Technological advancements have changed the way clinical microbiology laboratories are detecting and identifying bacterial, viral, parasitic, and yeast/fungal pathogens. Such advancements have improved sensitivity and specificity and reduce turnaround time to reporting of clinically important results. This article discusses and reviews some traditional methodologies along with some of the technological innovations introduced into diagnostic microbiology laboratories. Some insight to what might be available in the coming years is also discussed.

ResumenRodriguez, A.M.; Odeon, A.C.; Louge, E.L.: Casos inusuales de colibacilosis septicémica en terneros neonatos de cría para carne. Rev. Vet. 30: 2, XX-XX, 2019. La colibacilosis septicémica es causada por Escherichia coli y suele afectar a terneros de tambo. El objetivo de este trabajo fue describir casos de colibacilosis en terneros de cría para carne. Las terneras afectadas (casos A y B) tenían 4 y 3 días de vida, eran hijas de vaquillonas y nacieron por parto distócico. El rodeo estaba en un rastrojo de maíz y en una pastura polifítica con escasa cobertura vegetal del suelo, debido al anegamiento por las intensas lluvias. Los signos clínicos y lesiones fueron similares en ambos casos e incluyeron decaimiento, hipopión, dificultad para desplazarse, deshidratación, disnea, poliartritis e hiperemia de vasos esclerales. Ambos animales desarrollaron leucocitosis y neutrofilia, con formas inmaduras en el caso A, en el cual se aisló E. coli de fluidos corporales, hígado, bazo y pulmón, recolectados a la necropsia, observándose aumento del volumen de líquido sinovial, con presencia de coágulos de fibrina. En el caso B se aisló E. coli a partir de sangre entera. Los aislamientos efectuados en diferentes órganos (caso A) y sangre (caso B) fueron sensibles a gentamicina, ciprofloxacina y minociclina. La ternera del caso B respondió favorablemente al tratamiento, durante 3 días, con gentamicina, enrofloxacina, meglumina de flunixin y sales rehidratantes orales. No se volvieron a observar casos similares durante la parición. Esta enfermedad debería considerarse en el diagnóstico diferencial de mortalidad neonatal en terneros de rodeos para carne, fundamentalmente cuando ocurren los factores predisponentes mencionados. Rev. Vet. 30: 2, XX-XX, 2019. Septicemic colibacillosis is a disease caused by Escherichia coli, and dairy calves are usually affected. The aim of this study was to describe cases of colibacillosis in beef calves. Two calves (cases A and B) aged 4 and 3 days, were born from heifers that suffered dystocia. The herd was grazing maize stubble and a polyphytic pasture with scarce vegetation covering the soil, because of intense rains flooded the field. The clinical signs and lesions were similar in both cases, and included depression, hypopyon, reluctance to move, dehydration, dyspnea, polyarthritis and hyperemia of scleral vessels. Both cases exhibited leukocytosis Revista Veterinaria Rev.

The objective of this study was to evaluate the usefulness of inflammatory markers as a diagnostic and prognostic approach in neonatal calves with septicaemia. The study material consisted of 13 neonatal calves with septicaemia (septicaemic calves, SC) and ten healthy neonatal calves (control calves, CC). Blood samples were collected for biochemical, haematological and microbiological analyses. In addition, faecal samples were collected for microbiological and virological analyses. Three of neonatal calves with septicaemia were positive for E. coli (E. coli O157 serotype) by microbiological examination, but all neonatal calves with septicaemia were negative for rota-and coronaviruses. By haematological examination, there were no significant differences between SC and CC for white blood cell (WBC) and neutrophil (NEU) counts (P > 0.05). NEU counts were higher on day 0 than on day 15 in SC (P < 0.05). Red blood cell (RBC) counts and packed cell volume (PCV) values were higher on day 0 in the SC than in the CC (P < 0.05). By biochemical analyses, tumour necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), procalcitonin (PCT), haptoglobin (Hp), and fibrinogen (Fb) concentrations were higher on day 0 in the SC than in the CC (P < 0.05). After treatment (on day 15), the serum IL-6, PCT, Hp, and Fb concentrations were significantly decreased in the SC compared to the CC (P < 0.05). The serum iron (Fe) concentrations were lower on day 0 in the SC than in the CC (P < 0.05), and were higher on day 15 than on day 0 in the SC (P < 0.05). The study revealed that inflammatory markers could be used for determining the diagnosis and prognosis in neonatal calves with septicaemia.
