Acute and persistent infection of human neural cell lines by human coronavirus OC43. (1/49)

Human coronaviruses (HuCV) are recognized respiratory pathogens. Data accumulated by different laboratories suggest their neurotropic potential. For example, primary cultures of human astrocytes and microglia were shown to be susceptible to an infection by the OC43 strain of HuCV (A. Bonavia, N. Arbour, V. W. Yong, and P. J. Talbot, J. Virol. 71:800-806, 1997). We speculate that the neurotropism of HuCV will lead to persistence within the central nervous system, as was observed for murine coronaviruses. As a first step in the verification of our hypothesis, we have characterized the susceptibility of various human neural cell lines to infection by HuCV-OC43. Viral antigen, infectious virus progeny, and viral RNA were monitored during both acute and persistent infections. The astrocytoma cell lines U-87 MG, U-373 MG, and GL-15, as well as neuroblastoma SK-N-SH, neuroglioma H4, oligodendrocytic MO3.13, and the CHME-5 immortalized fetal microglial cell lines, were all susceptible to an acute infection by HuCV-OC43. Viral antigen and RNA and release of infectious virions were observed during persistent HuCV-OC43 infections ( approximately 130 days of culture) of U-87 MG, U-373 MG, MO3.13, and H4 cell lines. Nucleotide sequences of RNA encoding the putatively hypervariable viral S1 gene fragment obtained after 130 days of culture were compared to that of initial virus input. Point mutations leading to amino acid changes were observed in all persistently infected cell lines. Moreover, an in-frame deletion was also observed in persistently infected H4 cells. Some point mutations were observed in some molecular clones but not all, suggesting evolution of the viral population and the emergence of viral quasispecies during persistent infection of H4, U-87 MG, and MO3.13 cell lines. These results are consistent with the potential persistence of HuCV-OC43 in cells of the human nervous system, accompanied by the production of infectious virions and molecular variation of viral genomic RNA.  (+info)

Pigs with highly prevalent antibodies to human coronavirus and swine haemagglutinating encephalomyelitis virus in the Tohoku District of Japan. (2/49)

From 1985 to 1988, a total of 2496 swine sera from 60 farms in the Tohoku District of the Honshu Island of Japan were examined for antibodies to swine haemagglutinating encephalomyelitis virus (HEV), human coronavirus (HCV) and bovine coronavirus (BCV) by haemagglutination-inhibition (HI) test. Antibodies to HEV 67N strain and HCV OC43 strain were highly prevalent with positivity rates of 82.1 and 91.4%, respectively, while seropositivity rate to BCV Kakegawa strain was 44.2%. No clinical signs of HEV infection were noticed in any farms including farms with relatively high seropositivity. The results suggested that HCV or antigenitically related virus(es) as well as HEV might be perpetuated in swine in the Tohoku District.  (+info)

Neuroinvasion by human respiratory coronaviruses. (3/49)

Human coronaviruses (HCoV) cause common colds but can also infect neural cell cultures. To provide definitive experimental evidence for the neurotropism and neuroinvasion of HCoV and its possible association with multiple sclerosis (MS), we have performed an extensive search and characterization of HCoV RNA in a large panel of human brain autopsy samples. Very stringent reverse transcription-PCR with two primer pairs for both viral strains (229E and OC43), combined with Southern hybridization, was performed on samples from 90 coded donors with various neurological diseases (39 with MS and 26 with other neurological diseases) or normal controls (25 patients). We report that 44% (40 of 90) of donors were positive for 229E and that 23% (21 of 90) were positive for OC43. A statistically significant higher prevalence of OC43 in MS patients (35.9%; 14 of 39) than in controls (13.7%; 7 of 51) was observed. Sequencing of nucleocapsid protein (N) gene amplicons revealed point mutations in OC43, some consistently found in three MS patient brains and one normal control but never observed in laboratory viruses. In situ hybridization confirmed the presence of viral RNA in brain parenchyma, outside blood vessels. The presence of HCoV in human brains is consistent with neuroinvasion by these respiratory pathogens. Further studies are needed to distinguish between opportunistic and disease-associated viral presence in human brains.  (+info)

Characterization of a coronavirus isolated from a diarrheic foal. (4/49)

A coronavirus was isolated from feces of a diarrheic foal and serially propagated in human rectal adenocarcinoma (HRT-18) cells. Antigenic and genomic characterizations of the virus (isolate NC99) were based on serological comparison with other avian and mammalian coronaviruses and sequence analysis of the nucleocapsid (N) protein gene. Indirect fluorescent-antibody assay procedures and virus neutralization assays demonstrated a close antigenic relationship with bovine coronavirus (BCV) and porcine hemagglutinating encephalomyelitis virus (mammalian group 2 coronaviruses). Using previously described BCV primers, the N protein gene of isolate NC99 was amplified by a reverse transcriptase PCR (RT-PCR) procedure. The RT-PCR product was cloned into pUC19 and sequenced; the complete N protein of NC99 (446 amino acids) was then compared with published N protein sequences of other avian and mammalian coronaviruses. A high degree of identity (89.0 to 90.1%) was observed between the N protein sequence of NC99 and published sequences of BCV (Mebus and F15 strains) and human coronavirus (strain OC43); only limited identity (<25%) was observed with group 1 and group 3 coronaviruses. Based on these findings, the virus has been tentatively identified as equine coronavirus (ECV). ECV NC99 was determined to have close antigenic and/or genetic relationships with mammalian group 2 coronaviruses, thus identifying it as a member of this coronavirus antigenic group.  (+info)

Vacuolating encephalitis in mice infected by human coronavirus OC43. (5/49)

Involvement of viruses in human neurodegenerative diseases and the underlying pathologic mechanisms remain generally unclear. Human respiratory coronaviruses (HCoV) can infect neural cells, persist in human brain, and activate myelin-reactive T cells. As a means of understanding the human infection, we characterized in vivo the neurotropic and neuroinvasive properties of HCoV-OC43 through the development of an experimental animal model. Virus inoculation of 21-day postnatal C57BL/6 and BALB/c mice led to a generalized infection of the whole CNS, demonstrating HCoV-OC43 neuroinvasiveness and neurovirulence. This acute infection targeted neurons, which underwent vacuolation and degeneration while infected regions presented strong microglial reactivity and inflammatory reactions. Damage to the CNS was not immunologically mediated and microglial reactivity was instead a consequence of direct virus-mediated neuronal injury. Although this acute encephalitis appears generally similar to that induced by murine coronaviruses, an important difference rests in the prominent spongiform-like degeneration that could trigger neuropathology in surviving animals.  (+info)

Frequent detection of human coronaviruses in clinical specimens from patients with respiratory tract infection by use of a novel real-time reverse-transcriptase polymerase chain reaction. (6/49)

During the past years, human coronaviruses (HCoVs) have been increasingly identified as pathogens associated with more-severe respiratory tract infection (RTI). Diagnostic tests for HCoVs are not frequently used in the routine setting. It is likely that, as a result, the precise role that HCoVs play in RTIs is greatly underestimated. We describe a rapid, sensitive, and highly specific quantitative real-time reverse-transcriptase polymerase chain reaction (RT-PCR) for the detection of HCoV that can easily be implemented in the routine diagnostic setting. HCoV was detected in 28 (11%) of the 261 clinical specimens obtained from patients presenting with symptoms of RTI ranging from common cold to severe pneumonia. Only 1 (0.4%) of the 243 control specimens obtained from patients without symptoms of RTI showed the presence of HCoV. We conclude that HCoVs can be frequently detected in patients presenting with RTI. Real-time RT-PCR provides a tool for large-scale epidemiological studies to further clarify the role that coronavirus infection plays in RTI in humans.  (+info)

Human respiratory coronavirus OC43: genetic stability and neuroinvasion. (7/49)

The complete genome sequences of the human coronavirus OC43 (HCoV-OC43) laboratory strain from the American Type Culture Collection (ATCC), and a HCoV-OC43 clinical isolate, designated Paris, were obtained. Both genomes are 30,713 nucleotides long, excluding the poly(A) tail, and only differ by 6 nucleotides. These six mutations are scattered throughout the genome and give rise to only two amino acid substitutions: one in the spike protein gene (I958F) and the other in the nucleocapsid protein gene (V81A). Furthermore, the two variants were shown to reach the central nervous system (CNS) after intranasal inoculation in BALB/c mice, demonstrating neuroinvasive properties. Even though the ATCC strain could penetrate the CNS more effectively than the Paris 2001 isolate, these results suggest that intrinsic neuroinvasive properties already existed for the HCoV-OC43 ATCC human respiratory isolate from the 1960s before it was propagated in newborn mouse brains. It also demonstrates that the molecular structure of HCoV-OC43 is very stable in the environment (the two variants were isolated ca. 40 years apart) despite virus shedding and chances of persistence in the host. The genomes of the two HCoV-OC43 variants display 71, 53.1, and 51.2% identity with those of mouse hepatitis virus A59, severe acute respiratory syndrome human coronavirus Tor2 strain (SARS-HCoV Tor2), and human coronavirus 229E (HCoV-229E), respectively. HCoV-OC43 also possesses well-conserved motifs with regard to the genome sequence of the SARS-HCoV Tor2, especially in open reading frame 1b. These results suggest that HCoV-OC43 and SARS-HCoV may share several important functional properties and that HCoV-OC43 may be used as a model to study the biology of SARS-HCoV without the need for level three biological facilities.  (+info)

Complete genomic sequence of human coronavirus OC43: molecular clock analysis suggests a relatively recent zoonotic coronavirus transmission event. (8/49)

Coronaviruses are enveloped, positive-stranded RNA viruses with a genome of approximately 30 kb. Based on genetic similarities, coronaviruses are classified into three groups. Two group 2 coronaviruses, human coronavirus OC43 (HCoV-OC43) and bovine coronavirus (BCoV), show remarkable antigenic and genetic similarities. In this study, we report the first complete genome sequence (30,738 nucleotides) of the prototype HCoV-OC43 strain (ATCC VR759). Complete genome and open reading frame (ORF) analyses were performed in comparison to the BCoV genome. In the region between the spike and membrane protein genes, a 290-nucleotide deletion is present, corresponding to the absence of BCoV ORFs ns4.9 and ns4.8. Nucleotide and amino acid similarity percentages were determined for the major HCoV-OC43 ORFs and for those of other group 2 coronaviruses. The highest degree of similarity is demonstrated between HCoV-OC43 and BCoV in all ORFs with the exception of the E gene. Molecular clock analysis of the spike gene sequences of BCoV and HCoV-OC43 suggests a relatively recent zoonotic transmission event and dates their most recent common ancestor to around 1890. An evolutionary rate in the order of 4 x 10(-4) nucleotide changes per site per year was estimated. This is the first animal-human zoonotic pair of coronaviruses that can be analyzed in order to gain insights into the processes of adaptation of a nonhuman coronavirus to a human host, which is important for understanding the interspecies transmission events that led to the origin of the severe acute respiratory syndrome outbreak.  (+info)

Human coronavirus OC43 (HCoV-OC43) is a species of coronavirus that causes respiratory infections in humans. It is one of the several coronaviruses known to cause the common cold. HCoV-OC43 belongs to the genus Betacoronavirus and is an enveloped, positive-sense, single-stranded RNA virus.

The virus was first identified in 1967 and has since been found to be widely distributed throughout the human population. It is estimated that HCoV-OC43 infections occur annually, with a peak incidence during the winter months in temperate climates. The symptoms of HCoV-OC43 infection are typically mild and include nasal congestion, runny nose, sore throat, and cough.

HCoV-OC43 is transmitted through respiratory droplets produced when an infected person talks, coughs, or sneezes. The virus can also be spread by touching contaminated surfaces and then touching the mouth, nose, or eyes. There is no specific treatment for HCoV-OC43 infections, and management is generally supportive, with rest, hydration, and symptomatic relief of fever and cough.

HCoV-OC43 has been identified as one of the coronaviruses that have the potential to cause severe respiratory illness in immunocompromised individuals or those with underlying medical conditions. However, most HCoV-OC43 infections are mild and do not require hospitalization.

Coronaviruses are a large family of viruses that can cause illnesses ranging from the common cold to more severe diseases such as pneumonia. The name "coronavirus" comes from the Latin word "corona," which means crown or halo, reflecting the distinctive appearance of the virus particles under electron microscopy, which have a crown-like structure due to the presence of spike proteins on their surface.

Coronaviruses are zoonotic, meaning they can be transmitted between animals and humans. Some coronaviruses are endemic in certain animal populations and occasionally jump to humans, causing outbreaks of new diseases. This is what happened with Severe Acute Respiratory Syndrome (SARS) in 2002-2003, Middle East Respiratory Syndrome (MERS) in 2012, and the most recent Coronavirus Disease 2019 (COVID-19), caused by SARS-CoV-2.

Coronavirus infections typically cause respiratory symptoms such as cough, shortness of breath, and fever. In severe cases, they can lead to pneumonia, acute respiratory distress syndrome (ARDS), and even death, especially in older adults or people with underlying medical conditions. Other symptoms may include fatigue, muscle aches, headache, sore throat, and gastrointestinal issues such as nausea, vomiting, and diarrhea.

Preventive measures for coronavirus infections include frequent hand washing, wearing face masks, practicing social distancing, avoiding close contact with sick individuals, and covering the mouth and nose when coughing or sneezing. There are currently vaccines available to prevent COVID-19, which have been shown to be highly effective in preventing severe illness, hospitalization, and death from the disease.

A coronavirus is a type of virus that causes respiratory illnesses, such as the common cold, and more severe diseases including Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). These viruses are typically spread through close contact with an infected person when they cough or sneeze. They can also spread by touching a surface or object that has the virus on it and then touching your own mouth, nose, or eyes.

Coronaviruses are named for the crown-like spikes on their surface. They are zoonotic, meaning they can be transmitted between animals and people. Common signs of infection include fever, cough, and shortness of breath. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and even death.

One of the most recently discovered coronaviruses is SARS-CoV-2, which causes the disease COVID-19. This virus was first identified in Wuhan, China in late 2019 and has since spread to become a global pandemic.

Coronaviridae is a family of enveloped, positive-sense, single-stranded RNA viruses. They are named for the crown-like (corona) appearance of their surface proteins. Coronaviruses infect a wide range of animals, including mammals and birds, and can cause respiratory, gastrointestinal, and neurological diseases. Some coronaviruses, such as Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome Coronavirus (MERS-CoV), can cause severe and potentially fatal illness in humans. The most recent example is SARS-CoV-2, which causes COVID-19.

Bovine coronavirus (BCoV) is a species of coronavirus that infects cattle and other animals such as yaks, deer, and occasionally humans. It is an enveloped, single-stranded, positive-sense RNA virus belonging to the genus Betacoronavirus in the family Coronaviridae.

BCoV primarily causes respiratory and enteric diseases in cattle, resulting in symptoms such as pneumonia, coughing, diarrhea, and decreased appetite. The virus is transmitted through direct contact with infected animals or their feces, contaminated food, water, or fomites.

In humans, BCoV infection is rare but has been associated with respiratory illnesses in people working closely with cattle, such as farmers, abattoir workers, and veterinarians. The symptoms of human BCoV infection are similar to those caused by other coronaviruses, including fever, cough, and shortness of breath.

Prevention measures for BCoV include good hygiene practices, wearing personal protective equipment when working with cattle, and vaccination of animals against the virus. There is currently no specific treatment or vaccine available for human BCoV infection.

A spike glycoprotein in coronaviruses is a type of protein that extends from the surface of the virus and gives it its characteristic crown-like appearance (hence the name "corona," which is Latin for "crown"). This protein plays a crucial role in the infection process of the virus. It allows the virus to attach to and enter specific cells in the host organism, typically through binding to a receptor on the cell surface. In the case of SARS-CoV-2, the coronavirus responsible for COVID-19, the spike protein binds to the angiotensin-converting enzyme 2 (ACE2) receptor found on cells in various tissues, including the lungs, heart, and gastrointestinal tract.

The spike protein is composed of two subunits: S1 and S2. The S1 subunit contains the receptor-binding domain (RBD), which recognizes and binds to the host cell receptor. After binding, the S2 subunit mediates the fusion of the viral membrane with the host cell membrane, allowing the viral genome to enter the host cell and initiate infection.

The spike protein is also a primary target for neutralizing antibodies generated by the host immune system during infection or following vaccination. Neutralizing antibodies bind to specific regions of the spike protein, preventing it from interacting with host cell receptors and thus inhibiting viral entry into cells.

In summary, a spike glycoprotein in coronaviruses is a crucial structural and functional component that facilitates viral attachment, fusion, and entry into host cells. Its importance in the infection process makes it an essential target for vaccine development and therapeutic interventions.

Human coronavirus 229E (HCoV-229E) is a species of coronavirus that causes respiratory infections in humans. It is one of the several coronaviruses known to cause the common cold. HCoV-229E was first identified in the 1960s and is named after the number assigned to it in the laboratory where it was discovered.

HCoV-229E infects the human body through the respiratory tract, and it primarily affects the upper respiratory system, causing symptoms such as runny nose, sore throat, cough, and fever. In some cases, HCoV-229E can also cause lower respiratory infections, such as pneumonia, especially in individuals with weakened immune systems or underlying medical conditions.

HCoV-229E is an enveloped, positive-sense, single-stranded RNA virus that belongs to the family Coronaviridae and the genus Alphacoronavirus. It is transmitted through respiratory droplets produced when an infected person coughs, sneezes, or talks. The virus can also survive on surfaces for several hours, making it possible to contract the infection by touching contaminated objects.

There is no specific treatment for HCoV-229E infections, and most people recover within a week or two with rest and symptomatic relief. However, severe cases may require hospitalization and supportive care, such as oxygen therapy and mechanical ventilation. Preventive measures, such as hand hygiene, wearing masks, and avoiding close contact with infected individuals, can help reduce the transmission of HCoV-229E and other respiratory viruses.

Nucleocapsid proteins are structural proteins that are associated with the viral genome in many viruses. They play a crucial role in the formation and stability of the viral particle, also known as the virion. In particular, nucleocapsid proteins bind to the viral RNA or DNA genome and help to protect it from degradation by host cell enzymes. They also participate in the assembly and disassembly of the virion during the viral replication cycle.

In some viruses, such as coronaviruses, the nucleocapsid protein is also involved in regulating the transcription and replication of the viral genome. The nucleocapsid protein of SARS-CoV-2, for example, has been shown to interact with host cell proteins that are involved in the regulation of gene expression, which may contribute to the virus's ability to manipulate the host cell environment and evade the immune response.

Overall, nucleocapsid proteins are important components of many viruses and are often targeted by antiviral therapies due to their essential role in the viral replication cycle.

Severe Acute Respiratory Syndrome (SARS) is a viral respiratory illness caused by the SARS coronavirus (SARS-CoV). This virus is a member of the Coronaviridae family and is thought to be transmitted most readily through close person-to-person contact via respiratory droplets produced when an infected person coughs or sneezes.

The SARS outbreak began in southern China in 2002 and spread to several other countries before it was contained. The illness causes symptoms such as fever, chills, and body aches, which progress to a dry cough and sometimes pneumonia. Some people also report diarrhea. In severe cases, the illness can cause respiratory failure or death.

It's important to note that SARS is not currently a global health concern, as there have been no known cases since 2004. However, it remains a significant example of how quickly and widely a new infectious disease can spread in today's interconnected world.

Feline coronavirus (FCoV) is a type of virus that primarily infects cats. It is part of the Coronaviridae family and has a positive-sense, single-stranded RNA genome. There are two types of feline coronavirus: feline enteric coronavirus (FECV) and feline infectious peritonitis virus (FIPV).

FECV is a relatively harmless virus that primarily causes mild to no symptoms in infected cats, and it is spread through fecal-oral transmission. FECV mainly affects the intestines and can cause diarrhea in some cases.

FIPV, on the other hand, is a mutated form of FECV that can cause a severe and often fatal disease called feline infectious peritonitis (FIP). FIP is an immune-mediated disease characterized by inflammation and accumulation of fluid in the abdomen or chest. It can also affect other organs, such as the eyes, brain, and liver.

It's important to note that not all cats infected with FECV will develop FIP. The development of FIP depends on various factors, including the cat's age, immune system, and the specific strain of the virus. There is no cure for FIP, but supportive care can help manage the symptoms and improve the cat's quality of life.

Respiratory tract infections (RTIs) are infections that affect the respiratory system, which includes the nose, throat (pharynx), voice box (larynx), windpipe (trachea), bronchi, and lungs. These infections can be caused by viruses, bacteria, or, less commonly, fungi.

RTIs are classified into two categories based on their location: upper respiratory tract infections (URTIs) and lower respiratory tract infections (LRTIs). URTIs include infections of the nose, sinuses, throat, and larynx, such as the common cold, flu, laryngitis, and sinusitis. LRTIs involve the lower airways, including the bronchi and lungs, and can be more severe. Examples of LRTIs are pneumonia, bronchitis, and bronchiolitis.

Symptoms of RTIs depend on the location and cause of the infection but may include cough, congestion, runny nose, sore throat, difficulty breathing, wheezing, fever, fatigue, and chest pain. Treatment for RTIs varies depending on the severity and underlying cause of the infection. For viral infections, treatment typically involves supportive care to manage symptoms, while antibiotics may be prescribed for bacterial infections.

Canine coronavirus (CCoV) is a species of coronavirus that infects dogs. It is related to the coronaviruses that cause respiratory illness in humans, such as SARS-CoV and MERS-CoV, but it is not known to infect people. CCoV primarily affects the gastrointestinal tract and can cause symptoms such as vomiting and diarrhea. It is usually spread through contact with infected feces. There are two main types of CCoV, called Type I and Type II, which are classified based on their genetic makeup. Both types can cause illness in dogs, but Type II is more likely to cause severe disease. Vaccines are available to help protect dogs against CCoV infection.

Severe Acute Respiratory Syndrome (SARS) is a viral respiratory illness characterized by fever, cough, shortness of breath, and sometimes severe pneumonia. It is caused by the SARS coronavirus (SARS-CoV).

The syndrome is considered severe due to its potential to cause rapid spread in communities and healthcare settings, and for its high case fatality rate. In the global outbreak of 2002-2003, approximately 8,000 people were infected and nearly 800 died. Since then, no large outbreaks have been reported, although there have been isolated cases linked to laboratory accidents or animal exposures.

SARS is transmitted through close contact with an infected person's respiratory droplets, such as when they cough or sneeze. It can also be spread by touching a surface contaminated with the virus and then touching the mouth, nose, or eyes. Healthcare workers and others in close contact with infected individuals are at higher risk of infection.

Preventive measures include good personal hygiene, such as frequent handwashing, wearing masks and other protective equipment when in close contact with infected individuals, and practicing respiratory etiquette (covering the mouth and nose when coughing or sneezing). Infected individuals should be isolated and receive appropriate medical care to help manage their symptoms and prevent transmission to others.

Coronaviridae is a family of enveloped, positive-sense RNA viruses that cause various diseases in animals and humans. Human coronavirus infections most commonly result in mild to moderate upper respiratory tract illnesses, such as the common cold. However, two highly pathogenic coronaviruses have emerged in the past two decades: Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and Middle East Respiratory Syndrome Coronavirus (MERS-CoV). These viruses can cause severe and potentially fatal respiratory illnesses.

In general, coronaviruses are transmitted through respiratory droplets produced when an infected person coughs, sneezes, or talks. In some cases, people may become infected by touching a surface contaminated with the virus and then touching their mouth, nose, or eyes. Preventive measures include frequent handwashing, avoiding close contact with sick individuals, and practicing good respiratory etiquette (e.g., covering coughs and sneezes).

Treatment for coronavirus infections is primarily supportive, focusing on relieving symptoms and managing complications. For severe cases of SARS-CoV and MERS-CoV infections, antiviral medications and supportive care in an intensive care unit may be necessary. Vaccines have been developed to protect against SARS-CoV-2, the virus that causes COVID-19, and are being distributed globally.

Murine hepatitis virus (MHV) is a type of coronavirus that primarily infects laboratory mice. It is not related to the human hepatitis viruses A, B, C, D, or E. MHV causes a range of diseases in mice, including hepatitis (liver inflammation), encephalomyelitis (inflammation of the brain and spinal cord), and enteritis (inflammation of the intestine). The virus is transmitted through fecal-oral route and respiratory droplets. It's widely used in research to understand the pathogenesis, immunity, and molecular biology of coronaviruses.

Transmissible gastroenteritis virus (TGEV) is a porcine coronavirus that primarily affects the pig's intestinal tract, causing severe diarrhea, vomiting, and dehydration. The infection is highly contagious and can lead to significant mortality in young piglets. TGEV is transmitted through the fecal-oral route and can also be spread by contaminated fomites or aerosols. It primarily infects enterocytes in the small intestine, leading to villous atrophy and malabsorption of nutrients. There are no specific antiviral treatments for TGEV infection, and control measures typically focus on biosecurity, vaccination, and preventing the spread of the virus between herds.

Infectious Bronchitis Virus (IBV) is a single-stranded, enveloped RNA virus belonging to the genus Gammacoronavirus and family Coronaviridae. It is the causative agent of infectious bronchitis (IB), a highly contagious respiratory disease in birds, particularly in chickens. The virus primarily affects the upper respiratory tract, causing tracheitis, bronchitis, and sinusitis. In addition to respiratory issues, IBV can also lead to decreased egg production, poor growth rates, and impaired immune response in infected birds. Several serotypes and variants of IBV exist worldwide, making vaccine development and disease control challenging.
