Set Up

Many systems are available for the isolation of anaerobic bacteria from clinical specimens. The jar system is the oldest and more adapted while the pouches are not popular with many investigators. The anaerobic chambers are expensive to maintain and technically inflexible. This study evaluated the efficacy of the Oxoid anaerobic jar and the GENbag pouches as anaerobic incubation systems. Anaerobic cultures were set up for 145 middle ear exudates and incubation was in the anaerobic jar, GENbag or a combination of both. The effect of specimen transport system and time lapse before culturing on the performance of the anaerobic systems were evaluated Ten genera of anaerobic bacteria were isolated with both systems (P > 0.05). Peptostreptococcus and Prevotella were isolated more frequently in Oxoid jar than in GENbag (P < 0.05) but both systems were not discriminatory for Clostridium, Propionibacterium and Veillonella. The use of GENbag as a backup to Oxoid jar increased isolation rate from 56.6% to 90.3% (P > 0.05). Type of transport media or vehicle did not affect the recovery of anaerobes adversely as did delay in processing of specimen. A careful application of a number of variables may improve isolation of anaerobes from clinical specimens

Active Transport System

The plasma membranes of most animal cells contain transport proteins which function to provide passageways for the transported species across essentially impermeable lipid bilayers. The channel is a passive transport system which allows the movement of ions and low molecular weight molecules along their concentration gradients. The pump is an active transport system and can translocate cations against their natural concentration gradients. The actions and interplay of these two kinds of transport proteins control crucial cell functions such as active transport, excitability and cell communication. In this paper, we will describe and compare several features of the molecular organization of pumps and channels. As an example of an active transport system, we will discuss the structure of the sodium and potassium ion-activated triphosphatase [(Na+ +K+)-ATPase] and as an example of a passive transport system, the communicating channel of gap junctions and lens junctions.
