ABSTRACT
Hematologic, protein electrophoresis, serum biochemistry, and cholinesterase values were determined in 36 free-living black stork nestlings (Ciconia nigra) between 25 and 53 days of age in order to establish normal reference values for this population. The following values were evaluated: white blood cell counts, red blood cell counts, packed cell volume, hemoglobin, heterophils, lymphocytes, monocytes, eosinophils, prealbumin, albumin, alpha-globulin, beta-globulin, gamma-globulin, total protein, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatine kinase, calcium, phosphorus, iron, cholesterol, glucose, triglycerides, uric acid, urea, creatinine, total solids, bile acids, and butyrylcholinesterase. Sex-dependent differences were observed in hemoglobin, prealbumin, albumin, gamma-globulin, total protein, alkaline phosphatase, and triglycerides. Packed cell volume, butyrylcholinesterase, aspartate aminotransferase, creatine kinase, and creatinine increased with age, whereas albumin, mean cell volume, calcium, phosphorus, cholesterol, and total solids decreased with age. These hematologic and serum biochemistry values can be used as reference ranges in free-living black stork nestlings.

This article describes a new pentastomid species from the abdominal air sacs of a black vulture (Aegypius monachus Linnaeus, 1766) from central Spain. The parasite's morphological characteristics (as shown by light and scanning electron microscopy) suggest that it should be classified in the new genus. It is the third pentastomid species described in birds and the first for the Accipitridae. The mouth is almost terminal, there are 2 pairs of hooks behind the mouth, and the genital pore is immediately posterior to these structures, placing the new species within the Cephalobaenida. The anterior and posterior hooks are similar in size and are flanked by parapodial lob. Cuticular tubercles are absent, false annulations can be seen, and the parasite's eggs have 2 layers.

Se hace un recuento de la composición del anillo betalactámico y de la manera de actuar de los antibióticos como las penicilinas y las cefalosporinas. Se aborda el mecanismo de resistencia bacteriana por la producción de betalactamasa y se reafirman aspectos importantes en el uso y abuso de estos fármacos. Se analiza la importancia del conocimiento de las reacciones cruzadas entre penicilinas y cefalosporinas y lo incorrecto del uso del nombre penicilina para denominar la betalactamasa
