Pathology and immunohistochemical evaluation of lungs of cattle slaughtered at metropolitan abattoirs in Nigeria and Ghana. J Immunoassay Immunochem. 2020 Feb 23;:1-14 Authors: Ola OO, Adeniran GA, Opoku-Agyemang T, Bediako E, Ishola O, Jarikre TA, Emikpe BO Abstract There was a dearth of information on pathology and causal agents of bovine pneumonia in West Africa. This cross-sectional study conducted at four major metropolitan abattoirs in Nigeria and Ghana was to evaluate the pathology and to immunohistochemically demonstrates viral and bacterial pathogens of bovine pneumonia in West Africa. Out of the 20,605 cattle lungs examined at post-mortem using standard inspection procedures, 136 samples grossly showed pneumonic lesions and 99 randomly selected lung samples were fixed in 10% neutral buffered formalin for histopathological and immunohistochemical examination. The overall prevalence of pneumonia was 0.66%, with 0.72% prevalence in Ibadan, Nigeria and 9.68% prevalence in Ghana. Age and breed were observed to be among the predisposing factors to pneumonia in cattle. Histologically, bronchopneumonia (0.65%), broncho-interstitial pneumonia (0.13%), and interstitial pneumonia (0.08%) were the prominent type of pneumonias observed. Immunohistochemically, 0.8% was positive for bovine PI-3, 0.9% for bovine RSV, 1.0% for Mannheimia haemolytica (MH), and 0.6% for Pasteurella multocida (PM). There were a few interactions of pathogens: PI3 and MH (0.01%), RSV...

This article reviews the spectrum of activity, the main pharmacokinetic and pharmacodynamic characteristics and the clinical efficacy and safety of ceftolozane-tazobactam in the treatment of HAP/VAP in adult patients.Expert opinion: The results of a randomized clinical trial have demonstrated an efficacy and safety profile of ceftolozane-tazobactam similar to that of its comparator for the treatment of patients with HAP/VAP. Several retrospective studies have shown good efficacy of the drug for the treatment of respiratory infections caused by MDR P. aeruginosa. The use of this drug may be incorporated as a new therapeutic...
