The prevalence of bacterial isolation and the somatic cell count (SCC) of the milk from goats (n = 110 from six herds) and sheep (n = 153 from three herds) was determined at parturition and approximately 40 days later. Incidence of new intramammary infection (IMI) and the spontaneous cure rate were determined aver this time period. In the goats, 27.3 and 25.5% were infected at parturition and 40 days later, respectively, while 15.0 and 9.1 % of sheep were infected at parturition and 40 days later, respectively. Incidence of new infection was 0.039 and 0.034 cases/half/30 days for goats and sheep, respectively, and did not differ between the species (P > 0.2). Spontaneous cure occurred in 93.8% of sheep halves infected at parturition but only 50.0% of goat halves (P < 0.05). Coagulase negative staphylococci (CNS) were the most common isolates from bath sheep and goals. Milk from bacteriologically positive halves had a significantly higher somatic cell count than halves from which no bacteria were isolated in bath sheep and goats.
It was concluded that bacterial infection of the mammary gland was associated with an elevated somatic cell count. Additionally, differences were detected between the species in incidence of new infection and spontaneous cure rate which resulted in a decline in prevalence in sheep, but not goats, with time postpartum. |

Abstract
Aim: Large tropical trees form the interface between ground and airborne observa?
tions, offering a unique opportunity to capture forest properties remotely and to inves?
tigate their variations on broad scales. However, despite rapid development of metrics
to characterize the forest canopy from remotely sensed data, a gap remains between
aerial and field inventories. To close this gap, we propose a new pan?tropical model to
predict plot?level forest structure properties and biomass from only the largest trees.
Location: Pan?tropical.
Time period: Early 21st century.
Major taxa studied: Woody plants.
Methods: Using a dataset of 867 plots distributed among 118 sites across the tropics,
we tested the prediction of the quadratic mean diameter, basal area, Lorey’s height,
community wood density and aboveground biomass (AGB) from the ith largest trees.
Results: Measuring the largest trees in tropical forests enables unbiased predictions of
plot? and site?level forest structure. The 20 largest trees per hectare predicted quad?
ratic mean diameter, basal area, Lorey’s height, community wood density and AGB
with 12, 16, 4, 4 and 17.7% of relative error, respectively. Most of the remaining error
in biomass prediction is driven by differences in the proportion of total biomass held
in medium?sized trees (50–70 cm diameter at breast height), which shows some conti?
nental dependency, with American tropical forests presenting the highest proportion
of total biomass in these intermediate?diameter classes relative to other continents.
Main conclusions: Our approach provides new information on tropical forest struc?
ture and can be used to generate accurate field estimates of tropical forest carbon
stocks to support the calibration and validation of current and forthcoming space
missions. It will reduce the cost of field inventories and contribute to scientific under?
standing of tropical forest ecosystems and response to climate change. MenosAbstract
