If birds are Feeding Amounts and Frequency weaned onto a specific diet, it is important that a new Younger birds should be fed more often than older, owner continue feeding the same diet until the bird larger birds. Adequate weight gain and good mor- is accustomed to its new surroundings and the diet phologic development are more important indicators can be safely changed. The amount of food and frequency of feed- When the bird is at the right weight and develop- ing depends on the age and development of the chick ment or consuming some solid food, the midday feed- and the particular diet fed. Birds one to five days old ing should be gradually eliminated, followed by the should be fed six to ten times daily; chicks with eyes morning and then the evening meals. If the bird was closed, four to six times daily; chicks with eyes fed properly to begin with, weight loss in the range of opened, three to four times daily; and birds with 10 to 15% of the peak body weight may be expected feathers emerging, two to three times daily. If the bird was under- less than one week old may benefit from around-the- weight to begin with, any weight loss may be abnor- clock feeding, but it is not necessary to feed older mal.

The crop should be filled include excessive weight loss, slowed crop-emptying to capacity and allowed to nearly empty before the times, depression, diarrhea, regurgitation or simply next meal. If problems are noted, weaning empty at least once each day (usually in the morning should be postponed and the underlying problem following the final night feeding). If the weight loss is severe, it feed young birds the maximum amounts of food early may be necessary to resume hand-feeding two to to stimulate good growth and increase crop capacity. This is especially common in malnour- ished birds that are stunted in growth but of weaning age. It may be necessary to tube-feed these birds, because forcing them to hand-feed increases the risk of aspiration and causes severe stress. Hygiene Careful control of environmental sources of patho- genic bacteria and yeast are essential for maintain- ing healthy chicks. A diligent, thorough, common- sense approach that includes minimum exposure to harmful chemicals works best. The most important sources of microbial contamination include the food, water supply, feeding and food preparation utensils, other birds in the nursery and the hand-feeder. If microbial infections are repeatedly encountered in a nursery, these areas should be cultured in order to identify and eliminate the source of contamination. To avoid these microbes, the compo- of manufactured food when, in fact, the outbreaks were the result nents of the diet should be carefully selected. Most of careless food handling (eg, wet food or food contaminated by rodent droppings) on the part of the aviculturist (courtesy of commercial diets are relatively clean. Yeast and bacterial contamination of any formulated diet can occur if it is improperly stored. Pseudomonas is a frequent con- taminant of water taps and bottled water dispensers. As a guide, the standards for cleanliness in a nursery should be higher than the feeders would maintain for themselves. Opened containers of dry baby formula should be stored in sealed containers in the freezer. Powdered baby formula that has been mixed with water should never be stored and fed to babies in subsequent feedings. A separate syringe should be dry environment, aviculturists must also make certain they do not used for each bird and the syringes should be filled in serve as sources of infection for their neonates. Under no circumstances should a syringe hygiene involves thoroughly washing the hands before handling any neonate. Hands should also be washed when moving from one used to feed a bird be dipped back into the food for a group of neonates to the next. The type of diet, percent solids content, how the periodically removed and scrubbed to avoid a build- diet is prepared, amount and frequency of feed- up of food and pathogens. New Additions Body Weight Charts New additions to the nursery should be placed in One of the most valuable tools for evaluating nestling separate brooders, fed last and monitored carefully birds is a chart recording daily body weight. At most stages of development, juve- potential microbial infections that might spread to nile birds should gain a certain amount of weight other chicks. Failure to gain this amount of weight is cause make certain that the neonates are not shedding for concern. Detecting an infectious agent in a weight gain, and lack of a normal weight gain is often newly introduced chick also indicates that the par- one of the earliest signs of problems.

Evaluating Nestling Birds Nestling psittacine birds can be evaluated in the same way as adult birds.

Numbers inside bars denote patients remaining in cardiac arrest and receiving cardiopulmonary resuscitation. Because a single dose was administered, substantial effects on erythropoi- esis were not anticipated. In fact, haemoglobin and haematocrit in the pres- ent study were not statistically different than controls at 48 h and at 72 h. Cerebral ischaemia is inevitable during cardiac arrest and to some extent during the postre- suscitation period. Evidence shows that the brain remains hypoxic during the ¿rst few hours of recovery from cardiac arrest, but no more than 2 days [33].

Behav Brain Res 153:77–86 Pathophysiology of Resistance 17 amongst Aerobic Gram-negative Bacilli in Particular Acinetobacter Species N. When a patient is critically ill, carriage of normal Àora is eroded and then replaced by abnormal Àora, and the density of growth shifts from low to high grade (gut overgrowth). Normal Àora consists of six potential pathogens: Streptococcus pneumoniae, Haemophilus inÀuenzae, Moraxella catarrhalis (found in the oropharynx only); Escherichia coli (found in the gut) and Staphylococcus aureus and Candida albicans (found in both the oropharynx and gut). High-grade carriage is synonymous with gut over- growth and is the crucial event that precedes endogenous infection. Primary endogenous infection occurs when the caus- ative microorganism is present in the admission Àora; it generally occurs within 1 week of admission. The frequency is 55% and parenteral antimicrobials are the manoeuvre to treat/prevent this type of infection [2]. The manoeuvre to impact this type of infection is enteral antimicrobials and good hygiene [3]. The manoeuvre designed to combat this infection is hygiene and topical antimicrobials [4]. The main mechanism for transmission of potential pathogens including Acinetobacter baumannii is spread via the hands of healthcare workers. Adequate hand hygiene is therefore thought to 17 Pathophysiology of Resistance amongst Aerobic Gram-negative Bacilli 209 be crucial in preventing transmission of A. There is low-level evidence for the efforts to control infection with handwashing [5]. Poor compliance cannot be blamed as the only reason for the failure of handwashing to control infection. Handwashing by healthcare workers on its own does not abolish, but only reduces, transmission, as it is dependent on the bacterial load on the hands. Recent studies using surveillance cultures of throat and rectum have shown that, under ideal circumstances, handwashing can only inÀuence secondary endogenous and exogenous infections (approximately 45% of all in- fections). In many hospitals, alcohol-based hand rubs, consisting of varying concentra- tions of ethyl or isopropyl alcohol, often in combination with chlorhexidine and organic emollients, have found wide-spread acceptance as an alternative to handwashing.
