The objective of this study was to determine the benefit of pre-milking teat foam disinfection on the prevention of new infections by contagious and environmental bacteria in two spring calving herds managed outdoors (Herd 1 [H1]; 331 cows and Herd 2 [H2]; 142 cows). Four pre-milking teat preparation treatments were applied post calving; with each herd receiving two treatments; using a split udder design (for approx. 15 weeks). These treatments included; (1) ‘water wash, foam application and dry wipe (WFD) in H1′; (2) ‘water wash and dry wipe (WD)’ in H1; (3) ‘foam application and dry wipe (FD)’ in H2; (4) ‘no teat cleaning preparation (NP)’ in H2. Individual quarter foremilk samples were collected on four occasions and all clinical and sub-clinical cases were recorded. The mean SCC of quarter foremilk samples was 134 × 103 cells/mL and 127 × 103 cells/mL for WD and WFD, respectively, and 109 × 103 cells/mL and 89 × 103 cells/mL for NP and FD, respectively (p > 0.05). Lower bacterial counts were observed on teat skin that received a foaming treatment. Pre-milking teat disinfection using a foaming product may be of little benefit, in early lactation, for a pasture-based dairy herd.

ABSTRACTAn experiment was performed with two groups of nine British Friesian cows to compare the effect of calving in fat or thin condition on (1) the mobilization and functional activity of subcutaneous adipose tissue, (2) the mobilization of skeletal muscle, (3) the development and resolution of fatty infiltration of the liver and (4) the chemistry and haematology of blood. Sampling was performed at various times during the dry period and subsequent lactation. There were no differences between groups in the amount of adipose tissue mobilized between 4 weeks before and 26 weeks after calving. The lipogenic and lipolytic capacities of isolated adipocytes were also not different between groups at any time although major changes occurred in both over the calving period and during early lactation. Acetate oxidation to carbon dioxide was higher in adipocytes isolated from thin cows particularly after calving. More muscle fibre area was lost in the fat cows compared with the thin cows between 4 weeks before and 4 weeks after calving and the fat cows had greater infiltration of fat in the liver at 1 and 4 weeks after calving than the thin cows. The mean white-cell count was lower and the packed-cell volume was higher in the fat cows than in the thin cows at 1 week after calving. The major differences between groups in blood composition were increased concentrations of copper, non-esterified fatty acids, bilirubin and enzymes such as ornithine carbamyl transferase in the fat cows after calving. These results suggest that fat and thin cows respond differently to the metabolic demands of early lactation and that some of these differences render fat cows more susceptible to disease.

Salmonella typhi was isolated from 369 andSalmonella paratyphi A was isolated from 6 of 515 Vietnamese patients with suspected enteric fever. Compared with conventional broth culture of blood, direct plating of the buffy coat had a diagnostic sensitivity of 99.5% (95% confidence interval [CI], 97.1 to 100%). Blood bacterial counts were estimated by the pour plate method. The median S. typhi count in blood was 1 CFU/ml (range, <0.3 to 387 CFU/ml), of which a mean of 63% (95% CI, 58 to 67%) were intracellular. The mean number of bacteria per infected leukocyte was 1.3 (interquartile range [IQR], 0.7 to 2.4) CFU/cell (n = 81). Children (<15 years old;n = 115) had higher median blood bacterial counts than adults (n = 262): 1.5 (range, <0.3 to 387) versus 0.6 (range, <0.3 to 17.7) CFU/ml (P = 0.008), and patients who excreted S. typhi in feces had higher bacteremias than those who did not: a median of 3 (range, <0.3 to 32) versus 1 (range, <0.3 to 68) CFU/ml (P = 0.02). Blood bacterial counts declined with increasing duration of illness (P = 0.002) and were higher in infections caused by multidrug-resistant S. typhi (1.3 [range, <0.3 to 387] CFU/ml; n = 313) than in infections caused by antibiotic-sensitive S. typhi (0.5 [range, <0.3 to 32] CFU/ml; n = 62) (P = 0.006). In a multivariate analysis this proved to be an independent association, suggesting a relationship between antibiotic resistance and virulence in S. typhi.

The applanation transducer was used to measure intracranial pressure (ICP) through the intact fontanel. The method is painless, rapid, and accurate. The pressures recorded with this fontogram were correlated with direct measurements of ICP. The correlation coefficient of the 21 paired determinations was .98—a very good correlation. Fontanel pressure was determined in 35 normal newborn infants. The mean pressure was 7.37 mm Hg with an SD of ± 1.45 (range, 3.5 to 9.5 mm Hg). Three clinical cases are presented to illustrate the usefulness of this apparatus in the detection of increased ICP and in monitoring the effectiveness of treatment.

ABSTRACT Background: Reconstruction of the popliteal region has limited option in terms of muscle flaps or myocutaneous flaps. Gastrocnemius muscle or the myocutaneous flaps are the option for majority of cases. However, reach of Gastrocnemius is limited if the wound is on the distal one-third thigh or the lateral aspect of knee region. Similarly, if the wound injures the muscle, then coverage becomes all the more difficult. Although inferiorly based fasciocutaneous flaps can cover the wound in case of bony injuries, muscle flaps are beneficial as they help in fracture healing. However, in cases with direct gastrocnemius muscle injury or if the wound on the distal one-third thigh or the lateral aspect then the options of muscle flaps is limited. An inferiorly based sartorius muscle can be one suitable alternative to cover this region. Aims and Objective: The aim is to devise an inferiorly based sartorius muscle flap for coverage of lower thigh, popliteal and upper one-third leg region. Objectives: (1) To identify the location of distal major (largest diameter) pedicle in cadavers and its clinical application. (2) To determine the arc of rotation with distal major pedicle as pivot point. Methods: Ten Cadavers and 20 sartorius muscle dissected out. Prior silicone injection onto the femoral vessels was done to identify the location of the perforators for the sartorius muscle. The distance of perforators from anterior superior iliac spine (ASIS) measured and the diameter of each perforator by transverse cut measured using callipers. In clinical cases, the arc of rotation was measured by keeping the distal perforator intact as pedicle (detaching the muscle from the ASIS without detaching from the insertion and then rotating it). Results: Out of the 10 cadavers analysed, 6 were male and 4 were female. The mean location of the distal major pedicle was at 35.25 cm from ASIS and range was between 30.4 cm to 38.3 cm. There was no significant variation between right and left limbs in individual cadaver (range 0.2 cm–1.6 cm). The mean diameter of the arterial component of distal major pedicle was 1.54 mm. In three clinical cases where this flap was harvested the arc of rotation were 95°, 110°, 125°. In one of the cases where flap was used to cover the tibial plateau (arc of rotation 155°), distal end of the muscle necrosed. Conclusion: This cadaver study supported by various other studies show that it has sizeable distal pedicle based on which whole muscle can be harvested as flap. In our study, the usual location of this pedicle is at 35 cm from ASIS. The mean diameter of the widest pedicle in distal one-third was 1.54 mm which along with other small diameter pedicle can support the entire muscle. This flap reached up to the infrapatellar region without any vascular compromise.

Autopsies of exhumed bodies pose a risk of infections with environmental bacteria or fungi, which may be life-threatening. Thus, it is important to use effective methods of disinfection in forensic pathology facilities. In this study, we investigated the effectiveness of no-touch automated disinfection (NTD) system after autopsies of exhumed bodies. Directly after 11 autopsies of exhumed bodies, we used an NTD system based on a peroxone vapor to disinfect the air and surfaces. We measured microbial burden in the air and on surfaces before and after NTD. The NTD system reduced the mean bacterial burden in the air from 171 colony forming units (CFU)/m3 to 3CFU/m3. The mean fungal burden in the air decreased from 221 CFU/m3 to 9CFU/m3. The mean all-surface microbial burden was 79 CFU/100 cm2 after all autopsies, and it decreased to 2 CFU/100 cm2 after NTD. In conclusion, the peroxone-based NTD system was effective for decontamination of the air and surfaces in a dissecting room after autopsies of exhumed bodies.

ABSTRACTOne hundred and thirty-nine Scottish Half bred ewes were studied during the last 8 weeks of pregnancy, through parturition and early lactation. They were divided, on the basis of their metabolizable energy intake during this period, into low (483 MJ/ewe; L), medium (742 MJ/ewe; M) or high (974 MJ/ewe; H) feeding groups.Ewe weight change (from mating to 12 h post lambing) was directly related to nutritional level and the number of lambs born, e.g. L ewes with triplets lost a mean 13·8 kg, while H ewes with single lambs gained 14·3 kg.Lamb birth weight and perinatal lamb mortality levels were affected by ewe nutrition and litter size. L twins weighed 19% less at birth than H twins; L triplets weighed 26% less than H triplets. The mortality rate of L twins was 23% greater than M twins; L triplets exceeded the H triplet mortality rate by 87%.Ewe energy feeding during late pregnancy affected the mean daily weight gain of lambs for at least 3 weeks after birth. H single, twin and triplet lambs grew 12%, 15% and 16% faster than M lambs and 19%, 31 % and 31 % faster than L lambs respectively.The H group produced 33 % more lamb live weight at 3 weeks of age for every lamb born than did the L group.Lamb serum immunoglobulin levels were related to litter size but did not reflect the differences in ewe feeding during late pregnancy.

Stocking Rates

A study was made during a three year period (1 968-1 970) of wool production by a flock of 540 ewes grazing annual pasture at Werribee, Victoria. The ewes were stocked at three rates (5, 7 1/2 and 10 ewes ha-1) and lambed between July 6 and August 20 or between September 10 and October 29 each year. Fibre diameter and length of wool samples were measured in 1968, 1969 and 1970 ; in 1970 growth of greasy wool was calculated from staples of dye-banded wool. Wool growth was reduced in all ewes during late pregnancy and early lactation but was not affected during late lactation in ewes lambing in September. The proportion of tender fleeces from all ewes was greater in 1970 and the weight of fleeces from only those ewes bearing single lambs was less in all years for ewes lambing in July than for ewes lambing in September. More ewes were barren and fewer ewes had twins in July and consequently the mean fleece weights of all ewes from both groups were similar. Fleeces from ewes stocked at 10 ha-1 were lighter, shorter and finer than fleeces from ewes stocked at 5 and 7 1/2 ha-1, but the proportion of tender fleeces did not differ between the groups. Wool production of ewes stocked at 5 and 7 1/2 ha-1 increased from 1968 to 1970, whereas that of ewes at 10 ha-1 did not. This was associated with differences in pasture availability and composition. At 10 ewes ha-1 less pasture was present in winter and spring in 1970 than in 1968, whereas at the other stocking rates it was greater. In 1970 the density of weeds in autumn was greater and in spring more silver grass (Vulpia spp.) and less brome grass (Bromus spp.) was available at the high stocking rate.

SUMMARYSalmonella typhimurium 49a infection in a large dairy herd persisted for 3·5 years. Illness initially occurred in cows and calves but latterly although there were fewer clinical cases milk filters were culturally positive on 26 out of 73 samplings. Three associated human disease incidents occurred. Individual milk samples identified one cow as an excreter and the organism was recovered from the mammary gland of this animal at slaughter. Correlation between calving pattern, the times of calving and the occurrence of positive milk filters suggest that the cow may have been excreting the organism intermittently from the udder for 2·5 years.

SUMMARYRecords of milking rate, milk yield and milk composition were collected over 12 yr from 123 Ayrshire heifers in their first lactation in one herd. Three direct measures of milking rate, i.e. peak flow rate, machine rate and overall rate were closely correlated and each was also correlated with total lactation yield of milk. Milking rate accounted for only a very small part of the variation in fat and total solids percentages. The mean yield of milk per milking in early lactation was a better predictor of total lactation yield than was milking rate but, among animals giving the same early lactation yield of milk, the faster milkers gave higher lactation yields than the slower milkers.

Feeding Systems

A group of 36 Holstein-Friesian cows in a commercial dairy herd were used to test the effects on milk yield and composition of feeding 0.5 kg/day of a rumen-inert fat supplement containing long-chain fatty acids, given in addition to their normal ration. The group was divided into early and mid lactation cows, and the effect of the supplement was evaluated over a 12-week period of grazing predominantly kikuyu (Pennisetum clandestinum) pastures. There was a non-significant (P>0.05) trend to increased milk yield for cows in mid lactation (9% or 2.8 kg milk/kg fat supplement), no response in early lactation, and an overall response of 0.8 kg milk/kg fat supplement for all cows. There was no effect (P>0.05) of fat supplement on milk components. The lack of a milk response in the early lactation group is discussed in relation to the protein content of the diet and changes in liveweight. The varied responses with stage of lactation mean that feeding systems that can easily differentiate stages of lactation for cows would be required in dairies.
