High quality diet improves lipid metabolic profile and breeding performance in the blue-footed booby, a long-lived seabird

ERICK GONZALEZ MEDINA (2018, [Artículo])

Understanding the role of diet in the physiological condition of adults during reproduction and hence its effect on reproductive performance is fundamental to understand reproductive strategies in long-lived animals. In birds, little is known about the influence of the quality of food consumed at the beginning of the reproductive period and its short-term effects on reproductive performance. To assess the role of diet in the physiological condition of female blue-footed booby, Sula nebouxii (BFBO), during reproduction we evaluated whether individual differences in diet (assessed by using δ13C and δ15N values of whole blood from female birds and muscle tissue of the principal prey species) prior to egg laying and during incubation influenced their lipid metabolic profile (measured as triglyceride levels and C:N ratio) and their reproductive performance (defined by laying date, clutch size and hatching success). Females with higher δ15N values in their blood during the courtship and incubation periods had a higher lipid metabolic profile, earlier laying date, greater clutch size (2–3 eggs) and higher hatching success. Females that laid earlier and more eggs (2–3 eggs) consumed more Pacific anchoveta (Cetengraulis mysticetus) and Pacific thread herring (Opisthonema libertate) than did other females. These two prey species also had high amounts of lipids (C:N ratio) and caloric content (Kcal/g fresh weight). The quality of food consumed by females at the beginning of reproduction affected their physiological condition, as well as their short-term reproductive performance. Our work emphasizes the importance of determining the influence of food quality during reproduction to understand the reproductive decisions and consequences in long-lived animals. © 2018 González-Medina et al.

Conjuntos de dinoflagelados del Cretácico Inferior de Colombia

Assemblages of dinoflagellate from the Lower Cretaceous of Colombia

Maribel Reyes Tixteco (2023, [Tesis de maestría])

Los dinoflagelados se usan como indicadores en investigaciones ecológicas y son uno de los principales causantes de toxicidad en florecimientos algales nocivos (FANs). Estas microalgas producen quistes resistentes y fosilizables, los cuales son muy útiles como indicadores bioestratigráficos y paleoecológicos. Los dinoflagelados del Cretácico han sido ampliamente estudiados en estratos de latitudes medias y altas, pero los conjuntos tropicales casi no han sido estudiados. Para ayudar a remediar esta falta de conocimiento, se estudiaron cuantitativamente y cualitativamente el contenido de dinoflagelados de 50 muestras de núcleos de los pozos ANH-CR-MONTECARLO-1X y ANH-CON-06-ST-S, localizados en Colombia. La edad de la sedimentación en ambos pozos se interpreta como Albiano, aunque hay un poco de incertidumbre en la edad de inicio. Los taxones heterotróficos tienen menor riqueza de especies, pero presentan mayor abundancia, mientras que los autótrofos tienen mayor riqueza de especies pero menor abundancia. En el pozo ANH-CR-MONTECARLO-1X se identificaron 20 géneros y 24 especies, con altos valores de concentración total de 1,441.00 qst / gr sed, en la muestra IIES-PALY-6015 por la presencia de Subtilisphaera y 1,036.88 en la muestra IIES-PALY-6021 dominada por Muderongia. Dichas muestras son correlacionables con dos transgresiones marinas, del Albiano tardío (104.4 Ma) y el Albiano temprano (111 Ma) respectivamente. Además, indican que los ensamblajes de quistes en este pozo, están dominados por formas Peridinoideas y Ceratioideas. En el pozo ANH-CON-06-ST-S se encontraron 16 géneros y 15 especies, con un valor máximo de 3,539.62 qst / gr sed en la muestra IIES-PALY-5995 por el alto contenido de Subtilisphaera, y correlacionable con la transgresión marina del Albiano tardío (104.4 Ma). Los ensamblajes de quistes en este pozo, están dominados por las formas Peridinoideas. La litología y el contenido de palinomorfos de los pozos indican un ambiente nerítico interno (NI) a transicional (T), con mayor aporte de terrígenos en el pozo ANH-CON-06-ST-S. Se propone un clima cálido para el Cretácico Inferior por la alta diversidad de taxones autótrofos característicos de aguas cálidas y estratificadas.

Dinoflagellates produce resistant and fossilizable cysts, which are useful as biostratigraphic and paleoecological indicators. These microalgae are used as indicators in ecological studies and are one of the main causes of toxicity in harmful algal blooms (HABs). Cretaceous dinoflagellates have been extensively studied in mid- and high-latitude strata, but tropical assemblages have hardly been studied. To help remedy this lack of knowledge, the dinoflagellate content of 50 core samples from the ANH-CR-MONTECARLO-1X and ANH-CON-06-ST-S wells, located in Colombia, were quantitatively and qualitatively studied. The age of sedimentation in both wells is interpreted as Albian, although there is some uncertainty in the beginning of the depositional age. Heterotrophic taxa have lower species richness but higher abundance, while autotrophs have higher species richness but lower abundance. In the ANH-CR-MONTECARLO-1X well, 20 genera and 24 species were identified, with high total concentration values of 1,441.00 cst / gr sed, in the IIES-PALY-6015 sample, due to the presence of Subtilisphaera and 1,036.88 in the IIES sample -PALY-6021, dominated by Muderongia. These samples are correlable with two marine transgressions, from the late Albian (104.4 Ma) and early Albian (111 Ma) respectively. Furthermore, they indicate that the cyst assemblages in this well are dominated by hetrotrophic forms. In the ANH-CON-06-ST-S well, 16 genera and 15 species were found, with a maximum value of 3,539.62 qst / gr sed in the IIES-PALY-5995 sample due to the high content of Subtilisphaera, and correlated with the transgression marina from the late Albian (104.4 Ma). The cyst assemblages in this well are also dominated by the heterotrophic forms. The lithology and palynomorph content of the wells indicate an internal neritic (NI) to transitional (T) environment, with a higher terrigenous influx in the ANH-CON-06-ST-S well. A warm climate is proposed for the Lower Cretaceous due to the high diversity of autotrophic taxa characteristic of warm and stratified waters.

Phylogenetic relationships of Pseudo-nitzschia subpacifica (Bacillariophyceae) from the Mexican Pacific, and its production of domoic acid in culture

Sonia Quijano (2020, [Artículo])

Pseudo-nitzschia is a cosmopolitan genus, some species of which can produce domoic acid (DA), a neurotoxin responsible for the Amnesic Shellfish Poisoning (ASP). In this study, we identified P. subpacifica for the first time in Todos Santos Bay and Manzanillo Bay, in the Mexican Pacific using SEM and molecular methods. Isolates from Todos Santos Bay were cultivated under conditions of phosphate sufficiency and deficiency at 16°C and 22°C to evaluate the production of DA. This toxin was detected in the particulate (DAp) and dissolved (DAd) fractions of the cultures during the exponential and stationary phases of growth of the cultures. The highest DA concentration was detected during the exponential phase grown in cells maintained in P-deficient medium at 16°C (1.14 ± 0.08 ng mL-1 DAd and 4.71 ± 1.11 × 10−5 ng cell-1 of DAp). In P-sufficient cultures DA was higher in cells maintained at 16°C (0.25 ± 0.05 ng mL-1 DAd and 9.41 ± 1.23 × 10−7 ng cell-1 of DAp) than in cells cultured at 22°C. Therefore, we confirm that P. subpacifica can produce DA, especially under P-limited conditions that could be associated with extraordinary oceanographic events such as the 2013–2016 "Blob" in the northeastern Pacific Ocean. This event altered local oceanographic conditions and possibly generated the presence of potential harmful species in areas with economic importance on the Mexican Pacific coast. © 2020 Quijano-Scheggia et al.

Protein retention assessment of four levels of poultry by-product substitution of fishmeal in rainbow trout (Oncorhynchus mykiss) diets using stable isotopes of nitrogen (δ15N) as natural tracers

DANIEL BADILLO ZAPATA (2014, [Artículo])

This is second part from an experiment where the nitrogen retention of poultry by-product meal (PBM) compared to fishmeal (FM) was evaluated using traditional indices. Here a quantitative method using stable isotope ratios of nitrogen (δ15N values) as natural tracers of nitrogen incorporation into fish biomass is assessed. Juvenile rainbow trout (Oncorhynchus mykiss) were fed for 80 days on isotopically distinct diets in which 0, 33, 66 and 100% of FM as main protein source was replaced by PBM. The diets were isonitrogenous, isolipidic and similar in gross energy content. Fish in all treatments reached isotopic equilibrium by the end of the experiment. Two-source isotope mixing models that incorporated the isotopic composition of FM and PBM as well as that of formulated feeds, empirically derived trophic discrimination factors and the isotopic composition of fish that had reached isotopic equilibrium to the diets were used to obtain a quantitative estimate of the retention of each source of nitrogen. Fish fed the diets with 33 and 66% replacement of FM by PBM retained poultry by-product meal roughly in proportion to its level of inclusion in the diets, whereas no differences were detected in the protein efficiency ratio. Coupled with the similar biomass gain of fishes fed the different diets, our results support the inclusion of PBM as replacement for fishmeal in aquaculture feeds. A re-feeding experiment in which all fish were fed a diet of 100% FM for 28 days indicated isotopic turnover occurred very fast, providing further support for the potential of isotopic ratios as tracers of the retention of specific protein sources into fish tissues. Stable isotope analysis is a useful tool for studies that seek to obtain quantitative estimates of the retention of different protein sources. © 2014 Badillo et al.

GEORGINA ROMERO GENARO (2023, [Otro, Trabajo terminal, especialidad])

El Acinetobacter es un cocobacilo aerobio gramnegativo que se ha descrito desde un

organismo de patogenicidad cuestionable hasta el de un agente infeccioso de gran

importancia hospitalaria en todo el mundo y se presenta en pacientes susceptibles con

mayor frecuencia en las unidades de cuidados intensivos (UCI). En nuestro país existen

estudios relacionado con este microorganismo que sustenta la importancia de la

prevención.

Este trabajo de investigación titulado “Prevención por acinetobacter baumannii en la

unidad de cuidados intensivos de un hospital de segundo nivel de atención”, tiene como

objetivo prevenir las infecciones asociadas por Acinetobacter baumannii. Mediante tres

variables las cuales son: higiene de manos, limpieza y desinfección de material y equipo

y la técnica de barrera máxima.

Se realizó un estudio de tipo cuantitativo, descriptivo y observacional. La muestra de

estudio está conformada por 30 profesionales de enfermería que se encuentran adscritas

a la UCI. Se realiza una evaluación de conocimientos a través de un instrumento sobre

las medidas de prevención que consta de 10 preguntas con opción multiple donde los

criterios de evaluación son: muy bueno, bueno y deficiente esta medición sustenta la

necesidad de la realización de este estudio. Con respecto al conocimiento que tiene el

personal profesional de enfermería encuestado sobre la eficiencia de las medidas de

prevención por acinetobacter baumannii se obtuvo un indicador de eficiencia general

bueno de un 72%. Los resultados por variable fueron los siguientes: el 80% fue de

conocimiento, el 63% al lavado de manos, 72% corresponde a la limpieza y desinfección

del material y equipo así como por último se obtuvo el 80% en la técnica de barrera

máxima.

Estos resultados nos permiten implementar las medidas preventivas mediante la difusión

con base en la NOM-045-SSA-2015 para la vigilancia epidemiológica, prevención y

control de las infecciones asociadas a la atención de la salud, al personal de enfermería

de la UCI.

Acinetobacter is a gram-negative aerobic coccobacillus that has been described from an

organism of questionable pathogenicity to that of an infectious agent of great hospital

importance worldwide and occurs in susceptible patients more frequently in intensive care

units (ICU). In our country there are studies related to this microorganism that support the

importance of prevention.

This research work entitled "Prevention of Acinetobacter baumannii in the intensive care

unit of a second level care hospital", aims to prevent infections associated with

Acinetobacter baumannii. By means of three variables which are: hand hygiene, cleaning

and disinfection of airway material and equipment and the maximum barrier technique.

A quantitative, descriptive and observational study was carried out. The study sample

consisted of 30 nursing professionals assigned to the ICU. Knowledge was evaluated by

means of an instrument on prevention measures consisting of 10 multiple-choice

questions where the evaluation criteria are: very good, good and deficient, this

measurement supports the need to carry out this study. With respect to the knowledge

that the professional nursing personnel surveyed have about the efficiency of

acinetobacter baumannii prevention measures, a good overall efficiency indicator of 72%

was obtained. The results by variable were as follows: 80% were for knowledge, 63% for

hand washing, 72% for cleaning and disinfection of material and equipment, and 80% for

the maximum barrier technique.

These results allow us to implement preventive measures through dissemination based

on NOM-045-SSA-2015 for epidemiological surveillance, prevention and control of

healthcare-associated infections, to ICU nursing staff.
