On July 10, 2004, staff members at a children's hospital in Texas noted that six infants with pertussis diagnosed by clinical symptoms and confirmed by polymerase chain reaction (PCR) testing had all been born during June 4-16 at the same area general hospital. The infants had symptoms consistent with pertussis, including cough, congestion, cyanosis, emesis, or apnea. Infection-control personnel at the general hospital (general hospital A), children's hospital (children's hospital A), and the county health department investigated and determined that an outbreak of pertussis among 11 newborns at general hospital A had occurred after direct exposure to a health-care worker (HCW) with pertussis. This report describes the outbreak investigation and highlights the importance of following recommendations to administer tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine to HCWs to prevent transmission of pertussis to patients.

Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary pathogen of enzootic pneumonia (EP), a highly prevalent respiratory disease that affects pigs worldwide. Previous studies have demonstrated that M. hyopneumoniae infection can be longer than 185 days; however, the total duration of infection has not been determined yet. Therefore, the objective of this study was to determine the duration of M. hyopneumoniae infection in asymptomatic carriers. To achieve our goal, 60 pigs were inoculated with M. hyopneumoniae strain 232 and the persistence of M. hyopneumoniae in the respiratory tract was assessed by detection of the bacterial DNA in bronchial swabs and the ability of the infected pigs to transmit the pathogen to sentinels. Infection of the inoculated animals was demonstrated by the detection of M. hyopneumoniae DNA in nasal swabs, seroconversion to the bacteria and the onset of dry coughing. Experimentally infected pigs shed M. hyopneumoniae prior to and after the cough was observed. M. hyopneumoniae DNA was detected in 100% of experimentally infected pigs at 94 days post infection (dpi), 61% at 214dpi and 0% at 254dpi. Experimentally infected pigs transmitted the bacteria to sentinels at 80 and 200dpi. Results of this study have demonstrated that M. hyopneumoniae infected pigs can be incubatory as well as convalescent carriers of the pathogen and that convalescent carriers can remain infectious for up to 200 days. Total clearance of M. hyopneumoniae in the group was evidenced, demonstrating that duration of M. hyopneumoniae infection lasts less than 254 days.

The human airways are faced by a mucous membrane that keeps the airways humid and protects them. One of the main factors of this protection system is the secretion that covers the surface of the membrane. Like an escalator, secretion is moved steadily, day and night in order to eliminate germs and pollutants from the airways. Healthy people normally do not notice this transport. Infection of the airways accompanied by cough disturbs the transport. The aim of the therapy should be the reconstitution of the transport, not the unsighted suppression of mucus production. Therefore adequate rheological properties of the secretion are needed as well as the balance of its components. Ambroxol affects this system at several sites.

Measles are a systemic infectious disease caused by a single stranded ribonucleic acid virus (measles virus) from the paramyxovirus family. Typically, the disease is characterized by a two-phase course. After an average incubation period of 8 to 11 days, initial symptoms such as fever, cough, coryza and conjunctivitis appear. Two thirds of the patients shows a white-marked enanthema on the buccal mucosa (Koplik's spots). After disappearance of these symptoms, a second increase of temperature and the typical measles exanthema, a brownish-red maculopapular rash, appear. Infection with measles virus induces transient immunodeficiency that favours the formation of several complications. Some of them, e. g. encephalitic diseases, are severe and associated with a high mortality. Measles are world-wide distributed and belong to the ten most frequent infectious diseases in some less developed countries. The disease is associated with a high mortality in some African and South-East Asian countries, in particular in children aged less than 12 months. Of particular note, measles are the most important cause of blindness in children in population with borderline vitamin A status. In Germany, the number of reported measles cases has been declined dramatically since the introduction of a vaccine more than four decades ago. However, regional outbreaks or small epidemics still occur. Because there is no specific antiviral treatment, therapy of measles is symptomatic and depends on the manifestation of the disease. The most important prevention strategy is immunization with a life-attenuated vaccine that can be applied as monovaccination or in combination with mumps and rubella virus (MMR vaccination) or mumps, rubella and varicella virus (MMRV vaccination).

Systemic toxoplasmosis and concurrent infection with porcine circovirus-2 (PCV-2) was diagnosed in a fattening pig. Clinical examination of the herd showed that up to 30% of the pigs of this weight group suffered from severe respiratory signs including sneezing and coughing, with a mortality rate of up to 5%. Gross necropsy examination revealed severe interstitial pneumonia and generalized lymphadenopathy. On microscopical examination there was necrotizing inflammation of the lung, adrenal glands and lymph nodes, associated with lymphoid depletion, cytoplasmic basophilic botryoid inclusion bodies and protozoal microorganisms. Infection with Toxoplasma gondii was confirmed by immunohistochemistry (IHC). Polymerase chain reaction analysis, in-situ hybridization and IHC confirmed systemic PCV-2 infection. These findings, associated with the respiratory signs and lesions in lymphoid tissues, are characteristic for post-weaning multisystemic wasting syndrome (PMWS). In this case, immunosuppression by PCV-2 may have triggered systemic toxoplasmosis, or immune stimulation caused by coinfection with T. gondii may have caused extensive replication of PCV-2.

Wegener granulomatosis (WG) is a systemic vasculitis classically involving the lungs, kidneys, and upper respiratory tract. Involvement of other sites does occur but is less frequent. Clinically evident cardiac involvement is uncommon. There are only a few cases in the literature with documentation of the histologic appearance of cardiac involvement in WG. We report a case of a previously healthy 37-year-old man who presented with a one-week history of cough and weakness and a one-day history of shortness of breath. At presentation, he was hypoxic and required intubation. Upon hospitalization, he deteriorated rapidly, became bradycardic and expired the same night. Infection was suspected clinically as the cause of illness and death. At autopsy, the lungs showed diffuse alveolar hemorrhage with capillaritis, diffuse alveolar damage, and parenchymal necrosis with necrotizing granulomas. The heart was enlarged and showed a mixed inflammatory infiltrate composed of neutrophils, eosinophils, and histiocytes, with focal myocyte necrosis. Granulomas, giant cells, and vasculitis were absent. The esophagus showed submucosal vasculitis. A diagnosis of WG was made. Postmortem serology for c-ANCA was positive, and all cultures were negative, confirming the diagnosis. Cardiac involvement is an underrecognized and potentially fatal complication of WG. The histologic findings in the heart may consist of a non-specific inflammatory infiltrate without granulomas or vasculitis, raising a wide differential diagnosis.

Infections with the gram-negative bacteria Bordetella pertussis (B. pertussis) have long been recognized as a significant threat to children and are increasingly recognized as a cause of cough in adolescents and adults. Antibiotic therapy, when administered during the virulent stages of the disease, can reduce the duration and severity of symptoms. Unfortunately, there are no effective treatments for the persistent coughing that accompanies and follows the infection. The pathogenesis of B. pertussis infection is briefly reviewed. Also discussed is the evidence supporting the hypothesis that the inflammatory peptide bradykinin may be responsible for the persistent, paroxysmal coughing associated with B. pertussis-initiated illness.

Infections are one of the most important clinical problem and most frequent cause of interventions among chronically ill children under hospice care. Frequent and long-lasting hospitalizations before admission to the hospice cause patients' colonization with nosocomial pathogens. These pathogens usually cause returning infections, difficult to cure in home care. The aim of the study was evaluation of colonization by multidrug-resistant organisms and infections' frequency in chronically and incurably ill children under care of the Cracow Children's Hospice of Father J. Tischner. We analyzed infections in patients of the Hospice in 2008-2009. Frequency of infections, their localization, pathogens and necessity of hospitalization were evaluated. On the basis of microbiological examination we distinguished infections caused by multidrug resistant pathogens. Ninety microbiological examination were made in 24 children. Urine, stool, pharyngeal and nasal swap and others were examined. Nosocomial pathogens including Gram-negative rods with ESBL phenotype, Gram-positive Enterococci with HLAR phenotype and Staphylococci with MRCNS and MRSA phenotype were isolated in 36 (40%) examinations, in 17 (71%) patients. Frequency of infections was higher in patients colonized by nosocomial pathogens in comparison with patients without colonization, but difference was not statistically important. There are many factors that increase risk of infections and make them difficult to treat, like: immobilization, impaired swallowing and coughing reflexes, thorax deformation, neurogenic bladder, tracheostomy. Multi-drug resistant pathogens are additional risk factor that can lead to the necessity of hospitalization. In chronically and incurably ill patients time of hospitalization should be minimized to reduce the risk of colonization with multi-drug resistant pathogens.

Infections in solid-organ transplant recipients are the most important causes of morbidity and mortality. A primary goal in organ transplant is the prevention or effective treatment of infection, which is the most common life-threatening complication of long-term immunosuppressive therapy. A 21-year-old woman who underwent heart transplant 3 years previous owing to dilated cardiomyopathy was referred to our hospital with symptoms of high fever and cough. The patient's history revealed that she had received a trimethoprim-sulfamethoxazole double-strength tablet each day for prophylactic purposes. On chest radiograph, pneumonia was detected, and in broncho-alveolar lavage sample, Pneumocystis jiroveci cysts were found. After diagnosing P. jiroveci pneumonia, trimethoprim-sulfamethoxazole was initiated at 20 mg/kg/d including intravenous trimethoprim in divided dosages every 6 hours. On the sixth day of therapy, she died in intensive care unit. In solid-organ transplant recipients, although antipneumocystis prophylaxis is recommended within the first 6 to 12 months after transplant, lifelong prophylaxis is also used in several settings. In addition, the physician should keep in mind that P. jiroveci pneumonia may develop in solid organ recipients, despite trimethoprim-sulfamethoxazole prophylaxis.

Infections of domesticated dogs by a worldwide parasitic nematode Filaroides osleri (Oslerus osleri) lead to verminous tracheobronchitis that are often misdiagnosed clinically as kennel cough, due to infection with the bacterium Bordetella bronchiseptica. Diagnosis of two canine cases in Wyoming, USA prompted a search of the literature of canid infections in North America. Infections of domestic dogs are reported in nine US states and four Canadian provinces. Dogs of multiple breeds and both sexes were infected. Most were two years old or younger at diagnosis. Anthelmintic treatments were effective in relieving clinical symptoms, as well as causing resolution of tracheobronchial nodules. Other canid species, including coyotes (Canis latrans) and wolves (Canis lupus), have been infected across North America with a prevalence of 23% and 4%, respectively. Infection with F. osleri should be included in the differential diagnosis of infectious tracheobronchitis of dogs. It can be confirmed most readily by endoscopic detection of distinctive submucosal parasite-filled nodules, combined with histological examination of endoscopic biopsies.
