    Opis:
    This article aims at presenting an emerging, yeast-related, health threat. Candida auris (Metschnikowiaceae, Candida/Clavispora clade), is an emerging fungus, that presents a serious global health threat. It causes wounds, ears, respiratory and urinary tracts infections. In some patients, these yeasts can enter the bloodstream and spread throughout the body, causing serious systemic infections. C.auris is often resistant to commonly used antifungal drugs, such as amphotericin B, polyenes or echinocandins, making infections difficult to treat. C. auris persists in the environment for months, and persistent environmental contamination, contaminated medical equipment and other fomites, are believed to play a role in nosocomial C. auris transmission. Specialized laboratory methods (RT-PCR, MALDI-TOF MS), are needed to accurately identify C. auris yeast. Echinocandins are currently recommended as first-line therapy in adults and in infants (children above 2 months of age). For neonates amphotericin B deoxycholate is recommended. It is suspected, that C. auris may also be pathogenic to animals.

    Opis:
    Monkeypox is an emerging zoonotic disease and a potential biological weapon. It is caused by enveloped, complex, double-stranded DNA Orthopoxvirus (Poxviridae), closely related to smallpox virus. Since 1958 monkeypox has been reported in people in several central and western African countries, USA and Europe. Transmission of monkeypox virus (MPV), occurs when a person comes into close contact with skin lesions, body fluids, respiratory droplets from infected animal or human, or with contaminated fomites. Monkeypox is a communicable disease in nonhuman primates, wild rodents and prairie dogs. Clinical symptoms in prairie dogs and hon-human primates include cough, history of fever, conjunctivitis, lack of appetite, respiratory signs and rash. In humans, the disease begins with fever, headache, muscle aches, and exhaustion. The patient develops a rash progressing to macules, papules, vesicles, pustules and scabs, often resembling chickenpox. In monkeypox human cases lymphadenopathy is prominent distinguishing this disease from smallpox, already eradicated worldwide. In the African epidemics, 90% of the patients were children below 15 years of age. Monkeypox can be diagnosed with molecular methods (RT-PCR, pan-orthopox PCR), immunohistochemistry, isolation of MPV in cell culture, ELISA and or electron microscopy. To treat patients and to control monkeypox outbreak, the smallpox vaccine, antivirals drugs, and vaccinia immune globulin (VIG) can be used. Monkeypox is a disease of global public health importance and in this article major issues related to this emerging zoonosis are presented.

    Opis:
    This article aims at presenting Nipah virus (NiV), which is becoming a serious threat for animal breeding, as a zoonotic agent and as a potential biological weapon. Nipah virus is a paramyxovirus, genus Henipavirus, whose reservoir host are is fruit bats of the genus Pteropus. The virus can cause severe respiratory disease in resulting in significant economic losses, and also in other animals: horses, cattle, and in cats and dogs. Clinical signs in pigs vary, depending on the age and the individual response to the virus. In general, mortality is low, except in piglets. however, morbidity is high in all age groups. If an outbreak is suspected, the animal premises should be quarantined immediately. Culling of animals with respiratory signs and the close supervision of burial or incineration of carcasses may be necessary to reduce the risk of NiV transmission to people. Restricting or banning the movement of animals from infected farms to other areas can reduce the spread of the disease. The Nipah virus can be transmitted to humans from bats or pigs or from contaminated foods. It can also be transmitted directly between humans. Resulting severe illness is characterized by encephalitis and/or respiratory disease and fatality rate is estimated at 40% to 75%. There is one vaccine available for both people and animals. The NiV to be considered as potential agent of bioterrorism.

    Opis:
    This article aims at the reviewing current measures in prophylaxis and treatment of tetanus, well known neuroinfection, frequently met in farm animals and also in companion animals. Tetanus is a common neurologic disease, occurring as well in humans and characterized by spastic paralysis. It is caused by tetanus toxin, tetanospasmin, produced by Clostridium tetani, environmental, soil borne, anaerobic, Gram-positive, sporulating bacterium.Horses and humans appear to be the most susceptible of all mammals, whereas cattle, dogs, and cats are more resistant. The usual route of infection is a soil-contaminated injury, particularly deep, penetrating wounds, where necrotic tissues promote germination of spores, multiplication of anaerobic C. tetani and toxin production. The wound may be trivial, even unnoticed. The diagnosis of tetanus is mainly based on the typical clinical signs: jaw cramping, muscle spasm, painful muscle stiffness, seizures, changes in blood pressure and heart rate, and also on ELISA testing for tetanospasmin. Identification of C. tetani at the portal of entry is often difficult. Prevention of tetanus depends on the regular immunization with tetanus toxoid. Treatment consists of wound care, medications to ease symptoms and supportive care.

    African horse sickness clinical cases
    diagnosis
    prophylaxis
    Opis:
    African horse sickness is a highly infectious and devastating disease that causes great suffering and many fatalities in equids. It commonly affects horses, mules, donkeys and dogs. The disease is caused by nine different serotypes of the African horse sickness virus, ASHV, genus Orbivirus (Reoviridae), and it is spread mainly by hematophagous arthropods of the Culicoides. Some crossreactions are observed between 1 and 2,3 and 7,5 and 8, and 6 and 9 serotypes. Clinical forms of AHS include peracute pulmonary, subacute cardiac, and mixed as well as subclinical (horse sickness fever). The most severe, with mortality rates exceeding 95%, is the pulmonary form, accompanied by fever, mild depression, sweating, spasmodic coughing, anorexia and respiratory distress. The subacute cardiac form with a mortality of about 50%, is characterized by fever, swelling of the head, neck and supraorbital fossae and sometimes, petechial hemorrhages in the eyes. The mildest form of the disease is generally not fatal and is accompanied by a low grade fever, anorexia, depression and congestion of the mucous membranes. The most common cases with a 70% mortality rate, are mixture of the pulmonary and cardiac forms. Differential diagnosis include equine encephalosis virus (also Orbivirus), equine infectious anemia, equine viral arteritis, anaplasmosis, babesiosis, or theileriosis. Clinical AHS cases have also been described in dogs, with acute respiratory distress syndrome or sudden death. Diagnosis of the disease is based on typical clinical signs and lesions, a history consistent with vector transmission and confirmation by laboratory detection of virus and/or anti-virus antibodies. Currently, prevention and control of African horse sickness is based on administration of live attenuated vaccines and control of the arthropod vectors.

    Bluetongue virus, BTV, (Orbivirus; Reoviridae), can infect many domesticated and wild ruminants including cattle, sheep, goats, various cervids and wildebeest. Bluetongue can be found on all continents except Antarctica. The virus is transmitted by the midges (Culicoides), the only significant natural transmitters of bluetongue. Multiple BTV serotypes can be found in many regions of the world. Serotypes 1, 8 and 26 can be transmitted between ruminants in close contact with blood and semen. Clinical cases of bluetongue occur mainly in sheep, while subclinical infections seem to predominate in most other species. Bluetongue virus can be found in blood from live animals and in spleen, lymph nodes or bone marrow samples collected at necropsy. RT-PCR tests are widely used to identify viral RNA in clinical samples, and identify the serotype. A variety of vaccination strategies are available for immunization of ruminant livestock against BTV infection. This article aims at presentation of achievements and failures in the worldwide efforts of bluetongue control.

    Opis:
    This review aims at presentation of a group of parvoviruses, that gain the significance in small animals. Bocaparvovirus 1 (CaBoV1, minute virus of canines), was identified in 1967. Majority of CaBoV1 infections in dogs appear to be subclinical. However, there are also studies, confirming that CaBoV1 is dangerous, especially for developing fetuses, for young puppies and for elderly dogs. Canine Bocaparvovirus 2 (CaBoV2), was identified in 2012 in a litter of puppies, in association with respiratory signs resulting from interstitial pneumonia and with massive enteritis with atrophied and fused villi, severe crypts regeneration, and severe bone marrow and lymphoid atrophy. A third canine bocaparvovirus (CaBoV3), was identified in the liver of a dog with circovirus coinfection. In 2005, the human bocavirus (HBoV), has been isolated from respiratory tract and has been reported worldwide with frequencies ranging from 1.5 to 18.3% in samples from children with upper respiratory tract infections. Three more enteric, human bocaviruses (HBoV2–4), have been found in stool samples. HBoV infections are significantly more frequent in children from 6 month to 3 year of age. So far, no HBoV-specific clinical symptoms are known. Bocaparvoviruses were also isolated from other animal species, including pigs, cats, gorilla, sea lions, rodents and bats.

    Lassa fever
    Opis:
    Lassa virus (Arenaviridae), is the etiological agent of Lassa fever, a severe human disease with high mortality rates for hospitalized patients. Lassa fever can be difficult to distinguish clinically from other viral hemorrhagic fevers. The virus is initially spread to people via contact with urine or feces of an infected multimammate mouse and rat, that remain carriers for life. Once infected, people may transmit Lassa virus in both community and health care settings, by contaminated medical equipment and direct contact with bodily secretions. About 15–20% of hospitalized people with Lassa fever will die from the illness. However, many infected people do not develop symptoms, which typically include fever, headache, vomiting and muscles pain. The main feature of fatal illness is impaired or severely delayed cell mediated immunity leading to fulminant viremia. Early recognition and initiation of targeted care increase patients surviving rates. Lassa fever is diagnosed by ELISA, which may detect IgM and IgG antibodies as well as Lassa virus antigen and RT-PCR used in the early stage of disease. There is currently no licensed vaccine against Lassa fever, and the only treatment available is based on ribavirin. In this article epidemiological aspects as well as diagnostics approaches are presented and discussed in the context of possibly increasing the public health threat with Lassa fever in European countries.

    Opis:
    Swine acute diarrhea syndrome coronavirus (SADS-CoV), a newly emerging enteric coronavirus in China, is associated with swine acute diarrhea syndrome (SADS), which has caused significant economic losses to the porcine industry. SADS-CoV has a very broad species tropism in vitro and can infect cell lines from 24 different animal species. Moreover, virus transmission, replication and in vitro gene expression is possible in on human cells of the liver, gut, and airway origin. Interestingly, none of the known human coronavirus receptors functions as a receptor for SADS-CoV. Also, SADS-CoV infection has not induced IFN‑β. Bats are considered to play an important role in epidemiology of swine disease. It is possible, that as bats prey on insects near pig facilities, their feces containing bat-HKU2-like porcine CoVs, contaminate swine feed, which is then eaten by pigs and rodents, that subsequently become carriers of SADS-CoV. The zoonotic transmission of novel coronaviruses into humans presents severe threats to the global health.

    Opis:
    Severe fever with thrombocytopenia syndrome (SFTS), is an emerging infectious zoonotic disease caused by a new phlebovirus, namely Huaiyangshan banyangvirus (family Phenuiviridae, Bunyavirales). The disease presents various clinical manifestations, including high fever, gastrointestinal signs, neurological signs, thrombocytopenia, leukocytopenia, lymphadenopathy and multiple organ failure, shown by elevated levels of serum alanine aminotransferase, aspartate aminotransferase, creatine kinase, and lactate dehydrogenase. SFTSV is transmitted by a bush tick, Haemaphysalis longicornis, bites and human-tohuman transmission has also been reported. SFTSV attacks primarily goats, cattle, dogs, cats, pigs, deer, elks, wild boars, chickens, rodents and shrews, small insectivorous mammals, but the clinical manifestations of SFTS have been reported mainly in dogs and cats. Dogs and cats, which live in close contact with their owners, serve as important mediators for transmitting virus to humans. Effective therapies or vaccines are not yet available. This review describes the different aspects of virology, pathogenesis, epidemiology and clinical symptoms of SFTS in animals and also in humans.

    Opis:
    This article aims at presentation of disease in sheep that follows upset in gut microbiota, due to sudden changes to a rich diet. Enterotoxemia (pulpy kidney disease), most commonly occurs in rapidly growing or weaned lambs, when there is a rapid shift to a low fiber and high carbohydrate diet. The disease develops when Clostridium perfringens type D, that normally inhabits the animal intestines, begins to multiply fast and produces an epsilon toxin that results in toxemia and frequently, the sudden death. Rapid multiplication of type D and epsilon toxin production is favored by excess of dietary starch in the small intestine. C. perfringens type D can also cause a chronic form of the disease – focal, symmetrical encephalomalacia. Diagnosis is based on clinical signs, history of sudden death cases in herd and confirmation by necropsy, brain histopathology, bacteriological examination, RT-PCR and ELISA. Treatment, prevention and control of pulpy kidney disease depends on serotherapy with antitoxin, supportive treatment and correction of diet and vaccination. Effective vaccines are commercially available. All animals in the herd, especially the young ones, should be vaccinated to minimize the risk of enterotoxemia in sheep.

    Opis:
    Maedi-visna is a multi-systemic disease of sheep caused by a non-oncogenic, exogenous retrovirus of the Lentiviridae subfamily. It is mainly transmitted through the ingestion of milk from infected sheep, although disease can be spread within flocks through direct contact and transmission can occur also in utero. Maedi usually begins insidiously and leads to a classical interstitial pneumonia. On postmortem examination, the lungs may be 2-4 times heavier than normal, due to decreased elasticity and fibrosis. Regional lymph nodes are enlarged with formation of lymphoid follicles with active germinal centers. Visna - the neurological form of the disease, is characterized by chronic and active meningoencephalomyelitis and chorioiditis with massive infiltrations of mononuclear cells around the blood vessels, microglial nodules formation and astrogliosis. Virus isolation is very specific but of variable sensitivity. The cytopathic effects are characteristic, consisting of the appearance of stellate cells and syncytia. The diagnostic methods currently used are based on the detection of either antibodies or the viral genome. The three most commonly tests used, are the PCR and RT-PCR, agar gel immunodiffusion test (AGID) and the enzyme-linked immunosorbent assay (ELISA). Western blot analysis and radio-immunoprecipitation are also performed, but only in specialized laboratories. No commercial vaccines are available to control infection, and to date, monitoring programs have proved to be the only effective tool in controlling this disease.

    Opis:
    Here, an emerging, threatening disease, influenza in dogs, is presented. Like other mammalian influenza viruses, canine influenza virus (CIV), causes an acute respiratory infection. There is no season for this disease and infections can occur any time of the year. Dogs have acquired two influenza viruses since 1999. Canine influenza H3N8 virus is thought to develop from an equine H3N8 strain, whereas canine H3N2 influenza virus most likely arose through the direct transfer of an avian influenza virus from birds. The H3N8 CIV has only been reported in dogs, whereas the H3N2 CIV has caused clinical cases in dogs and cats in Asia, and antibodies to this virus have been found in both species. Almost all dogs exposed to canine influenza virus become infected, with approximately 80% developing clinical signs of disease. Some dogs have asymptomatic infections, while some have severe illness, however death cases due to CIV infection are rare. Fatal H3N8 cases in racing greyhounds were often characterized by hemorrhages in the lungs, mediastinum and pleural cavity. Severe hemorrhagic, cranio-ventral broncho-interstitial pneumonia was reported in most fatal cases of canine H3N2 influenza in naturally infected dogs from Asia. Experimentally infected dogs also had signs of pneumonia with multifocal to coalescing reddish consolidation, edema and hemorrhages in the lungs. No lesions were found outside the respiratory tract. The majority of infected dogs have the mild form of canine influenza. The approximately 20% of infected animals that do not exhibit clinical signs of disease can still shed the virus. The diagnosis is performed by serological methods, with hemagglutination inhibition (HI) as the test of choice, and by molecular methods as RT-PCR. Treatment is supportive, and often includes antibiotics to control secondary bacterial infections. Vaccines for canine influenza are available in some areas. Infection control measures include isolation of infected animals, cleaning and disinfection of cages, bowls and other fomites, and hygiene measures.
