In this study which was carried out during the years 2000-2001, was aimed to identify the amount of spores of Cladosporium Link ex Fr. and Alternaria Nees ex Fr. in the atmosphere of Edirne city. This study was carried out according to the gravimetric method. Before exposure of the atmospheric particles, the slides smeared with glycerine jelly stained with basic fuchsine and were changed weekly. The number of spores was expressed as spores per square centimeter of microscope cover glass. Spores of Cladosporium spp. and Alternaria spp. were recorded throughout the year in the atmosphere of Edirne. During the two years observations, a total 6318 spores/cm2 belonging to Cladosporium spp. and Alternaria spp. were identified. In total 1223 spores/cm2 belonged to Alternaria spp. and 5095 spores/cm2 belonged to Cladosporium spp.. Maximum spores were encountered in July.

In this study, effects of two antimicrobial applications (ozone and chlorine) on broiler carcasses after evisceration were investigated. The ozone and chlorine (sodium hypochlorite, NaHClO) were applied to broiler carcasses as 1.5 ppm and 30 ppm for 7 minutes, respectively. During the broiler processing, the samples were taken from 14 different points in the production line, 17 surface points and 5 workers’ hands for the microbiological analyses as ten replicates. At the beginning, Escherichia coli growth was not observed after ozone treatment. But, E. coli growth increased after portioning and grading of broiler carcasses. It is assumed that workers’ hands and equipment can be a source of secondary contamination. Ozone can also be used in lower concentration and more safely than the chlorine.
The first isolation of Brucella melitensis from bovine aborted fetus in Turkey
(Uludağ Üniversitesi, 2007-12-01) Büyükcangaz, Esra; Şen, Ayşin; Uludağ Üniversitesi/Veteriner Fakültesi/Mikrobiyoloji Bölümü.
Between 2004 and 2005 in Marmara region, Turkey, 41 abortion cases from cattle was investigated by standard isolation procedures for determinating possible role of Brucella spp. The isolates from 8 (19.5 %) of 41 bovine abortion cases were identified as Brucella spp. Biotyping revealed that, 7 (87.5 %) isolates were B. abortus biotype 3 and one (12.5 %) was B. melitensis biotype 3. Since the isolation of B. melitensis from an aborted bovine fetus was not substantially reported in Turkey until now, this report may be considered one of the indicative studies.

(Uludağ Üniversitesi, 2007-12-01) Kumral, Nabi Alper; Kovancı, Bahattin; Akbudak, Bülent; Uludağ Üniversitesi/Ziraat Fakültesi/Bitki Koruma Bölümü.; Uludağ Üniversitesi/Ziraat Fakültesi/Bahçe Bitkileri Bölümü.
The olive leaf moth, Palpita unionalis (Hübner), is an important pest on olives, and also feeds on other host plants from the Oleaceae family. In this study, the development, survival and reproduction of P. unionalis were evaluated in the laboratory at 25°C and photoperiod of L:D = 16:8 on three host plants: olive (Olea europea L., cv. Gemlik), ash (Fraxinus angustifolia Vahl.) and jasmine (Jasminum fruticans L.). Olive leaf moth larvae survived on all three host plants. The developmental time of immature stages ranged from 27.52 days on ash leaves to 30.00 days on olive leaves. Immature survival from egg to pupa was 72% on jasmine, 73% on olive and 74% on ash. The average number of eggs oviposited by adults from larvae reared on ash, jasmine and olive were 194.7, 321.8 and 390.3, respectively. The net reproductive rate of this species varied from 129.8 females/female on ash to 298.3 on olive. The intrinsic rate of population increase on ash, jasmine and olive was 0.148, 0.149 and 0.163 females/female/day, respectively. Palpita unionalis can complete its life cycle on all host plants, but ash was relatively less suitable because of the lower reproductive rate of the insects reared on it.

(Uludağ Üniversitesi, 2007-12-01) İpek, Aydın; Dikmen, Bilgehan Yılmaz; Uludağ Üniversitesi/Ziraat Fakültesi/Zootekni Bölümü.; Uludağ Üniversitesi/Keles Meslek Yüksekokulu/Hayvan Sağlığı ve Yetiştiriciliği Bölümü.
The research was conducted to determine relationship between growth traits and egg weight in Pheasants (Phasianus colchicus). Pheasant eggs were separated into 3 weight groups. The eggs were classified as light (27.8-29.7g), medium (29.8-31.7g), heavy (31.8- 33.7g) weight. Eggs were incubated at 36.5 °C and 90 % relative humidity for 21 days during at which they were rotated hourly at an angle of 45°. Thereafter; these eggs were transferred into hatching machine during the last three days. A temperature of 36.0°C and relative humidity of 95 % were provided for the eggs at hatching period. Chicks at hatching were placed in separated pens as male and female mixed for each egg weight group. The effect of egg weight on chick weight at hatching, mean live weight, weight gain, feed consumption and feed efficiency were found significant (P<0.01). The effect of egg weight on mortality was not significant. The chick weight at hatching in light, medium and heavy egg groups were determined as 19.5, 21.8 and 22.6 g, respectively. In the egg weight X sex groups the mean live weights were determined as 940.2, 1020.5, 1091.2 g for males and 705.6, 739. 4, 778.6 g for females, respectively at 16th wks of age. In the groups the mean feed consumption and feed efficiency were found 4200.6, 4600.8, 5080.1 g and 5.1, 5.2, 5.4 kg, respectively, at 16th wks of age mixed male and female pheasant.

The lichen flora of the Quercus vulcanica forests in Isparta was studied and 92 species belonging to 43 genera were found. 55 lichen taxa are new records for the Isparta province and 2 taxa, Ochrolechia alboflavescens and Collema fasciculare are new records for Turkey.
Some parameters in relation to iron nutrition status of peach orchards
(Uludağ Üniversitesi, 2007-12-01) Çelik, Hakan; Katkat, A. Vahap; Uludağ Üniversitesi/Ziraat Fakültesi/Toprak Bilimi ve Bitki Besleme Bölümü.
This study was conducted to determine DTPA extractable iron contents and some soil properties of peach (Prunus persica L.) orchards, total and 1N HCl extractable iron contents of leaves and investigate their relations with chlorosis. For this purpose, nine peach orchards, each of which included green, slightly chlorotic and severe chlorotic peach trees, were selected. Soil and leaf samples were taken from these orchards for chemical analysis. Soil samples were collected from the top 30 cm and from a 30-60 cm depth from the soils under the peach trees variously affected by iron induced chlorosis. Soil analysis revealed that results, in the top 30 cm, soil extractable iron contents were negatively correlated with pH, EC and lime (r= -0.260*, -0.621** and -0.298**) respectively. Negatively significant correlations between extractable iron and exchangeable cations, were also found, but correlations were positively significant with organic matter at both soil depths (r=0.595**, 0.608**). Most of the DTPA extractable soil iron contents were found higher than the critical concentration range (4.5 mg kg-1) despite visually and analytically iron chlorosis determined in the plants. DTPA method is not capable of estimating and monitoring of iron chlorosis in the plants grown on calcareous soils. 1 N HCl extractable active iron contents of the leaves were found relevant with the chlorosis degrees (r= -0.839**) and recognized as a better nutritional iron indicator than total iron.

(Uludağ Üniversitesi, 2007-12-01) Özkan, Tanju Başarır; Durmaz, Neslihan; Erdemir, Gülin; İlçöl, Yeşim Özarda; Uludağ Üniversitesi/Tıp Fakültesi/Pediatri Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Biyokimya Anabilim Dalı.
Breast milk has unique properties; one is the variability of the compounds in ratio according to the baby’s needs for every lactation period. Iron and zinc are essential elements for life. The aim of this study is to determine Fe and Zn levels in plasma and breast milk of mothers through the first 4 months after delivery and to evaluate its relation with infants’ growth and immune system functions. The study conducted through January 2000 – April 2001 in Bursa with 27 mother-infant couples. The babies grouped into two: Group 1 (n: 16) was formed by the breast milk fed babies, and Group 2 (n: 11) included the babies fed with both breast milk and formula. Besides clinical assessment of the babies, laboratory evaluations were performed on the sera of couples and breast milk. While the comparison of Zn level in colostrum with mature and late mature breast milk demonstrated a statistical significance (p<0.05), Fe had a similar trend without significance. Fe deficiency anemia was found in high percentages in both groups; 32.5% of Group1 and 27.7% of Group2 (p>0.05). Our study affirms the suggestion for Fe supplementation for healthy, term infants beginning from 4th month regardless of nutritional model.
