Pathologic and clinicopathologic changes were examined in broiler chickens inoculated with Cryptosporidium baileyi (Cb) alone or in combination with infectious bronchitis virus (IBV), infectious bursal disease virus (IBDV) or Escherichia coli (Ec). Concurrent infections with Cb and either IBV or Ec resulted in a greater respiratory inflammatory response than either agent given alone. Concurrent Cb, IBV or Ec infections resulted in a decreased density of respiratory cryptosporidial stages. No interactions between Cb and IBDV were observed. Clinicopathologic results in broiler chicks exhibiting signs of respiratory cryptosporidiosis indicated that pO2 decreased, pCO2 increased, HCO3 increased and CO2 increased. Changes in blood gases and serum electrolyte values correlated with signs of acute respiratory disease. Blood gases and serum electrolyte values were unchanged in birds with bursal and cloacal infections only. Results of these studies clarified pathogenetic events associated with avian respiratory cryptosporidiosis, and demonstrated that cryptosporidiosis may enhance the severity of respiratory disease caused by other avian pathogens.

A 23-year-old woman was supposed to undergo thoracoscopic surgery for the 10th pneumothorax that accompanied histiocytosis X. The past history included Lylle's disease, asthma, myocarditis, drug-induced leucocytopenia and bronchitis obliterans. The preoperative arterial blood gas analysis under receiving O2 at rate of 2 l.min-1 via a nasal cannula revealed normal values. General anesthesia and intubation with a double-lumen endotracheal tube would have been preferable, but regional anesthesia was chosen because of her medical history and positive results of the skin tests for vecuronium, pancronium, diazepam and midazolam. During the first 10 min of thoracoscopic procedure, her respiration became rapid and shallow and she was restless and comatose. The operation was cancelled. Arterial blood gas analysis under receiving O2 at rate of 4 l.min-1 via a face mask revealed: pH 7.025, PaO2 113.8 mmHg, PaO2 244.8 mmHg, HCO3- 29.7 mEq.l-1, BE-5.6, and O2 saturation 99.1%. Manual artificial ventilation with a mask and bag was initiated. Her spontaneous respiration and consciousness recovered in next 30 min. The postoperative course was uneventful. Tachypnea, caused from anxiety, dyspnea and stimulation of irritant receptors in the airway, were considered to be responsible for the event. The duration of inspiration became shorter as tachypnea developed, that made the tidal volume to decrease and hypercapnea ensued.

Chlamydophila pneumoniae is an obligate intracellular bacterium that causes bronchitis, pharyngitis, and pneumonia and may be involved in atherogenesis and Alzheimer's disease. Genome sequencing has identified three eukaryote-type serine/threonine protein kinases, Pkn1, Pkn5, and PknD, that may be important signaling molecules in Chlamydia. Full-length PknD was cloned and expressed as a histidine-tagged protein in Escherichia coli. Differential centrifugation followed by sodium carbonate treatment of E. coli membranes demonstrated that His-PknD is an integral membrane protein. Fusions of overlapping PknD fragments to alkaline phosphatase revealed that PknD contains a single transmembrane domain and that the kinase domain is in the cytoplasm. To facilitate solubility, the kinase domain was cloned and expressed as a glutathione S-transferase (GST) fusion protein in E. coli. Purified GST-PknD kinase domain autophosphorylated, and catalytic mutants (K33G, D156G, and K33G-D156G mutants) and activation loop mutants (T185A and T193A) were inactive. PknD phosphorylated recombinant Cpn0712, a type III secretion YscD homolog that has two forkhead-associated domains. Thin-layer chromatography revealed that the PknD kinase domain autophosphorylated on threonine and tyrosine and phosphorylated the FHA-2 domain of Cpn0712 on serine and tyrosine. To our knowledge, this is the first demonstration of a bacterial protein kinase with amino acid specificity for both serine/threonine and tyrosine residues and this is the first study to show phosphorylation of a predicted type III secretion structural protein.
