Combination of altered PBPs and expression of cloned extended-spectrum beta-lactamases confers cefotaxime resistance in Haemophilus influenzae [PDF]
, 2006 Background: Resistance to β-lactams in Haemophilus influenzae is mostly due to the presence of TEM β-lactamases. β-Lactamase-negative ampicillin resistance (BLNAR) also occurs as a result of PBP3 modifications. BLNAR strains are particularly common in

Isolates of β-lactamase-negative ampicillin-resistant Haemophilus influenzae causing invasive infections in Spain remain susceptible to cefotaxime and imipenem [PDF]
, 2014 OBJECTIVES: The epidemiology of invasive Haemophilus influenzae has changed in recent years. β-Lactamase-negative ampicillin-resistant (BLNAR) invasive isolates have recently been described in Europe but their clinical significance is unclear.

The Japanese journal of antibiotics, 2000 We investigated antibacterial activities of piperacillin (PIPC) for several resistant strains of bacteria isolated from patients with respiratory infections from 1998 to 1999 in comparison with reference drugs and obtained the following results: 1. The majority of methicillin resistant strains of Staphylococcus aureus (MRSA) showed high resistance to ...

Genetic diversity of the ftsI gene in β-lactamase-nonproducing ampicillin-resistant and β-lactamase-producing amoxicillin-/clavulanic acid-resistant nasopharyngeal haemophilus influenzae strains isolated from children in South Korea [PDF]
, 2018 Haemophilus influenzae frequently colonizes the nasopharynx of children and adults, which can lead to a variety of infections. We investigated H. influenzae carriage in the nasopharynx of 360 children, in terms of (1) the prevalence of strains with ...
