ABSTRACT

Updating the mosquito fauna occurring in a specific area is crucial, given that certain species serve as vectors capable of transmitting zoonotic arboviruses. This scientific note presents the first records of mosquitoes of the tribe Orthopodomyiini in the Yucatan Peninsula. Immature mosquitoes were collected on 2 occasions inside a large tree hole in Felipe Carrillo Puerto, Quintana Roo, Mexico. Thirteen adult specimens, reared from the immatures, were obtained and identified as Orthopodomyia kummi based on external characteristics of females and males. This species has been recorded in Panama, Costa Rica, El Salvador, Guatemala, Mexico, and marginally in the United States, but its presence in the Yucatan Peninsula had gone unnoticed until now. The knowledge about mosquitoes of the genus Orthopodomyia is limited, and their epidemiological importance remains uncertain. Therefore, further studies could provide insights into the ecological and infection dynamics associated with this species.

ABSTRACT

In bread wheat (Triticum aestivum L.), chromosome associations during meiosis are extremely regulated and initiate at the telomeres and subtelomeres, which are enriched in satellite DNA (satDNA). We present the study and characterization of the bread wheat satellitome to shed light on the molecular organization of wheat subtelomeres. Our results revealed that the 2.53% of bread wheat genome is composed by satDNA and subtelomeres are particularly enriched in such DNA sequences. Thirty-four satellite DNA (21 for the first time in this work) have been identified, analyzed and cytogenetically validated. Many of the satDNAs were specifically found at particular subtelomeric chromosome regions revealing the asymmetry in subtelomere organisation among the wheat subgenomes, which might play a role in proper homologous recognition and pairing during meiosis. An integrated physical map of the wheat satellitome was also constructed. To the best of our knowledge, our results show that the combination of both cytogenetics and genome research allowed the first comprehensive analysis of the wheat satellitome, shedding light on the complex wheat genome organization, especially on the polymorphic nature of subtelomeres and their putative implication in chromosome recognition and pairing during meiosis.

ABSTRACT

OBJECTIVE: Hip fracture (HF) in the elderly carries high mortality and decreases functionality and quality of life after one year. The aim of this paper was to identify risk factors that influenced functionality (Barthel) and quality of life (EQ-5D) of the elderly with osteoporotic HF. METHODS: A prospective observational study was made in people over 65 years of age with HF between October 2017 and November 2018. Clinical information was collected from the digital medical record and the scales were measured by telephone at four times: baseline, one month, six months and twelve months. Statistical analysis was made thanks to SPSS vs 25.0. Multivariate analysis was performed using a generalized linear model for repeated measures to determine the relationship of risk factors with functionality and quality of life. RESULTS: Functionality showed significant differences (p<0.001) between baseline measurement and one month (90 points vs 50); baseline and at twelve months (90 vs 60 points); and that of the month and at twelve months (50 points vs 60). Quality of life also presented significant differences (p<0.001) between baseline and one month (0.587 vs 0.113); and baseline and twelve months (0.220). The functionality should be in transfused and with high surgical risk (p<0.05) and the quality of life will arrive in high surgical risk (p=0.017). Those older than 85 years were the ones who recovered the least after one year, as well as patients with delirium on admission and those who received transfusions. Patients with iron therapy recovered better at six months compared to those who did not and maintained this improvement at twelve months. CONCLUSIONS: Among the main risk factors are advanced age, male sex, transfused, high surgical risk, delirium on admission and malnutrition.


OBJETIVO: La fractura de cadera (FC) en mayores de 65 años conlleva alta mortalidad y una disminución de la funcionalidad y la calidad de vida al año. El objetivo de este estudio fue identificar factores de riesgo que influyeran en la funcionalidad (Barthel) y en la calidad de vida (EQ-5D) en mayores de 65 años con FC osteoporótica. METODOS: Se realizó un estudio observacional prospectivo en mayores de 65 años con FC entre octubre de 2017 y noviembre de 2018. Desde la historia clínica digital se recogió la información clínica y telefónicamente se midieron las escalas en cuatro momentos: basal, un mes, seis meses y doce meses. El análisis estadístico se efectuó mediante el programa informático SPSS (versión 25.0). Se realizó análisis multivariante mediante un modelo lineal generalizado para medidas repetidas para determinar la relación de los factores de riesgo con la funcionalidad y la calidad de vida. RESULTADOS: La funcionalidad presentó diferencias estadísticamente significativas (p<0,001) entre la medición basal y al mes (90 puntos frente a 50), la basal y a los doce meses (90 frente a 60 puntos), y la del mes y a los doce meses (50 puntos frente a 60). La calidad de vida también presentó diferencias estadísticamente significativas (p<0,001) entre el basal y al mes (0,587 frente a 0,113) y la basal y a los doce meses (0,220). La funcionalidad disminuyó en transfundidos y con riesgo quirúrgico alto (p<0,05) y la calidad de vida decreció en riesgo quirúrgico alto (p=0,017). Los mayores de 85 años fueron los que menos recuperaron al año, al igual que los pacientes con delirium al ingreso y los transfundidos. Los pacientes con ferroterapia se recuperaron mejor a los seis meses respecto a los que no y mantuvieron esta mejoría a los doce meses. CONCLUSIONES: Entre los principales factores de riesgo están la edad avanzada, el sexo masculino, ser transfundidos, el riesgo quirúrgico alto, el delirium al ingreso y la desnutrición.

ABSTRACT

Aspergillus flavus and Aspergillus niger are fungi which can contaminate dried figs before and after harvest and consequently produce aflatoxins (AFs) and ochratoxin A (OTA). Many approaches have been applied to minimise the growth of these filamentous fungi, mainly involving the use of synthetic fungicides which are limited due to their negative impact on human health and the environment. In this context, biocontrol is a recent approach that needs to be explored. This study evaluated the potential of three volatile organic compounds (VOCs), octanoic acid (OA), 2-phenylethyl acetate (2PEA) and furfuryl acetate (FA), produced by Hanseniaspora uvarum and Hanseniaspora opuntiae yeasts on the growth, germination, gene expression and production of AFs and OTA by A. flavus M144 and A. niger M185 on dried fig-based agar and the incidence rates in dried figs. Two of the three VOCs evaluated (2PEA and FA) effectively controlled A. flavus M144 and A. niger M185 by using at least amounts of 50 µL (715 µL/L in the headspace) for FA and 100 µL (1430 µL/L in the headspace) for 2PEA in dried figs. One of the mode of actions of both compounds consists in early repressing the expression of genes involved in the biosynthesis of AFs (aflR) and OTA (pks) of A. flavus and A. niger, respectively. The results of this study support the application of 2PEA and FA at the early post-harvest stages of dried figs to control mycotoxin accumulation.

ABSTRACT

The processing of dried figs in the industry involves a number of stages that present a significant risk of filamentous fungal infection of the fruit and subsequent mycotoxin contamination, due to the changes in temperature and water activity (aw) to which dried figs are exposed. In this study, the environmental conditions and the physicochemical parameters of dried figs at different processing stages were evaluated in 3 different industries, and were associated with fungal counts and the presence of toxigenic moulds and their mycotoxins. For this, dried figs at 5 relevant stages of industrial processing (curing, sizing, blanching, storage, and final product) in 3 industries located in Extremadura (Spain) were sampled. Changes in moisture content and aw of dried figs during processing were observed and they influenced the mycological quality of figs. Among the fungal genera, Aspergillus spp. predominated in most stages except blanching, where Penicillium spp. prevailed. About 10% of the dried fig samples were contaminated with aflatoxins (AFs) and 6% with ochratoxin A (OTA). Based on findings, longer drying times are necessary after blanching to reduce aw and to avoid the development of toxigenic moulds. In addition, all stages covering industry processing, final storage, and retailing of dried figs are advisable to be conducted at refrigeration conditions and controlled relative humidity to avoid mycotoxin production. The enumeration of AFs- and OTA- producing moulds by real-time PCR seems to be a good indicator for integration into prevention strategies to control filamentous fungal hazards and subsequent mycotoxin synthesis during the processing of dried figs.

ABSTRACT

Aspergillus flavus is a toxigenic fungal colonizer of fruits and cereals and may produce one of the most important mycotoxins from a food safety perspective, aflatoxins. Therefore, its growth and mycotoxin production should be effectively avoided to protect consumers' health. Among the safe and green antifungal strategies that can be applied in the field, biocontrol is a recent and emerging strategy that needs to be explored. Yeasts are normally good biocontrol candidates to minimize mold-related hazards and their modes of action are numerous, one of them being the production of volatile organic compounds (VOCs). To this end, the influence of VOCs produced by Hanseniaspora opuntiae L479 and Hanseniaspora uvarum L793 on growth, expression of the regulatory gene of the aflatoxin pathway (aflR) and mycotoxin production by A.flavus for 21 days was assessed. The results showed that both yeasts, despite producing different kinds of VOCs, had a similar effect on inhibiting growth, mycotoxin biosynthetic gene expression and phenotypic toxin production overall at the mid-incubation period when their synthesis was the greatest. Based on the results, both yeast strains, H. opuntiae L479 and H. uvarum L793, are potentially suitable as a biopreservative agents for inhibiting the growth of A. flavus and reducing aflatoxin accumulation.

ABSTRACT

Dried fig is susceptible to infection by Aspergillus flavus, the major producer of the carcinogenic mycotoxins. This fruit may be contaminated by the fungus throughout the entire chain production, especially during natural sun-drying, post-harvest, industrial processing, storage, and fruit retailing. Correct management of such critical stages is necessary to prevent mould growth and mycotoxin accumulation, with temperature being one of the main factors associated with these problems. The effect of different temperatures (5, 16, 25, 30, and 37 °C) related to dried-fig processing on growth, one of the regulatory genes of aflatoxin pathway (aflR) and mycotoxin production by A. flavus, was assessed. Firstly, growth and aflatoxin production of 11 A. flavus strains were checked before selecting two strains (M30 and M144) for in-depth studies. Findings showed that there were enormous differences in aflatoxin amounts and related-gene expression between the two selected strains. Based on the results, mild temperatures, and changes in temperature during drying and storage of dried figs should be avoided. Drying should be conducted at temperatures >30 °C and close to 37 °C, while industry processing, storage, and retailing of dried figs are advisable to perform at refrigeration temperatures (<10 °C) to avoid mycotoxin production.

ABSTRACT

There is a growing interest in finding safe and natural anti-microbial compounds as a valid alternative to conventional chemical treatments for managing post-harvest fruit diseases. This study investigated the anti-fungal capacity of orange peel polyphenolic extract (OPE) against three relevant post-harvest fungal pathogens, Monilinia fructicola, Botrytis cinerea and Alternaria alternata. OPE extract at 1.5 g/L inhibited (100%) the mycelial growth and conidial germination of the three target fungi. At lower concentration, the effect varied, depending on the dose applied and target fungi. When the anti-fungal activity of the main phenolic compounds in sweet orange peel, namely, the flavonoids (naringin, hesperidin and neohesperidin) and phenolic acids (ferulic and p-coumaric), were evaluated, ferulic acid and p-coumaric acid displayed significantly higher inhibitory capacity in synthetic medium, while the activity of flavonoids was limited. Synergism between compounds was not detected, and the inhibitory activity of OPE may be attributed to an additive effect of phenolic acids. Interestingly, in peach-based medium, ferulic acid remained active against M. fructicola and A. alternata and was more efficient than p-coumaric to control B. cinerea. These results highlight peel orange waste as an excellent source of anti-fungal compounds, suggesting the possibility of using ferulic acid or ferulic acid-rich extracts, either alone or in combination with other post-harvest treatment, as a natural alternative to reduce post-harvest losses and, also, enhance the shelf-life of fruit.

ABSTRACT

Rotting caused by grey mould (Botrytis cinerea) is a concerning disease for numerous crops both pre- and postharvest stages. Application of antagonistic yeasts is a promising strategy for controlling grey mould incidence which could mitigate undesirable consequences of using synthetic fungicides. In this work, a screening for detection of yeasts isolated from figs producers of antifungal volatile organic compounds (VOCs) were performed by confrontation in double dishes systems. Eleven out of 34 yeasts confronted reduced B. cinerea growth parameter in vitro. This reduction was correlated (p ≤ 0.050) with the production of 10 volatile compounds: two acids (acetic acid and octanoic acid), 7 esters (Ethyl propionate, n-Propyl acetate, Isobutyl acetate, 2-methylbutyl acetate, furfuryl acetate, phenylmethyl acetate, 2-phenylethyl acetate) and one ketone (Heptan-2-one). In bases on in vitro assay, Hanseniaspora uvarum 793 was applied to in vivo assays with strawberries and cherries. The reduction of incidence of B. cinerea in strawberries at 7 °C and 25 °C was 54.9 and 72.1% after 6 and 3 days, respectively. The reduction of incidence of B. cinerea in cherries at 7 °C and 25 °C was 48.9 and 45.6% after 5 and 4 days, respectively. These results showed that VOCs produced by Hanseniaspora uvarum 793 are effective in the control of incidence of Botrytis cinerea in fruits, being a potential alternative to chemical fungicide.

ABSTRACT

Physicochemical and sensory properties of nine fig cultivars: 'San Antonio' (SA), 'Blanca Bétera' (BB), 'Brown Turkey' (BT), 'Tres Voltas L'Any' (TV), 'Banane' (BN), 'Cuello Dama Blanco' (CDB), 'Cuello Dama Negro' (CDN), 'Colar Elche' (CE), and 'De Rey' (DR), were compared at three different ripening stages. Weight, size, titratable acidity, pH, skin and flesh colours, firmness, maturation index (MI), and volatile compounds were determined in samples from two consecutive seasons, in addition to both descriptive and hedonic sensory analysis. The mechanical behaviour of figs determined by firmness analysis and colour changes in both skin and flesh was the most important trait for the discrimination of ripening stages. Notable differences among cultivars were found in most of the parameters studied, in particular the inter-cultivar differences highlighted for MI, pH, acidity, and skin colour analyses, followed by volatile compounds. Principal component analysis (PCA) indicated that MI, pH, colour parameters of flesh (h and L*), and terpenes were the best physicochemical indices to determine overall acceptability which is highly correlated with the sensory attributes flesh colour and fruit flavour. The results suggested that CDN and SA showed huge consumer acceptability among the fig cultivars studied.

ABSTRACT

Hantaviruses are transmitted by rodents producing the hantavirus pulmonary syndrome (HPS) in the Americas. Today, no human cases of HPS have been reported in Mexico in spite of similar environmental conditions with Central America and the USA where several cases have occurred. To understand the current situation of hantaviruses in Mexico and the public health risk, a systematic review of studies was conducted reporting hantaviruses in rodents to known state seroprevalence and hantavirus genotypes. Simultaneously, this study identified the potential hantaviruses based on the phylogenetic diversity (PD) of hantaviruses reported in the Americas in hosts with the distribution in Mexico. A total 3862 rodents belonging to 82 species have been tested since 1999 to 2017. Overall, 392 individuals representing 43 rodent species were seropositive, and the seroprevalence ranged from 0 to 69.22%. Seven hantaviruses genotypes have been described in Mexico and three are zoonotic. Four host species of rodents are widely distributed in Mexico harboring the highest PD of viruses. According to the hosts distribution, 16 genotypes could be circulating in Mexico and some of these represent a potential risk for public health. This study proposed multidisciplinary and interinstitutional collaborations to implement systematic surveillance in rodents.

ABSTRACT

Antecedentes y objetivos: Las pacientes con diabetes mellitus gestacional (DMG) presentan un mayor riesgo de desarrollar hipertensión arterial inducida por el embarazo (HIE). La monitorización ambulatoria de presión arterial (MAPA) ha sido usada para detectar HIE y preeclampsia, pero hasta la fecha no ha sido suficientemente estudiada en DMG. El objetivo del presente trabajo es identificar de forma precoz, en mujeres con DMG, perfiles de presión arterial (PA), detectados mediante MAPA, que pudieran definir una población de mayor riesgo de desarrollar HIE y preeclampsia. Material y métodos: Estudio prospectivo en 93 pacientes con PA normal con DMG. Se les implantó entre la semana 28-32 de gestación la MAPA durante 24h (Spacelabs 90207) y se analizaron variables clínicas, analíticas y resultados obstétricos y perinatales. Resultados: La edad media fue 34,8±4,39años. Cinco pacientes (5,4%) desarrollaron HIE. Encontramos niveles más elevados de HbA1c (p=0,005) y microalbuminuria (p=0,001) entre las que desarrollaron HIE. Las pacientes con patrón no dipper (50,5%) presentaron cifras de PAS nocturna (106,7 vs 98,4mmHg) y PAD nocturna (64,8 vs 57,2mmHg) más elevadas (p<0,001). Se observó menor peso al nacimiento (3.084,57 vs 3.323,7; p=0,021) y menor semana de gestación en el momento del parto (38,67 vs 39,27 semanas; p=0,04) en pacientes con patrón no dipper respecto al dipper. La PAS nocturna elevada se asoció con un incremento significativo de la probabilidad de HIE (OR: 1,18; IC95%: 1,00-1,39; p=0,043). Conclusiones: En la DMG existen alteraciones tensionales con un predominio de patrón no dipper de PA y con valores más elevados de PAS y PAD nocturnos, pudiendo ser estas alteraciones predictoras de HIE. Los valores elevados de PAS nocturna aumentan el riesgo de desarrollo de HIE. Se requieren futuros estudios para determinar la relación entre las alteraciones tensionales y las complicaciones maternas y perinatales


Background and objective: Gestational diabetes mellitus (GDM) is associated to an increased risk of pregnancy-induced hypertension (PIH). Ambulatory blood pressure monitoring (ABPM) has been used to detect PIH and preeclampsia, but few data are currently available on its use in women with GDM. The aim of this study was to achieve early identification in women with GDM of BP profiles (detected by ABPM) that could define a population at greater risk of developing PIH and preeclampsia. Material and methods: A prospective study of 93 normotensive women with GDM in whom 24-h ABPM was performed (using a Spacelabs 90207 monitor) at 28-32 weeks of pregnancy. Clinical and laboratory variable and obstetric and perinatal outcomes were analyzed. Results: Mean age was 34.8±4.39years, and 5.4% of patients developed PIH. Higher levels of HbA1c (P=.005) and microalbumin (P=.001) were seen in patients with PIH. Patients with non-dipper patterns (50.5%) had higher values of night-time systolic BP (106.7 vs 98.4mmHg) and night-time diastolic BP (64.8 vs 57.2mmHg) (P<.001). Lower birth weights (3,084.57 vs 3,323.7) (P=.021) and shorter gestational age at delivery (38.67 vs 39.27 weeks) (P=.04) were found in women with non-dipper pattern. High night-time systolic BP significantly increased the chance of developing PIH (OR: 1.18; 95%CI: 1.00-1.39; P=.043). Conclusions: Patients with GDM have BP changes, with predominance of the non-dipper pattern and higher night-time systolic and diastolic BP, changes that could be useful predictors of PIH. High night-time systolic BP values increase the risk of developing PIH. Further studies are needed to ascertain the relationships between BP changes and obstetric and perinatal complications

CONCLUSIONS: Patients with GDM have BP changes, with predominance of the non-dipper pattern and higher night-time systolic and diastolic BP, changes that could be useful predictors of PIH. High night-time systolic BP values increase the risk of developing PIH. Further studies are needed to ascertain the relationships between BP changes and obstetric and perinatal complications.

ABSTRACT

Serpa cheese is one of the traditional regional Portuguese cheeses having the Protected Denomination of Origin (PDO) designation. This study investigated the bacterial community in the traditional Portuguese Serpa cheese. The microorganisms identified at the end of ripening (30 days) mainly were lactic acid bacteria (LAB). Lactobacillus paracasei/Lactobacillus casei was the main species in cheese from PDO registered industries, whereas in non-PDO registered industries Lactobacillus brevis was highlighted, among other LAB. Enterobacteriaceae species were detected at 20% to 40% of the total isolates. The results obtained by high-throughput sequencing analysis confirmed that LAB was the main microbial group, with Lactococcus genus contributing to approximately 40% to 60% of the population, followed by Leuconostoc and Lactobacillus. The Enterobacteriaceae family was also important. The differences between bacterial communities from PDO and non-PDO registered industries suggest that the lack of regulation of the cheese-making practices may influence unfavorably. The new knowledge about bacterial diversity in Serpa cheese could be useful to set up new ripening conditions, which favor the development of desirable microorganisms. PRACTICAL APPLICATION: The control of the manufacturing process of traditional cheeses can be improved through the knowledge of the bacterial diversity that develops. Thus, the growth of desirable microorganisms can be promoted to homogenize the final product.

ABSTRACT

Leptospires are widespread spirochete bacteria that infect mammals, including rodents and humans. We investigated the presence of Leptospira antibodies in two species of rodents from San Pedro River Basin (SPRB) in northwestern Mexico as part of the black-tailed prairie dog ( Cynomys ludovicianus ) monitoring plan and the North American beaver ( Castor canadensis ) reintroduction program. We sampled a total of 26 black-tailed prairie dogs and three beavers during October-November 2015. We detected antibodies against Leptospira spp. by microagglutination test in 12 (46%) prairie dogs and in two (67%) beavers. The antibody titers for seropositive rodents varied from 1:100 to 1:200, but none of the animals showed clinical signs of disease. We found seven Leptospira spp. serogroups (Autumnalis, Australis, Bataviae, Canicola, Celledoni, Grippotyphosa, and Sejroe) circulating in rodent species in SPRB. We did not find any differences between sex and age concerning Leptospira-positive rodents. Our findings suggest the presence of endemic cycles and potential risks of Leptospira infection in both species from SPRB. Although the impact of this infection on threatened species remains unclear, human activities and environmental stress might facilitate the emergence or reemergence of leptospirosis disease as has been reported elsewhere.

ABSTRACT

Importance: As the minority population increases in the United States, the incidence of skin cancer has important public health consequences, including poor skin cancer outcomes, in part because of late-stage diagnosis. Therefore, it is important to identify obstacles in skin cancer prevention in these communities. Objective: To characterize skin cancer prevention and education needs in uninsured, minority, and immigrant communities in South Florida. Design, Setting, and Participants: At a large free medical clinic in Florida, a convenience sample of people completed a 23-question survey in English, Spanish, or Haitian Creole assessing their skin cancer risk perception, knowledge, sun protective behaviors and barriers, and desirable outreach methods. All participants were uninsured and living at least 200% below the federal poverty level. Participants were adults recruited from the general waiting room who understood 1 of the 3 languages and were not present for a scheduled dermatology visit. Main Outcomes and Measures: The survey used Likert-type scales, true or false, and yes or no questions. Data were analyzed with SPSS IBM statistical software (version 22) using 1-way analysis of variance, χ2 tests, and Pearson correlations. Results: Among the 219 people invited, 206 participants (mean [SD] age, 43 [13.2] years) completed the survey; 75% of respondents were women who usually worked indoors. Almost a quarter (49 [24.5%) had never heard of skin cancer or melanoma. Nearly half (89 [44.3%]) had never conducted a self-skin examination. One in 5 (41 [20.7%]) believed that people with dark skin cannot get skin cancer. Three quarters (156 [75.7%]) of respondents fell into the "low/inconsistent" sun protective behavior category. Barriers to sun-protective behaviors were "using sun protection is too hot" (75 participants [39.3%]) and "I forget." (72 [37.7%]). More than 85% (175 [87.9%]) wanted to learn more about how to prevent skin cancer. Watching a video (37.3%) and text messaging (30.8%) were identified as the most popular outreach methods. Conclusions and Relevance: Important barriers to skin cancer prevention were lack of knowledge, the belief that dark skin was protective, and using sun protection made them feel too hot. Skin cancer education and intervention efforts in uninsured, minority, immigrant populations may be provided by videos and text messaging.

ABSTRACT

Cryptosporidium parvum and C. hominis are the most relevant species of this genus for human health. Both cause a self-limiting diarrhea in immunocompetent individuals, but cause potentially life-threatening disease in the immunocompromised. Despite the importance of these pathogens, only one reference genome of each has been analyzed and published. These two reference genomes were sequenced using automated capillary sequencing; as of yet, no next generation sequencing technology has been applied to improve their assemblies and annotations. For C. hominis, the main challenge that prevents a larger number of genomes to be sequenced is its resistance to axenic culture. In the present study, we employed next generation technology to analyse the genomic DNA and RNA to generate a new reference genome sequence of a C. hominis strain isolated directly from human stool and a new genome annotation of the C. parvum Iowa reference genome.

ABSTRACT

Microsporidia are ubiquitous fungi with genomes that have undergone a strong reduction to the extreme cases of Encephalitozoon cuniculi and Encephalitozoon intestinalis. Genetic variability within species of the Encephalitozoon genus has been reported, with most of the studies based on the internal transcribed spacer (ITS) of the rDNA. However, in contrast to the picture of E. cuniculi and Encephalitozoon hellem, where different strains have been identified, no genetic variability has yet been observed in E. intestinalis. We have analysed tandem repeats included in putative coding sequences which could be used as polymorphic markers in E. intestinalis. Eight candidate loci (M2, M2A, M3, M5, M7, M7A, M8 and PTP1) were established and 9 E. intestinalis cultured strains from North America, South America and Europe were analysed. M2, M7 and PTP1 nucleotide sequences were identical among the different strains and the GenBank sequence. In contrast, we observed variants in 4 markers (M2A, M3, M7A and M8) which did not correspond to their respective reference sequences. The most noticeable finding was that with the M5 marker two genotypes were defined among the different strains studied, demonstrating genotypic variability of E. intestinalis. Although the diversity described is certainly not high, which can be explained by a lower chance of genetic variability in its minimal genome, we have demonstrated that polymorphisms actually exist in E. intestinalis. Epidemiological studies using this genetic marker should now be conducted to elucidate the genetic variability in E. intestinalis and improve our knowledge of the epidemiology of this microsporidia.

ABSTRACT

Chronic lymphocytic leukemia (CLL) is characterized by a highly variable clinical course. Del(11q) and del(17p), routinely studied by conventional G-banding cytogenetics (CGC) and fluorescence in situ hybridization (FISH), have been related to progression and shorter overall survival. Recently, array-based karyotyping has gained acceptance as a high-resolution new tool for detecting genomic imbalances. The aim of the present study was to compare genomic arrays with CGC and FISH to ascertain whether the current techniques could be substituted in routine procedures. We analyzed 70 patients with CLL using the Cytogenetics Whole-Genome 2.7M Array and CytoScan HD Array (Affymetrix), CGC and FISH with the classical CLL panel. Whereas 31.4% and 68.6% of patients presented abnormalities when studied by CGC and FISH, respectively, these rates increased when arrays were also analyzed (78.6% and 80%). Although abnormality detection is higher when arrays are applied, one case with del(11q) and three with del(17p) were missed by genomic arrays due to their limited sensitivity. We consider that the complete substitution of CGC and FISH by genomic arrays in routine laboratories could negatively affect the management of some patients harboring 11q or 17p deletions. In conclusion, genomic arrays are valid to detect known and novel genomic imbalances in CLL, but should be maintained as a complementary tool to the current techniques.
