Pathogen test  The RT-qPCR test detects the genome (RNA) of Equine Encephalosis virus (EEV). Sample 5 mL - blood - K3 EDTA tube 5mL - liquor (CSF) - sterile tube Turnaround time 2 to 5 working days   What is Equine Encephalosis Virus? Equine Encephalosis (EE) is an arthropod borne febrile non contagious disease of equines. The causative virus, Equine encephalosis virus (EEV), has several serotypes (EEV1-EEV7) and the virus has been reported from southern Africa including Kenya, Botswana and South Africa. Clinical signs The name equine encephalosis is misleading as the disease is not primarily a neurological disorder. Although the majority of infections result only in mild clinical signs, in more severe cases clinical signs include a short period (typically two to five days) of fluctuating fever, accompanied by varying degrees of inappetence.  Elevated heart and respiratory rates are also common, and occasionally as a result of nasal congestion, a red-brown discolouration of the mucous membranes may be observed.   Although rare, more severe clinical signs may occur including facial swelling (lips and eyelids), respiratory distress, and petechial haemorrhages of the conjunctivae. Pregnant mares may also abort during their first 5 months of gestation. Neurological signs are atypical, but in certain cases hindquarter ataxia, convulsions, hyper-excitability, and depression have been reported. The mortality rate is normally low, accounting for only 5% of infected animals. Transmission EEV is transmitted by Culicoides spp. All Equidae may be infected, but only horses exhibit symptoms. Serological evidences in endemic countries indicate that zebras and donkeys might maintain EEV circulation; however, their true role in the transmission is still unknown Prevention In the vast majority of cases (c. 90%) the animal will recover without further complications, and a course of anti-inflammatories or appetite stimulants may be administered. Occasionally, antibiotics are prescribed in order to prevent the appearance of secondary infections. Some equids show no clinical signs at all but are biliary carriers. Although in this instance the animal is not in immediate danger, it must be treated in order to prevent the reemergence of the virus were the immune system to be challenged by another disease simultaneously. Due to the absence of an effective vaccine, vector control remains one of the primary methods of prevention. Control of the midges is usually only instigated for domesticated stabled horses, and includes precautionary measures such as the limited use of lights at night, as well as the use of fly repellents and fans.

Pathogen test  This RT-qPCR test detects the genome (RNA) of Equine Influenza Virus Type A. Equine Influenza is a disease listed in the OIE Terrestrial Animal Health Code and countries are obligated to report the occurrence of the disease according to the OIE Code.   Sample 1 nasopharyngeal swab ( see AAEP guidelines)  5 mL - blood - K3 EDTA tube Turnaround time 2 to 5 working days   What is Equine Influenza? Equine Influenza (EI) is a highly contagious though rarely fatal respiratory disease of horses, donkeys and mules and other equidae. The disease has been recorded throughout history, and when horses were the main draft animals, outbreaks of EI crippled the economy. Nowadays outbreaks still have a severe impact on the horse industry. EI is caused by two subtypes of influenza A viruses: H7N7 and H3N8, of the family Orthomyxoviridae. They are related to but distinct from the viruses that cause human and avian influenza. Once introduced into an area with a susceptible population, the disease, with an incubation period of only one to three days, spreads quickly and is capable of causing explosive outbreaks. Crowding and transportation are factors that favour the spread of EI. Clinical signs In fully susceptible animals, clinical signs include fever and a harsh dry cough followed by a nasal discharge. Depression, loss of appetite, muscle pain and weakness are frequently observed. The clinical signs generally abate within a few days, but complications due to secondary infections are common. While most animals recover in two weeks, the cough may continue longer and it may take as much as six months for some horses to regain their full ability. If animals are not rested adequately, the clinical course is prolonged. Transmission Highly contagious, EI is spread by contact with infected animals, which in coughing excrete the virus. Animals can begin to excrete the virus as they develop a fever before showing clinical signs. It can also be spread by mechanical transmission of the virus on clothing, equipment, brushes etc carried by people working with horses. Prevention Vaccination is practiced in most countries. However, due to the variability of the strains of virus in circulation, and the difficulty in matching the vaccine strain to the strains of virus in circulation. Vaccination does not always prevent infection although it can reduce the severity of the disease and speed recovery times. Act immediately if you see flulike signs in your horse, especially if you have multiple animals housed together. Being proactive can help halt disease spread and save money and time. Call your veterinarian and have him or her take nasal swab samples first to determine what pathogen you are dealing with (several diseases can cause similar signs in infected horses) and treat accordingly. Immediately place the horse in question in a quarantine area and thoroughly clean and disinfect any areas or equipment he has been in contact with. Because horses with influenza do not show signs right away, quarantine other horses that have been housed close to the sick one, as they are most likely already infected. Flu’s incubation period, or time that a horse is infectious before showing signs of illness, is about three days. Management techniques can also help reduce disease spread, including designating one person to handle/treat the sick horse, treating the horse at the end of the day/shift (when the handler won’t be coming into contact with other horses), and setting up foot baths with disinfectant solution for handlers to dip their shoes in as they enter and exit the premises. Disinfecting equipment such as buckets and hoses as well as tack can also prevent disease spread. Regardless of your disinfection protocol, be sure to dedicate a separate water bucket and hose for the sick horse.

Pathogen test  The qPCR test detects the genome (DNA) of  Equine Herpesvirus Type 3 (EHV-3), the pathogen responsible for the Equine Coital Exanthema. Molecular detection of EHV-3 by PCR is the most sensitive, specific and accurate tool in assessing the infectivity of an affected horse Sample 5 mL - blood - K3 EDTA tube 1 genital swab - dry swab 20 gr - placental or foetal tissue - sterile flask Turnaround time 2 to 5 working days   What is Equine Coital Exanthema?  Equine Herpesvirus type 3 (EHV-3) causes coital exanthema, a contagious genital infection (vulva in mares, penis and scrotum in stallions), spread venereally and characterised by numerous small blisters or spots, sometimes called ‘the pox’. Clinical signs The clinical presentation of equine coital exanthema (ECE) is characterised by the presence of superficial lesions on the skin of the external genitalia of mares or stallions. The progress of each cutaneous lesion follows a well-defined and predictable course. Transmission Infection by EHV-3 occurs via direct cutaneous contact either during the act of coitus or by the transfer of virus-containing secretions from contaminated objects, such as hands, gloves, instruments, palpation sleeves, sponges and the lips or nose of a horse. The virus is easily transmitted by simple contact with the skin; the epidermal surface need not be damaged for infection to be established. Prevention There is no commercial vaccine against EHV-3. A stringent code of practice should be implemented within breeding sheds following observation of a case of ECE. The three priorities necessary for successful ECE control are: Cessation of breeding of clinically affected animals; Heightened vigilance on the part of personnel for early recognition of new clinical cases; Strict adherence to breeding shed hygiene procedures designed to eliminate mechanical transmission of the virus.

Pathogen test  The qPCR test detects the genome (DNA) of  Equine Herpesvirus Type 2 (EHV-2).  Serological detection of EHV-2 is of limited use to determine the re-activation of this herpesvirus. EHV-2 can remain latent in affected animals while shedding at levels adequate to infect other horses. Molecular detection of EHV-2 by qPCR is the most sensitive, specific and accurate tool in assessing the infectivity of an affected horse. Sample 1 nasopharyngeal swab - dry swab 5 mL - K3 EDTA tube 5 mL - liquor (CSF) - sterile tube Turnaround time 2 to 5 working days   What is Herpesvirus Type 2? Equine Herpesvirus Type1 2 (EHV-2) was recently classified within the Gammaherpesvirinae subfamily. EHV-2 is widely spread in horse populations and it has been isolated from healthy animals as well as from horses with different clinical signs.  EHV-2 is able to establish persistent infections. Various observations indicate that EHV-2 should not be neglected as a pathogen in equids. There are convincing results indicating that EHV-2 has a role as a predisposing factor for Rhodococcus equi invasion in the respiratory tract. Also as been suggested that EHV-2 may play a role in transactivation and reactivation of latent EHV-1 and EHV-4 infections. Clinical signs EHV-2 infection occurs most frequently in young foals, and the most common symptoms are keratoconjunctivitis, respiratory disease with pneumonia and pharyngitis, fever, enlarged lymph nodes, inappetence/anorexia, general malaise, and poor performance. There is no evidence that EHV-2 has abortigenic potential. Transmission The prowess of EHV-2 as a successfully adapted viral parasite of the horse is substantiated by seroepidemiological and virological studies which indicate almost universal acquisition of viral infection by young foals. The limited data collected supports the scenario that EHV-2, in aerosolised infective material excreted from the respiratory tract of another virus-shedding horse, enters the new host through the upper respiratory tract where it infects and replicates first in the respiratory mucosal epithelium. Prenatal infection with EHV-2 has not been recorded, and the virus has not been detected in colostrum or milk. Experimental infection of a mid-gestational equine foetus in utero resulted in normal term delivery, although the foal showed mild rhinitis and conjunctivitis, with nasal shed- ding of EHV-2. Prevention On the basis of evidence suggesting that EHV-2 infection can play an etiological role in predisposing foals to subsequent R. equi pneumonia, both passive immunisation with hyperimmune equine serum against EHV-2 and active immunisation with an vaccine containing EHV-2 glycoprotein antigens have been used, with reported success, for the prophylactic treatment of annual reoccurrences of this highly fatal foal disease. Ocular disease in foals associated with infection by EHV-2 on breeding farms has been successfully treated with ophthalmic ointments containing either idoxuridine or trifluridine together with antibiotics and non-steroidal anti-inflammatory agents.

Pathogen test  The qPCR test detects the genome (DNA) of  Equine Herpesvirus Type 1 (EHV-1). Sample 1 nasal or nasopharyngeal swab ( see AAEP guidelines)  and 5 mL - K3 EDTA tube 5 mL - liquor (CSF) - sterile tube Turnaround time 2 to 5 working days 24-48h - please contact lab    Our lab is approved by FEI for EHV-1 testing. What is Herpesvirus Type 1? Equine herpesvirus-1 (EHV-1) infection is ubiquitous in most horse populations throughout the world, and causes disease in horses and extensive economic losses through frequent outbreaks of respiratory disease, abortion, neonatal foal death, and myeloencephalopathy. Infections caused by EHV-1 are particularly common in young performance horses, and typically result in establishment of latent infection within the 1st weeks or months of life with subsequent viral reactivation causing clinical disease and viral shedding during periods of stress. Clinical signs Relevant effects of this virus on the equine population: Sporadic occurrence of mild respiratory disease associated with pyrexia, principally affecting horses under 2 years of age, can lead to interruptions in athletic training programs; this is economically the least important manifestation of EHV-1 disease. Abortion occurring during the 3rd trimester of pregnancy, results in important economic losses. Outbreaks of neurological disease (equine herpes myeloencephalopathy or EHM) cause suffering and loss of life and also lead to extensive movement restrictions, disrupting breeding or training schedules and causing management difficulties at training centers, race tracks, and horse events. Transmission The most common way for EHV-1 to spread is by direct horse-to-horse contact. This virus is shed from infected horses via the respiratory tract or through direct or indirect contact with an infected aborted foetus and fetal membranes. Horses may appear to be perfectly healthy yet spread the virus via the secretions from their nostrils. It is important to realize that EHV-1 can also be spread indirectly through contact with physical objects contaminated with infectious virus. The air around a horse that is shedding the virus can also be contaminated with infectious virus. Prevention Subdivide horses into the small epidemiologically isolated closed groups. Minimize risks of exogenous and endogenous (stress- induced viral reactivation) introduction of EHV-1. Maximize herd immunity through vaccination. Important measures in the case of an EHV-1 outbreak: Disinfection of areas contaminated by virus from the aborted foetus and placental membranes. Isolation of affected horses. Submission of clinical samples to a diagnostic laboratory. Implementation of hygienic procedures to prevent spread of infection (biosecurity).

Pathogen test  The PCR test detects the genome (DNA) of  Borrelia burgdorferi, the pathogen responsible for the Lyme disease or Borreliose. For animals with clinical signs. Sample 5 mL - blood - K3 EDTA tube Turnaround time 2 to 5 working days   What is Lyme disease? Lyme disease is a tickborne illness that results from infection with members of the Borrelia burgdorferi sensu lato complex. These organisms are maintained in wild animals, but they can affect humans and some species of domesticated animals, like horses. Lyme disease has been reported in North America, Europe, Australia and parts of Asia. Clinical signs Clinical signs appear in less than 10% of horses infected with the bacteria. Signs include: Lameness (usually of larger joints) that shifts from limb to limb; Generalised stiffness; Soreness in the large joints and back; Low-grade fever (which may or may not be present); Behavioural changes such as reluctance to work and irritability; Laminitis (occasionally associated with Lyme disease) Horses do not show a skin rash with Lyme disease. Swelling around a tick bite in a horse is generally due to a reaction to the tick’s saliva, not Lyme disease. Transmission The ticks become infected when they feed on rodents such as the white-footed mouse that carry the bacteria. The tick can then pass on this infection when it feeds on another host, such as a horse or deer. The bacteria migrate from the tick to the horse after 12 to 24 hours of attachment. In areas where the incidence of disease is high among people, only about 50% of horses are likely to become infected. Of these horses, less than 1 in 10 develops clinical signs of the disease. The remaining horses either have subclinical infection (carry the antibodies against the bacteria but remain clinically healthy) or their immune systems fight off the bacteria (and these horses carry the antibodies to Lyme disease for up to a year). People can also be infected with Lyme disease, but there is no risk of the disease being transmitted from horses to humans. Prevention Since there is no vaccine available, prevention is focused on control of the tick population: Perform a daily tick examination. Remember that it takes 12 to 24 hours of attachment for bacteria to migrate from the tick to the host. Treat turned out horses with permethrin-based insect repellents during peak adult deer tick seasons: early spring, late summer, and fall. Minimize habitat for ticks and their hosts.

 Pathogen test  The qPCR test detects the genome (DNA) of Anaplasma phagocytophilum, the bacterium (formerly known as Ehrlichia phagocytophila and Ehrlichia equi)  responsible for the Equine Anaplasmosis. Sample 5 mL - blood - K3 EDTA tube Turnaround time 2 to 5 working days   What is Equine Anaplasmosis? Anaplasmosis is a tick-borne disease caused by the bacterium Anaplasma phagocytophilum that infects white blood cells. The disease is transmitted by ticks. The risk of transmission to people is unclear at this time. Although horses and people appear to be infected with strains of the same bacteria, it is believed that people also acquire the infection from tick bites, and not directly from infected horses. Clinical signs The severity of signs varies with the age of the animal and duration of the illness. Signs may be mild. Horses less than 1 year old may have a fever only; horses 1 to 3 years old develop fever, depression, mild limb swelling, and lack of coordination. Adults exhibit the characteristic signs of fever, poor appetite, depression, reluctance to move, limb swelling, and jaundice. Fever is highest during the first 1 to 3 days of infection, but may last for 6 to 12 days. Signs become more severe over several days. Any existing infection (such as a leg wound or respiratory infection) can be made worse. Transmission The disease is transmitted by ticks. Immature ticks pick up the bacterium from rodents who serve as reservoirs, maintain it as they mature, and then transmit it to the horse they feed off of as adults. It is unknown how long the tick has to be attached before transmission occurs. It takes approximately 2-3 weeks after disease transmission for the horse to develop clinical signs of Anaplasmosis, meaning that by the time signs are noticed the tick is long gone. Phagocytophilum organisms infect neutrophils and eosinophils in the blood. Prevention The disease is easily treated in the early stages using appropriate antibiotics. The severity of the disease is variable; many horses recover after 14 days without treatment. However, rare fatalities have occurred that are believed to be associated with secondary infections. Horses with severe signs and neurologic signs may benefit from injectable corticosteroids. Recovered horses develop immunity for at least 2 years and are not carriers. Tick control measures are mandatory for control of the disease. There is no vaccine.

Pathogen test  The RT-qPCR test detects the genome (RNA) of the Equine Infectious Anaemia Virus (EIAV). This method is used when there are positive/conflicting results on serologic tests. Confirmation of early infection, before serum antibodies to EIAV develop. Equine Infectious Anaemia is a disease listed in the OIE Terrestrial Animal Health Code and countries are obligated to report the occurrence of the disease according to the OIE Code. Sample 5 mL - blood - K3 EDTA tube 1 mL - frozen semen or others Turnaround time 2 to 5 working days   What is Equine Infectious Anemia? Equine infectious anemia is a very old viral disease that affects horses, asses, mules and hinnies worldwide. It is subject to tight controls in the import/export of live equines and their products Clinical signs This infection may have an acute, chronic or sub-clinical (silent) phase. The acute phase characterised by intermittent fever associated with depression, lethargy, increased heart and breathing rates, haemorrhaging, diarrhoea with blood, bleeding wounds that won’t heal, lack of coordination and rapid weight loss. It can also cause petechial haemorrhages of the mucous membranes and general oedema more evident in the legs and jaundice. The chronic phase characterised by recurrent episodes of fever, anaemia and thrombocytopenia (decrease of blood platelets) interspersed with periods of normality. These episodes will be spread out over time. This disease is often fatal during the acute or chronic phase. Should the animal survive the acute and chronic phase, it enters a silent phase with no evident signs of illness for the remainder of its life. In this silent phase the virus persists but the clinical signs are only manifest if the immune system is weakened by another disease, stress or the administration of corticosteroids. Transmission EIA is caused by a lentivirus of the HIV family, the equine infectious anaemia virus. The virus can be passed from one horse to another through fly, or more rarely, mosquito bites, or by direct contact with blood or blood derivative products (serum and/or plasma). Such as, for example, by: sharing objects contaminated with infected blood (needles, branding tools, etc). The virus can also be passed down from mare to foal via the placenta or, more rarely, in the mother’s colostrum or milk. Potentially, the virus can be transmitted by semen. Prevention There is no treatment, cure or vaccine for this infection. Prevention is crucial to avoid it being passed on. Serological tests for EIA must be done for any horse with anaemia and thrombocytopenia of unknown origin. Regular tests must be done on a yearly basis to keep the holding free from EIA. It is advisable to test studs and brood mares every 90 days in the breeding period.
