In order to investigate the prevalence of Mannheimia haemolytica infection in cattle, nasal andnasopharyngeal swabs and blood samples were obtained from 250 cattle after slaughter at Ahvaz(southwestern Iran) abattoir. Nasal and nasopharyngeal swabs were cultured on blood agar and incubated at37°C for 24-48 h. The suspected bacterial cultures were processed for isolation of M. haemolytica follow...

To evaluate our experience with fungal burn wound infection, we performed a 10-year review for comparison with our experience with bacterial burn wound infection. During the study period, a marked decline occurred in bacterial wound infection but not in fungal wound infection. Patients with either bacterial or fungal burn wound infection had massive injury, with burn size averaging greater than...

Since 1940 when we began a study of sensitization in laboratory animals treated with pertussis vaccine we have emphasized the role of the bacterial protein in this phenomenon. Considerable information has been accumulated which indicates that vaccination with Hemnophilus pertussis, while increasing resistance against infection by the same organism will, at the same time, produce hypersensitivit...

OBJECTIVE To discuss application values of serum procalcitonin (PCT), C-reactive protein (CRP) and white blood cells (WBC) count in early diagnosis and treatment of neonatal bacterial infectious diseases. METHODS Clinical data of one hundred and thirty-six newborns with infectious diseases who were admitted into the hospital were retrospectively analyzed. They were divided into bacterial infe...

One hundred and ninety children with atopic eczema were studied prospectively for two and a half years. The mean period of observation was 13 months. Seventy six children (40%) had between them 164 episodes of exacerbation of eczema due to bacterial infection, and in 52 (32%) infection recurred within three months of a previous infection. Twenty five episodes (15%) led to admission to hospital....

Anaplasma phagocytophilum is an emerging pathogen that causes human granulocytic anaplasmosis. Infection with this zoonotic pathogen affects cell function in both vertebrate host and the tick vector, Ixodes scapularis. Global tissue-specific response and apoptosis signaling pathways were characterized in I. scapularis nymphs and adult female midguts and salivary glands infected with A. phagocyt...

A new cytochemical technique, sensitive to altered lysosomal membrane permeability of blood neutrophils, has been evaluated as a screening test for bacterial infection. This technique, for the lysosomal enzymes acid phosphatase and chloroacetate esterase, was compared with the neutrophil alkaline phosphatase and nitroblue tetrazolium tests. The mean score for each method was significantly highe...

An association exists between respiratory viruses and bacterial infections. Prevention or treatment of the preceding viral infection is a logical goal for reducing this important cause of morbidity and mortality. The ability of the novel, selective parainfluenza virus hemagglutinin-neuraminidase inhibitor BCX 2798 to prevent the synergism between a paramyxovirus and Streptococcus pneumoniae was...
