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:
Coronaviruses cause a large variety of diseases in humans, livestock, companion and also in wild animals. Three times in the 21st century, coronavirus outbreaks (SARS, MERS and COVID-19), have emerged from animal reservoirs to cause severe diseases in humans and global transmission concerns. There are hundreds of coronaviruses, most of which circulate among animals including pigs, cattle, ferrets, rabbits, camels, bats, cats and dogs. Transmissible gastroenteritis virus (TGE-CoV), and porcine epidemic diarrhea virus (PED-CoV), cause severe gastroenteritis in young piglets, leading to significant morbidity, mortality, and ultimately economic losses. Bovine CoV, Rat CoV, and infectious bronchitis virus (IBV), cause mild to severe infections in cattle, rats, and chickens, respectively. Feline coronavirus enteritis causes a mild or asymptomatic infection in domestic cats, but feline infectious peritonitis coronavirus (FIP-CoV), causes a lethal disease in the domestic cat, and other members of the Felidae family. Sometimes, animal coronaviruses evolve to infect a new host species and spread in that new host, animal or human, causing disease. This host jump or cross-species transmission may lead to serious consequences for a new host population. This review focuses on the etiology, epidemiology, disease mechanisms and pathogenesis as well as bioasecurity and immunoprophylaxis against coronaviral infections.

Opis:
There are many factors involved in the emergence of new infectious diseases or the re-emergence of “old” infectious diseases. Some, result from natural processes such as the evolution of pathogens over time, but many are a result of climate changes, environment pollution, antimicrobial medications and immunosuppression. Lipophilic yeasts Malassezia are associated with diseases affecting animal and human skin. They may also aggravate cutaneous disorders, such as seborrheic dermatitis or exacerbate the course of psoriasis and atopic dermatitis. Due to their specific cell structure, yeasts may be resistant to environmental stress and difficult to eliminate by the host’s immune system. This article outlines the epidemiology, risk factors, pathogenesis, clinical manifestations, and treatment of various human and animals skin infections related to the Malassezia species.

Opis:
Throughout the course of civilization, epidemics and pandemics have ravaged humanity, destroyed animal breeding and horticulture, and has also changed the course of history. It has been estimated that Justinian plague has affected half of the population of Europe and killed in three pandemics 50 million people, the avian-borne flu (Spanish flu), resulted in 50 million deaths worldwide in the years 1918–1919, and recently the COVID-19 is officially a pandemic, after barreling through 114 countries in just three months. In the past, rinderpest has hit Europe with three long panzootics, African swine fever (ASF), is still a threat to both the swine production industry and the health of wild boar populations. Several molecular changes occur in the pathogen that may trigger an epidemic or even pandemic. These include increase of virulence, introduction into a novel host, and changes in host susceptibility to the pathogen. Once the infectious disease threat reaches an epidemic or pandemic level, the goal of the response is to mitigate its impact and reduce its incidence, morbidity and mortality as well as disruptions to economic, political, and social systems. An epidemic curve shows progression of illnesses in an outbreak over time and the SIR, SI, SIRD and SEIR represent the simplest compartmental models that enable simplify the mathematical modelling of epidemics. This article throws a light on changing ideas in epidemiology of infectious diseases.

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.

Opis:
This review aims at the presentation of rare, sporadic infection in animals and humans, following contact with contaminated water. Pythiosis, caused by a water mould Pythium insidiosum, occurs primarily in dogs, horses and humans, but can also affect calves, sheep, cats, birds and even panthers and tigers. Susceptible hosts become infected after contact with motile zoospores, that invade the wounded skin when the animals wade in stagnant water containing this opportunistic organism. In dogs, pythiosis affects the gastrointestinal system and lymph nodes, and seldom the skin. The clinical symptoms include vomiting, weight loss, intermittent diarrhea and palpable masses in the abdomen. Expansion of the infection to the pancreas, mesenteric lymph nodes and bile ducts can occur. Extensive weight loss may be evident. Cutaneous pythiosis is the usual presentation in horses. Skin lesions are pyogranulomatous or fibrogranulomatous and tend to be progressive. In the horse the lesions are large (up to 45 cm), discharging swellings, usually on the extremities, ventral trunk or head. Yellow, necrotic masses termed “kunkers” or “leeches” can be removed intact from the granulomas. Nasal mucosa can be involved. The respiratory condition caused by inhalation of aerosolized Pythium spores is a Pythium-induced allergic syndrome. In humans, three forms of pythiosis are observed: granulomatous and ulcerative lesions involving the skin and subcutaneous tissues of the limbs and face, ophthalmic pythiosis causing keratitis, and systemic pythiosis with vascular involvement leading to vasculitis, thrombosis and aneurysms.

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:
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.

Opis:
Clostridioides (Clostridium) difficile is the most common cause of antibiotic and hospital associated diarrhea and severe colitis in humans and also in dogs, cats, horses, cattle and pigs. It appears to be an emerging zoonotic and reversely zoonotic pathogen The primary virulence factors of C. difficile are the two major toxins, toxin A (TcdA) and toxin B (TcdB). Some strains of C. difficile may also produce an ADP-ribosylating binary toxin (CDT). Dogs and cats in animal shelters are a reservoir of human pathogenic C. difficile. Small animals can potentially act as vectors for the transmission of the organism to humans via direct contact or indirect transmission through raw food, or through contaminated water. Inversely, toxin producing ribotypes 014, 027 and 078 of C. difficile can be transmitted from humans to animals. Our article aims at the presentation of this emerging animal associated disease, its pathogenesis, and methods of control.

Opis:
Borna disease virus (BoDV, Orthobornavirus; Bornaviridae), is the causative agent of Borna disease, mostly lethal polioencephalomyelitis that affects primarily horse and sheep but also and other mammals. It is ssRNA virus, that replicates within the nucleus of target cells, at first at the entry site, than it migrates intraaxonally towards the brain, cerebellum and medulla oblongata. The infection of the central nervous system results in severe neurological disorder that is caused primarily by the hosts cell-mediated immunopathological reactions. The clinical manifestations of the bornaviral diseases are highly variable. Thus, in addition to acute, lethal encephalitis, they can cause persistent neurologic disease associated with diverse behavioral changes. They also cause a severe retinitis resulting in blindness. The zoonotic potential of the virus has been a matter of an unresolved scientific dispute for decades. The impact of BDV on mental health still remains controversial. BoDV‑1 can induce encephalitis cases, establishing the infection as a potentially lethal zoonosis which can impact both immunocompromised and healthy individuals. Diagnosis can be made serologically (ELISA, IF, Western blot), but detection of antigen markers in peripheral white blood cells (ELISA, FACS) and/or in the brain combined with nucleic acid amplification (nested RT-PCR), is more profitable.

Opis:
This review aims to summarize the latest development in the epidemiology, pathology, clinic and control of lumpy skin disease (LSD), with the focus on its transboundary spread, possible emergence and economic implications for on cattle production. This notifiable disease is endemic in African and Middle East countries but has started spreading to Asia and south-east Europe, affecting Greece and Bulgaria and countries in the Balkans. Lumpy skin disease is mainly transmitted to infection-free areas by transport of infected animals and by virus vectors, as blood-feeding insects, such as certain species of flies and mosquitoes, or ticks. There is also growing importance of the spread of wildlife, the potential reservoirs of the disease. Generally, fever, anorexia, hypersalivation, lacrimation and characteristic eruptions with painful nodules within the skin, on the muzzle and within the nasal and buccal mucous membranes, on the udder, on genital and rectal mucous membranes. The severe drop in milk production, also abortions, infertility and sometimes death are the clinical manifestations of the disease in a herd. Although the mortality rate is usually less than 10%, the disease morbidity rate can be as high as 100%. The economic significance of LSD is of great concern, given that it threatens international trade and could be used as bioterrorism weapon. Vaccination, strict quarantine measures, limited movement of livestock along with vectors control could be effective for preventing the spread of the disease. Homologous vaccines are more effective than sheeppox virus strain vaccines.

African horse sickness clinical cases

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.

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.
