to the morphological features of eggs isolated from faeces of sick animals, parasitization of nematodes from three sequences was established: Strongylata (38.98 %), Trichocephalata (33.36 %), and Rhabditata (27.66 %). It was registered that the sheep farming of the Bila Tserkva, Yahotyn and Zghurivka districts (EI – 61.49, 59.73 and 54.17 % respectively) were the most unfavorable for nematodoses of the digestive tract. The disease was registered in the form of both mono- and mixinvasions. The associative course of diseases (75.03 % of the total number of diseased animals) was dominant with two-, three-, four-, and five-component associations of sheep parasite pathogens (47.63, 35.47, 11.50 and 5.40 % in accordance). It has been established that nematodoses of the digestive canal of sheep (strongylates of the digestive canal, strongyloides and trichiuruses) are in the composition of mixinvasions, the sympathizers of which are: eimeries, moniezies, and melofagoses in various combinations. Key words: nematodoses, strongylatoses of the digestive canal, trichiuruses, strongyloides, scatoscopy research.

The objective: determination of the effectiveness of prevention and medicinal correction of placental dysfunction in pregnant women with chronic salpingo-oophoritis.Materials and methods. The study included 100 pregnant women (basic group) with chronic salpingo-oophoritis, of these, I group (50 women) included patients who received proposed treatment and prevention approach, II group (50 women) received a common set of treatment and prevention measures. The proposed treatment-and-prophylactic approach included prophylactic administration to pregnant women with chronic salpingo-oophoritis from the 8th to the 10th and from the 16th to the 18th week inclusive of natural micronized progesterone at a dose of 100 mg intravaginally twice a day for two weeks. Venotonik and angioprotector were prescribed prophylactically at dose 600 mg from 18 weeks to 37-38 weeks of pregnancy. For therapeutic purposes (blood flow disorders in the uterine arteries and vessels of the umbilical cord that are determined by Doppler), the drug was prescribed at dose 600 mg twice a day for 3–4 weeks.Results. A lower frequency of obstetric and perinatal complications was found in the women in I group than in the patients in the II group. Thus, the rate of placental dysfunction was 6.0±3.36% vs. 34.0±6.7%, respectively, oligohydramnios – 6.0±3.36% and 12.0±4.59%, polyhydramnios – 10.0±4.24% and 22.0±5.86%, fetal distress during childbirth – 6.0±3.36% and 14.0±4.91%, cesarean section – 12.0±4.6% and 24.0±4.27%. In the group of patients with treatment-and-prophylactic approach, the mean of the body weight of newborns was 3486.7±312.71 g, and in women who received a common set of treatment-and-prophylactic measures – 3099.8±295.69 g. The mean of the assessment of the condition of newborns by the Apgar scale at the 1st minute – 7.92±1.54 and 6.81±1.16 points, respectively.Conclusions. The use of micronized natural progesterone and the drug diosmin 600 mg in pregnant women with a history of chronic salpingo-oophoritis reduces the rate of obstetric and perinatal complications during pregnancy.

Intensity Of Invasion

One of the reasons that reduce the efficiency of sheep breeding development and lead to significant economic losses of the industry in Ukraine and the world is helminthic diseases, particularly strongyloidiasis caused by parasitic nematodes. Strongyloides parasitize in the small intestine of animals and lead to slow growth and development of young sheep, diarrhea, anemia, ataxia. At the high intensity of invasion - animals can die. The study aimed to analyze monitoring studies on the prevalence of strongyloidiasis in sheep in Ukraine based on statistical data of the reporting documentation of the State Research Institute for Laboratory Diagnostics and Veterinary Sanitary Examination during 2016–2020. Studies have shown that helminthiasis of sheep is a common invasion in farms of various forms of ownership in Ukraine, where the extent of the invasion ranged from 1.44 to 3.27 %. The share of helminthiasis of the digestive tract of sheep from the total number of detected helminthiasis reaches 84.21 %. The most common of the helminthiases of the gastrointestinal tract were nematodes; their share was 63.07 %. Trematodes and cestodes were diagnosed less frequently; their share among helminthiases of the digestive tract was 35.05 and 1.88 %, respectively. It was found that among the nematodes of the digestive tract parasitizing in sheep in Ukraine, the largest share was strongylidosis, in particular bunostomosis, nematodyrosis, hemonchosis (65.20 %), and strongyloidiasis (33.92 %). A smaller proportion were esophagostomosis (0.74 %) and trichurosis (0.14 %). Indicators of prevalence were: for strongylidosis (bunostomosis, nematodyrosis, hemonchosis) – 10.98 %, for strogiloidiasis – 4.48 %, for esophagostomosis – 0.42 %, for trichurosis – 0.21 %. In terms of years, the rates of damage to sheep by the causative agent of strongyloidiasis fluctuated significantly with the increasing prevalence of strongyloidiasis invasion during 2019–2020. Indicators of infestation of sheep with the causative agent of strongyloidiasis during the study period in Ukraine were at the level of 1.91 % (2018) to 16.14 % (2019). The data we obtained testify to the urgency of the problem of nematodes, particularly strongyloidiasis of sheep in Ukrainian farms, and lead to more thorough research on epizootological, biological features of the causative agent strongyloidiasis and the introduction of effective treatment and prevention measures.

Abstract We study size-at-age and sexual variability of morphometric characteristics of the marsh frog. According to the size of the body, males were divided into three size-age groups (juvenis, subadultus, adultus), females — into four groups (juvenis, subadultus, adultus, adultus-I). We found that the chronological age of frogs (skeletochronology) does not always correspond to their biological age (size and proportions of the body). We noted that the semi-adult males are reliably larger than females by mean values of 26 studied morphometric characters. Males and females of “adultus” group do not differ by linear body size, significant differences were found in body proportions (7 characters). For the females of “adultus-I” group, the mean values of 26 characters are significantly larger than for “adultus” males. The results of our study showed that with the age of the marsh frog, the level of exhibition, directionality and structure of morphometric sex differences changes.

The use of Antiretroviral drugs in treating HIV/ AIDS patients has enormously increased their life spans with serious disadvantages. The virus infection still remains a public health problem worldwide with no cure and vaccine for the viral agent until now. The use of nanoparticles (NPs) for the treatment and prevention of HIV/AIDS is an emerging technology of the 21st century. NPs are solid and colloid particles with 10 nm to <1000 nm size range; although, less than 200 nm is the recommended size for nanomedical usage. There are NPs with therapeutic capabilities such as liposomes, micelles, dendrimers and nanocapsules. The particle enters the body mainly via oral intake, direct injection and inhalation. It has been proven to have potentials of advancing the prevention and treatment of the viral agent. Certain NPs have been shown to have selftherapeutic activity for the virus in vitro. Strategies that are novel are emerging which can be used to improve nanotechnology, such as genetic treatment and immunotherapy. In this review, nanoparticles, the types and its characteristics in drug delivery were discussed. The light was furthermore shed on its implications in the prevention and treatment of HIV/AIDS.

: The current treatment and prevention of oral disorders follow a very sectoral control and procedures considering mouth and its structures as system completely independent from the rest of the body. The main therapeutic approach is carried out on just to keep the levels of oral bacteria and hygiene in an acceptable range compatible with one-way vision of oral-mouth health completely separated from a systemic microbial homeostasis (eubiosis vs dysbiosis). This can negatively impact on the diagnosis of more complex systemic disease and its progression. Dysbiosis is consequence of oral and gut microbiota unbalance with consequences, as reported in current literature, in cardio vascular disease, diabetes mellitus, rheumatoid arthritis, and Alzheimer’s disease. Likewise, there is the need to highlight and develop a novel philosophical approach in the treatments for oral diseases that will necessarily involve non-conventional approaches.

Body-temperature elevations are multifactorial in origin and classified as hyperthermia as a rise in temperature due to alterations in the thermoregulation mechanism; the body loses the ability to control or regulate body temperature. In contrast, fever is a controlled state, since the body adjusts its stable temperature range to increase body temperature without losing the thermoregulation capacity. Fever refers to an acute phase response that confers a survival benefit on the body, raising core body temperature during infection or systemic inflammation processes to reduce the survival and proliferation of infectious pathogens by altering temperature, restriction of essential nutrients, and the activation of an immune reaction. However, once the infection resolves, the febrile response must be tightly regulated to avoid excessive tissue damage. During fever, neurological, endocrine, immunological, and metabolic changes occur that cause an increase in the stable temperature range, which allows the core body temperature to be considerably increased to stop the invasion of the offending agent and restrict the damage to the organism. There are different metabolic mechanisms of thermoregulation in the febrile response at the central and peripheral levels and cellular events. In response to cold or heat, the brain triggers thermoregulatory responses to coping with changes in body temperature, including autonomic effectors, such as thermogenesis, vasodilation, sweating, and behavioral mechanisms, that trigger flexible, goal-oriented actions, such as seeking heat or cold, nest building, and postural extension. Infrared thermography (IRT) has proven to be a reliable method for the early detection of pathologies affecting animal health and welfare that represent economic losses for farmers. However, the standardization of protocols for IRT use is still needed. Together with the complete understanding of the physiological and behavioral responses involved in the febrile process, it is possible to have timely solutions to serious problem situations. For this reason, the present review aims to analyze the new findings in pathophysiological mechanisms of the febrile process, the heat-loss mechanisms in an animal with fever, thermoregulation, the adverse effects of fever, and recent scientific findings related to different pathologies in farm animals through the use of IRT.

The yellow pigment curcumin, extracted from turmeric, is a renowned polyphenol with a broad spectrum of health properties such as antioxidant, anti-inflammatory, anti-cancer, antidiabetic, hepatoprotective, anti-allergic, anti-dermatophyte, and neuroprotective. However, these properties are followed by a poor pharmacokinetic profile which compromises its therapeutic potential. The association of low absorption by the small intestine and the extensive reductive and conjugative metabolism in the liver dramatically weakens the oral bioavailability. Several strategies such as inhibition of curcumin metabolism with adjuvants as well as novel solid and liquid oral delivery systems have been tried to counteract curcumin poor absorption and rapid elimination from the body. Some of these drug deliveries can successfully enhance the solubility, extending the residence in plasma, improving the pharmacokinetic profile and the cellular uptake.
