A SEM study of the aedeagus and spermatheca of Cassida viridis Linnaeus, 1758 (Coleoptera: Chrysomelidae: Cassidinae) from Turkey
It is accepted male genitalia are not diagnostic, but spermathecae are
partly diagnostic within the genus Cassida Linnaeus, 1758 (Coleoptera:
Chrysomelidae: Cassidinae). However, studies on genitalia have been
based only on stereomicroscopic examination. The ultrastructure of
genitalia has mostly not been studied. The aim of this study was to
determine whether this ultrastructures could be diagnostic. Aedeagi and
spermathecae of 63 specimens of Cassida viridis Linnaeus, 1758 were
collected from Qankiri, Hatay, Kayseri, Osmaniye and Zonguldak Provinces
in Turkey in 2003, 2007 and 2015, and examined for the first time. Thus,
new diagnostic characters were obtained and it revealed that it was
diagnostic to either species or subgenus. Photos of aedeagus and
spermatheca taken with both SEM and stereomicroscope are given

IMPACT OF IZBAN ON NEIGHBORHOOD POPULATION CHANGE IN THE IZMIR CITY REGION
This study aims to find out the effects of a suburban railway investment
on population change. Based on this quest, we hypothesize that reliable
and fast rail transit service, which connects main destinations in an
urban region has a significant role in population increase nearby its
stations. In this vein, we use IZBAN Suburban rail as fast rail transit
service in Izmir urban region as case study. Accordingly, population
changes between 2013 and 2018 in the neighborhoods, where there is
direct access to IZBAN stations, are examined in relation to other
neighborhoods by Analysis of Covariance (ANCOVA) statistical models. Two
model groups are devised in the study. Basic Models examine the impact
of IZBAN Neighborhoods considering Izmir sub-regions, i.e., North,
Metropolitan Area and South Sub-Region, while Expanded Models estimate
interaction variables to account for spatial variation in population
changes. We find significant relative increase in the populations of
non-metropolitan neighbourhoods served by IZBAN stations. There is high
variation between different sub-regions and IZBAN sections. Population
increase is higher in the Northern and Southern sub-regions, which leads
us to reach IZBAN-induced decentralization in the metropolitan area.
Although, IZBAN exemplify an incipient transit-oriented development in
Turkey, it falls short of its counterparts in the world. Strategic
planning decisions are needed to support transit-oriented development
around IZBAN stations

Investıgatıon Of Bıocıde And Antıbıotıc Resıstance Profıles In Gram Posıtıve Bacterıa Isolated From Food
Günümüzde hayvan yetiştiriciliğinde gerek hastalıkların tedavisi ve önlenmesi, gerekse
hayvansal gıdaların verimini arttırmak amacıyla antibiyotik ve biyositlerin kullanımının
oldukça yaygın olması ekonomi ve halk sağlığı açısından ciddi sorunlar yaratmaktadır.
Araştırmamızda, Ankara ilinde çeşitli marketlerde satışa sunulan 132 et ve süt ürünü
örneğinden izole edilen 77 Staphylococcus izolatında, antibiyotik ve biyosit direnç
dağılımları ve antibiyotik direnç ve efluks pompa genlerinin varlığı araştırılmıştır. Ayrıca
efluks pompa inhibitörü rezerpinin antimikrobiyal direncine etkisi araştırılmıştır.
Staphylococcus izolatlarında en yüksek oranda direnç tetrasiklin (%24,7)’e karşı
belirlenmiştir. İzole edilen 77 Staphylococcus izolatının 29’u bir veya birden fazla
antibiyotiğe dirençli olarak tespit edilmiştir. Bu izolatların BBL crystal Gram pozitif
tanımlama kiti ve 16S rDNA dizi analizi yöntemleriyle tür bazında tanımlamaları
yapılmıştır. Test edilen biyositlerin hepsine yüksek MİK değerleri gösteren izolatlar
mevcuttur. Rezerpinin Staphylococcus’larda ampisilin duyarlılığını %25, tetrasiklin
duyarlılığını %27,8, triklosan duyarlılığını %20,7, povidon iyodin duyarlılığını %34,5
arttırdığı belirlenmiştir. Çalışılan 29 Staphylococcus izolatında tetK (%88,9), bla (%53,8)
antibiyotik direnç genleri yüksek oranda tespit edilmiştir. Ayrıca efluks pompa genlerinden
acrB (%31), norE (%79,3), sugE (%44,8), smr (%86,2), efrA (%79,3), efrB (%72,4),
mdeA (%82,8), sepA (%51,7) yüksek oranda tespit edilen genlerdir. Araştırmamızda
tüketime sunulan hayvansal gıdalardan izole ettiğimiz Staphylococcus’ların antimikrobiyal
direnç genleri bulundurmaları, bu direnç genlerinin kromozomal ve kromozom dışı genetik
materyallerle patojenlere ve normal flora bakterilerine aktarmaları riski sebebiyle, halk
sağlığı açısından önemli bir tehdit oluşturmaktadır. Efluks pompası kaynaklı
antimikrobiyal direncinin, efluks pompası inhibitörü rezerpin kullanımı ile belli bir oranda
azaltılabileceği fakat bu alanda daha kapsamlı çalışmaların yapılması gerektiği
düşünülmektedirThe widespread use of antibiotics and biocides in animal husbandry, both for the treatment
and prevention of diseases and to increase the yield of animal foods, creates serious
problems in terms of economy and public health. In this study, antibiotic and biocide
resistance profile and antibiotic resistance and efflux pump genes were investigated in 77
Staphylococcus isolated from 132 meat and dairy products sold in various markets in
Ankara. In this study, the effect of efflux pump inhibitor reserpine on antimicrobial
resistance was investigated. The highest resistance was determined against tetracycline
(24.7%) in Staphylococcus isolates. Of the 77 Staphylococcus isolated, 29 were found to
be resistant to one or more antibiotics. These isolates were identified on the basis of
species by BBL crystal Gram positive identification kit and 16S rDNA sequence analysis
methods. Isolates showing high MICs to all of the biocides tested were available.
Reserpine increased ampicillin sensitivity 25%, tetracycline sensitivity 27.8%, triclosan
sensitivity 20.7%, povidone iodine sensitivity 34.5% in Staphylococcus isolates. The
antibiotic resistance genes tetK (88,9%), bla (53,8%) were found to be high in 29
Staphylococcus isolates. Furthermore, among the efflux pump genes acrB (31%), norE
(79.3%), sugE (44.8%), smr (86.2%), efrA (79.3%), efrB (72.4%), mdeA (82.8%), sepA
(51.7%) are highly detected. The presence of antimicrobial resistance genes of
Staphylococcus isolated from foods of animal origin presented in our study is an important
threat to public health due to the risk that these resistance genes are transferred to
pathogens and normal flora bacteria by chromosomal and extrachromosomal genetic
materials. It is thought that animicrobial resistance from efflux pump can be reduced to a
certain extent with the use of efflux pump inhibitor reserpine, but further studies are
needed in this area
