Focus: Zoonotic Disease: Retrospective Evaluation of Hydatid Cyst Cases During Pregnancy

Aim: Zoonotic parasite infections affect many pregnant people around the world. Hydatid cystic disease is also a zoonotic disease caused by Echinococcus sp. This study aims to present the maternal-fetal results and clinical treatment of pregnant women diagnosed with liver hydatid cyst (CH). This zoonotic disease is discussed again in the light of current literature. Materials and Methods: Pregnant women with hydatid cyst monitored in a tertiary health center between 2018 and 2020 were evaluated. Seven cases were included in this study. We retrospectively collected and analyzed clinical data, which did not interfere with medical treatment. Results: Albendazole was started as medical therapy in six patients, and percutaneous drainage was applied to one patient. Three of our six patients who started medical treatment had to undergo surgery due to maternal complications that developed despite medical treatment. Two of our patients were delivered with a cesarean section due to the obstetric indications. Discussion: Hydatid cysts are most commonly caused by Echinococcus granulosus infection and most common in the liver. The diagnosis of liver hydatid cysts is not difficult, but pregnant women’s treatment methods have some problems. Although both medical and surgical treatments are available, there is no consensus. We would also like to underscore that echinococcal disease of the liver should be kept in mind in the differential diagnosis of abdominal pain, jaundice, and/or fever, especially in endemic regions. We think that when we increase awareness about this disease, we can improve fetal and maternal outcomes by making an early diagnosis and management.     

Higher Seroprevalence of Hepatitis B Virus Antigen in Patients with Cystic Hydatid Disease than in Patients Referred to Internal Medicine Clinics in Turkey

Turkey remains an intermediate area for prevalence of hepatitis B virus (HBV) surface antigenemia. The sheep-raising areas of Turkey also pose a high risk for cystic hydatid disease (CHD). Both HBV infection and CHD are major public health issues particularly in eastern parts of Turkey; however, there is no data regarding HBV infection in patients who have had CHD. The aims of this study were to evaluate the association between HBV infection and CHD and suggest ways to reduce HBV infection which is still widespread in Turkey. A retrospective study was conducted with 94 adult patients with active CHD referred to the hepatology department, Yuzuncuyil University School of Medicine from December 2010 to December 2012. All subjects came from rural areas of the region and underwent ultrasonography of abdomen which detected CHD of the liver. All the patients were serologically positive for Echinococcus granulosus. The control group consisted of 500 patients (300 men and 200 women) referred to the internal medicine clinics for other reasons. The patients with CHD and in the control group were tested for the existence of HBs antigen according to the standard procedures. The seroprevalence of HBs antigen was significantly higher in patients with active CHD than those in the control group (12.7% vs 5.2%; P=0.0017). Our data indicate that there is significant association between HBV infection and CHD. All patients with CHD should be screened for HBV infection.     

Distribution and Identification of Root-knot Nematodes from Turkey

Root knot nematodes are causing serious losses in protected cultivation fields in the West Mediterranean region of Turkey. Correct and confident identification of the plant parasitic nematodes is important for vegetable growing and breeding. Therefore, ninety-five populations of plant parasitic nematodes were collected from regional greenhouses. Previously described species-specific primers were used to identify Meloidogyne populations. The present study indicated that SEC-1F/SEC-1R and INCK14F-INCK14R primers for identifying of M. incognita, Fjav/Rjav and DJF/DJR primers for M. javanica and Far/Rar for M. arenaria primers can be effective tools to identify the Turkish root-knot nematode species. Dissemination ratios of the population were 64.2%, 28.4% and 7.3% for Meloidogyne incognita, M. javanica and M. arenaria, respectively. The results showed that M. incognita was the prominent root-knot nematode species in the West Mediterranean coastal areas of Turkey.

Molecular diversity and phylogeography of Andricus curtisii (Hymenoptera,Cynipidae) in Turkey

A 433-bp fragment of the mitochondrial cytochrome b gene and the entire nuclear ITS2 region were sequenced in an oak gall wasp species, Andricus curtisii, which represents 21 populations across its range in Turkey. Forty cytochrome b haplotypes and 63 ITS2 alleles were discovered among the 161 individuals studied. Remarkable genetic variation was detected in the species, with an average haplotype diversity (h) of 0.72 and 0.76 and an average nucleotide diversity (π) of 0.06 and 0.01 for the cyt b gene and the ITS region, respectively. Most populations were genetically distinct, possessing unique cytochrome b haplotypes. Maximum likelihood and Bayesian phylogenetic analyses and application of the haplotype network to both datasets revealed that the most basally located haplotypes/alleles were from the eastern part of Turkey. The detection of older sequences in the phylogenetic trees of the easterly located populations implied an eastern origin of the species. The application of a conventional insect mitochondrial DNA clock to the dataset suggested a splitting of ingroup haplotypes from the outgroup lineages predating the Pleistocene epoch and the formation of two major haplogroups that coincided with the oscillation of the early Pleistocene glaciations.

Ethical Know-how and Traditional Ecological Knowledge in Small Scale Fisheries on the Eastern Black Sea Coast of Turkey

In the context of development and changes in two small-boat fisheries on the eastern Black Sea coast of Turkey, this article discusses how institutions are embedded in tradition, and what is “traditional” in “traditional knowledge”. Taking new institutional economics’ focus on institutions and approaches to traditional ecological knowledge as vantage points for discussion I compare systems of informal management in one discontinued and one new fishery to address questions such as: What kinds of knowledges and rules are involved in these kinds of fishing? What constitutes a tradition of knowledge? What is the role of tradition in working out new rules? I couple theories of situated knowledge (Ingold) and embeddedness of rules (Varela), both of which are inspired by Merleau-Ponty’s phenomenological approach, to show how institutions and traditional ecological knowledge are embedded and come together in practice.

Molecular screening of Leishmania spp. infection and bloodmeals in sandflies from a leishmaniasis focus in southwestern Turkey

Leishmaniasis is an arthropod‐borne disease that affects approximately 2 million people worldwide annually. The aims of this study were to detect the presence of Leishmania (Kinetoplastida: Trypanosomatidae) DNA and the feeding preferences of probable vector species in an endemic focus of Leishmania infantum in Turkey. Entomological sampling was performed in August and October 2015 in Ayd?n province, where cases of human and canine leishmaniasis have been reported previously. A total of 1059 sandfly specimens comprising nine species belonging to two genera, Phlebotomus and Sergentomyia (both: Diptera: Psychodidae), and five subgenera of the Phlebotomus genus (Phlebotomus, Paraphlebotomus, Larroussius, Adlerius and Transphlebotomus) were collected in five villages. Among all Phlebotomus specimens, Phlebotomus neglectus (39%) was noted as the most abundant species, followed by Phlebotomus tobbi (18%). Leishmania DNA was detected in pools from P. neglectus, P. tobbi and Sergentomyia dentata by kDNA polymerase chain reaction (PCR). Leishmania DNA from Phlebotomus specimens was identified as L. infantum, but Leishmania DNA from Sergentomyia spp. could not be identified to species level by ITS‐1 real‐time PCR. The detection of Leishmania DNA in wild‐caught P. neglectus and the high percentage (24.2%) of human DNA in engorged specimens suggests that P. neglectus is probably an important vector species for L. infantum in Ayd?n province.     

Molecular Analysis of the Interactions between Cyst Nematodes and Their Hosts

In order to complete its life cycle, a cyst nematode must stimulate the production of a specialized syncytial feeding site within host root tissues. This process is characterized by major changes in local root morphology, including enlargement of affected nuclei and nucleoli, cell wall degradation, and proliferation of subcellular organelles. At the molecular level very little is known about the processes involved in this host response, but recent evidence suggests that cyst nematodes are able to regulate specific host genes. The host-parasite model system provided by Arabidopsis thaliana and Heterodera schachtii will be fundamental to our future understanding of the formation of syncytia. Molecular biology now offers us the opportunity to study this complex host-parasite interaction in great detail. A better understanding of the host genes regulated by cyst nematodes and the mechanisms by which this regulation is achieved will facilitate the engineering of crop cultivars that possess novel forms of resistance to these adept parasites.     

Ooids from Turkey and Egypt in the Eastern Mediterranean and a love-story of Antony and Cleopatra

Summary Cleopatra’s beach is one of the most famous in Turkey for its distinctive white sand, composed largely of ooids. Legend has it that the Roman leader, Mark Antony, had this sand shipped from Alexandria in Egypt to create a beach for his lower Cleopatra, on Sedir Island in G?kova Bay, SE Aegean Sea. This study examines the reality of this leagend from a comparison of the oolitic sand from Cleopatra’s beach in Turkey with oolitic sand from the coast west of Alexandria in Egypt, the home city of Cleopatra, and only place in the Mediterranea where Holocene ooids occur in abundance. The ooids on Cleopatra’s beach gave a pale browncreamy colour and dull surface texture. Most grains are spherical, with nuclei of terrigenous grains, peloids and bioclasts. The Cleopatra ooids have all the features typical of high-energy, shallow-marine ‘classic” ooids, but they occur in a very low energy bay and shown evidence of being out place there (microborings, discolouration, dull surface). In terms of size, shape, cortex fabric and mineralogy, the Cleopatra ooids show great similarities to those from the northern coast of Egypt, west of Alexandria. The Alexandria ooids examined have a white-cream colour with a high polish, although there are fewer silicate nuclei compared to the Cleopatra ooids. On the basis of textures and microfabrics, the hydrographic conditions at G?kova bay, the relatively small quantity of oolitic sand in this tiny pocket beach and the absence of this type of sand any-where else in Turkey, it is concluded that the oolitic sand was brought to Cleopatra’s beach from somewhere else, and that the northern Egyptian coast was the most likely source. This lends credence to the Antony and Cleopatra story. Calculations suggest that some 15 Roman corn barges would have been required to transport the quantity of sand now present on the beach in Turkey.     

Association and in Silico Assignment of Sequences from Turkey BACs

Bacterial artificial chromosomes (BACs) provide an important resource in genetic mapping. An initial set of BACs corresponding to microsatellite markers in the turkey (Meleagris gallopavo) was isolated from the CHORI-260 turkey BAC library. The selected markers were distributed on both macro- and microchromosomes and included a genetically unlinked marker. End sequences were obtained for a subset of the recovered BACs and compared to the chicken whole genome sequence. Close association of the turkey BAC-end sequences and original marker sequences was generally conserved in the chicken genome. Gene content of the turkey BACs is predicted from the comparative sequence alignments.

Molecular Typing of Cyst‐Forming Nematodes Globodera pallida and G. rostochiensis,Using Real‐Time PCR and Evaluation of Five Methods for Template Preparation

Globodera pallida and G. rostochiensis are two cyst‐forming nematodes known to infest potato crops, causing severe economic losses worldwide. In this study, a real‐time TaqMan PCR assay was developed and optimized for the simultaneous detection of G. pallida and G. rostochiensis. The assay's analytical and diagnostic sensitivity and specificity were evaluated using reference isolates. Four different DNA extraction methods and one rapid crude template‐preparation procedure were compared in terms of extraction purity, efficiency for PCR applications, utility and cost. Extraction methods A and B included two commercially available kits that utilize silica columns and magnetic beads, respectively. Method C was based on DNA isolation using Chelex resin, and method D was a standard chemistry in‐house protocol. Procedure E included the direct use of crude mixture composed of disrupted cysts in Tris–EDTA buffer. The multiplex TaqMan PCR assay successfully discriminated the two nematode species from all reference cyst samples and its recorded diagnostic sensitivity (Dse) and specificity (Dsp) was 100%. On the contrary, in conventional (Co) PCR tests, the overall Dsp and Dse were lower and estimated at 94 and 87% for G. pallida, and 97 and 88% for G. rostochiensis, respectively. Spectrophotometric results showed that DNA extraction methods A, B and C yielded the purest DNA and gave the lowest mean C_t values as well as the most consistent results in Co PCR. Alternative crude preparation method E resulted in statistically similar and C_t values consistent with those obtained with methods A to C when tested by TaqMan PCR. The developed assay, using crude template‐preparation E, allows the simple, accurate and cost‐effective testing of a large number of cyst samples and can be applied in surveys and certification schemes.     

Molecular Polymorphism and Morphometrics of Species of the Heterodera avenae Group in Syria and Turkey

Molecular characterization of the three most common cereal cyst nematode species of the Heterodera avenae group (H. avenae, H. filipjevi, and H. latipons), originating from various locations in major cereal-cultivating areas in Syria and Turkey, showed distinct restriction fragment patterns of the ITS-rDNA following PCR amplification and RFLP digestion with four endonucleases (Hae III, Hinf I, Ita I, and Pst I). Genetic dissimilarity within H. avenae group populations increased in comparison with H. avenae and other species; it was 0.164 with H. filipjevi and 0.354 with H. latipons populations. No intraspecific polymorphism was observed within H. latipons or H. filipjevi populations. Principal component analysis revealed contrasted correlations among 12 morphological parameters of cysts and juveniles of the three Heterodera species that separated them and distinguished differences within populations of H. latipons. Our results showed a clear separation of the three cyst nematode species on cereal using a conventional method for classification and molecular tests, and confirmed the congruence between genetics and morphological traits.     

Molecular Identification and Genetic Diversity of Fusarium species Associated with Onion Fields in Turkey

To identify Fusarium species associated with diseases of root and basal plate of onion, surveys were conducted in seven provinces of Turkey in 2007. Samplings were performed in 223 fields, and 332 isolates belonging to 7 Fusarium spp. were obtained. The isolates were identified as F. oxysporum, F. solani, F. acuminatum, F. equiseti, F. proliferatum, F. redolens, and F. culmorum based on morphological and cultural characteristics. Also, species‐specific primers were used to confirm the identity of Fusarium species. F. oxysporum was the most commonly isolated species, comprising 66.57% of the total Fusarium species. F. redolens was identified for the first time in onion‐growing areas of Turkey. Selected isolates of each species were evaluated for their aggressiveness on onion plant. F. oxysporum, F. solani, F. acuminatum, F. proliferatum, and F. redolens were highly pathogenic, causing severe damping‐off on onion plants cv. Texas Early Grano. Inter‐simple sequence repeats (ISSR) markers revealed a high degree of intra‐ and interspecific polymorphisms among Fusarium spp.
