Recurrent infections are a consequence of a series of genetic diseases characterized by deficiency in the immunological response. One of these diseases is the agammaglobulinemia, which is characterized by the basic defect in the maturation of lymphocytes B. The carrier of this kind of immunodeficiency, which is linked to the X (XLA) chromosome, has had primary pneumonias that have evolved into ...

A previously fit man developed psittacosis with marked cerebellar symptoms and signs. He was febrile but not confused, and he responded rapidly to treatment with erythromycin. Even if respiratory symptoms are minimal, psittacosis and other atypical pneumonias should be considered in any patient presenting with fever and cerebellar involvement.

Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...

Diffuse interstitial lung disease (ILD) is a general term encompassing a broad range of largely unrelated conditions which share the propensity to cause breathlessness and/or cough, while resulting in bilateral abnormal opacities of various types on conventional chest radiographs or computed tomography (CT) scans. The idiopathic interstitial pneumonias are a subset of diffuse ILDs characterized...

OBJECTIVES There are epidemiological studies indicating that exposure to metal fumes is a risk factor for infectious pneumonia. Whether occupational exposure to other agents, such as inorganic dust or chemicals, also increases the risk for infectious pneumonia is not clear. The aim of the present study was to elucidate whether occupational exposure to respiratory pollutants and irritants increa...

Drilling operations of petroleum generate oily wastes. The disposal of a significant amount of oil-based drill muds has caused soil contamination and critical environmental impacts in the last decades.The current study aimed to investigate the potential of microbial remediation for an aged oil-based drilling waste and to monitor the fluctuation in microbial population throughout a ...

We performed a quantitative trait locus (QTL) analysis of epicuticular hydrocarbon variation in 1650 F(2) males from crosses of Baja California and mainland Mexico populations of Drosophila mojavensis cultured on two major host cacti. Principal component (PC) analysis revealed five PCs that accounted for 82% of the total epicuticular hydrocarbon variation. Courtship trials with mainland females...
