- Bacterial or Viral Infections of the Respiratory Tract. Viral illnesses are the most common cause of upper respiratory symptoms. Symptoms of a viral illness often appear over several hours without prior illness.Common viral illnesses include colds and the flu (influenza). Bacterial respiratory tract infections are less common than viral infections.he most common sites of bacterial infections in the upper respiratory system are the sinuses and throat. Pneumonia is the most common bacterial infection of the lower respiratory system.

Test Center Respiratory Virus PCR Panel I. Among the most common viruses causing LRIs such as tracheobronchitis, bronchiolitis, and pneumonia are influenza virus, RSV, parainfluenza virus, and adenovirus. Young children, the elderly, and patients with compromised cardiac, pulmonary, or immune systems are at greatest risk for serious disease.

Upper Respiratory Infection in Dogs The most common causes of canine upper respiratory tract infections are bacteria and viruses. These pathogens are highly contagious, especially when dogs get together in high-density situations such as pet stores and animal shelters, and even more so when those areas are not kept clean.pper Respiratory Tract Infections in Dogs Q&A Challenge. A dog with an upper respiratory infection can be easily treated if the disorder is diagnosed sooner than later. True or False. True: The earlier an upper respiratory infection can be diagnosed & treated, the easier and less severe the infection will become.

Anaerobic Infections Infections caused by anaerobic bacteria are common, and may be serious and life-threatening. Anaerobes predominant in the bacterial flora of normal human skin and mucous membranes, and are a common cause of bacterial infections of endogenous origin. Infections due to anaerobes can evolve all body systems and sites.The predominate ones include: abdominal, pelvic, respiratory, and skin and soft tissues infections. Because of their fastidious nature, they are difficult to isolate and are often overlooked.reatment of anaerobic bacterial infection is complicated by the slow growth of these organisms, which makes diagnosis in the laboratory only possible after several days, by their often polymicrobial nature and by the growing resistance of anaerobic bacteria to antimicrobial agents.

Overview of Viral Infections Other viral respiratory infections include influenza and pneumonia. In small children, viruses also commonly cause croup (which is inflammation of the upper and lower airways, called laryngotracheobronchitis) or lower airways (bronchiolitis—see Bronchiolitis).iruses usually infect one particular type of cell. For example, common cold viruses infect only cells of the upper respiratory tract. Additionally, most viruses infect only a few species of plants or animals. Some infect only people.

- The term, upper respiratory infection, often refers to a head cold or the common cold. However, a broader definition of an upper respiratory infection, or URI, is any infection of the upper parts of the respiratory tract, including the nasal passages, nasal sinuses, and throat.

Upper Respiratory Infection in Dogs Upper respiratory infections in dogs are due to bacterial, viral or parasitic infection. Common bacterial agents include Bordetella bronchiseptica, Klebsiella, Streptococcus and Pseudomonas. Viral causes include canine distemper, adenovirus, parainfluenza virus, corona virus, herpes virus and influenza virus.ymptoms of an upper respiratory infection include coughing, sneezing, runny eyes, nasal discharge and blood or mucus in the stool. Coughing in dogs is often mistaken for vomiting or gagging. A cough can be dry and hacking or productive and producing a foamy mucus. Symptoms typically last for seven to 14 days.

RESPIRATORY AIRWAY INFECTIONS The most common cause of bronchiolitis is respiratory syncytial virus; other causes include human metapneumovirus, parainfluenza viruses, and adenoviruses. Manifestations . Early symptoms of bronchiolitis are similar to symptoms of a viral upper respiratory tract infection and include mild rhinorrhea, cough, and sometimes a low-grade fever.

RESPIRATORY AIRWAY INFECTIONS RESPIRATORY AIRWAY INFECTIONS. 1  Acute bronchitis usually occurs after a previous upper respiratory tract infection with extension of the infection to the bronchial tree. 2  It is most common in the winter months, similar to most other respiratory diseases. 3  Air pollution increases the number of cases of bronchitis.

- Abstract. Bacteria are a common cause of both upper and lower respiratory tract infections. An understanding of the classification, likely pathogens, clinical presentation and investigation is needed to plan the logical management of patients.

Are starfish really fish? Sea stars, commonly called, starfish, are not fish. There are approximately 2,000 species of sea star, all of which live in marine waters. Sea stars live underwater, but that is where their resemblance to fish ends.

Bacterial respiratory tract infections are less common than viral infections.neumonia is the most common bacterial infection of the lower respiratory system. Antibiotics are effective against bacterial infections only after they have developed, so most doctors do not prescribe them until a bacterial infection is suspected or confirmed.

Globally, more than 1.5million deaths annually from respiratory infections are attributable to theenvironment (see Table A2.3).ther estimates of theenvironmental attributable fraction came from the CRA (WHO, 2002). Wereport the results for each disease or disease group in the following sections. Indoor and outdoor air quality are two of the main environmental factorsof concern for acute lower respiratory infections.
