Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden
The
focus
of
this
project
was
to
characterize
the
occurrence
of
ESBL-?producing
bacteria
in
two
irrigation
water
ponds
in
Southern
Sweden.
Samples
were
taken
from
two
ponds
nearby
each
other,
from
which
analyses
were
made
based
on
levels
of
community
and
individual
isolates.
Community
samples
were
used
for
attempts
for
characterization
of
resistance
patterns
in
irrigation
water
using
the
Omnilog
PM-?plate
system.
The
growth
of
community
microbiota
in
the
presence
of
the
following
antibiotic
substances
was
assessed;
amikacin,
gentamicin,
kanamycin,
penicillin
G,
ampicillin,
piperacillin,
trimethoprim,
potassium
tellurite
and
ciprofloxacin.
Isolates
were
pure
cultured
using
semi-?selective
media:
LB,
Rainbow
Agar,
mEnterococcus,
0.1
TSA
and
VRBD.
A
total
of
177
isolates
were
isolated
randomly.
Each
isolate
was
identified
using
the
Omnilog
GENIII-?system
of
biochemical
characterization.
Further,
the
isolates
were
tested
on
Brilliance
ESBL-?agar
for
their
ability
to
grow.
Out
of
the
total
number
of
isolates,
30
were
selected,
preferably
Enterobacteriaceae
or
Pseudomonas
spp.,
based
on
their
high
similarity
to
library
strain
during
the
identification
in
the
Omnilog-?system.
These
were
further
characterized
using
Etest-?sticks.
Three
selected
strains
were
picked
for
further
analyses
using
exogenous
isolation
for
attempts
to
simulate
horizontal
gene
transfer,
and
Omnilog
PM-?panels
containing
various
antibiotics
of
interest.
Selections
of
samples
were
chosen
for
molecular
tests
targeting
plasmid-?borne
resistance
genes
CTX-?M1,
CTX-?M2
and
SHV.
The
method
for
assessing
community-?resistance
patterns
showed
ambiguous
data
that
was
difficult
to
interpret;
further
optimization
is
recommended.
For
all
tested
PM-?plates,
generally
greatest
differences
between
substances
were
found
among
wells
with
the
strongest
concentration
of
antibiotic
substance.
A
total
of
175
isolates
displayed
ability
to
grow
on
ESBL-?agar.
Etests
confirmed
ability
of
isolates
to
resist
many
?-?lactam
antibiotics
and
many
were
clinically
resistant
to
certain
substances.
No
plasmids
were
transferred
during
exogenous
isolation.
During
molecular
tests,
a
few
matches
were
found
for
the
CTX-?M1
gene.
Isolates
analyzed
with
Omnilog
PM-?plates
showed
resistance
to
most
compounds
tested.
The
isolates
showed
greatest
resistance
toward
penicillin
G,
ampicillin,
amikacin,
kanamycin
and
trimethoprim.
In
the
study,
it
was
established
that
resistance
among
bacteria
was
frequently
occurring
in
the
irrigation
water,
and
?-?lactamase
producing
bacteria
was
very
common.
Extended
studies
are
needed
to
assess
the
frequency-?
and
occurrence
of
horizontal
gene
transfer
(HGF)
in
this
environment.
Although
some
potential

data
is
found,
it
is
at
this
point
not
possible
to

The aim of the study was to examine plaqueindex, gingivalindex and oral hygiene measure among patients between 20-26 years of age, who were treated at the Dental Hygienist Programme at the University of Kristianstad. The study was performed as a dental record. All 126 subjects with records in this age were including in the study. Sixteen records (13 %) were excluded because the criteria were not fulfilled. Plauqeindex, gingivalindex and oral hygiene measures were registered from 110 records.
Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening
Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.
Regionala och sociala skillnader i hälsotillstånd : En jämförelsestudie av Danderyd och Rinkeby
Sweden's population holds today one of the highest life expectancies in the world and an increasing number of Swedes believe that they have good health. However, the problem still remains that there exists significant differences in health between different population groups and neighborhoods. Two neighborhoods that demonstrate high inequality in health status are Rinkeby and Danderyd in Stockholm County. The purpose of this study was to examine why health differs between different neighborhoods and how residents experience the area and their health. To answer this purpose a combination of statistical data and qualitative interviews with residents in Danderyd and Rinkeby has been used with an additional literature review. The study showed that the causes of health inequalities between these neighborhoods was primarily concerned with the factors of education, economic conditions, ethnicity, conditions of comfort and companionship and the surrounding residential environment. The population in Danderyd, made up largely of people with high education, good economic conditions and few foreign-born, while the majority of Rinkeby?s population consists of individuals with low education, poor economic conditions and a high proportion of inhabitants of foreign origin, which are determining factors leading to poorer health status among the population.
Ungdomstid, Framtid, Vuxentid : gymnasieungdomars tankar kring utbildning, karriär, vagabonderande och familjebildande
The purpose of this essay was to study how youths think about their youth and future. Our intention was to study in which order of priority today's high school students in Helsingborg ranked family life, education, career and vagabonding. We also investigated what the term adolescence meant to them.Our main questions were how our respondents looked upon their youth and their future. In which way did they give priority to family life, education, career and vagabonding and why did they give these priorities? Which meaning did the respondents lay in the term adolescence?The study was based on interviews with seven young people, studying at a communal high school in Helsingborg.
Utbildningens betydelse för hälsan : En studie i skillnad på ohälsa mellan akademiker och icke-akademiker
The main focus with this study was to investigate if there was a difference in level ofeducation and self-rated health and if it could be explained by the amount of control,demands and social support at work. Theories used in this essay are education, health,and the job strain-model (control, demands and social support at work). We used analready done study by Folkhälsoinstitutet (2004) to examine these questions. Theanalysed sample consists of respondents 12 166 aged 18-84 years. The decline was39, 2 %.
Äh! Vadå nervös? Kör nu bara! : En studie om hur lärare och elever kan arbeta i gymnasieskolan för att lära sig hantera rampfeber
The purpose of our study is to find out how teachers can help their students to learn how to managestage fright. By interviewing high school teachers and high school students and also observe one oftheir classes, we wanted to find out how they think about the causes of stage fright and what youcan do to relieve it. We also wanted to find out how teachers are working to teach students how todeal with stage fright, and how they think that you also could work. As a teacher of music, among other things, the task is to assess and rate the students performancesin music. Several components are based on the students' courage to play on his or her instrument infront of other people.
Kan ät- och liggbås påverka kornas välbefinnande?
The purpose of this literature review was from dairy cows? behaviour and welfare point ofview describe how feed bunk and cubicles in a loose house system should be designed. Todaydairy cows in Sweden and in the world have high demands because of a high milk production,stress and higher risk of being afflicted with diseases. Through selection in breeding the bestquality can be performed, but high demands of the environment for the dairy cow is above allalso important for a good welfare and for a good milk production. Feed bunks and cubiclesare just some parts to be designed in the best way for a good animal welfare.
Social behaviour and time budget of breeding bulls
The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.
Scrum ? en fallstudie från lokala företags perspektiv
Through a case study, I wanted to find out what advantages and disadvantages local companies consider with scrum and what they think about its future. To find out what scrum is, I read the literature and scientific articles and then wrote surveys based on my thoughts. Further, I also wanted to find out if it?s possible to use scrum in a school environment and therefore I visited a high school class who used scrum in one of their projects. The result was good but could have been better as it requires more training of scrum to understand everything.
Genusaspekter på föräldraledighet i svenska små och medelstora företag
The main intention with this study was to explore how parents, employed in three Swedish small- and medium-sized companies, experienced their combination of work and parental leave. The investigation was carried out by a questionnaire, and the 21 participants estimated the attitude from and the treatment by mainly the management and the colleagues. The answers were analyzed both from a perspective of gender and in the aspect of high- and low utilizers of parental leave. The results showed that although both men and women generally estimated the attitude from the management and the colleagues towards parental leave to be positive, the parental leave was divided traditionally and unequally between the parents..

Welcome to Holland ? a study in parent experience, copingstrategies and interaction with school and municipality, of parents to children with Asperger syndrome.
The purpose of the study is to examine, describe and analyse how a selection of parents to children with Asperger syndrome understand, experience and cope with their parenthood. To attain this purpose we focused on these following questions;How does the respondents view their parenthood?; What kind of strategies does the respondents use to cope with their parenthood on the basis on their child with Asperger syndrome?; How does the respondents experience the mesosystem interact with them regarding situations contenting strenuous and stress?We chose to do a qualitative study by conducting separate interviews with eight parents to children with Asperger syndrome. Then we analyzed the answers using an abductive research, we tested the empirical data against our choice of theoretical perspectives. The results shows; that several of the parents in the study have experiences of high strenuous and stress in combination the several roles their parenthood contained.
Låg, medel eller hög kvalitet i förskolan : En studie om hur och varför kvalitèn skiljer sig mellan förskolor
My essay deals with a problem in our society which, in my opinion, has been neglected. Even today in 2011, the quality of schools and preschools is extremely varied. This has been a problem for a long time and not nearly enough attention has been paid to it.In my essay I have tried to understand what it is that causes these differences in quality between preschools. With help from literature and research studies I have examined what quality in preschool really means.My starting point is an account of my own experience at the preschool where I currently work and a description of a study visit I made to another preschool which operates in a very different way to the one where I work. I wanted to investigate what the consequences are for children who grow up attending preschools of different quality.
Utvärdering av miljöbonus IP-lantbruk :
The Dairy business is changing a lot because of some scandals in the agricultural area
for example the BSE crises in Great Britain. Because of the scandals the food industry
and the farm association have created a certifying system; IP-Sigill Swedish standard
system.
We contacted Skånemejerier as they have been successful in the certifying area.
They asked us if we wanted to do a study in the certifying area of dairy farmers. At
Skånemejerier they gave us most of the literature in the area about certifying.
The result of the study, is that we have taken up the most common remark?s. The most
frequent remark is journal over routines in management of dairy cows on daily basis.
Another remark of the study is that the frequency of the remarks decreases with greater
production..
